Ppg-5-buteth-7 (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, e.g. "PPG-5" has 5 propylene glycol molecular units.

Buteth(e) are polyoxyethylene ethers which can be formally derived from the structure of butyl alcohol (for comparison see: laurethe as polyoxyethylene ether of lauryl alcohol; steareth as polyoxyethylene ether of stearyl alcohol etc.). In the name of butethe, the numbering added means the average number of ethylene oxide units per mole. Buteth-7 is the INCI designation for a polyoxyethylene ether with 7 ethylene oxide units per mole. PPG-5-buteth-7 is used in cosmetic formulations. The mixture of substances acts as

Antistatic agent (reduces static charges by neutralising the electrical charge on the surface, e.g. of hair), combability aid (reduces or prevents tangling of the hair due to changes or damage on the hair surface, thus improving combability) and as an emulsifier (surfactant used in cosmetic preparations as an adjuvant to combine 2 immiscible liquids - e.g. oil and water - to form an emulsion).
