"Polyethylene glycol (PEG) is a water-soluble lubricant from petroleum and/or mineral sources. PEG may be used as a binding agent, coating agent, dispersing agent, flavoring adjuvant, and plasticizer. Supplement manufacturers use it as a processing aid in compression enabling the tablets to hold together better. It also protects nutrients in the tablet from air and humidity.
PEG is approved for use under the 21 CFR 172.820, and 173.340. It can be added to carbonated beverages, citrus fruit, non-nutritive sweeteners, tablets, and vitamin or mineral preparations.
