What is DEG?
Diethylene glycol (DEG), also known as “diglycol,” is a poisonous chemical used in antifreeze and as a solvent. By way of background, we believe the DEG was present in the glycerin product, which is used in our toothpaste formulation, as it is in the formulation of many leading US toothpaste brands. Glycerin is an important and safe ingredient in toothpaste. DEG has many properties that perform similarly to glycerin, but DEG is not a safe ingredient for toothpaste. DEG is not in our toothpaste formulation, and DEG should never have been used in the manufacture of our toothpaste.
