POLYGLYCERYL-10 TRISTEARATE.

Valuable CAS 12709-64-7 / SKIN CONDITIONING

Polyglyceryl-10 Tristearate is a versatile ingredient that functions as an emulsifier, ensuring homogeneous product consistency, while also acting as an emollient and skin conditioning agent. It supports skin hydration and strengthens the natural barrier, making it suitable across various skincare formulations.

Summary

Emulsifying Emollient Skin Conditioning Surfactant Cleansing

Science

Mechanism of Action

This ingredient operates primarily as an emulsifier and surfactant, enabling the stable blending of disparate oil and water phases within cosmetic formulations to achieve a uniform texture. On the skin, it delivers conditioning and emollient benefits by forming a subtle, protective film that mitigates transepidermal water loss and enhances skin softness. Additionally, it contributes to reinforcing the skin's inherent barrier function against environmental stressors and serves as a mild cleansing agent, effectively removing impurities without stripping vital lipids.

Stability

Polyglyceryl-10 Tristearate is noted for its high stability and long-lasting nature. Related compounds, such as Polyglyceryl-10 Stearate, demonstrate strong hygroscopic properties, forming cyclopolymerized structures in aqueous systems to lock in moisture. In anhydrous formulations, it can serve as a structuring agent. When incorporating similar polyglyceryl esters, typical use levels are between 1.0% to 5.0%, added to the oil phase, with a melting point around 55°C.
