STEARIC ACID 40 EO

STEARIC ACID 40 EO

Stearic acid is a saturated fatty acid with an 18-carbon chain. The IUPAC name is octadecanoic acid. It is a waxy solid and its chemical formula is C17H35CO2H. The salts and esters of stearic acid are called stearates. As its ester, stearic acid is one of the most common saturated fatty acids found in nature following palmitic acid. The triglyceride derived from three molecules of stearic acid is called stearin.
Stearic acid 40 eo belongs to the class of organic compounds known as fatty acid esters. These are carboxylic ester derivatives of a fatty acid. It is mainly used as an ingredient in many types of personal care products and cosmetics including shampoos, hair conditioners, and skin lotion. Stearic acid 40 eo is typically used as a pearlizing agent to give your surfactant products (shampoos and body wases for example) a pearl or pearlized look.
Depending on how much is used, it can turn a transparent product into a white product, depending on the other ingredients.

STEARIC ACID 40 EO:
Stearic acid 40 EO is obtained from fats and oils by the saponification of the triglycerides using hot water (about 100 °C). The resulting mixture is then distilled. Commercial stearic acid 40 EO is often a mixture of stearic and palmitic acids, although purified stearic acid is available.
It is white or cream-colored solid which is soluble in ether, chloroform, acetone, methanol, ethanol, iso ethanol, toluene, soybean oil and mineral oil and insoluble in water. Additionally, this chemical should be sealed in the plastic bucket and stored in the cool place.
It is supplied in the form of white to slightly yellowish powder, and can be used as a consistency giving factor for cosmetic and pharmaceutical creams and emulsions as well as for water-free preparations.
The chemical makeup of octadecanoic acid comes from its name, which alludes to the 18 carbons that make up the backbone of the molecule. Like other saturated fats, stearic acid 40 EO is solid at room temperature and floats on water. It appears white and has a mild aroma. Some vendors will sell stearic acid in crystalline or powder form. The structure of stearic acid, which includes both polar and non-polar components, allows it to function in the creation of soap or detergent. The polar end links to water, while the non-polar end surrounds organic dirt or fats. The non-polar end encapsulates these particles, which wash away with rinsing to remove the water.
Though edible, stearic acid has many other uses outside the human body. One of the best-known applications in industries is its use in vulcanizing rubber. However, octadecanoic (stearic) acid does much more than help in the creation of tires and industrial grade rubber. Its uses extend to several other industries, aided by stearic acid's softening abilities, inherent lubricity and non-toxic nature.
Stearic acid is more abundant in animal fat (up to 30%) than in vegetable fat (typically <5%). The important exceptions are the foods cocoa butter (34%) and shea butter, where the stearic acid content (as a triglyceride) is 28–45%. Commercially, fats high in oleic acid such as palm and soy may be hydrogenated to convert oleic into stearic acid.
In terms of its biosynthesis, stearic acid 40 EO is produced from carbohydrates via the fatty acid synthesis machinery wherein acetyl-CoA contributes two-carbon building blocks.
In general, the applications of stearic acid 40 EO exploit its bifunctional character, with a polar head group that can be attached to metal cations and a nonpolar chain that confers solubility in organic solvents. The combination leads to uses as a surfactant and softening agent. Stearic acid 40 EO undergoes the typical reactions of saturated carboxylic acids, a notable one being reduction to stearyl alcohol, and esterification with a range of alcohols. This is used in a large range of manufactures, from simple to complex electronic devices. Stearic acid (E number E570) is found in some foods.
Stearic acid 40 EO is mainly used in the production of detergents, soaps, and cosmetics such as shampoos and shaving cream products. Soaps are not made directly from stearic acid 40 EO, but indirectly by saponification of triglycerides consisting of stearic acid esters. Esters of stearic acid with ethylene glycol, glycol stearate, and glycol distearate are used to produce a pearly effect in shampoos, soaps, and other cosmetic products. They are added to the product in molten form and allowed to crystallize under controlled conditions. Detergents are obtained from amides and quaternary alkylammonium derivatives of stearic acid.
Stearic acid, a waxlike fatty acid also known as octadecanoic acid, is an important component of stratum corneum lipids. Stearic acid is also found in cocoa butter, shea butter, and other vegetable fats, as well as animal tallow. As an FDA-approved ingredient in several cosmetic products, it is used as a surfactant and emulsifying agent for fragrance and as the base for other fatty acid ingredients that are synthesized into emollients and lubricants. Stearic acid 40 EO is used most often to thicken and retain the shape of soaps (indirectly, through saponification of triglycerides composed of stearic acid esters), and it is also used in shampoos, shaving creams, and detergents.
Fatty acid ethoxylate are produced by the process of ethoxylation on fatty Acids like Coconut Fatty Acid, Lauric Acid, Oleic Acid and Stearic Acid. These are non-ionic surface-active agents manufactured by addition of ethylene oxide to fatty acids producing a range of ethoxylates having different moles of EO. A surface-active agent of surfactant refers to a chemical which when dissolved in another solvent aligns itself at the boundary of liquid and the stain molecules to alter the characteristics of the interface. In this context, surfactants have gained widespread usage as cleaning and emulsifying agents in household and industrial applications.
Fatty acid ethoxylate, range from clear liquid, pasty or waxy solids. This nature depends on the length of alkyl chain and the apparent number of ethoxyl groups. Non-ionic surfactants contain both hydrophobic tail portion and hydrophilic polar head groups. Thus, tend to dissolve in both aqueous and oil phase reducing the surface tension of liquids. The use of hydrophilic groups like EO brings about better solubility in water since more hydrogen bonding can exist. These Fatty acid ethoxylate do not dissociate in solution i.e. non-ionic in solution thus do not form charged particles with residual electrical charge. This means that these non-ionic Fatty acid ethoxylate surfactants will work well in hard water and also at low temperatures. Moreover, they exhibit more stability in acidic and alkali solution plus miscibility with other surfactants. Further, since these Fatty acid ethoxylate are nonionic surfactants they exhibit excellent foam properties, outstanding solvency and absolute chemical stability providing good detergency properties. Fatty Acid Ethoxylates are primarily used as non-ionic surfactants in a number of processes in the industrial and domestic boundaries. Since these fatty acid ethoxylate are having different HLB based on their moles of EO they can function as solubilizers, dispersing agents, emulsifiers, fabric softeners, antistatic additives, lubricants, and viscosity regulators in textiles, metal working fluids and leather processing. These Nonionic fatty acid ethoxylate surfactant products are friendly on the dermis even at greater loadings and exposure. Additionally due to their low toxicity and natural base, they find use in cosmetic and pharmaceutical formulations. With reference to their ability to foam and low comparative cost, polyoxyethylene (fatty acid ester) have been the most attractive non-ionic detergent product in the market. When combined with different types of builders, these surface-active agents are ingredients for a majority of domestic and industrial cleaning applications. Fatty acid ethoxylates are also applied as cleansing agents, dispersants (emulsifiers), wetting agents water softeners and spin dying agents in textile Industries. However, they are also used as dispersants and solubilizes in cosmetics and health care industrial applications. Fatty acid ethoxylate includes; stearic acid ethoxylates, lauric acid ethoxylates and coco fatty acid ethoxylate. These products are used in textile and in the manufacture of spin finishes.
Use & Benefits: 
It contains both oil-loving and water-loving groups in its chemical structure just like other monoesters of glycerin. So, it can be used as an emulsion stabilizer. When the solid content in the formulation is lesser, it works the best since it also increases viscosity significantly. It makes the formulation more appealing as it’s a “Pearlizing agent”. It has stearic acid which is a fatty acid thus it also moisturizes the skin and forms a layer on the skin in such a manner that the moisture does not evaporate and let the skin retain the moisture, so it can also be called a skin conditioning agent. It can be used widely in cosmetics along with other excipients staring from lotions, creams, and gels to perfumes and fragrances.
Lubricants, softening and release agents
In view of the soft texture of the sodium salt, which is the main component of soap, other salts are also useful for their lubricating properties. Lithium stearate is an important component of grease. The stearate salts of zinc, calcium, cadmium, and lead are used to soften PVC. Stearic acid 40 EO is used along with castor oil for preparing softeners in textile sizing. They are heated and mixed with caustic potash or caustic soda. Related salts are also commonly used as release agents, e.g. in the production of automobile tires. As an example, it can be used to make castings from a plaster piece mold or waste mold, and to make a mold from a shellacked clay original. In this use, powdered stearic acid 40 EO is mixed in water and the suspension is brushed onto the surface to be parted after casting. This reacts with the calcium in the plaster to form a thin layer of calcium stearate, which functions as a release agent
When reacted with zinc it forms zinc stearate, which is used as a lubricant for playing cards (fanning powder) to ensure a smooth motion when fanning. Stearic acid EO is a common lubricant during injection molding and pressing of ceramic powders. It is also used as a mold release for foam latex that is baked in stone molds.
Being inexpensive, nontoxic, and fairly inert, stearic acid 40 EO finds many niche applications. Stearic acid 40 EO is used as a negative plate additive in the manufacture of lead-acid batteries. It is added at the rate of 0.6 g per kg of the oxide while preparing the paste. It is believed to enhance the hydrophobicity of the negative plate, particularly during dry-charging process. It also reduces the extension of oxidation of the freshly formed lead (negative active material) when the plates are kept for drying in the open atmosphere after the process of tank formation. As a consequence, the charging time of a dry uncharged battery during initial filling and charging (IFC) is comparatively lower, as compared to a battery assembled with plates which do not contain stearic acid additive. Fatty acids are classic components of candle-making. Stearic acid 40 EO is used along with simple sugar or corn syrup as a hardener in candies. In fireworks, stearic acid 40 EO is often used to coat metal powders such as aluminium and iron. This prevents oxidation, allowing compositions to be stored for a longer period of time.
An isotope labeling study in humans concluded that the fraction of dietary stearic acid 40 EO that oxidatively desaturates to oleic acid is 2.4 times higher than the fraction of palmitic acid analogously converted to palmitoleic acid. Also, stearic acid 40 EO is less likely to be incorporated into cholesterol esters. In epidemiologic and clinical studies, stearic acid was found to be associated with lowered LDL cholesterol in comparison with other saturated fatty acids.
APPLICATIONS OF STEARIC ACID 40 EO
Stearic acid's attributes of activating and lubricating allow this fatty acid to play a key role in several sectors. Its most frequent industrial use is for the creation of rubber. Without this or similar fatty acids, modern vulcanization methods would look quite different.
They are used as emulsifiers, solubilisers, dispersing agents, viscosity regulators, fabric softeners and antistatic additives, as well as for coating of glass fibres and also as softeners and plasticising agents in coatings and plastics.
They are also used in textile and leather auxiliaries, in the metal working, lubricant and plastics industries, in crop protection formulations and many other applications. Because of their good toxicological profile, fatty-acid polyglycol ethers are also suitable for cosmetic and pharmaceutical applications.
Activator or accelerator
Activators and accelerators do different things chemically. Stearic acid 40 EO appears as an activator triggering the reactions of the accelerators. Understanding the differences helps to know why both components are crucial to success for certain processes.
An accelerator is a chemical added to a process to speed the reaction. Accelerators are critical in industrial applications during which waiting for sluggish reactions wastes time and money. The type of accelerator used depends on the reaction that requires hastening. Sometimes, chemists use multiple accelerators for the best results.
Activators start a process, whether that process uses accelerators or not. Stearic acid 40 EO acts as an activator for catalyzing process chemicals. Often, stearic acid 40 EO reacts with zinc oxide to serve as an activator, while having secondary lubricating properties as a functional metallic stearate.
When activators work in conjunction with accelerators, chemical processes occur more predictably and quickly.
Internal lubricant:
Internal lubricants enable molecules to move easier between each other. When this happens, the product flows easier due to lower viscosity. Fatty acids, with their polar and non-polar components, function as internal lubricants due to their differing polar parts.
With polar polymers, a fatty acid coats fillers and aids in the movement of stabilizers in the polymer. By these means, fatty acids can make products they are part of disperse and flow more smoothly by reducing the viscosity.
Mold release agent and surface lubricant
Just as stearic acid 40 EO improves flow and viscosity as an internal lubricant, it also acts as an external lubricant.
Lubrication occurs when a substance, usually fat or oil, coats a pair of surfaces, allowing them to move smoothly over one another. As a fatty acid, stearic acid 40 EO can function as a topical lubricant for metals, though it requires a high number of layers to remain active through multiple uses and not wear off.
Though this particular single use as an external lubricant proves useful in some situations, stearic acid 40 EO can also be a dual-purpose agent in facilitating movement. If a polymer already has a plasticizer added, fatty acids in the mixture become external lubricants. To ensure proper use as a surface treatment for aiding in releasing products from molds, engineers add stearic acid to a polymer in higher amounts, compared to when it only has a use as an internal lubricant.

Usages:
Soaps, Shaving Creams and Detergents
Stearic acid 40 EO is used to harden and thicken products like bars of soap and candles. The presence of stearic acid 40 EO in soap helps to create a lather when mixed with water, providing a velvety feeling; it is this property that also makes it a must-have ingredient in most shaving foams and creams as well. When the soap formula is hardened into a solid, it helps to do away with the watered-down, runny feeling. This is brought about by the surfactant action that brings down the surface tension of a given oil; when the surface tension is reduced, oil and water can be mixed much better, and do not split into layers of oil and water.
Stearic acid 40 EO has occlusive properties which means that it ensures hydration for the skin through the prevention or delaying of loss of moisture from the surface of your skin. When you are using a product that contains stearic acid 40 EO, you don’t have to shake it vigorously before you use it; the presence of stearic acid 40 EO in a product helps to extend not only its effectiveness, but also its shelf life. It is the stearic acid 40 EO that works to dislodge the grime, sweat and extra oil from your hair and skin when you apply shampoo, soap, face wash or body wash.
Any cleansing product that contains stearic acid 40 EO is endowed with conditioning features in addition to the cleansing ability; add that to the preservative traits, it helps to increase the effectiveness and shelf life of the final product in which it is used. In shampoos, the stearic acid content helps to soften the hair and render it glossy and light.
Lotions, Moisturizers, and Face Creams:
In cosmetics and personal care products, stearic acid 40 eo is widely used and can be found in lotions, creams, powders, skin cleansing products, makeup bases and foundations, mascara, eye shadow, eyeliner, hair conditioners and rinses, and suntan and sunscreen products.
The use of stearic acid 40 EO in lotions and creams is essential as it helps to add thickness to the product, and gives it a rich, lustrous finish. It also leaves a smooth, velvety feel on the skin when the product is applied. If you carefully check the labels of face creams and moisturizers, you will be able to read that it contains stearic acid.
Why is it used in cosmetics and personal care products?
Stearic acid 40 eo acts as a lubricant on the skin's surface, which gives the skin a soft and smooth appearance. It also slows the loss of water from the skin by forming a barrier on the skin's surface. It  helps to form emulsions by reducing the surface tension of the substances to be emulsified.
Candles 
We have already seen that stearic acid 40 EO resembles wax, and that when added to products, it helps to harden and solidify them. This makes them ideal for addition to paraffin candles. The advantage is that a hard candle lasts longer, because fire will take a much longer time to melt a hard candle as compared to a soft one. As the wax cools down, stearic acid shrinks it, allowing it to be released easily from a mold. With so many people taking up candle making as a home industry, there are many fancy shapes of candles being made, and these are all made in molds. With complicated mold shapes, it can become difficult to pry out candles – but the slight shrinkage brought about by stearic acid makes the process easy.
Available for the manufacture of cosmetics, plastic cold plasticisers, release agents, surfactants, accelerators of rubber vulcanization, polishing agents, metal soap, floaters of metal minerals, softeners and other organic chemical agents.
The fat cells present in stearic acid 40 EO attach themselves to the cells of the fragrance added to the candle. This helps the fragrance to last longer as the aroma as it prevents the aroma from gushing out of the candle in one go. Candles contain about 3 to 5% stearic acid.
Casts and Molds
As it is a gentle chemical, the uses of stearic acid 40 EO can be found in industrial applications as well. It is often used to make castings and molds; the castings are usually made from a piece of plaster, or broken/waste mold; shellacked clay is used to make a mold using stearic acid. Here, stearic acid is powdered and mixed in water; this mixture is then applied to the surface that will be separated once the casting is over. This solution has a chemical reaction with the calcium present in the plaster, and forms calcium stearate; this chemical helps to release the cast easily and quickly. Stearic acid is commonly used as a lubricant in the process of injection molding and pressing of ceramic powders, and to release mold for foam latex when it has been baked in molds made of stone.
Rubber
The stearic acid 40 EO of rubber grade that we offer comes from well-known organisations. This rubber grade stearic acid is used in the processing of the rubber compound as a dispersing agent, plasticizer and lubricant.
Paints & Coatings
Stearic acid 40 EO is used directly in some paints in the paint sector, for example in cement paints and that is indirectly in different formulations of the coating such as zinc stearates, additives, etc.
Plastics
Stearic acid 40 EO, as a good gravity and light and heat stability, is commonly employed for PVC pipe, platform, profile, film manufacturing, heat stabilizer manufacturers.PVC plastic tube, stearic acid 40 EO, is an efficient method for adding a heat stabilizer to the processing of the “coke” in a PVC film and can cause sulfide-finished film de-colouration due to a protection storm. Stearic acid is applied in plastics as a lubricant and reduction of friction.
Playing Cards
When stearic acid 40 EO reacts with zinc, zinc stearate is formed; this is used as ‘fanning powder’, which helps lubricate playing cards, and helps in smooth shuffling, fanning and so on, of the cards.
Batteries
In the making of lead-acid batteries, stearic acid 40 EO is used as a negative plate additive, as it helps to improve the plate’s hydrophobicity, especially when the battery has to be dry-charged. The stearic acid 40 EO helps to reduce the oxidation extension of the negative active material, or the lead which forms afresh when the plates are left to dry in the open after the tank formation process is completed. This helps to reduce the time required for charging a dry battery for the first time considerably, when compared to a battery that does not feature added stearic acid in its plates.
Fireworks
Stearic acid 40 EO is also often used in fireworks for coating aluminum, iron, and other metal powders. This helps to prevent or delay the onset of oxidation, and extend the shelf life of the compositions. You can store them for longer periods of time.
Contraindications
Stearic acid is generally not meant to be consumed, and is for exclusive external use. If consumed, it can cause chemical pneumonitis. People with especially sensitive respiratory systems, high vulnerability to allergies, pregnant and nursing mothers, and so on, should take special care if they have to handle stearic acid in the raw form, and are advised to seek medical consultation beforehand. Raw stearic acid should not be left in places easily accessible to children under the age of 8. Chemical suppliers in India will give you all the information regarding safe handling of the material when you purchase the raw material.
Stearic acid in its raw form can cause the skin to itch, sting, or break out in hives, rashes, blisters, and become red and scaly.
