The function of glycyrrhizin is to foam, forming small, condensed bubbles. These bubbles, or foam,
help to disperse the ingredients of the toothpaste throughout the mouth when brushing. Tom’s of Maine has
applied for a patent, which is pending, on this natural foaming process.
Sodium lauryl sulfate (SLS), which is processed from coconuts, is the most common alternative, and
one that Tom’s of Maine uses. We developed glycyrrhizin to replace SLS in some of our toothpastes because
we’re always looking for new ways to formulate our product, and glycyrrhizin represents an innovative new
choice for our consumers. These are our SLS-free products:
Clean & Gentle Care SLS-Free Anticavity plus Whitening Fluoride Toothpaste
Clean & Gentle Care SLS-Free Antiplaque plus Whitening Fluoride-Free Toothpaste
* Natural Sensitive Care SLS-Free
Glycyrrhizin has no known carcinogenicity and is on the U.S. Food and Drug Administration’s list of
ingredients that are Generally Recognized As Safe (GRAS).
Tom's of Maine recognizes that no
two people are alike, and even with pure and natural ingredients, some individuals may develop an allergic
reaction that is unique to them. As with any product, be sure to discontinue use if you experience discomfort
or other indications that the product may not be appropriate for your individual body chemistry.
Glycyrrhizin is a sweet-tasting compound purified from the root of the licorice plant.
