Abstract

The present invention relates to the field of perfumery. More particularly, it concerns malodor masking compositions and/or ingredients, as well as method for counteracting or masking malodors and perfuming compositions having odor masking properties.

1 - 10 . (canceled) 
     
     
         11 . A method of reducing malodor, comprising treating a malodor source with a compound of formula (I) in an amount sufficient to inhibit the growth of at least one bacteria selected from the group consisting of  S. aureus, S. haemolyticus, M. morganii,  and  S. agalactiae,    
       
         
           
           
               
               
           
         
         wherein one R group is a hydrogen atom and the other is a hydrogen atom or a C 1-3  alkyl group; and 
         each carbon-carbon double bond of said compound, independently from each other, can be in a configuration Z or E or a mixture thereof. 
       
     
     
         12 . The method of  claim 11 , wherein both R's are a hydrogen atom. 
     
     
         13 . The method of  claim 11 , wherein the compound of formula (I) is selected from the group consisting of (4E,8E)-4,8-cyclododecadien-1-one, (4Z,8E)-4,8-cyclododecadien-1-one, (4E,8Z)-4,8-cyclododecadien-1-one, (4E,8E)-12methylcyclododeca-4,8-dienone, (4E,8Z)-12-methylcyclododeca-4,8-dienone, (4Z,8E)-12methylcyclododeca-4,8-dienone, 2-methylcyclododeca-4,8-dienone and mixtures thereof. 
     
     
         14 . The method of  claim 11 , wherein the compound of formula (I) is:
 4,8-cyclododecadien-1-one in the form of a mixture comprising about 99% w/w of (4E,8E)-4,8-cyclododecadien-1-one and about 1% w/w of the (4Z,8E)-4,8-cyclododecadien-1-one and (4E,8Z)-4,8-cyclododecadien-1-one stereoisomer; or   4,8-cyclododecadien-1-one in the form of a mixture comprising at least 90% w/w of (4E,8Z)-4,8-cyclododecadien-1-one and (4Z,8E)-4,8-cyclododecadien-1-one stereoisomers and about 5% w/w of the (4E,8E)-4,8-cyclododecadien-1-one stereoisomer.   
     
     
         15 . The method of  claim 11 , wherein the inhibition of the growth of at least one bacteria selected from the group consisting of  S. aureus, S. haemolyticus, M. morganii,  and  S. agalactiae,  is sufficient to modify, suppress, reduce, decrease or mask the sensory perception of a body, residential or pet malodor. 
     
     
         16 . The method of  claim 15 , wherein the malodor is selected from the group consisting of kitchen, bathroom, tobacco, pet, and body malodor. 
     
     
         17 . The method of  claim 11 , wherein the amount sufficient to inhibit the growth of at least one bacteria selected from the group consisting of  S. aureus, S. haemolyticus, M. morganii,  and  S. agalactiae  is from 300 to 3500 ppm.
