Science
Mechanism of Action
PEG-CROSSPOLYMER operates by forming a breathable, continuous film on the skin, which aids in reducing transepidermal water loss. Its humectant capabilities enable it to attract and retain water through hydrogen bonding, thereby delivering sustained hydration beneficial for various skin conditions, particularly dryness. Within formulations, it functions as an effective emulsifier, stabilizing mixtures of oil and water, and as a viscosity modifier to achieve desired product consistency. It also contributes to a refined sensory experience, imparting a silky, powdery finish that enhances texture and spreadability, and can offer a soft optical effect to visibly minimize skin imperfections.

Formulation
Stability
PEG-CROSSPOLYMERs are amphiphilic, featuring both hydrophilic PEG and hydrophobic crosspolymer/silicone components, which enables their dispersion in water and solubility in surfactants, facilitating the mixing of water and silicone oils. These crosslinked polymers generally exhibit superior chemical stability and reduced solubility compared to their non-crosslinked counterparts. They maintain stability within a functional pH range of approximately 4.0 to 9.0 and are stable at moderate salt levels.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has evaluated PEG-CROSSPOLYMER ingredients, alongside various alkyl polyethylene glycol ethers and dimethicone crosspolymers, deeming them safe for use in cosmetic applications at current concentrations, provided the final formulation is non-irritating. While the manufacturing of some PEG-related compounds may present a potential for 1,4-dioxane contamination, this concern can be effectively managed through proper filtration processes.
