PEG/PPG-10/2 DIMETHICONE.

Valuable / HAIR CONDITIONING, SKIN CONDITIONING - EMOLLIENT

PEG/PPG-10/2 Dimethicone is a versatile silicone surfactant that functions as an emulsifier, skin and hair conditioning agent, and emollient. It reduces surface tension, forming micelles at higher concentrations to support detergency and emulsification.

Science

Mechanism of Action

This nonionic silicone copolymer operates by reducing surface tension within formulations, facilitating the blending of oil and water phases. It forms a breathable film on the skin, contributing to conditioning and emollient effects while also stabilizing emulsions and increasing product viscosity. Its micelle-forming capability further enhances cleansing and emulsification.

Safety

Safety Profile

CIR Status
Safe as used
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has concluded that PEG/PPG-10/2 Dimethicone, within the group of Polyoxyalkylene Siloxane Copolymers, is 'safe as used', a conclusion reiterated from earlier assessments. Clinical studies using related ingredients like Dimethicone Copolyol at concentrations up to 40% in aqueous solutions and undiluted showed no primary skin irritation. However, it is noted that PEGs can function as penetration enhancers, and in certain individuals, may potentially trigger anaphylaxis or hypersensitivity reactions.
