Science
Mechanism of Action
PENTAERYTHRITYL STEARATE/ISOSTEARATE/ADIPATE/HYDROXYSTEARATE works by creating an occlusive barrier on the skin's surface, effectively preventing transepidermal water loss to maintain hydration and elasticity. As a plant-derived ester, its composition closely resembles natural sebum, granting it exceptional compatibility with the skin's intrinsic barrier. This dual action results in notably softer, more hydrated skin while providing a silky sensory feel and protection against environmental factors. Beyond skin benefits, it functions as a potent viscosity regulator, stabilizing cosmetic formulations to achieve a uniform and spreadable product consistency.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel deemed this class of pentaerythrityl tetraester compounds safe for use within current cosmetic practices. Evaluations indicate it is non-irritating and non-sensitizing to human skin. Formulators should, however, acknowledge its potential to facilitate the absorption of other ingredients.
