Mechanical blockage, reduced productivity

The mechanism of antiperspinant action has not been fully estabHshed but probably is associated with blockage of ducts leading to the surface by protein denaturation by aluminum salts. The FDA has mandated that an antiperspinant product must reduce perspiration by at least 20% and has provided some guidelines for testing finished products. Some antiperspinant chemicals are Hsted in Table 14 (63).
