Science
Mechanism of Action
PEG-9 DIGLYCIDYL ETHER/SODIUM HYALURONATE CROSSPOLYMER operates as a highly efficient humectant due to its unique cross-linked structure. It forms a stable, water-filled gel film on the skin, reported to bind water five times more effectively than standard hyaluronic acid. This film acts as a sustained reservoir, continuously releasing bound water to provide long-term moisturizing benefits and maintain skin in optimal condition.

Stability
Polyethylene glycols exhibit diverse viscosity and solubility properties. While hyaluronic acid nanogels, a component of this crosspolymer, display pH-sensitive swelling, and HA is often processed at a pH of 5.4 for crosslinking, the specific optimal pH range for the stability of the final crosspolymer in cosmetic formulations has not been definitively established.
Safety
Safety Profile
While the Cosmetic Ingredient Review (CIR) Expert Panel has deemed general hyaluronates safe, direct and specific safety assessments for PEG-9 DIGLYCIDYL ETHER/SODIUM HYALURONATE CROSSPOLYMER are insufficient. Oral, parenteral, and dermal toxicity for this specific ingredient are undetermined, with no GHS classification or hazard statements found. However, related HA crosslinked with polyethylene glycol diglycidyl ether (PEGDE) in dermal fillers has shown favorable biocompatibility, reducing cytotoxicity, oxidative stress, and inflammation. In China, historical usage for systemic leave-on cosmetic products containing this ingredient is reported up to 0.0025%.
