Zusammenfassung:A method of assessing efficacy of an amine-free antiperspirant is provided. The method comprises (a) contacting a textile with skin having sweat, wherein the sweat is formed on the skin having the antiperspirant thereon, whereby the sweat is transferred from the skin onto the textile, (b) contacting the textile from step (a) with an effective amount of a solution for generating a purple color on the textile, wherein the solution comprises ninhydrin and a solvent, whereby a purple color is generated on the textile, and (c) determining an intensity of the purple color on the textile, wherein a high intensity of the purple color indicates a low efficacy of the antiperspirant.
