Description

Glyceryl p-Aminobenzoate is a chemical derivative of para-aminobenzoic acid (PABA) esterified with glycerol. This compound is valued for its UV-absorbing properties and its role as a key intermediate in the synthesis of specialty chemicals. It is primarily sought by manufacturers in the personal care, pharmaceutical, and fine chemical industries for applications requiring light stabilization and specific functional group chemistry.

Application

• Sunscreen and Cosmetic Formulations: Acts as an organic UV filter and stabilizer in lotions, creams, and makeup products.
• Pharmaceutical Intermediates: Serves as a crucial building block in the synthesis of active pharmaceutical ingredients (APIs) and prodrugs.
• Polymer Additives: Used as a light stabilizer and antioxidant in plastics and coatings to prevent photodegradation.
• Hair Dye and Colorant Components: Functions as a coupling agent or intermediate in oxidative hair dye systems.
• Research & Development: Employed in academic and industrial laboratories for chemical research and process development.
• Industrial Fine Chemicals: Utilized as a specialty intermediate for further chemical transformations in custom synthesis.
