Ppg-6-sorbeth-500 (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-23" this is 23 propylene glycol molecular units. "steareth-34" denotes a PEG (polyethylene glycol) ether of stearyl alcohol; the number behind "sorbeth" indicates the average number of ethylene glycol molecules, here 34.

PPG-23-steareth-34 is used in cosmetic formulations. The substance mixture acts as an emollient (makes the skin smooth and supple).
