Ppg-15-peg-11 hydrogenated lauryl alcohol ether (inci)

PPG-15 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-15" this is 15 propylene glycol molecular units.

"PEG" means "polyethylene glycol", a polymer (macromolecule of low-molecular monomers - basic building blocks) of ethylene oxide (-CH2-CH2-O-). The number 11 after "PEG-" indicates the average number of ethylene oxide units, here 11 molecular units. "hydrogenated lauryl alcohol ether" refers to a hydrogenated (hardened) lauryl ether compound.

PPG-15-PEG-11 hydrogenated lauryl alcohol ether is used in cosmetic formulations. The mixture of substances acts as an emulsifier (surface-active substance which is used in cosmetic products as an additive to combine two immiscible liquids - e.g. oil and water - into one emulsion) and as a surfactant (washing-active substance; improves the even distribution of the products during application).
