Diisooctyl Succinate description

Diisooctyl succinate is a transparent liquid emollient that lends a cushiony texture and silky finish to creams and balms. It may be synthetic or plant-derived (Paula’s Choice uses the latter). The plant version is made from corn and castor oils. Along with helping to make heavier cleansing ingredients and oils feel less greasy, diisooctyl succinate also helps disperse sunscreen ingredients and is considered a suitable alternative to siloxanes (a category of silicones) and palm oil. Additionally, diisooctyl succinate is used as a binding agent in cosmetic powders. It is permitted for use in cosmetics in up to a 100% concentration.
