Uses and Benefits of Glycerin in Personal Care and Cosmetic Products

Glycerin, also known as glycerine or glycerol, is a clear, colourless and viscous ingredient widely used across personal care, cosmetics, pharmaceuticals, food processing and industrial manufacturing. It is valued primarily for its humectant properties, meaning it attracts and binds water. This functionality helps formulations retain moisture, maintain texture and improve the feel of finished products. The FDA also identifies glycerin as a humectant, solvent, stabilizer, thickener and texturizer in appropriate applications.

glycerin draw water into the outer layer of the skin and supports skin-barrier hydration. It is commonly incorporated into moisturizers, lotions, creams, cleansers, hand sanitizers and lip-care products. Dermatologists include glycerin among the ingredients suitable for relieving dry skin, and research supports its moisture-retention and skin-hydration properties.

Glycerin is used in facial creams, body lotions, hand creams, liquid soaps, shampoos, conditioners, lip balms, foot creams, nail and cuticle products, facial cleansers and oral-care products. In hair-care systems, it can support moisture retention and product texture, while in foot and nail-care formulations it helps soften dry, rough areas. Claims should describe the finished product’s cosmetic function rather than state that glycerin cures medical conditions.

Refined glycerin is used as a solvent, vehicle, humectant, sweetener and formulation aid in pharmaceutical, oral-care, food and industrial products. Appropriate glycerin grade-such as USP, BP, EP, food grade or technical grade-must be selected according to the intended application and destination-market requirements. Mars Oleochemicals supplies refined glycerin for manufacturers, importers and distributors worldwide, subject to grade, specification and availability.
