Glycerol is used as a holding agent in tablets, in suppositories, and as a laxative. It stimulates intestinal contractions and promotes water absorption into the lower large intestine, thereby supporting bowel movements. It can also be used topically for a range of skin conditions, including dermatitis, rashes, burns, pressure sores, and cuts. Glycerine has also been used in the treatment of gum disease because it can destroy and inhibit the growth of microorganisms in inflamed oral lesions. In addition, it is used in the management of glaucoma and cerebral edema. When taken orally, glycerine creates an osmotic pressure difference in the eye and brain, drawing fluid back into the bloodstream and reducing pressure in these organs.
Food, Beverage & Supplement
Glycerine functions as a humectant, solvent, sweetener, thickener, and preservative. It is therefore widely used in foods and beverages to enhance and improve various product properties. In the confectionery industry, it is commonly used as a humectant and texture improver, such as helping prevent moisture-related issues in icing and powdered foods and beverages, and adding viscosity, texture, and sweetness to candies, chewing gum, cakes, cookies, and cheese.
Glycerine is added to dry animal feed to help control moisture and improve sweetness. In food processing, glycerine may also be used in the form of glycerol esters of fatty acids, which function as emulsifiers and stabilizers in a variety of products.
Skincare, Cosmetics
Glycerine can be used as a lubricating and moisturizing ingredient that helps protect the skin from dryness. It supports aquaporin activity, helping the cells’ water-transport channels function more effectively. It helps maintain skin hydration and absorbs moisture from the air, leaving the skin feeling moisturized. It is gentle on the skin, non-comedogenic, and considered safe for topical use. A publication in Acta Dermato-Venereologica reported that it helps make the skin feel soft and smooth shortly after application. Glycerine also acts as a protective barrier that helps shield the skin from irritation caused by environmental pollutants. It can improve the penetration of other ingredients, helping the skin remain supple and youthful-looking. In 2015, a publication in the Journal of the European Academy of Dermatology and Venereology reported glycerine’s ability to help protect against irritation and soothe inflamed skin.
