PEG-12 DIMETHICONE CROSSPOLYMER.

Valuable / LIGHT STABILIZER, SURFACTANT - EMULSIFYING, VISCOSITY CONTROLLING

A sophisticated silicone-based polymer, PEG-12 Dimethicone Crosspolymer is designed to improve product aesthetics and skin hydration. It functions as an emulsifier, film-former, and conditioning agent, delivering a smooth, non-greasy finish.

Science

Mechanism of Action

Utilizing an amphiphilic structure comprising both hydrophilic polyethylene glycol (PEG) and hydrophobic dimethicone components, PEG-12 Dimethicone Crosspolymer effectively stabilizes oil-in-water or water-in-oil emulsions by reducing interfacial tension. On the skin, it forms a breathable, non-occlusive film that acts as an emollient to soften and smooth, and as a humectant to help retain moisture. This ingredient is also instrumental in enhancing product texture, imparting a silky-powdery feel, optimizing spreadability, and serving as an efficient delivery system for both water and oil-soluble active compounds.

Safety

Safety Profile

CIR Status
Safe as used
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has affirmed the safety of dimethicone crosspolymer ingredients, including PEG-12 Dimethicone Crosspolymer, within current cosmetic applications and concentrations. Extensive dermal and ocular exposure tests showed minimal to no irritation or sensitization, and genotoxicity was absent. While generally safe for topical application on healthy skin, potential concerns exist regarding trace impurities like ethylene oxide and 1,4-dioxane if purification is insufficient. Therefore, it is advised to avoid products containing PEGs on compromised or irritated skin.
