What does this ingredient do in an antiperspirant?
An ether of butyl alcohol and polypropylene glycol with an average of 14 propylene oxide units. CosIng lists skin- and hair-conditioning functions; the CIR notes that many ethers in this group also act as solvents.
Part of a system, not a label in isolation
In the catalog it appears in sticks, aerosols and sprays, including as the only inactive ingredient next to an aluminum salt. According to the CIR, deodorants use it at up to 17.5%; it does not reduce sweat by itself.
The CIR (2022) found butyl polyoxyalkylene ethers, including PPG-14 Butyl Ether, safe in the present practices of use when formulated to be non-irritating.
In a human repeat insult patch test (HRIPT), undiluted PPG-14 Butyl Ether was not a sensitizer. An individual reaction to the finished product is still possible.
Do not confuse it with PPG-15 Stearyl Ether: PPG-14 Butyl Ether has a short butyl tail instead of a long stearyl one, and CosIng assigns them different functions.
