Glyceryl Polymethacrylate, commonly known as Lubrajel CG, is a water-soluble organic polymer with the chemical formula C₇H₁₄O₅ and a molecular weight of 178.18. It typically exists as a transparent gel, often formulated with propylene glycol for enhanced performance. Key properties include excellent water solubility (also compatible with alcohols), stability against light, heat, and oxygen, low toxicity, and good biocompatibility. Its non-irritating nature and versatile functionality make it widely used across cosmetics, biomedicine, and industrial sectors.

Core Application Scenarios

Cosmetics & Personal Care: As a primary application field, it serves as a film-forming agent, viscosity controller, and moisturizing base. It stabilizes the texture of skincare products and cosmetics to prevent stratification, replenishes and locks in skin moisture, and enhances product spreadability. It is commonly added to transparent or colorless emulsions, gels, lotions, lip balms, and moisturizers.

Biomedical Materials: Leveraging its hydrophilicity and biocompatibility, it is used in manufacturing hydrogels, drug delivery systems, and wound dressings. In drug release formulations, it enables sustained and controlled drug release to extend efficacy. For wound care, it maintains a moist environment to promote healing and reduce scarring.

Industrial Sector: Acts as a modification additive in coatings and adhesives. It improves the film flexibility of coatings and enhances the adhesion of adhesives on various substrates, ensuring stable bonding performance for industrial production needs.
