Lauryl PEG-9 Polydimethylsiloxyethyl Dimethicone

PEG / Ethoxylated

What is Lauryl PEG-9 Polydimethylsiloxyethyl Dimethicone?

Lauryl PEG-9 Polydimethylsiloxyethyl Dimethicone is a synthetic hybrid silicone polymer combining a polydimethylsiloxyethyl dimethicone structure with a lauryl alkyl chain and a polyethylene glycol (PEG-9) hydrophilic segment. Developed for cosmetic formulations, it excels in water-in-silicone emulsions, enabling the blending of aqueous ingredients into silicone oil phases for stable, lightweight products. Typically featured in shampoos, conditioners, foundations, and moisturizers, it deposits a thin, flexible film on hair shafts and skin surfaces. This film minimizes friction, imparts slipperiness during application, and supports even distribution of other components, resulting in enhanced sensory qualities like silkiness without greasiness.
