PEG/PPG-1/2 COPOLYMER.

Valuable CAS 9003-11-6 (generic) / SOLVENT

PEG/PPG-1/2 Copolymer is a synthetic polymer engineered for versatile application in skincare formulations. It primarily functions as an effective solvent and solubilizer for various cosmetic components, including actives and fragrances. Additionally, it enhances product consistency, provides humectant properties, and serves as a binding and softening agent.

Solvent Solubilizer Humectant Consistency Enhancer Binding Agent Softening Agent Fixative

Science

Mechanism of Action

This copolymer operates through its amphiphilic structure, allowing it to effectively solubilize lipophilic active ingredients, fragrance oils, and colorants within aqueous phases, ensuring uniform dispersion. As a humectant, it draws and retains moisture, contributing to skin hydration. Its polymeric chain also modifies the rheology of formulations, acting as a consistency enhancer, binding agent, softening agent, and a fixative within the cosmetic matrix.

Stability

While specific stability data for PEG/PPG-1/2 Copolymer is not extensively documented, related PEG-PPG-PEG copolymers demonstrate stability at neutral pH, typically around pH 7.4. Degradation may occur under acidic conditions, observed at pH values such as 5.0 and 6.5.

Safety

Safety Profile

CIR Status
Safe as used with restrictions
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has deemed related alkyl PEG/PPG ethers safe in current cosmetic uses and concentrations, provided they are formulated to be non-irritating. The inclusion of PPG units did not introduce additional safety concerns, as PPGs have been independently reviewed and found safe when formulated appropriately. General considerations for all PEG-derived ingredients include potential residual levels of starting materials (ethylene oxide, propylene oxide), by-products (1,4-dioxane), and the possibility of enhanced skin penetration of other ingredients.
