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-6" this is 6 propylene glycol molecular units.
PPG-6 C12-18 pareth-11 is used in cosmetic formulations. The substance mixture acts as an emollient (makes the skin smooth and supple).
