GLYCERYL PPG-16/SMDI HEA/HYDROXYISOPROPYL METHACRYLATE.

Valuable CAS 143708-48-9 / FILM FORMING

This advanced polymer functions primarily as a skin-conditioning agent, forming a breathable barrier that optimizes moisture retention. It also contributes to improved skin texture, enhancing suppleness and elasticity, while serving as a valuable emulsifier and stabilizer in formulations.

Film Forming Moisturizing Skin Conditioning Emulsifying Stabilizing

Science

Mechanism of Action

On application, GLYCERYL PPG-16/SMDI HEA/HYDROXYISOPROPYL METHACRYLATE creates a continuous, breathable film across the skin's surface. This film acts as a physical barrier, effectively minimizing transepidermal water loss (TEWL) to sustain hydration levels. Beyond moisture retention, it actively conditions the skin, promoting a smoother texture and increasing both softness and elasticity. Furthermore, its amphiphilic nature allows it to effectively emulsify disparate phases and stabilize cosmetic formulations, ensuring consistent product integrity and uniform application.

Stability

The polypropylene glycol (PPG) components within this ingredient are recognized for their excellent skin compatibility and versatile properties across a range of viscosities and solubilities. For stability, the methacrylate monomer constituents typically incorporate a polymerization inhibitor and necessitate storage in an oxygenated atmosphere at temperatures not exceeding 35 °C to prevent premature polymerization.

Safety

Safety Profile

CIR Status
Safe with restrictions
Sensitization risk Moderate

The Cosmetic Ingredient Review (CIR) Expert Panel has deemed related methacrylate ester monomers safe for use in nail enhancement products specifically when direct skin contact is meticulously avoided, owing to their inherent sensitizing potential. For this broader ingredient category (Glyceryl Polymethacrylate), studies generally indicate a low propensity for irritation or allergic responses; however, individual sensitivity can occur, suggesting a preliminary patch test for those with reactive skin. This ingredient is broadly approved for use in cosmetic formulations within the EU and US, adhering to relevant regulatory guidelines.
