Summary

Emollient Skin Conditioning Occlusive Agent Viscosity Increasing (Non-aqueous) Emulsifier

Science

Mechanism of Action

This multi-functional ingredient acts primarily as an emollient and occlusive agent, forming a non-greasy, protective film on the skin's surface to effectively minimize transepidermal water loss and lock in essential moisture. Beyond its direct hydrating benefits, it significantly improves the sensory profile of formulations by enhancing spreadability and absorption, contributing to a silky-smooth feel. Furthermore, it functions as a non-aqueous viscosity increasing agent for formula stability and can serve as an emulsifier, ensuring the consistent homogeneity of oil and water phases within a product.
