POLYGLYCERYL-6 OCTASTEARATE.

Valuable / SURFACTANT - EMULSIFYING

Polyglyceryl-6 Octastearate is a versatile polyglyceryl ester highly valued for its primary role as an emulsifier, enabling the creation of stable cosmetic formulations by seamlessly blending oil and water. Additionally, it acts as a skin-conditioning agent, imparting a soft, moisturized feel to the skin.

Science

Mechanism of Action

This ingredient functions principally as an emulsifier, significantly stabilizing oil-in-water and water-in-oil emulsions by forming a film and reducing surface tension. On the skin, it contributes to hydration and softness, enhancing the product's texture and spreadability. It may also facilitate the deeper penetration of other active substances, diminish the sensation of oiliness, and offer a protective skin barrier while preventing crystallization in formulations.
