What is Polyglycerol polyricinoleate?
Polyglycerol polyricinoleate (CAS 29894-35-7), commonly identified as PGPR or E476, is a food-grade emulsifier derived from polyglycerol esters of polycondensed fatty acids from castor oil.
Where is Polyglycerol polyricinoleate used?
- Chocolate and compound coatings: reduces flow resistance during enrobing and moulding, allowing lower cocoa butter content without sacrificing coverage quality
- Confectionery fillings and fat-based spreads: stabilizes water-in-oil emulsions and prevents phase separation
- Bakery: improves workability of fat-based icings
- Personal care: lipophilic emulsifier and rheology modifier in anhydrous systems such as lip products and skin balms
- It reduces viscosity in fat-based systems and controls the interaction between water droplets and continuous fat phases.
Good to know: Purity and acid value parameters are aligned to regulatory requirements in the EU, US, and Codex Alimentarius markets.
Commercial specifications
- Food-grade material to FCC and E476 specifications
