What it is
Octyldodecyl stearoyl stearate is a heavy emollient ester formed from octyldodecanol and a stearic-acid-derived stearate. It imparts a rich, smoothing, cushiony slip to creams, sticks, and color cosmetics and helps condition the skin surface. In sun sticks and balms it contributes body and a velvety after-feel.
Safety & warnings
This ester is generally well tolerated and is not a known fragrance allergen. Because it is a rich, occlusive emollient, it may feel heavy and could be less suitable for very oily or breakout-prone skin.
Origin & sourcing
Synthetic. It is manufactured by esterification of the fatty alcohol octyldodecanol with stearic-acid-based components; the fatty raw materials are commonly derived from plant or other natural oils.
