Zemea® propanediol is a 100% plant-based alternative to petroleum-based glycols and glycerin. Used as a humectant in a wide range of skin care applications, this pure ingredient enhances moisturization and reduces tackiness for a better feel. Zemea® also boosts the efficacy of active ingredients when used as a solvent, and can reduce the need for added preservatives.
