Polypropylene glycol (PPGs) and their derivatives are used in cosmetic products like the polyethylene glycols (PEGs). They are often used in cosmetic products since they have a broad range of viscosity and solubility properties and have a very good skin tolerance. As water soluble, non-greasy substances, polypropylene glycols are suited for many cosmetic purposes.
