  • Patent number: 8623340
    Abstract: The present invention relates to antimicrobially active ?-cyclohexylalkan-1-oles of the following formula (I), to a method for producing said compounds and to the use thereof as antimicrobial agents for treating body odor, wherein R1 to R6 independently of one another denote hydrogen or a linear or branched alkyl radical having 1 to 12 carbon atoms, Ra and Rb independently of one another denote hydrogen, a linear or branched alkyl radical having 1 to 6 carbon atoms or a linear or branched alkoxy radical having 1 to 4 carbon atoms, and x is 0 or 1, wherein preferably the total number of carbon atoms in R1 to R6 is 18 or less.
    Type: Grant
    Filed: April 28, 2009
    Date of Patent: January 7, 2014
    Assignee: Symrise AG

  • Patent number: 6495152
    Abstract: A class of biopolymer including sulfur in the form of a thioester in the polymer backbone or a thioether in the polymer side chains has been developed. These are preferably produced by fermentation of bacteria with appropriate sulfur containing substrates, which are incorporated by a broad spectrum polyhydroxyalkanoate (“PHA”) polymerase. The sulfur-containing PHAs allow various applications and uses in industry. Representative embodiments of the applications of the sulfur-containing PHAs include their uses in the packaging industry, medicine, pharmacy, agriculture or food industry, as active agents or as coatings, packaging, or carriers.
