An ether of stearyl alcohol and polypropylene glycol with an average of 15 propylene oxide units. CosIng lists it as an emollient.

Part of a system, not a label in isolation

It is the most frequent ingredient of this group in the catalog, mostly in roll-ons. According to the CIR, underarm deodorants have used it at 3–4.4%; it does not reduce sweating.

Regulatory and scientific context

The CIR found PPG-15 Stearyl Ether safe in 2001 and confirmed that conclusion in a 2023 re-review; the reported use concentration is up to 18%. The panel cautioned that it may enhance skin penetration of other ingredients, which formulators take into account.

What sensitive skin should consider

In the 2001 report the undiluted substance was slightly irritating to rabbit skin; products contain it at much lower concentrations. An individual reaction to the finished formula is possible.

Do not confuse with

Do not confuse it with Stearyl Alcohol or steareths: here propylene glycol (PPG) units, not ethylene glycol (PEG) units, are attached to stearyl alcohol.
