Science
Mechanism of Action
This ingredient operates as an effective emollient, forming an occlusive layer on the skin's surface to minimize transepidermal water loss, thereby enhancing moisture retention. Furthermore, its ricinoleic acid derivative component imparts humectant properties, drawing moisture into the stratum corneum. Beyond skin benefits, it significantly contributes to cosmetic formulations by acting as a consistency-building and viscosity-controlling agent.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has assessed Hydrogenated Castor Oil (the parent compound) as safe for use in cosmetics. The FDA also categorizes hydrogenated castor oil as an indirect food additive. While a specific CIR assessment for Hydrogenated Castor Oil Triisostearate was not identified, its safety profile is broadly inferred from its well-regarded parent compound and similar derivatives, which are considered relatively nontoxic and nonirritant.
