Crest rinse products are labeled “alcohol free”,the only questionable item was the glycerin
and according to the company the glycerin is from a vegetable source.
Thanks for contacting Crest. Crest Pro-Health Rinse does not contain any Animal-by products. The glycerin used in the rinse is from a vegetable source. Thanks for writing Beth Crest Team
