About
A high molecular weight polyethylene glycol used as a binder and viscosity-controlling agent that helps maintain product consistency and structural integrity.
PEG-5M is a polyethylene glycol polymer with approximately 5,000 ethylene oxide units. Its high molecular weight ensures minimal systemic absorption and low irritation potential. EU regulatory framework permits this polymer class as a viscosity-controlling agent in cosmetics; it is listed in Annex V of the Cosmetics Regulation. Like all PEG polymers, compliance with purity standards for residual monomers (ethylene oxide, 1,4-dioxane) is mandatory for market access in the EU.
Skin benefits
- Functions as a binder to improve product cohesion and texture
- High molecular weight humectant helps retain moisture on skin
Known concerns
- Residual monomer contamination must be controlled to meet EU purity standards
- Use in broken or barrier-compromised skin requires additional safety consideration
