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, e.g. "PPG-38" has 38 propylene glycol molecular units.

Buteth(e) are polyoxyethylene ethers which can be formally derived from the structure of butyl alcohol (for comparison see: laurethe as polyoxyethylene ether of lauryl alcohol; steareth as polyoxyethylene ether of stearyl alcohol etc.). In the name of butethe, the numbering added means the average number of ethylene oxide units per mole. Buteth-37 is the INCI designation for a polyoxyethylene ether with 37 ethylene oxide units per mole. PPG-38-buteth-37 is used in cosmetic formulations. The substance mixture acts as a moisturizer (increases the water content of the skin).
