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. "deceth-2" denotes a PEG ether of the alkyl alcohol "Decyl alcohol also known as 1-decanol". The number 2 in "deceth-2" denotes the average number of molecular units "-CH2-CH2-O-". Carboxylic acid" generally refers to a carboxylic acid.

PPG-3-deceth-2 carboxylic acid is used in cosmetic formulations. The substance mixture acts as an emollient (makes the skin smooth and supple).
