Glyceryl rosinate

Glyceryl rosinate (CAS 65997-13-9) is a hydrogenated rosin ester produced by reacting glycerol with refined rosin acids, resulting in a pale, thermally stable resin. It functions as a tackifier, plasticizer, and emulsifier across adhesive, cosmetic, and rubber compounding applications.

In personal care, it anchors pigments and waxes in lip products, mascaras, and depilatory waxes, improving adhesion to skin and hair. Rubber compounders incorporate it to improve tack and processing flow in tire and technical rubber formulations.

Printing ink manufacturers use it as a resin binder and film-forming component in solvent-based and heat-set ink systems. In pressure-sensitive adhesives and hot-melt formulations, it improves bond strength and compatibility with polymer matrices.

The material is highly compatible with polymers such as SIS and EVA, making it a versatile choice for industrial bonding. It provides excellent thermal stability and resistance to oxidation during high-temperature processing cycles.

Glyceryl rosinate is supplied as pale yellow to amber solid flakes, pellets, or blocks. Technical and cosmetic-grade material is available, with cosmetic-grade product meeting purity requirements relevant to personal care formulation standards.

Softening point and acid value specifications vary by grade, and buyers typically request technical data sheets to confirm suitability. This ensures the material meets specific processing conditions and performance requirements for the end product.
