-EINECS number: 250-705-4

Main uses and application areas
The core functions of this substance are emulsification, stability, and thickening. Most commercially available products are mixtures of monoesters and diesters. High purity monoesters (≥ 90%) have significantly improved emulsifying properties after molecular distillation purification.
1. Food industry: anti-aging of bread, biscuits and cakes, texture improvers such as ice cream, margarine and sausage (food additive code E471);
2. Pharmaceutical field: excipients and emulsifying stabilizers in ointments and cream matrices;
3. Daily chemical cosmetics: cream, lotion, shampoo as emulsifier and thickener;
4. Other industries: plastic additives (PVC stabilizers, anti-static agents), pesticide droppers, coating dispersants, etc.

Preparation and Safety Overview
In industry, glycerol and stearic acid are usually esterified at high temperatures using alkaline catalysts such as sodium hydroxide; It belongs to low toxicity substances and is not a hazardous chemical. It should be stored in a sealed, cool, and dry place.
