What does this ingredient do in an antiperspirant?
CosIng lists Pentylene Glycol with the functions skin conditioning and solvent. CIR notes that pentylene glycol is also used as a preservative in cosmetics.
Part of a system, not a label in isolation
In roll-ons and gels it helps dissolve the components of the base and keep it stable. It does not reduce sweating.
CIR assessed 1,2-glycols, including pentylene glycol, and concluded that they are safe in the present practices of use and concentration.
It is generally well tolerated; on irritated skin a reaction to the finished formula is possible.
Pentylene Glycol is not the same as Propylene Glycol or Butylene Glycol: they are related glycols with different chain lengths and properties.
