The castor oil part is plant-based; the glycerol is usually plant but can be animal. Check for a vegan label.
Depends on the glycerol source. Look for halal certification.

Rules by country
Allowed in chocolate in the US (a GRAS notice FDA accepted), the EU and Canada, with use limits. EFSA re-checked it in 2017 and set a daily limit of 25 mg per kg of body weight.
How much is too much? (Acceptable Daily Intake)
Based on 25 mg per kg of body weight (EFSA / JECFA). A 20 kg (44 lb) child: 500 mg a day.
What is it?
PGPR lowers the thickness of melted chocolate so it coats and molds easily. A fraction of a percent replaces several percent of costly cocoa butter.
Where it comes from: Made by joining glycerol molecules into chains and bonding them to fatty acids from castor oil. The glycerol is usually from plant oils but can come from animal fat.
Why it’s in food
- Lets melted chocolate flow into molds with less cocoa butter
- Helps chocolate coat candy bars and ice cream thinly
- Keeps low-fat spreads from separating
Often found in
Also listed as: PGPR, Polyglycerol polyricinoleate, Polyglycerol esters of interesterified ricinoleic acid, Polyglycerol esters of polycondensed fatty acids of castor oil
Health & gut impact
EFSA found no safety concern at current intakes and raised its daily limit to 25 mg per kg of body weight.
EFSA Panel on Food Additives (2017)
At very high doses, rats developed enlarged livers and kidneys. Those doses are far above what chocolate provides.
