DESCRIPTION

The current product portal identifies CAS Number 61791-12-6 for Agnique CSO 25.
The product is chemically described as ethoxylated castor oil with an average of approximately 25 EO units.
Agnique CSO 25 is supplied as a nonionic emulsifier, wetting aid, solubilizer, and agricultural formulation auxiliary.

Structurally, Agnique CSO 25 is based on the triglyceride framework naturally present in castor oil.
Castor oil consists predominantly of ricinoleate-derived fatty chains containing internal hydroxyl functionality.
Ethoxylation adds polyoxyethylene chains to available hydroxyl sites and produces a distribution of related molecular species.
This distribution means Agnique CSO 25 is a UVCB substance rather than one chemically uniform molecule.

The generalized structure of ethoxylated castor oil can be represented as C₅₇H₁₀₄O₉(CH₂CH₂O)n.
For Agnique CSO 25, n represents an average ethoxylation level near 25 rather than an identical value in every molecule.
Individual molecules may contain different numbers and distributions of oxyethylene groups.
One exact molecular formula and molecular weight are therefore not appropriate for the complete commercial product.

Agnique CSO 25 contains hydrophobic fatty chains and hydrophilic polyoxyethylene regions within the same molecular population.
The castor-oil-derived regions associate with oils, waxes, solvents, and hydrophobic active ingredients.
The oxyethylene regions interact with water and polar ingredients through dipolar and hydrogen-bonding interactions.
This amphiphilic balance enables accumulation at interfaces and supports emulsion formation.

Agnique CSO 25 is classified as a nonionic surfactant because its principal hydrophilic groups do not carry a permanent electrical charge.
Its nonionic nature generally provides useful compatibility with many ionic and nonionic formulation ingredients.
Performance can nevertheless change with temperature, electrolytes, water hardness, solvent composition, active ingredients, and surfactant concentration.
The complete formulation must therefore be evaluated rather than selecting Agnique CSO 25 solely from its surfactant class.

Agnique CSO 25 is manufactured through controlled reaction of castor oil with ethylene oxide.
Industrial ethoxylation requires catalyst selection, controlled temperature and pressure, and management of residual ethylene oxide.
The average degree of ethoxylation is adjusted to obtain the required balance between oil affinity and water compatibility.
Finishing and purification operations control water, catalyst residues, color, odor, acidity, and physical consistency.

At room temperature, Agnique CSO 25 is described as a colorless to yellow, opaque or slightly cloudy liquid.
The product may separate or form sediment during cold storage without necessarily undergoing chemical deterioration.
Agnique CSO 25 becomes a clear liquid at approximately 40°C according to the archived Technical Information.
Separated or partially solidified material should be homogenized before processing.

Agnique CSO 25 is reported as a yellowish liquid at 23°C with an approximate active concentration of 100%.
The archived data report a density of approximately 1.07 g/cm³ at 20°C.
The reported density decreases to approximately 1.05 g/cm³ at 50°C.
These values are typical technical data rather than guaranteed batch-release specifications.

Agnique CSO 25 has a representative Brookfield viscosity of approximately 110 mPa·s at 60°C.
Its viscosity is expected to increase substantially as temperature decreases.
Cold material may therefore become difficult to pump or pour even before complete congealing occurs.
Processing equipment should be selected according to the product’s temperature-dependent flow behavior.

Agnique CSO 25 has an approximate congealing point of 5°C.
The archived Technical Information separately reports an approximate pour point of −1°C.
These values describe different physical test responses and are not necessarily contradictory.
Cold-storage behavior should be evaluated through the supplier’s specified handling and reconstitution procedure.

Agnique CSO 25 has a representative cloud point of approximately 72°C under EN 1890 Method E conditions.
The cloud point describes the temperature at which hydration of the nonionic polyoxyethylene groups decreases sufficiently to produce visible phase separation.
Cloud-point behavior depends strongly on concentration, electrolytes, solvents, and the selected test method.
A cloud point measured under one standardized system should not be treated as the phase-separation temperature of every finished formulation.

Agnique CSO 25 has a representative surface tension of approximately 40 mN/m at 1 g/L in distilled water at 23°C.
This reduction from the surface tension of pure water supports wetting and spreading behavior.
Other active ingredients, salts, solvents, co-surfactants, and water quality can substantially alter the observed value.
Finished-product surface tension should therefore be measured directly under intended dilution conditions.

Agnique CSO 25 has a representative saponification number of approximately 50 mg KOH/g.
The product has a reported pH near 6 when measured.
The measured pH can decrease during storage without necessarily affecting technical performance.
The reported iodine color is approximately 3 when tested at 70°C.

Agnique CSO 25 is highly concentrated and has a maximum representative water content of 0.3%.
The product is hygroscopic and can absorb moisture rapidly when containers remain open.
Repeated atmospheric exposure can therefore alter water content, clarity, analytical results, and formulation behavior.
Drums should be tightly resealed after every opening.

A 10% Agnique CSO 25 solution is reported to form a clear solution in distilled water at 23°C.
The same concentration is reported to remain clear in potable water containing approximately 2.9 mmol/L calcium ions.
Agnique CSO 25 also forms clear solutions in alcohols and aromatic hydrocarbons under the referenced screening conditions.
Water compatibility reflects its higher ethoxylation level relative to less hydrophilic castor-oil ethoxylates.

Agnique CSO 25 is reported as insoluble or phase-separating in 5% sodium hydroxide solution.
The product is also reported as incompatible with petroleum oils under the referenced 10% solubility test.
Agnique CSO 25 forms an opaque but homogeneous emulsion in a 5% salt solution.
Solubility results can change with concentration, temperature, oil composition, and the presence of co-surfactants.

Agnique CSO 25 is reported to form a clear solution in 5% hydrochloric acid under the referenced test conditions.
This result should not be interpreted as proof of unlimited stability in strongly acidic formulations.
Prolonged exposure to severe acidity, alkalinity, oxidation, or heat may degrade ester or polyether structures.
Chemical stability must be assessed at the actual concentration, temperature, and storage duration of the finished product.

Agnique CSO 25 has an approximate flash point of 290°C according to ISO 2592 in the Technical Information.
The high flash point reflects its comparatively high molecular mass and very low ambient volatility.
Agnique CSO 25 remains an organic combustible material despite not behaving like a rapidly evaporating solvent.
Severe heating or fire can generate carbon monoxide, carbon dioxide, aldehydes, and irritating organic decomposition products.

Agnique CSO 25 does not have one sharply defined boiling point because it contains a distribution of high-molecular-weight ethoxylated species.
Its vapor pressure is expected to be low under ordinary storage and processing temperatures.
Aerosol or mist exposure may nevertheless occur during spraying, high-speed mixing, or transfer.
Local exhaust ventilation is appropriate where airborne droplets can be generated.

Agnique CSO 25 may produce foam during dilution, pumping, recirculation, or high-shear mixing.
Foam behavior depends on concentration, temperature, water hardness, mechanical energy, and other surfactants.
Excessive foam can interfere with tank filling, volume measurement, milling, and manufacturing throughput.
Antifoam agents must be screened carefully because they can also affect emulsion stability and wetting.

Agnique CSO 25 can be combined with compatible anionic, nonionic, and selected amphoteric surfactants.
Appropriate combinations may improve spontaneous emulsification, hard-water tolerance, droplet-size distribution, and temperature stability.
Incompatible blends may produce phase separation, precipitation, excessive viscosity, clouding, or uncontrolled foam.
Systematic formulation testing should therefore compare several surfactant ratios.

Agnique CSO 25 is derived partly from natural castor-oil feedstock and is described as biodegradable.
Its hydrophobic portion is bio-based, while the ethylene oxide used to create the polyoxyethylene chains may be conventionally petrochemical unless otherwise specified.
Agnique CSO 25 should therefore be described as partially bio-based rather than assumed to be entirely renewable.
Environmental performance should be evaluated using current supplier and regulatory documentation.

Agnique CSO 25 should be stored indoors in a dry area that is not overheated.
The material may absorb moisture rapidly, making tightly resealed containers essential.
The Technical Information states that properly stored unopened material has a shelf life of at least two years in its original packaging.
Current storage-life confirmation should be obtained.

Separated or solidified Agnique CSO 25 may be heated gently to approximately 50–70°C and homogenized before use.
The temperature should not exceed 70°C during reconstitution.
Internal electrical heating elements should be avoided because they can create localized overheating.
Heating cabinets or controlled external heating systems provide more uniform temperature distribution.

Heated storage tanks containing Agnique CSO 25 should be blanketed with nitrogen when operated at approximately 50–70°C.
Nitrogen blanketing limits prolonged contact with air and helps reduce oxidative discoloration.
Constant gentle stirring can reduce local overheating and maintain product homogeneity.
Storage procedures must prevent unnecessary exposure to oxygen, moisture, and excessive temperature.

Agnique CSO 25 is compatible with several stainless-steel grades identified.
Examples include AISI 321, AISI 316 Ti, and low-carbon stainless-steel grades listed by the producer.
Seal, hose, gasket, pump, and coating compatibility must still be verified separately.
Equipment selection should consider temperature, cleaning chemicals, and the complete formulation rather than the surfactant alone.
