What does this ingredient do in an antiperspirant?
Octane-1,2-diol. CosIng lists it as a skin conditioning agent and emollient, a hair conditioning agent and a deodorant ingredient; the CIR notes that caprylyl glycol is also used as a cosmetic preservative.
Part of a system, not a label in isolation
In roll-ons, creams and gels it usually acts as a supporting care and stability ingredient. It does not reduce sweating.
The CIR reviewed 1,2-glycols, including Caprylyl Glycol, and in 2012 concluded that they are safe in the present practices of use and concentration; the CIR summary table lists concentrations of 0.00003–5%.
It is generally well tolerated; on irritated skin a reaction to the finished formula is possible.
Not the same as Caprylic/Capric Triglyceride or Glyceryl Caprylate: it is a glycol, not an oil or a glycerol ester.
