• Basic Information
  • Molecular Formula: Taking glycerol monostearate as an example, the molecular formula is C₂₁H₄₂O₄.
  • Molecular Weight: Approximately 358.56
  • CAS No. : 123 - 94 - 4
• Physical and Chemical Properties
  • Appearance: Usually white or light - yellow waxy solid or powder, slightly bitter.
  • Solubility: Insoluble in water, soluble in organic solvents such as chloroform, ethyl acetate, ethanol, benzene, and various chlorinated hydrocarbons.
  • HLB Value : The HLB value is between 3 and 5, and it is a water - in - oil (W/O) type emulsifier.
• Product Characteristics
  • Emulsifying Property: There are two hydrophilic hydroxyl groups and one lipophilic hydrocarbon group in the monoglyceride molecule, which has excellent emulsifying performance and can form a stable emulsion of oil and water.
  • Dispersibility: It can disperse oil droplets and pigments, making them evenly distributed in water.
  • Stability: It can stabilize foams and emulsions, preventing them from breaking and separating.
  • Defoaming Property: It can reduce the surface tension of foam, thus eliminating foam.
• Preparation Method
  • The main method is the chemical method, which uses natural fats and oils, fatty acids, glycerol, etc. as raw materials, and synthesizes them through reaction pathways such as oil hydrolysis or alcoholysis, fatty acid and glycerol esterification, and glycerolysis. It can also be synthesized by the enzymatic method using lipase as a catalyst. The enzymatic synthesis has the advantages of mild reaction conditions and high - purity products, but most of the current research is still in the experimental stage, and large - scale commercial production has not been achieved.
• Product Classification
  • Ordinary Monoglyceride: It is a primary product obtained by esterification or alcoholysis without distillation or purification treatment. It is a mixture of monoglyceride, diglyceride, and other components, with a monoglyceride content of generally 35% - 40%.
  • High - Purity Monoglyceride: The ordinary monoglyceride is purified, the catalyst and glycerol are removed, and then high - molecular distillation is carried out to obtain a high - purity monoglyceride with a monoglyceride content of more than 90%.
  • Derivatives of Monoglyceride: The high - purity monoglyceride can be further esterified with organic acids such as acetic acid and lactic acid to form derivatives of monoglyceride, which can be used for special purposes.
• Application Fields
  • Food Field: It can be used as an emulsifier, stabilizer, and preservative in foods such as bread, cakes, and ice creams. It can also be used as a bactericide for the preservation of meat products, dairy products, etc., and for the preservation of fruits.
  • Cosmetics Field: It is used to prepare cosmetic creams, lotions, etc., which can play the roles of emulsification and dispersion, and improve the stability and ductility of products.
  • Other Fields: It can be used as an internal lubricant, anti - fogging agent, and dispersant in the plastic industry, and as a defoamer and emulsifier in the detergent industry.
• Packaging and Storage
  • It is generally packed in 25 - kg bags. It can be stored at room temperature, and the shelf - life is usually about 2 years.
