Stearic Acid is a fatty acid found primarily in animal derivatives, but in vegetable fats as well.

It is also used as the base for the manufacture of other fatty acid ingredients which are used as emulsifers, emollients and lubricants, according to CosmeticsInfo.org. It is also used as an ingredient in candles, plastics, dietary supplements, oil pastels, and for softening rubber; it is a frequent ingredient in soaps made from vegetable oil, and is used to harden the product (Wikipedia).

Functions:

Stearic Acid is a fatty acid found primarily in animal derivatives, but in vegetable fats as well. It is used in a variety of cosmetics and personal care products, as a fragrance ingredient, surfactant and emulsifier. It is also used as the base for the manufacture of other fatty acid ingredients which are used as emulsifers, emollients and lubricants, according to CosmeticsInfo.org. It is also used as an ingredient in candles, plastics, dietary supplements, oil pastels, and for softening rubber; it is a frequent ingredient in soaps made from vegetable oil, and is used to harden the product (Wikipedia).

Stearic Acid is FDA and CIR approved.

Safety Measures/Side Effects:

Stearic Acid is considered a low to moderate hazard ingredient by the Cosmetics Database, which notes concerns regarding cancer, and lesser concerns regarding neurotoxicity, organ toxicity and irritation. One or more animal studies showed brain and nervous system effects, respiratory effects and skin irritation at very low doses, and in vitro tests on mammalian cells show positive mutation results (leading to its designation as a potential carcinogen).

However, Stearic Acid is generally considered a safe and mild ingredient when it is concentrations below limits that have been shown to cause irritation.
