Glycerol is a clear, colorless, viscous liquid widely used as a humectant, solvent, plasticizer, and sweetening agent in pharmaceutical, cosmetic, food, and industrial formulations.

In oral and topical pharmaceuticals, it improves moisture retention, enhances mouthfeel, and stabilizes solutions, syrups, suppositories, and gels.

It acts as a co-solvent for many active ingredients, supports preservation by reducing water activity, and contributes mild sweetness without causing tooth decay.

In skin-care and personal-care products, glycerol helps maintain skin hydration and barrier function, providing a smooth, soft feel.

Its excellent safety profile, compatibility, and multifunctionality make glycerol one of the most widely used excipients globally.
