What does this ingredient do in an antiperspirant?
According to CosIng, it has four functions: astringent, antiperspirant, buffering (keeps the pH stable) and deodorant. In cosmetics it is found mainly in antiperspirants.
Part of a system, not a label in isolation
In the catalog it appears alongside aluminum chloride in a long-lasting product where the chloride is the declared active. The effect of such a formula depends on the whole combination, the concentrations and the base, not on one ingredient.
Aluminum lactate is not on the FDA M019 list of antiperspirant actives, so in the US it is not a recognized active for over-the-counter antiperspirants. In the EU it falls under the general SCCS assessment: aluminum compounds are safe in cosmetics within the limits assessed in opinion SCCS/1662/23.
The sources give no specific irritation data for this salt. In formulas with aluminum chloride and alcohol, those ingredients largely determine the irritation potential.
It is not the same as Aluminum Chloride or Aluminum Chlorohydrate: both of those salts are on the FDA list, aluminum lactate is not. Nor should it be confused with lactic acid or lactic acid esters such as C12-13 Alkyl Lactate.
