Patent number: 9073966Abstract: The present invention relates to a method for screening compounds having the ability to prevent, suppress or reduce malodor development on body surfaces. In particular, the method allows to efficiently screen for compound having the ability of preventing sweat malodor development caused by volatile sulfur compounds (VSCs). The present invention is based on the finding of the direct precursor of naturally VSCs, which is present in human sweat and which will be metabolized by Staphylococci to VSCs.Type: GrantFiled: May 30, 2012Date of Patent: July 7, 2015Assignee: Firmenich SAInventors: Christian Starkenmann, Anthony Clark, Myriam Troccaz, Yvan Niclass
