PEG/PPG-23/6 DIMETHICONE.

Valuable CAS - / EMULSION STABILISING, SURFACTANT - CLEANSING

PEG/PPG-23/6 Dimethicone is a sophisticated silicone-polyether copolymer engineered to deliver multifunctional benefits in skincare formulations. It combines the sensory enhancements of dimethicone with the solubility and emulsifying properties of polyethers, resulting in improved skin feel and product stability.

Science

Mechanism of Action

This ingredient functions as a surface tension-reducing molecule. The dimethicone component imparts a smooth, non-greasy skin feel, while the polyether (PEG/PPG) segment facilitates emulsification, enhances ingredient compatibility, and modifies solubility. It acts as an emollient and humectant, contributing to skin hydration and an improved tactile experience without sticky residue.
