Ppg-2-deceth-10 (inci)

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-2" this is 2 propylene glycol molecular units. "deceth-10" denotes a PEG ether of the alkyl alcohol "Decyl alcohol also known as 1-decanol". The number 10 in "deceth-10" denotes the average number of molecular units "-CH2-CH2-O-".

PPG-2-deceth-10 is used in cosmetic formulations. The mixture of substances acts as an emulsifier (surface-active substance which is used in cosmetic formulations as an auxiliary agent to combine 2 immiscible liquids - e.g. oil and water - into one emulsion).
