Ppg-3 hydrogenated castor oil (inci)

PPG is the acronym for "polypropylene glycol", the polymer of propylene glycol (1,2-propanediol), a dihydric alcohol. The number after "PPG" indicates the average number of propylene glycol molecular units, for "PPG-3" this is 3 propylene glycol molecular units. "Hydrogenated castor oil" refers to the hydrogenated (hardened) castor oil. PPG-3 hydrogenated castor oil thus designates a polypropylene fatty acid compound based on fatty acids from castor oil. The substance mixture is used in cosmetic formulations. It acts as an emulsifier (surface-active substance which is used in cosmetic products as an additive to combine 2 immiscible liquids - e.g. oil and water - to one emulsion), as a surfactant (washing-active substance; improves the even distribution of the products during application) and as an emollient (makes the skin smooth and supple).
