What does this ingredient do in an antiperspirant?
According to CosIng, Kaolin is a naturally occurring substance (CI 77004) with the functions abrasive, absorbent, anticaking, bulking, colorant and opacifying.
Part of a system, not a label in isolation
In deodorants and powders, kaolin helps absorb moisture on the skin surface and gives a matte, dry texture. It does not reduce sweat production.
CIR assessed kaolin together with other silicates and clays and concluded that they are safe as currently used in cosmetics. As the colorant CI 77004, kaolin is listed in Annex IV of EU Regulation 1223/2009.
It is generally well tolerated. CIR notes that the toxicity of clays is mainly linked to inhaling the dust, so the dry powder should not be inhaled.
Kaolin is not the same as Talc: CIR assesses talc separately because of its distinct crystal structure. The aluminum in kaolin does not make it an antiperspirant active.
