What does this ingredient do in an antiperspirant?
A purified solid paraffin with a fine crystalline structure, a petroleum wax. Its INCI functions are viscosity controlling, emulsion stabilizing, binding and bulking.
Part of a system, not a label in isolation
In sticks it helps the bar hold its shape and release product evenly. It does not reduce sweat.
The CIR found Microcrystalline Wax safe in the present practices of use (1984 assessment of fossil and synthetic waxes, conclusion reaffirmed in 2003).
It is used as a structuring ingredient; an individual reaction to the finished product is possible.
Not the same INCI as Hydrogenated Microcrystalline Wax. On European labels the same wax may appear as Cera Microcristallina.
