PEG/PPG-20/6 Dimethicone

What is PEG/PPG-20/6 Dimethicone?

PEG/PPG-20/6 Dimethicone is a synthetic silicone-based copolymer derived from dimethicone modified with polyethylene glycol (PEG-20) and polypropylene glycol (PPG-6) chains. This polyether-modified polydimethylsiloxane belongs to the category of silicone surfactants commonly used in rinse-off and leave-on cosmetics like shampoos, conditioners, creams, and lotions. It works by significantly lowering surface tension at interfaces, which facilitates the formation of stable emulsions by creating a protective film around oil droplets in water-based systems or vice versa. This property makes it ideal for water-in-silicone or silicone-in-water formulations, promoting even distribution, enhanced wetting on skin or hair, and a lightweight, silky sensory feel without residue. In products, it aids in solubilizing fragrances or active ingredients and contributes to foaming in cleansers.
