What is 1,3-dipalmitin?
1,3-Dipalmitin (CAS 502-52-3), also known as Glyceryl 1,3-dipalmitate, is a symmetric diacylglycerol derived from palmitic acid and glycerol.
Where is 1,3-dipalmitin used?
- Food: modifies fat crystallization behaviour in structured lipid systems
- Confectionery and specialty fats: influences texture and mouthfeel
- Pharmaceuticals: lipid-based drug delivery systems and solid lipid nanoparticles
- Personal care: softening and emulsifying component in creams, lotions and stick formulations
- It also serves as a reference standard and research reagent for lipidomics studies and diacylglycerol metabolism research.
Good to know: Its defined fatty acid positioning affects encapsulation efficiency and release profiles.
Commercial specifications
- Research-grade and high-purity grades for pharmaceutical and analytical applications
- Packaging from small laboratory quantities to bulk industrial formats
