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-3" this is 3 propylene glycol molecular units. "isosteareth-9" denotes a PEG ether of isostearyl alcohol. The number 9 indicates the average number of integrated polyethylene monomers "-CH2-CH2-O-".

PPG-3-isosteareth-9 is used in cosmetic formulations. The mixture of substances acts as an emulsifier (surface-active substance which is used in cosmetic formulations as an additive to combine two immiscible liquids - e.g. oil and water - to form an emulsion).
