Propylene glycol is a clear, hygroscopic liquid used as a solvent, humectant, plasticizer, and co-emulsifier in pharmaceuticals, cosmetics, and food.
It solubilizes many APIs, flavors, and preservatives, making it valuable in oral solutions, injectables (where permitted), semi-solids, and topical sprays.
As a humectant, it helps retain moisture in creams, gels, and personal-care products, enhancing texture and skin feel.
Propylene glycol is miscible with water and many organic solvents and has a strong regulatory track record when used within approved limits.
