Science
Mechanism of Action
This ingredient functions primarily as an emollient and occlusive agent, forming a semi-permeable film on the skin's surface. This barrier effectively minimizes transepidermal water loss (TEWL), thereby increasing epidermal hydration and suppleness. Furthermore, its plant-derived composition provides antioxidants such as sinapinic acid and vitamin E, alongside omega-9 erucic acid, which collectively support the skin's defense against environmental stressors and contribute to surface repair. In formulations, it also serves as an emulsifier and viscosity-controlling agent.

Stability
For optimal thermal stability in oil gels, co-formulation with silica, waxes, or butters is advised. Processing typically involves melting above 60°C, followed by moderate stirring during cooling until cloudiness appears, and a brief homogenization step at approximately 35°C. It is also effective in stabilizing water-in-oil (W/O) emulsions.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel deemed the closely related "Hydrogenated Rapeseed Oil" as safe for cosmetic applications. This ingredient itself is recognized as non-toxic by major regulatory bodies like the FDA and EU Cosmetics Regulation, and is generally well-tolerated, including by sensitive skin types. Its compliance with FDA food-use criteria for fully hydrogenated rapeseed oil further supports its safety profile.
