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-5" this is 5 propylene glycol molecular units. "lanolate" refers to PEG-esters of fatty acids which are extracted from lanolin.
PPG-5 lanolate is used in cosmetic formulations. The mixture of substances acts as an emulsifier (a surface-active substance used in cosmetic products as an additive to combine 2 immiscible liquids - e.g. oil and water - to form an emulsion) and as emollient (makes the skin smooth and supple).
