This prolongs how long products like lotions, cosmetics, conditioners, etc. Many fat-containing foods, both plants and those that come from animals, contain saturated fatty acids — including stearic, lauric , myristic, oleic and palmitic acids.
Animal fats are higher in stearic acid than most plants that contain oils. The exceptions to this rule are cocoa butter and shea butter, two plant-derived products that are both relatively concentrated sources of SA. SA is also found in supplements, including magnesium stearate, which is usually derived from palm oil.
Because of its waxy texture, SA acts as an emulsifier of ingredients used in supplements and as a lubricant to fill capsules when dry powdered ingredients are used. You can use SA at home to make your own lotions and soaps.
Most recipes will call for water, oils and an emulsifier such as SA to create a stable and smooth product. Purified stearic acid is available but less commonly sold. The more you use, the thicker your product will be. Emulsifiers will bind together water and oil to create lotion that will not separate. Below is a basic homemade lotion recipe provided by the Soap Queen website:. The U. 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. The stearic acid 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. Stearic acid 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.
Stearic acid, as a good gravity and light and heat stability, is commonly employed for PVC pipe, platform, profile, film manufacturing, heat stabilizer manufacturers.
Stearic acid is applied in plastics as a lubricant and reduction of friction. The stearic acid 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. Stearic acid 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. 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. 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 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. There is limited evidence for the potential of exogenously produced stearic acid to play a significant role as a topical dermatologic therapeutic agent. Stearic acid is thought to be associated with behenyltrimethylammonium chloride through salt bridges, and the combination is believed to have the capacity to build bilayer vesicles with the aid of hinokitiol beta-thujaplicin , a natural monoterpenoid found in the wood of trees in the Cupressaceae family that has been shown to exert topical inhibitory activity against Chlamydia trachomatis Antimicrob.
Agents Chemother. These vesicles, used to enhance the skin permeation of hinokitiol, were tested in hairless mice and appear to have the potential to promote hair growth Drug Dev. Create Account. Puracy Blog. Stearic Acid What is stearic acid?
