Is Isostearic Acid vegetarian?

Isostearic acid, also known as isooctadecanoic acid, is a branched-chain C18 fatty acid used as an emollient and emulsifying agent in cosmetics. It is typically manufactured synthetically from oleic acid, which may be sourced from plant oils (e.g. tall oil, sunflower) or, less commonly, from animal tallow.

An ingredient is considered vegetarian if it avoids components derived from killing an animal.
