POLYGLYCERYL-4 OLEYL ETHER.

Essential CAS 71032-90-1 / 9022-76-8 / 112708-25-5 / SURFACTANT - EMULSIFYING

This polyglyceryl derivative serves as a highly effective emulsifier, expertly blending immiscible oil and water phases to create stable, homogeneous product textures. Beyond its primary function, it enriches formulations with significant emollient and conditioning properties, enhancing skin hydration and smoothness.

emulsifying skin conditioning surfactant emollient

Science

Mechanism of Action

Polyglyceryl-4 Oleyl Ether functions primarily as a surfactant and emulsifier by reducing the surface tension between oil and water, enabling the formation of stable, uniform emulsions. It is particularly effective as an oil-in-water emulsifier, capable of stabilizing challenging formulations. On the skin, it delivers rich emollient and nourishing benefits, improving hydration and leaving the skin feeling soft and smooth by forming a protective barrier. This contributes to excellent conditioning and may help reduce the appearance of fine lines by promoting skin elasticity and hydration.
