PEG/PPG-28/30 COPOLYMER.

Valuable CAS - / CLEANSING, SOLVENT, SURFACTANT - CLEANSING

PEG/PPG-28/30 Copolymer is a highly adaptable nonionic triblock copolymer renowned for its multifunctional properties in skincare formulations. It primarily functions as an emulsifier and solubilizer, enabling the stable dispersion of oil and water phases, while also serving as an emollient and humectant to enhance skin hydration and texture.

Science

Mechanism of Action

This copolymer operates by reducing the surface tension of liquids, which is crucial for solubilizing immiscible substances like oils and water into stable, homogeneous mixtures. On the skin, it functions as a humectant by attracting and retaining moisture, similar to glycerol, while its emollient properties contribute to a smooth skin feel. Additionally, it improves the spreadability of formulations and can enhance the resistance of products to water, sweat, or rub-off, forming a protective, aesthetic film.
