ESBO Epoxidized Soybean Oil, known as Epoxidized Soybean Oil in Turkish, is a biobased epoxidized vegetable oil obtained by converting unsaturated carbon-carbon double bonds in soybean oil into epoxide groups. Its most important use is as a secondary plasticizer, auxiliary heat and light stabilizer, and hydrogen chloride scavenger additive in PVC formulations.
ESBO is the common abbreviation for Epoxidized Soybean Oil. In chemical inventories, Soybean Oil is also identified by the name Epoxidized. CAS No is 8013-07-8 and EC/EINECS No is 232-391-0.
ESBO Epoxidized Soybean Oil does not consist of a single pure molecule. Soybean oil is naturally a mixture of triglycerides containing different fatty acid chains. After the epoxidation process, a certain part of the carbon-carbon double bonds present in these triglycerides are converted into oxirane rings. Therefore, the commercial ESBO Epoxidized Soybean Oil product does not have a single, precise molecular formula or single molecular weight.
One of the most important parameters that determine the quality and performance of ESBO Epoxidized Soybean Oil is the amount of oxirane oxygen. Oxirane oxygen indirectly indicates the amount of epoxide rings formed in the oil structure. Approximately 6.5–7.0% of oxirane oxygen can be seen in commercial high-quality ESBO Epoxidized Soybean Oil products.
Cargill Vikoflex 7170 epoxidized soybean oil reports an oxirane content of over 6.8%, a viscosity of approximately 320–500 mPa·s at 25 °C, a specific gravity of approximately 0.99, a color below 150 APHA, a moisture content of less than 0.1%, an acid value of less than 0.5 mg KOH/g, and an iodine value of less than 3.
For ESBO Epoxidized Soybean Oil, it publishes typical values such as approximately 7.0% oxirane oxygen, 0.28 mg KOH/g acid value, 0.90 iodine number, 0.991 specific gravity and approximately 3.4 Stokes viscosity at 25 °C. These figures refer to specific commercial grades and should not be generalized to all ESBO Epoxidized Soybean Oil products.
One of the important functions of ESBO Epoxidized Soybean Oil in PVC is its ability to bind hydrogen chloride. When PVC begins to degrade under high temperature, HCl can be released. The HCl formed can further accelerate degradation. The epoxide groups in ESBO Epoxidized Soybean Oil can react with acidic degradation products, helping to slow down this autocatalytic degradation mechanism.
For this reason, ESBO Epoxidized Soybean Oil is not just a plasticizer. It can provide important synergy as an auxiliary stabilizer in combination with calcium-zinc, organotin or other suitable PVC stabilizer systems.
ESBO Epoxidized Soybean Oil can also contribute to the flexibility of PVC. However, in many flexible PVC systems, it is not used as a replacement for the entire main plasticizer. It can be used as a secondary plasticizer in combination with DOTP, DINP, TOTM, DOA or other main plasticizers.
The vegetable oil origin of ESBO Epoxidized Soybean Oil provides a significant advantage in the development of phthalate-free or bio-based additive systems. However, being "biobased" alone is not a guarantee of regulatory compliance or environmental superiority in all areas of use.
Apart from PVC, ESBO Epoxidized Soybean Oil can also be used in coatings, adhesives, inks, rubber systems, lubricants, pigment dispersions, chemical intermediates and different polymer formulations.
When purchasing ESBO Epoxidized Soybean Oil, oxirane oxygen, iodine value, acid value, moisture, color, viscosity, density, refractive index, low temperature behavior, food contact suitability and batch COA values should be evaluated together.
WHAT IS ESBO EPOXIDIZED SOYBEAN OIL?
ESBO Epoxidized Soybean Oil is epoxidized soybean oil. The starting raw material is soybean oil.
Soybean oil is a mixture of natural triglycerides.
The triglyceride structure has three fatty acid chains attached to the glycerol backbone. These fatty acids are in different proportions:
Linoleic acid
Oleic acid
Linolenic acid
Palmitic acid
May contain stearic acid and other fatty acids.
Carbon-carbon double bonds are found in the oleic, linoleic, and linolenic acid chains.
In the epoxidation process, a significant part of these double bonds are converted into three-membered oxirane rings.
At the end of this reaction, Epoxidized Soybean Oil is obtained.
Simplified: The epoxide ring conversion takes place → the C=C double bond.
The epoxide ring is a three-membered ring consisting of two carbon and one oxygen atom.
This ring has a high tensile structure.
It can react with acids and other suitable reagents.
The PVC stabilization ability of ESBO Epoxidized Soybean Oil is largely due to these epoxide groups.
The CAS No of ESBO Epoxidized Soybean Oil is 8013-07-8. The EC/EINECS No is 232-391-0.
ECHA describes the substance as Soybean Oil, Epoxidized.
EPA also gives molecular formula information as "unspecified".
This is because ESBO Epoxidized Soybean Oil is not a single pure molecule, but a mixture of epoxidized triglycerides derived from variable fatty acid composition.
Accordingly, the C57H98O12 or similar single formulations for ESBO Epoxidized Soybean Oil as appearing in certain internet sources do not accurately represent all commercial ESBO Epoxidized Soybean Oil products.
These can only indicate certain model triglyceride structures.
The only molecular formula of ESBO Epoxidized Soybean Oil on the technical product sheet is: Not defined.
The only definite molecular weight: It is not defined. It is more accurate to give it as follows.
ESBO Epoxidized Soybean Oil is mostly light yellow, clear or slightly yellowish, viscous oily liquid.
It is liquid at room temperature. It is insoluble in water.
It can have good compatibility with many organic and polymeric systems.
It has a high technical value, especially in plasticized PVC.
The main functions of ESBO Epoxidized Soybean Oil are:
Secondary plasticization
Contribution to heat stabilization
Contribution to light stabilization
HCl retention
Acid retention
Delaying PVC degradation
Pigment wetting
Viscosity regulation
Lubricity
Chemical intermediate function
can be summarized as.
ESBO defines Epoxidized Soybean Oil as a plasticizer and co-stabilizer in flexible and semi-rigid PVC formulations.
The same manufacturer also positions the product as a viscosity regulator or reactive diluent in epoxy, polyurethane, UV-curing resins, acrylic systems, PVA emulsions, alkyds, and polyesters.
ESBO Epoxidized Soybean Oil's triglyceride structure sets it apart from classic low molecular weight epoxy diluents.
ESBO Epoxidized Soybean Oil can be used in an epoxy formulation, but it does not have the same epoxy functionality, epoxy equivalent weight, or curing behavior as standard DGEBA type epoxy resin.
Therefore, the term "epoxy oil" does not mean that ESBO Epoxidized Soybean Oil can be used one-to-one instead of standard epoxy resin.

CHEMICAL STRUCTURE AND MOLECULAR PROPERTIES OF ESBO EPOXIDIZED SOYBEAN OIL
The basic molecular skeleton of ESBO Epoxidized Soybean Oil is its triglyceride structure.
The glycerol backbone carries three fatty acid chains.
Soybean oil contains a significant amount of unsaturated fatty acids.
The double bonds in these fatty acids are the reactive sites for epoxidation.
As a result of epoxidation, the C=C bond turns into a three-membered oxirane ring.
Simplified conversion:
-C=C-
→
-C-C-
\ /
O
It can be thought of as.
Whether this transformation is successful or not can be followed by two basic analytical parameters.
The first is the amount of oxirane oxygen The second is the iodine value.
As soybean oil epoxidizes:
Oxirane oxygen rises.
Iodine value decreases.
Because the iodine value is related to the amount of carbon-carbon double bonds remaining.
The high degree of epoxidation is generally characterized by high oxirane oxygen and low iodine value.
Therefore, it is important to consider these two parameters together in the procurement specification.
For ESBO Epoxidized Soybean Oil:
Oxirane content: >6.8%
Iodine value: 3.0<
values.
For Hallstar Plasthall ESO:
Oxirane oxygen: approx. 7.0%
Iodine number: approx. 0.90
typical values are specified.
These differences may depend on the production process and product grade.
The high oxirane content is generally considered positive for its PVC stabilization capacity.
Because more epoxide function can react with HCl and other acidic species.
However, performance does not depend solely on the oxirane value.
Compatibility with PVC

and polymer formulation
together are important.
ESBO Epoxidized Soybean Oil has long hydrocarbon regions thanks to its triglyceride chains.
This structure provides plasticizing character.
Epoxide groups, on the other hand, increase the polarity and reactivity of the molecule.
Hence ESBO Epoxidized Soybean Oil within the same molecular system:
It has oil-like flexible chain and reactive epoxy functions.
This dual property is the primary reason why ESBO Epoxidized Soybean Oil acts as both a plasticizer and stabilizer additive in PVC.
Here are the key properties of ESBO Epoxidized Soybean Oil at the molecular level:
Carrying triglyceride structure
Being of vegetable oil origin
Containing epoxidized unsaturated fatty acid chains
Being able to carry more than one oxirane ring
Being able to react with acidic species
To be compatible with PVC
To be able to provide a plasticizing effect
Showing low volatility
Have high boiling and glowing behavior
To be able to be used as a reactive chemical intermediate

For Bisley's commercial ESBO Epoxidized Soybean Oil product, approximately 6.5% oxirane oxygen, ≤3 iodine value, approximately 0.998 specific gravity, and 1.470–1.475 refractive index are given.
Therefore, the manufacturer TDS/COA should be based on the purchase specification.
HOW DOES ESBO EPOXIDIZED SOYBEAN OIL WORK AT THE MOLECULAR LEVEL?
The working mechanism of ESBO Epoxidized Soybean Oil in PVC is based on two primary effects.
The first is the plasticizing effect.
The second is the stabilizing effect of epoxide groups.
PVC chains contain polar C-Cl bonds.
Pure PVC is thermoplastic with a rigid and high glass transition temperature.
When plasticizer molecules enter between PVC chains, the interaction between the chains decreases.
Chain mobility increases.
The glass transition temperature decreases.
The material becomes more pliable.
The long fatty acid chains of ESBO Epoxidized Soybean Oil may contribute to this plasticizing behavior.
However, ESBO Epoxidized Soybean Oil is not used as the sole main plasticizer in most flexible PVC formulations.
It acts as a secondary plasticizer that supports the main plasticizer.
The second mechanism is associated with the thermal degradation of PVC.
PVC can undergo a dehydrochlorination reaction at high temperature.
HCl is separated from the polymer chain.
Polyene structures containing double bonds are formed.
Color change begins.
The released HCl catalyzes new degradation.
Therefore, the reaction can be self-accelerating.
The epoxide groups in ESBO Epoxidized Soybean Oil can react with HCl.
The free concentration of HCl may be reduced.
This can delay the acceleration of PVC degradation.
Simplified:
Epoxide group + HCl → chlorohydrin type reaction product
It can be thought of as.
This mechanism gives ESBO Epoxidized Soybean Oil an acid-retaining character.
ESBO describes Epoxidized Soybean Oil as an effective acid and mercaptan scavenger.
Metal-based stabilizers can also be found in the PVC formulation.
Calcium-zinc systems
Organotin stabilizers
and other suitable stabilizers
PVC acts at different stages of the degradation mechanism.
ESBO Epoxidized Soybean Oil can exhibit synergistic behavior when used in conjunction with these stabilizers.
For this reason, the stabilizing effect of ESBO Epoxidized Soybean Oil is not standalone, but is part of the whole stabilizer package in most formulations.
ESBO Epoxidized Soybean Oil can also regulate viscosity in oil-phase formulations.
It can wet the surface of pigment particles.
It can help dispersion.
In lubricant systems, polar epoxide groups and long hydrocarbon chains together can alter surface behavior.
In epoxy, polyurethane or other thermosetting chemistries, the epoxide groups of ESBO Epoxidized Soybean Oil can be used for chemical modification.
However, the reactivity of the triglyceride structure is not the same as that of standard small molecule epoxy resins.
The main functions of ESBO Epoxidized Soybean Oil at the formulation level are:
Contribution to plasticizing PVC
HCl retention
Supporting PVC thermal stability
Supporting light stability
Supporting the main stabilizer system
Viscosity regulation
Pigment wetting
Lubricity
Acid retention
Participation in reaction as a chemical intermediate
IN WHICH SECTORS IS ESBO EPOXIDIZED SOYBEAN OIL USED?

In its overall safety assessment, LANXESS states that ESBO Epoxidized Soybean Oil can be used as a plasticizer or stabilizer in plastics, adhesives and coatings; it can also be used as a chemical process regulator and industrial lubricant.
USE OF ESBO EPOXIDIZED SOYBEAN OIL AS PVC PLASTICIZER AND HEAT STABILIZER
PVC applications are the most important commercial use of ESBO Epoxidized Soybean Oil.
ESBO Epoxidized Soybean Oil mostly provides two basic tasks in PVC.
The main plasticizer provides flexibility by reducing the interaction between PVC chains.
ESBO Epoxidized Soybean Oil may also contribute to this effect.
However, in many formulations, the amount of ESBO Epoxidized Soybean Oil is kept lower than the main plasticizer.
For example:
DOTP
DINP
TOTM
DOA
DINCH
or other suitable main plasticizers.
Optimal usage level of ESBO Epoxidized Soybean Oil:
PVC type
Main plasticizer
Hardness target
Thermal Stabilizer Package
Food contact requirement
Processing temperature
and end use
It is determined through.
The thermal stabilizing effect of ESBO Epoxidized Soybean Oil is based on the HCl retention mechanism.
When the thermal degradation of PVC begins, hydrogen chloride is formed.
If HCl is not removed from the environment, it can accelerate chain degradation.
ESBO Epoxidized Soybean Oil's oxirane rings react with HCl, helping to retain acidic species.
Initial color stability may improve.
Thermal degradation may be delayed.
Process time may be extended.
The performance of the stabilizer package can be supported.
The reworkability of PVC can improve.
Cargill defines the product as a product that contributes to heat and light stabilization in flexible, semi-rigid and rigid PVC formulations.
Hallstar also states that ESBO Epoxidized Soybean Oil is an effective co-stabilizer in PVC and polychloroprene systems.
ESBO Epoxidized Soybean Oil can be used especially in Ca/Zn stabilizer systems.
The shift away from lead and some old heavy metal stabilizer systems in the PVC industry has increased the importance of auxiliary stabilizers such as ESBO Epoxidized Soybean Oil.
However, ESBO Epoxidized Soybean Oil should not be considered as the main stabilizer that meets all PVC stabilization needs alone.
It is usually used in a stabilizer package.
Other potential advantages of ESBO EPOXIDIZED SOYBEAN OIL in PVC:
Low volatility
Contribution to low migration behavior
Plant-derived carbon content
Phthalate-free construction
Flexibility
Ease of process
can be considered as.
However, the exact migration behavior depends on the entire formulation.
Main plasticizer
Quantity of ESBO Epoxidized Soybean Oil

Parameters such as affect migration.
USE OF ESBO EPOXIDIZED SOYBEAN OIL IN PVC PLASTIC, ARTIFICIAL LEATHER, CABLES AND GASKETS
In PVC plastisol formulations, ESBO Epoxidized Soybean Oil can be used as an auxiliary plasticizer and stabilizer.
The paste PVC particles are dispersed in the liquid plasticizer mixture.
ESBO Epoxidized Soybean Oil can form part of this liquid phase.
Plastisol viscosity:
Paste PVC grade
Main Plasticizer
ESBO Epoxidized Soybean Oil ratio

and temperature
determined by.
Therefore, when the amount of ESBO Epoxidized Soybean Oil rises, the rheology should be tested separately.
Flexibility and heat stability are important in faux leather formulations.
ESBO Epoxidized Soybean Oil can support the performance of the main plasticizer.
In flooring, it can also contribute to PVC stabilization during thermal treatment.
Thermal stability and long-term electrical performance are important in cable applications.
ESBO Epoxidized Soybean Oil can be used as an auxiliary plasticizer in suitable PVC cable formulations.
However, plasticizer migration and thermal aging properties should be tested separately in high-temperature cables.
Refrigerator and door seals require softness and long-term flexibility.
ESBO Epoxidized Soybean Oil can provide stabilization and secondary plasticization in such PVC systems.
ESBO Epoxidized Soybean Oil has been used in food jar lid seals since the past.
However, migration legislation is critical in this application.
For this reason, food contact suitability should be verified by migration tests on the exact recipe and final seal.
COATING, ADHESIVE, INK AND CHEMICAL INTERMEDIATE APPLICATIONS OF ESBO EPOXIDIZED SOYBEAN OIL
ESBO Epoxidized Soybean Oil can also be used in industrial systems other than PVC.
It can provide flexibility in coating systems.
It can change the resin viscosity.
Epoxide groups can participate in chemical modification reactions.
It can be evaluated as a reactive intermediate in alkyd and polyester resins.
It can be used as a biobased modification component in epoxy formulations.
The long fatty acid chains of ESBO Epoxidized Soybean Oil provide flexible character.
For this reason, it can provide a flexibility-enhancing effect in a hard and brittle thermoset structure.
But adding ESBO Epoxidized Soybean Oil to standard DGEBA epoxy resin:
Adjust the glass transition temperature
Hardness
Chemical Resistance
Curing speed
and cross-link density
can change.
For this reason, it should not be used uncontrollably for the purpose of reducing viscosity only.
It can be used for flexibility or rheology editing purposes in adhesives.
In pigment dispersions, its oily and polar character can help pigment surface wetting.
Cargill also positions the product as a pigment grinding fluid.
It can provide acid retaining function in inks.
Soy-based ink systems can benefit from the acid-accepting properties of ESBO Epoxidized Soybean Oil.
In lubricants, long hydrocarbon chains can contribute to lubricating behavior.
Epoxide groups, on the other hand, can be converted into other functional chemicals and used in the production of biobased polyols, coating resins, or specialty intermediates.
IS ESBO EPOXIDIZED SOYBEAN OIL USED IN FOOD, COSMETICS AND PHARMACEUTICAL APPLICATIONS?
ESBO Epoxidized Soybean Oil is not used directly as a foodstuff or as a food additive in the classical sense.
However, it can be used as a plastic additive in certain food contact materials.
This distinction is crucial.
In the European Union's current regulation (EU) No 10/2011 on plastic food contact materials, Epoxidized Soybean Oil:
FCM No 532
PM/REF 88640
CAS No 8013-07-8
It is listed as.
In the current EU regulation, the general specific migration limit is 60 mg/kg.
For PVC seals that seal glass jars containing certain infant and young children's foods, this limit is reduced to 30 mg/kg.
In the same arrangement, for ESBO Epoxidized Soybean Oil:
Oxiran <8%
Iodine count: 6<
conditions are specified.
Therefore, the statement "ESBO Epoxidized Soybean Oil is suitable for food contact" is not sufficient on its own.
Exact commercial grade must be appropriate.
The final PVC formulation must be appropriate.
The migration test should be performed under the necessary conditions.
The type of food must be taken into account.
Contact time should be taken into account.
Contact temperature should be taken into account.
In the United States FDA database, Epoxidized Soybean Oil is included in the food-related indirect use regulations with CAS No 8013-07-8.
The FDA registry lists relevant regulatory sections such as 21 CFR 172.723, 175.105, 175.300, 177.1650, 178.3910, and 181.27.
Compliance in these regulations should only be evaluated within the specified conditions of use.
The FDA listing of an ESBO Epoxidized Soybean Oil product does not imply unrestricted compliance with all food contact applications.
In cosmetic applications, ESBO Epoxidized Soybean Oil is not appropriate to be considered as the standard common INCI emollient.
If exact cosmetic use is considered, the current INCI and regulatory status should be checked separately.
For pharmaceutical use as well, general industrial ESBO Epoxidized Soybean Oil is not automatically pharmaceutical grade.
If intended for use in a medical device or pharmaceutical packaging system:
Impurity profile
Biocompatibility
Migration
extractables/leachables
GMP documents
and target legislation
It should also be evaluated.

Oxirane oxygen high grade generally has higher epoxy functionality.
However, product selection should not be made only by looking at the oxrane value.
For example, a low acid value is also important.
High free acid content may adversely affect PVC thermal stability or other formulation properties.
The amount of humidity should also be controlled.
Especially in sensitive polymer and reaction systems, water can cause unwanted side effects.
Color value is important in transparent or light PVC applications.
Dark ESBO Epoxidized Soybean Oil can create a yellow tint in the final product.
WHAT PROBLEMS CAN ESBO EPOXIDIZED SOYBEAN OIL HELP SOLVE?
ESBO Epoxidized Soybean Oil can help solve technical problems especially associated with PVC thermal stability, plasticizer system and the need for biobased additives.
PVC yellows prematurely during the process
ESBO Epoxidized Soybean Oil HCl can promote color stability with its retention and auxiliary stabilization effect.
PVC degrades thermally quickly
ESBO Epoxidized Soybean Oil in combination with the main stabilizer system can help improve thermal stability.
The performance of the Ca/Zn stabilizer system is insufficient
ESBO Epoxidized Soybean Oil can provide synergy as an auxiliary stabilizer.
PVC is not flexible enough
ESBO Epoxidized Soybean Oil can contribute to flexibility as a secondary plasticizer.
However, it should not be assumed that it will be used as a one-to-one replacement for the main plasticizer.
It is necessary to reduce the use of phthalates
ESBO Epoxidized Soybean Oil can be considered as a phthalate-free epoxidized vegetable oil option in a part of the formulation.
Biobased carbon rate is wanted to be increased
Due to the origin of soybean oil, suitable grades can contribute bio-based.
HCl formation in PVC creates problems
Epoxide groups can help bind acidic HCl.
The pigment does not get wet enough
ESBO Epoxidized Soybean Oil can be used as an auxiliary liquid in pigment dispersion.
The coating is too fragile
Fatty acid-based long chain structure can provide a flexibility-enhancing effect in certain resins.
Epoxy system is very hard
Modification with ESBO Epoxidized Soybean Oil can improve flexibility in some systems.
However, the full range of mechanical and thermal properties should be retested.
There is a migration problem in PVC
ESBO Epoxidized Soybean Oil may have the advantage of low volatility and favorable compatibility, but the actual migration depends on the whole formulation.
ESBO Epoxidized Soybean Oil migration is high in food contact PVC product
In this case, using more ESBO Epoxidized Soybean Oil is not the solution.

If there is an EU food contact application, FCM No 532 and current (EU) No 10/2011 conditions should be evaluated.
If there is a US application, the relevant 21 CFR sections should be examined together with the exact usage condition.
ESBO Epoxidized Soybean Oil should not be considered harmless because it is of vegetable origin.
Proper occupational hygiene should be applied as an industrial raw material.
Prolonged contact with eyes and skin should be avoided.
Spilled oily product can create a slippery floor.
Thermal degradation and fire conditions in high-temperature use should be evaluated according to SDS.
INITIAL FORMULATION APPROACHES FOR ESBO EPOXIDIZED SOYBEAN OIL

EXAMPLE 2: ESBO EPOXIDIZED SOYBEAN OIL PVC HEAT STABILIZATION SCREENING
Objective: To evaluate the contribution of ESBO Epoxidized Soybean Oil in combination with Ca/Zn stabilizer system on thermal color stability.
Starting components:
PVC: 100 phr
Main plasticizer (DOTP): 50, 47 or 44 phr
Ca/Zn stabilizer: 2 phr
ESBO Epoxidized Soybean Oil: 0, 3 or 6 phr
Lubricant system (suitable PVC internal/external lubricant mixture): 0.5 phr
Filler (dry calcium carbonate): 20phr
Total: 172.5 phr; 100% by weight in all samples.
Control formulation (% by weight): PVC 57.971%; DOTP 28.985%; Ca/Zn stabilizer 1.159%; ESBO 0.000%; lubricant 0.290%; calcium carbonate 11.595%. Total 100.000%.

The browning/decomposition time is compared.
Mechanical properties are checked.
The lowest effective level of ESBO Epoxidized Soybean Oil is determined.
ALTERNATIVES AND COMPARISON OF ESBO EPOXIDIZED SOYBEAN OIL
When choosing an ESBO Epoxidized Soybean Oil alternative, one should not only look at the definition of "plasticizer".
Epoxy functionality, HCl holding capacity, PVC compatibility, migration, viscosity and legislation should be evaluated together.
ESBO EPOXIDIZED SOYBEAN OIL AND EPOXIDIZED LINSEED OIL
Epoxidized flaxseed oil is another epoxidized vegetable oil.
Flaxseed oil initially contains higher unsaturation.
Therefore, it can achieve higher epoxide functionality after proper epoxidization.
Epoxidized flaxseed oil may show stronger stabilizer or reactive character in some systems.
ESBO Epoxidized Soybean Oil is a very common commercial product in the PVC industry worldwide.
No two products have the same CAS number.
It should not be replaced one-to-one with the same usage rate.
ESBO EPOXIDIZED SOYBEAN OIL AND DOTP
DOTP is a terephthalate ester plasticizer.
ESBO Epoxidized Soybean Oil is an epoxidized vegetable oil.
DOTP can often be used as the main plasticizer.
ESBO Epoxidized Soybean Oil, on the other hand, is mostly used as a secondary plasticizer and co-stabilizer.
The main task of DOTP is PVC flexibility.
ESBO Epoxidized Soybean Oil also contributes to HCl retention and thermal stabilization.
Therefore, the two products can be complementary rather than competitors in most formulations.
ESBO EPOXIDIZED SOYBEAN OIL AND DINP
DINP is a high molecular weight phthalate plasticizer.
It is common as the main plasticizer in flexible PVC.
ESBO Epoxidized Soybean Oil is a vegetable oil-based epoxidized co-plasticizer.
DINP provides high plasticizing capacity.
ESBO Epoxidized Soybean Oil provides thermal stabilization additives.
In terms of legislation and target market, the conditions of use of the two products are different.
ESBO EPOXIDIZED SOYBEAN OIL AND DOA
DOA is an adipate ester plasticizer.
It is particularly advantageous for its low-temperature flexibility.
ESBO Epoxidized Soybean Oil can also contribute to flexibility, but it is not a one-to-one substitute for DOA's low-temperature plasticizer performance.
The main additional advantage of ESBO Epoxidized Soybean Oil is PVC stabilization thanks to its epoxide groups.
The two products can also be used together.
ESBO EPOXIDIZED SOYBEAN OIL AND TOTM
TOTM is a high molecular weight trimellitate plasticizer.
It can be used in cable and automotive applications where low volatility and high temperature resistance are required.
ESBO Epoxidized Soybean Oil can be added to the TOTM system as an auxiliary stabilizer and secondary plasticizer.
TOTM can act as the main plasticizer.
The HCl retention ability of ESBO Epoxidized Soybean Oil provides different technical value.
It should not be substituted one-to-one.
ESBO EPOXIDIZED SOYBEAN OIL AND EPOXY REACTIVE DILUENTS
ESBO Epoxidized Soybean Oil is biobased oil with epoxide function.
Epoxy reactive diluents, such as C12–C14 Alkyl Glycidyl Ether or 1,4-Butanediol Diglycidyl Ether, are defined chemicals with lower molecular weights.
Standard reactive diluents usually have a much lower viscosity.
ESBO Epoxidized Soybean Oil has a longer and more flexible triglyceride chain.
They do not provide the same effect in epoxy formulations.
It should not be assumed that ESBO Epoxidized Soybean Oil is a one-to-one reactive diluent alternative.
QUALITY CONTROL AND PURCHASING CRITERIA FOR ESBO EPOXIDIZED SOYBEAN OIL

The degree of epoxidization generally increases as oxirane oxygen rises.
A decrease in iodine value indicates a decrease in the remaining unsaturated bonds.
Therefore, high oxirane oxygen, low iodine value together are useful quality indicators for a high degree of epoxidation.
Acid value is also a critical parameter.
Cargill gives an acid value of 0.5 mg KOH/g < for Vikoflex® 7170.
The typical value of Hallstar Plasthall® ESO is 0.28 mg KOH/g.
The Bisley product uses different specification.
This difference shows the importance of the exact purchase grade.
Color is especially important in white or clear PVC products.
A low APHA color value can be advantageous in light color formulations.
In electrical, medical, or food contact applications, additional impurity and migration criteria may be required.
Industrial general purpose ESBO Epoxidized Soybean Oil with the same CAS number and the food contact certified grade should not be evaluated in the same way.
STORAGE AND HANDLING OF ESBO EPOXIDIZED SOYBEAN OIL
Storage: ESBO Epoxidized Soybean Oil should be stored in appropriate packaging that is clean, dry, and tightly closed.
Temperature: The manufacturer's recommended storage temperature should be taken as a basis.
Cold: ESBO Epoxidized Soybean Oil may exhibit turbidity, crystallization, or viscosity increase at low temperature.
This does not always mean chemical degradation.
Homogeneity can be restored by controlled heating and mixing in accordance with the manufacturer's instructions.
Heat: Long-term storage at unnecessarily high temperature should be avoided.
Light: It is recommended to protect it from direct sunlight.
Humidity: Water contamination should be avoided.
Acids: Uncontrolled contact with strong acids can cause the epoxy rings to open.
Bases: Long contact with strong bases should be avoided.
Oxidizers: Must be kept separate from strong oxidizers.
Packing: Drum, IBC or bulk conveying system are available according to the manufacturer.
Contamination: Cross-contamination of PVC additives or food contact grades should be avoided.
FIFO: Batch and shelf-life management should be implemented.
The transport class must be verified from the exact SDS.
Many ESBO Epoxidized Soybean Oil products have a high flash point and low volatility.
However, this feature does not mean that it does not require fire safety.
The LANXESS safety assessment reports a melting/low temperature point of approximately -15 °C, insolubility in water and a flash point of approximately 316 °C for ESBO Epoxidized Soybean Oil.
Flash points of 280 °C and above may occur in other commercial grades.
The exact SDS value should be used due to the test method and grade differences.
ESBO EPOXIDIZED SOYBEAN OIL SAFETY INFORMATION
ESBO Epoxidized Soybean Oil is oily industrial liquid with low volatility.
There is no general harmonized hazard classification for the substance in ECHA's current classification information.
PubChem also cites the general hazard classification from the current ECHA notifications as "Not Classified".
This does not mean that ESBO Epoxidized Soybean Oil does not require any occupational hygiene measures.
Long-term skin contact should be avoided.
Splashing into the eyes should be avoided.
Appropriate work gloves and eye protection should be used.
Spilled ESBO Epoxidized Soybean Oil can create an oily and very slippery floor.
Spills should be controlled with appropriate absorbent material.
It should not be discharged into the sewer uncontrollably.
In the event of high temperature or fire, organic degradation products may form.
Fire extinguishing and ventilation procedures specified in the SDS should be applied.
When working with ESBO Epoxidized Soybean Oil, the "it's made from soybean oil, so it's completely harmless" approach isn't technically correct.
Even if the starting raw material is of food origin, after epoxidation, the product becomes an industrial functional chemical.
Specific uses where food contact is allowed also do not necessarily mean that ESBO Epoxidized Soybean Oil is directly edible.
Food contact safety is assessed based on migration limits and the final plastic material.
WHAT TO CONSIDER WHEN BUYING ESBO EPOXIDIZED SOYBEAN OIL?
When purchasing ESBO Epoxidized Soybean Oil, the target application should be determined first.

The price of ESBO Epoxidized Soybean Oil should not be compared based solely on the kilogram cost.
For example, oxirane oxygen: which is 6.3% and 7.0%
the two products may not provide the same functional performance.
The acid rating can also affect thermal performance.
Color difference may cause wastage in the open PVC product.
Cheap ESBO Epoxidized Soybean Oil without food contact certificate may not be suitable for food seal production.
Therefore, the acquisition cost should be evaluated together with functional performance and regulatory risk.

ESBO EPOXIDIZED SOYBEAN OIL – TECHNICAL SUMMARY
ESBO Epoxidized Soybean Oil, known as Epoxidized Soybean Oil in Turkish, is a biobased functional oil produced by converting unsaturated fatty acid double bonds in soybean oil into epoxide groups.
CAS No is 8013-07-8 and EC/EINECS No is 232-391-0.
ESBO Epoxidized Soybean Oil is not a single molecule pure chemical.
It consists of variable epoxidized triglycerides resulting from the natural fatty acid distribution of soybean oil.
Therefore, it is not correct to define a single precise molecular formula and a single molecular weight.
ESBO Epoxidized Soybean Oil is usually light yellow, clear, viscous liquid. It is insoluble in water.
One of the most important quality parameters is oxirane oxygen.
Approximately 6.5–7.0% oxirane oxygen can be seen in commercial high-quality grades.
As the degree of epoxidation increases, the oxygen of oxirane increases, while the iodine value associated with the remaining double bonds decreases.
For Cargill Vikoflex 7170, an oxirane content of over 6.8%, a viscosity of 320–500 mPa·s, a specific gravity of approximately 0.99, a moisture of <0.1%, an acid value of <0.5 mg KOH/g, and an iodine value of <3 are reported.
Typical values are given for Hallstar PLASTHALL ESO, such as oxirane oxygen of approximately 7.0%, an acid value of 0.28 mg KOH/g, an iodine number of 0.90, a specific gravity of 0.991 and a refractive index of 1.471.
These values refer to the relevant commercial grades and should not be generalized to all ESBO Epoxidized Soybean Oil products.
The main use of ESBO Epoxidized Soybean Oil is PVC.
It can be used as a secondary plasticizer, auxiliary heat stabilizer, and HCl/acid scavenger in PVC formulation.
It can help reduce the autocatalytic acceleration of degradation by reacting with HCl epoxide groups released during PVC thermal degradation.
It can work synergistically with ESBO Epoxidized Soybean Oil Ca/Zn and other suitable main stabilizer systems.
When used in conjunction with the main plasticizers, it contributes to PVC flexibility.
It should not be assumed that ESBO Epoxidized Soybean Oil alone will meet all the main plasticizer needs.
The main applications are flexible and semi-rigid PVC, film, sheet, artificial leather, floor coverings, cable, gasket, plastisol and different PVC products.
Apart from PVC, it can also be used in coating, adhesive, pigment dispersion, ink, lubricant, epoxy/polyurethane modification and chemical intermediate applications.
In the European Union food contact legislation, ESBO Epoxidized Soybean Oil is defined as FCM No 532 and PM/REF 88640.
In the current (EU) No 10/2011 text, the general specific migration limit is 60 mg/kg.
For glass jar PVC seals containing certain baby and young children's foods, the limit is 30 mg/kg.
In the same legislation, the conditions of oxiran <8% and iodine number <6 are included.
In the US FDA database, ESBO Epoxidized Soybean Oil is listed in various indirect food contact use regulations.
These permissions do not mean that ESBO Epoxidized Soybean Oil is a direct foodstuff.
Food contact suitability must be verified through exact ESBO Epoxidized Soybean Oil grade, final plastic formulation and migration tests.
When purchasing ESBO Epoxidized Soybean Oil, oxirane oxygen, iodine value, acid value, moisture, color, viscosity, density, refractive index and legislation documents for the target application should be checked together.
It is recommended that companies planning to supply ESBO Epoxidized Soybean Oil from Ataman Kimya confirm the current product and offer conditions by sharing their end usage area, PVC system, main plasticizer, stabilizer package, minimum oxirane oxygen, maximum iodine and acid value, food contact requirements, packaging and technical document needs.
