What does this ingredient do in an antiperspirant?

CosIng lists Trehalose with the functions humectant and moisturising.

Part of a system, not a label in isolation

In antiperspirants and deodorants, trehalose belongs to the skin care part of the base. It does not enhance the antiperspirant active or reduce sweating.

Regulatory and scientific context

Trehalose is not listed in the restrictive annexes of EU Regulation 1223/2009; the safety assessment applies to the finished formula.

What sensitive skin should consider

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

Do not confuse with

Trehalose is not the same as Glycerin: both hold water, but they are different substances.
