What is it?
Isostearic acid is a branched-chain fatty acid used in skincare as an emollient, emulsifier, and texturing agent. Its unique structure gives it excellent stability and skin compatibility, making it a valuable ingredient in skincare formulations.
Where does it come from?
Isostearic acid is naturally sourced from plant-based oils, such as rapeseed oil, and modified into a branched form. This contributes to its spreadability and resistance to oxidation, while still deriving from natural sources.
