PEG-7 DIMETHICONE.

Valuable / HAIR CONDITIONING, SKIN CONDITIONING

A water-dispersible silicone polymer, PEG-7 Dimethicone functions as a versatile skin and hair conditioning agent, forming a protective, temporary barrier on the skin while visibly smoothing its texture and enhancing hydration.

Science

Mechanism of Action

PEG-7 Dimethicone operates by creating a fine, temporary occlusive layer on the skin's surface. This barrier effectively minimizes transepidermal water loss (TEWL), thereby supporting skin hydration and offering protection against external irritants and allergens. Its unique silicone structure also allows it to fill in microscopic fine lines and textural irregularities, resulting in a perceptibly smoother skin surface.

The Cosmetic Ingredient Review (CIR) Expert Panel has affirmed the safety of Dimethicone and its related polymers, including PEG-7 Dimethicone, in cosmetic applications. Due to its substantial molecular weight, significant dermal absorption is not anticipated. While PEG compounds sometimes raise concerns regarding manufacturing impurities, suppliers confirm their safety for cosmetic inclusion. The specified maximum concentration of 85% pertains to general dimethicone in dermal contact products; PEG-7 Dimethicone specifically is designated as 'safe as used' without a lower explicit restriction.
