Isostearic Acid

Isostearic acid is a lightly-branched, liquid fatty acid produced by the reaction of oleic acid with a natural mineral catalyst – there is no chemical addition in this reaction, isostearic acid is based 100% on the parent oil or fat. Isostearic acid is used in applications which require a liquid fatty acid with exceptional stability: thermal stability in the case of a lubricant, odour stability for a cosmetic formulation, and oxidation stability for products with long shelf-life requirements. The branching structure of isostearic acid also enhances its dispersing power, and it is used in cosmetic and industrial applications for the stabilisation of pigments and mineral particles in oils and solvents.
