PEG/PPG-20/60 COPOLYMER.

Valuable CAS - / CLEANSING, SOLVENT, SURFACTANT - CLEANSING

PEG/PPG-20/60 Copolymer is a multifunctional polymer acting as an emulsifier, surfactant, and viscosity controller within formulations. On the skin, it provides emollience and forms a film to mitigate transepidermal water loss, contributing to enhanced hydration. INCIDecoder rates this ingredient as "good" for its versatility.

Science

Mechanism of Action

As an amphiphilic polymer, PEG/PPG-20/60 COPOLYMER effectively reduces surface tension, facilitating the stable combination of immiscible oil and water phases within a formulation. Applied to the skin, its polymeric structure creates a protective, non-occlusive film that aids in reducing transepidermal water loss, thereby supporting skin hydration and providing emollient benefits.

Safety

Safety Profile

CIR Status
Safe as used
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) panel concluded that polyethylene glycols (PEGs) across a wide molecular weight range (200 to over 10,000) and polypropylene glycols (PPGs) (≥3) are safe for cosmetic use, provided formulations are non-irritating to intact skin. These compounds exhibit low ocular and dermal irritation potential. However, it's advised that manufacturers minimize impurities like ethylene oxide and 1,4-dioxane. It is also noted that PEGs can penetrate skin that is injured or compromised. Poloxamer 407, a similar PEG/PPG block copolymer, is FDA-approved as a drug delivery excipient in topical pharmaceuticals.
