Brassica Campestris (Rapeseed) Sterol
What is Brassica Campestris (Rapeseed) Sterol?
Brassica Campestris (Rapeseed) Sterol consists of phytosterols derived from the unsaponifiable fraction of rapeseed oil, extracted from seeds of the Brassica campestris plant, a cruciferous crop valued for its lipid-rich oil. Chemically, these are triterpenoid alcohols like beta-sitosterol, campesterol, and brassicasterol, mirroring human skin ceramides and cholesterol. In cosmetic products such as moisturizers, serums, and balms, they serve primarily as emollients and skin conditioners. They work by integrating into the stratum corneum, promoting a smooth occlusive layer that limits moisture evaporation while improving texture and spread. Their lipophilic nature aids emulsion stability, making them ideal for oil-in-water formulations. As a renewable, vegetable-sourced ingredient, they provide a biocompatible option for enhancing skin feel without heavy greasiness.
