PPG is the acronym for "polypropylene glycol", the polymer of propylene glycol (1,2-propanediol), a dihydric alcohol. Propylene glycol is thus the building block (monomer) from which all polypropylene glycols (PPGs) are made. The short-chain PPGs are dipropylene glycol, tripropylene glycol and tetrapropylene glycol. The long-chain PPGs are identified by the number after "PPG-". This number indicates the average number of propylene glycol molecular units, for example "PPG-33" has 33 propylene glycol molecular units.
PPG-33 is used in cosmetic products. The substance acts as a skin care product (keeps the skin in good condition).
