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-2" 2 propylene glycol molecular units. "ceteth-20" denotes the polyoxyethylene ether of cetylaene alcohol which contains an average of 20 units of the monomer "-CH2-CH2-O- " (see e.g. laurethe as polyoxyethylene ether of lauryl alcohol; steareth as polyoxyethylene ether of stearyl alcohol, etc.)

PPG-2-ceteth-20 is used in cosmetic formulations; the substance acts as emollient (makes the skin smooth and supple).
