Description
Glyceryl trimyristate, also known as trimyristin, myristin, or by the abbreviations TG(42:0) and TAG(42:0), is a saturated triglyceride composed of three myristic acid chains esterified to a glycerol backbone. It carries no E-code designation and is registered under CAS 555-45-3 and EC 209-099-7.
In pharmaceutical formulations, glyceryl trimyristate functions as a lipid-based carrier in solid lipid nanoparticles and suppository bases, where its defined melting behaviour controls drug release rates. In cosmetic applications, it acts as an emulsifier and structuring agent in anhydrous systems, stabilising oil-phase components through its crystalline matrix.
Glyceryl trimyristate is supplied as a powder and is available in food-grade and pharmaceutical-grade specifications aligned with FCC and Ph.Eur. standards where applicable. The substance falls under REACH regulation and is classified under HS code 29159000. Procurement enquiries should specify intended application to confirm the appropriate grade.
