Ppg-1-peg-9 lauryl glycol ether (inci)

PPG-1 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-1" this is 1 propylene glycol molecular unit.

"PEG" means "polyethylene glycol", a polymer (macromolecule of low-molecular monomers - basic building blocks) of ethylene oxide (-CH2-CH2-O-). The number 9 after "PEG-" indicates the average number of ethylene oxide units, here 9 molecular units. "lauryl glycol ether" refers to the ethoxylated and propoxylated lauryl alcohol in an ether compound with the dihydric alcohol glycol.

PPG-1-PEG-9 lauryl glycol ether is used in cosmetic formulations. The mixture of substances acts as an emulsifier (surface-active substance which is used in cosmetic preparations as an auxiliary agent to combine two immiscible liquids - e.g. oil and water - to form an emulsion), and as a surfactant (washing-active substance; improves the even distribution of the products during application) and as a surfactant (washing-active substance; improves the even distribution of the products during application).
