Ppg-4 myristyl ether (inci)

PPG-4 Myristyl Ether is a substance used in cosmetic formulations where it acts as an emollient (makes the skin smooth and supple) and emulsifier (a surfactant used in cosmetic preparations as an excipient to combine 2 immiscible liquids - e.g. oil and water - into one emulsion).

"PPG" means a PPG (polypropylene glycol) derivative. The number after "PPG-" (in case of mixed PEG/PPG derivatives the second number) indicates the average number of molecular units -CH2-CH2-CH2-O-. This ingredient contains myristyl alcohol (tetradecanol) as the alcoholic component. "Ether" means a condensation product of two alcohols.
