What does this ingredient do in an antiperspirant?
According to CosIng, it is obtained by acid or enzyme hydrolysis of corn starch and consists primarily of glucose, maltose and maltodextrins. Its functions are binding, humectant, skin conditioning and viscosity controlling.
Part of a system, not a label in isolation
In deodorants and antiperspirants it belongs to the skin care part of the base and supports its texture. It does not reduce sweating.
Hydrolyzed Corn Starch is not listed in the restrictive annexes of EU Regulation 1223/2009; the safety assessment applies to the finished formula.
It is generally well tolerated; a reaction to the finished formula is still possible.
Hydrolyzed Corn Starch is not the same as Corn Starch Modified: the modified starch acts as a dry absorbent, while the hydrolyzed one acts as a humectant.
