CAS 26855-43-6 corresponds to triglycerol monostearate (Triglycerol Monostearate), a nonionic surfactant synthesized by esterification of triglycerol with stearic acid, widely used as an emulsifier, dispersant, and stabilizer in food, cosmetics, and industrial applications.

Core physicochemical parameters
Chemical formula: C₂₇H₅₄O₈
- Molecular weight: 506.71
- Appearance: A pale yellow to amber-colored oily viscous liquid or waxy solid (melting point approximately 53–60°C)
- Solubility: Insoluble in water, soluble in ethanol and fats
- HLB value: Wide range (1–16), with good W/O emulsification capability
- Safety: The oral LD₅₀ in rats is approximately 10 g/kg, indicating low toxicity

Main Application Fields
Food Industry: Used in bread (to delay starch retrogradation, maximum addition 0.1 g/kg), ice cream (to increase volume and preserve freshness, maximum 3.0 g/kg), instant noodles, etc.; complies with GB 2760 standards.
2. Cosmetics: Functions as an emulsifier and thickener for emollient products, enhancing texture stability.
3. Other Industries: Promotes sucrose crystallization in the sugar industry; serves as a plasticizer/lubricant in polymer materials; and is used as a drug carrier or ointment base in the pharmaceutical field.

Preparation and Storage
Synthesis Pathway: Glycerol undergoes high-temperature condensation to form triglycerol, which is then esterified with stearic acid and decolorized to obtain the product.
Storage requirements: Store in a cool, dry place, vacuum-sealed with nitrogen-filled aluminum foil packaging, protected from moisture and light.
