What does this ingredient do in an antiperspirant?
According to CosIng, talc is a powdered natural hydrous magnesium silicate. Its functions are absorbent, bulking, anticaking, slip modifier and skin protecting.
Part of a system, not a label in isolation
In sticks, powders and creams, talc gives a dry, smooth feel and reduces stickiness. It does not stop sweat; it only absorbs moisture on the surface.
Talc is listed in Annex III of EU Regulation 1223/2009. Powdery products for children under 3 must carry a warning to keep the powder away from the child's nose and mouth.
On the skin, talc is usually not irritating; loose powder should not be inhaled. An individual reaction to the finished formula is still possible.
Talc is not the same as Kaolin or Silica: they are different minerals. CIR assesses talc separately from other silicates because of its distinct crystal structure.
