Ppg-4 trideceth-6 (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-4" this is 4 propylene glycol molecular units.

PPG- trideceth-6 is used in cosmetic formulations. The mixture of substances acts as an emollient (makes the skin smooth and supple) and as an emulsifier (surface-active substance which is used in cosmetic products as an additive to combine 2 immiscible liquids - e.g. oil and water - to form an emulsion).
