Polyglycerol polyricinoleate - Wikipedia
Polyglycerol polyricinoleate (PGPR), E476, is an emulsifier made from glycerol and fatty acids (usually from castor bean, but also from soybean oil). In chocolate, compound chocolate and similar coatings, PGPR is mainly used with another substance like lecithin [2] to reduce viscosity.
Polyglycerol - an overview | ScienceDirect Topics
Polyglycerol is a highly branched polyol that is clear and viscous, highly soluble in water and in other polar organic solvents such as methanol, and essentially non-volatile at room temperature [57]. At room temperature, polyglycerol is highly viscous, and the viscosity increases with molecular weight.
