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-15" this is 15 propylene glycol molecular units. "stearyl ether" refers to an ether (ether) compound of stearyl alcohol.
PPG-15-stearyl ether is used in cosmetic formulations. The substance mixture acts as an emollient (makes the skin smooth and supple).
