SGS Launches a New Service to Test the Efficacy of Foot Antiperspirant Products

SGS, the world’s leading
inspection, verification, testing and certification company, has launched a
bespoke new testing service to enable manufacturers of antiperspirants for feet
to test and certify the efficacy of their products.

National and international
authorities require that efficacy claims of cosmetic products should be
substantiated scientifically. However, d
espite an increasing number of foot-specific antiperspirants
entering the
and personal care markets, the industry has no
standard or norm equipped to test products directly at
the site of action, i.e. under the feet.

Dr. Ines Sellami, Lab Manager Cosmetic
Performance & Customer Service Consultant, SGS, said: “It became clear to
our testing laboratory specialists, when tasked with testing the efficacy of
foot antiperspirants, that not enough data exists to enable results from
products tested under the arms to be generally transferred to products used under
the feet.

“We realized that, to ensure robust
testing and enable consumers to have confidence in their purchases, we needed
to devise a scientifically supported test capable of measuring a product’s
effectiveness directly on the feet. We are very proud
to launch our new testing service which is available now.”

From its dedicated laboratory in Germany,
SGS is equipped to measure important skin-associated parameters such as skin
moisturization (Corneometer®), skin barrier integrity (Tewameter®),
wrinkle-reduction (PRIMOS®) or deodorant-efficacy (sniff-test).

To develop the new test, SGS used
‘FDA Guidelines for effectiveness testing of OTC antiperspirant drug products’
as the basis. Tested with volunteers, it is based on the same principles:
selection of test subjects, preconditioning phase, application amount,
implementation (gravimetry) and evaluation (Wilcoxon test, Z-Score).
