Glyceryl tripalmitate

Glyceryl Tripalmitate (CAS 555-44-2), also known as Tripalmitin or Trihexadecanoin, is a saturated triglyceride composed of three palmitic acid chains esterified to a glycerol backbone. It carries no assigned E-code and is registered under EC 209-098-1 with HS code 29157090.

In pharmaceutical solid lipid nanoparticle formulations, Glyceryl Tripalmitate acts as a structuring lipid matrix, controlling active ingredient release through its defined melting behaviour. In personal care, it functions as an occlusive emollient and co-emulsifier, stabilising water-in-oil systems and reducing transepidermal moisture loss. Food-grade applications use it as a fat crystal modifier in confectionery coatings.

Glyceryl Tripalmitate is available as a fine crystalline powder in food-grade and pharmaceutical-grade specifications, with compliance traceable to REACH registration requirements. Relevant quality benchmarks include FCC and Ph.Eur. monograph standards for triglyceride purity. Packaging is typically offered in multi-kilogram quantities suited to industrial procurement volumes.
