What is Trimyristin?
Trimyristin (CAS 555-45-3) is a naturally occurring triglyceride derived primarily from nutmeg kernel fat, where it constitutes the dominant lipid fraction.
Where is Trimyristin used?
- Cosmetics: occlusive emollient and texturizer in stick formats, body butters and skin conditioning bases
- Pharmaceuticals: lipid matrix former in sustained-release suppositories
- Lipid-based drug delivery: defined melting behaviour supports controlled API release
- Food manufacturing: cocoa butter analog and structuring fat in confectionery coatings
- It also serves as a carrier matrix in lipid nanoparticle systems for encapsulation.
Good to know: Material sourced from natural nutmeg fat is standard; synthetic or semi-synthetic grades are available for tighter purity control.
Commercial specifications
- High-purity research grades for formulation development
