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.

Where is Glyceryl rosinate used?

• Adhesives: tackifier, plasticizer and emulsifier
• Personal care: anchors pigments and waxes in lip products, mascaras and depilatory waxes
• Rubber compounding: improves tack and processing flow in tire and technical rubber formulations
• Printing inks: resin binder and film-forming component in solvent-based and heat-set systems
• In pressure-sensitive adhesives and hot-melt formulations it improves bond strength and compatibility with polymer matrices.

Good to know: Highly compatible with polymers such as SIS and EVA. Softening point and acid value specifications vary by grade; buyers typically request technical data sheets to confirm suitability.

Commercial specifications

• Cosmetic-grade product meets purity requirements relevant to personal care formulation standards
• Softening point and acid value specifications vary by grade
