If you’ve ever investigated the ingredients in your toothpaste, you might have seen glycerin on the list. Also known as glycerol, this natural ingredient is not only found in toothpaste; it’s also a sweetener in foods and found in other cosmetic products as well. Here, we’ll take a deeper dive into glycerin and oral care, as well as the many uses for this versatile ingredient.
Glycerin in Dental Care
What is Glycerin?
Glycerin is a colorless, syrupy liquid that is somewhat sweet. According to Food Insight, it is used in food and beverages for a variety of reasons. It can add sweetness, help retain moisture, add softness or smoothness, prevent sugar from crystallizing, and add bulk and texture. While it has more calories than sugar, it is only about 60-75% as sweet.
Glycerin and Dental Care
As far as glycerin uses for your mouth, this ingredient plays a few different roles in oral care products. Glycerin is commonly found in toothpaste as it provides both sweetness and helps the toothpaste stay creamy and retain moisture, which is why you may find it listed in your toothpaste ingredients. It’s also found in mouthrinses to add body and moisture as well.
Is Glycerin Safe?
The Food and Drug Administration (FDA) considers glycerin generally recognized as safe (GRAS) in food packaging and food substance when used with good manufacturing practices. Also, beyond its use in foods and beverages, glycerin is also a common ingredient in your favorite cosmetics, according to the International Journal of Toxicology. Oral care products that contain glycerin are safe to use but should not be swallowed, as ingesting excessive amounts of glycerin can lead to gas, bloating, and diarrhea.
