Efficacy of a deodorant and its components: Triethylcitrate and perfume
Andreas Lukacs , Hans Christian Korting , Otto Braun-Falco , Klaus Stanzl

ABSTRACT

Synopsis

Both perfumes and acids are considered as potential active ingredients of deodorants. In a double-blind controlled trial, deodorant preparations containing perfume and triethylcitrate in a 60% ethanol base were compared to preparations lacking either perfume or triethylcitrate, and to a placebo preparation. The degree of offensive smell of the axillae of 30 healthy volunteers was assessed by sniffing. The skin surface pH and the bacterial flora were examined at the same time.

The total preparation with both perfume and triethylcitrate was effective compared to the placebo with respect to the reduction of malodor. Moreover, the perfume component indicated efficacy in this respect. But triethylcitrate was not effective in the present formula. A marked influence on the skin surface pH could not be shown with any of the preparations. Thus, alterations of the bacterial flora if demonstrated at all could not be traced to a change in skin surface pH.
