What does this ingredient do in an antiperspirant?
CosIng lists Propylene Carbonate with the functions "solvent" and "viscosity controlling".
Part of a system, not a label in isolation
It appears in sticks, creams and aerosols where the base needs a stable consistency. It does not reduce sweating; that is the job of the antiperspirant active.
Propylene Carbonate is not listed in the restrictive annexes of EU Regulation 1223/2009; the safety assessment applies to the finished formula.
Tolerance depends on the whole formula. If redness or stinging occurs, wash the product off and stop using it.
Propylene Carbonate is not the same as Propylene Glycol: they are different substances with different roles in a formula.
