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-77" this is 77 propylene glycol molecular units. "trimethylolpropane (1,1,1-tris(hydroxymethyl)propane)" is an alcoholic component of the ether (ether) linkage.
PPG-77 trimethylolpropane ether is used in cosmetic formulations. The substance mixture acts as a skin care product.
