What does this ingredient do in an antiperspirant?
A thin, liquid ester of myristic acid and isopropyl alcohol. Its INCI functions are emollient, binder and fragrance excipient.
Part of a system, not a label in isolation
It is also used in deodorants: the CIR cited data on Isopropyl Myristate in deodorant formulations. In the formula it handles texture, not sweat reduction.
The CIR assessed Isopropyl Myristate with other alkyl esters and found them safe in the present practices of use when formulated to be non-irritating.
If a contact allergy is suspected, a dermatologist can include this substance in a patch test.
It is not isopropyl alcohol or an alcohol base: Isopropyl Myristate is an oily ester.
