Ppg-12 laneth-50 (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-12" it is 12 propylene glycol molecular units. "laneth-50" denotes PEG ethers of "lanolin alcohols". The number 50 indicates the average number of integrated polyethylene monomers "-CH2-CH2-O-".

PPG-12 laneth-50 is used in cosmetic formulations. The mixture of substances acts as emulsifier (surface-active substance which is used in cosmetic products as an additive to combine 2 immiscible liquids - e.g. oil and water - to one emulsion) and as surfactant (washing-active substance; improves the even distribution of the products during application).
