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

Publication number: 20130295229Abstract: The present invention relates to the use of 3-mercaptoheptyl carboxylate in the form of any one of its stereoisomers or in the form of a mixture thereof. The compounds of the invention are valuable flavoring ingredients capable of imparting fruity, citrus and/or teas aftertaste with a well-balanced long-lastingness. The present invention also concerns the compositions or articles containing the compound.Type: ApplicationFiled: July 11, 2013Publication date: November 7, 2013Inventors: Sina Dorothea Escher, Yvan Niclass, Lionel Saudan
