What does this ingredient do in an antiperspirant?
According to CosIng, it is an ester of starch with sodium octenylsuccinate. Its functions are absorbent, emulsion stabilising and viscosity controlling.
Part of a system, not a label in isolation
In creams and sticks it helps absorb moisture and keep a stable consistency. It does not reduce sweating.
Sodium Starch Octenylsuccinate 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; an individual reaction to the finished formula is still possible.
Sodium Starch Octenylsuccinate is not the same as Aluminum Starch Octenylsuccinate: they are different salts (sodium and aluminum) with different functions in CosIng.
