Superior Organic Compatibility:?The long octadecyl chain integrates seamlessly with organic oils, esters, and waxes, improving the stability and feel of emulsions and anhydrous systems.
Enhanced Sensory Profile:?Imparts a unique, cushioned, and velvety feel to the skin. It reduces the greasiness of heavy formulations and provides a smooth, powdery after-feel.
Excellent Water Repellency:?Forms a durable, non-occlusive, and breathable film that provides excellent water and wear resistance, making it ideal for sunscreens and long-wear cosmetics.
Improved Pigment & Active Dispersion:?Acts as an effective dispersant for pigments in color cosmetics and inorganic UV filters (like Titanium Dioxide and Zinc Oxide) in sun care products, leading to more uniform coverage and enhanced efficacy.
Superior Lubricity & Slip:?Provides excellent slip for easy application in skincare and makeup. In hair care, it offers superb conditioning and detangling without heavy buildup.
Long-Lasting Performance:?The robust film-forming properties contribute to long-wear characteristics in foundations, lipsticks, and protective creams.
