What is it? ​

Polyglycerol polyricinoleate (PGPR) is a distinctive emulsifier made by esterifying polyglycerol with ricinoleic acid (and some other fatty acids). It is a lipophilic emulsifier and viscosity reducer that markedly lowers the viscosity of fat systems such as chocolate, reducing cocoa-butter need.

In a nutshell ​

PGPR (polyglycerol polyricinoleate) is a strong viscosity-reducing lipophilic emulsifier used mainly to lower chocolate fat viscosity.

Consumer Advice ​

Polyglycerol polyricinoleate (PGPR) is made from ricinoleic acid derived from castor oil and polyglycerol. It is a water-in-oil emulsifier whose main use is in chocolate, where it lowers the viscosity of molten chocolate so it flows and sets more easily, allowing less cocoa butter to be used. It also appears in some sauces and low-fat spreads. JECFA set an acceptable daily intake of 7.5 mg per kg of body weight, and it is safe at normal consumption levels.
