Glycerol distearate (type I) EP 
Glyceryl distearate NF 
Glyceryl palmitostearate (USA FDA IIG)

Key Features

  • Fine white powder of well-controlled particle size distribution with an indicative particle size of 50µm
  • A high melting point lipid for use in modified release oral solid dosage forms (lipid matrix for sustained release, delayed release).
  • Use in coating techniques to provide taste masking.
  • In coating techniques the physicochemical properties and plasticity of the lipid film provides high resistance to fracture, useful for flash melt and chewable tablets.
  • Effective lubricant for capsule filling.
  • Chemically inert and compatible with other ingredients.


Safety of use is supported by toxicological data, GRAS status and precedence of use in approved pharmaceutical products.
