Polyglycerol polyricinoleate (PGPR), E476, is an emulsifier made from glycerol and fatty acids. It is a yellowish, viscous liquid and is strongly lipophilic: it is soluble in fats and oils and insoluble in water and ethanol.
It is typically used at low levels (below 0.5%) to improve flow behavior and texture in baked goods, spreads, and salad dressings.
