What does this ingredient do in an antiperspirant?

CosIng lists Propanediol (1,3-propanediol) with the functions solvent and viscosity controlling.

Part of a system, not a label in isolation

In roll-ons and gels it dissolves skin care ingredients and extracts and affects the texture. It does not reduce sweating.

Regulatory and scientific context

CIR assessed 10 alkane diols and found seven of them, including Propanediol, safe in the present practices of use and concentration; data were insufficient only for 1,4-butanediol, 2,3-butanediol and octanediol.

What sensitive skin should consider

It is generally well tolerated; an individual reaction to the finished formula is still possible.

Do not confuse with

Propanediol is not the same as Propylene Glycol: they are isomers (1,3- and 1,2-propanediol) with different properties and are listed under different names.
