Abstract

The present invention provides a novel compound for counteracting amine-based malodor in consumer, industrial and textile products.

What is claimed is: 
     
         1 . A consumer, industrial or textile product comprising a malodor counteractant compound comprising a α-keto moiety covalently attached to
 (a) polymer comprising an olefin, polysaccharide, polyamine, polyacrylate, polyalkylene oxide with OH or NH 2  end groups, or block or random copolymer thereof; 
 (b) an oligomer comprising an oligosaccharide or oligomeric alkane; 
 (c) a surfactant comprising diblock or triblock copolymers of ethylene oxide, propylene oxide or butylene oxide, or poloxamine; or 
 (d) a solid surface comprising a silica or clay surface, 
 wherein the α-keto moiety comprises a ketone which is capable of reacting with malodors. 
 
     
     
         2 . The consumer, industrial or textile product of  claim 1 , wherein the α-keto moiety comprises levulinic acid, acetoacetic acid, pyruvic acid, α-ketoglutaric acid, α-ketobutyric acid, α-ketoisocaproic acid, or α-ketovaleric acid. 
     
     
         3 . The consumer, industrial or textile product of  claim 1 , wherein the malodor counteractant compound has the structure: 
       
         
           
           
               
               
           
         
         wherein X represents O, N, or C; 
         wherein n represents an integer of 0 or greater; and 
         wherein R is
 (a) polymer comprising an olefin, polysaccharide, polyamine, polyacrylate, polyalkylene oxide with OH or NH 2  end groups, or block or random copolymer thereof; 
 (b) an oligomer comprising an oligosaccharide or oligomeric alkane; 
 (c) a surfactant comprising diblock or triblock copolymers of ethylene oxide, propylene oxide or butylene oxide, or poloxamine; or 
 (d) a solid surface comprising a silica or clay surface. 
 
       
     
     
         4 . The consumer, industrial or textile product of  claim 3 , wherein X is NH, n is an integer of 0 to 2, and R is a copolymer of ethylene oxide and propylene oxide. 
     
     
         5 . A method for producing a malodor counteractant compound comprising covalently attaching a α-keto moiety to
 (a) polymer comprising an olefin, polysaccharide, polyamine, polyacrylate, polyalkylene oxide with OH or NH 2  end groups, or block or random copolymer thereof; 
 (b) an oligomer comprising an oligosaccharide or oligomeric alkane; 
 (c) a surfactant; or 
 (d) a solid surface comprising a silica or clay surface. 
 
     
     
         6 . A malodor counteractant compound comprising an α-keto moiety covalently attached to:
 (a) a polymer comprising an olefin, polysaccharide, polyamine, polyacrylate, polyalkylene oxide with OH or NH 2  end groups, or block or random copolymer thereof; 
 (b) an oligomer comprising an oligosaccharide or oligomeric alkane; 
 (c) a surfactant comprising diblock or triblock copolymers of ethylene oxide, propylene oxide or butylene oxide, or poloxamine; or 
 (d) a solid surface comprising a silica or clay surface, wherein the α-keto moiety comprises a ketone which is capable of reacting with malodors. 
 
     
     
         7 . The malodor counteractant compound of  claim 6 , wherein the α-keto moiety comprises levulinic acid, acetoacetic acid, pyruvic acid, α-ketoglutaric acid, α-ketobutyric acid, α-ketoisocaproic acid, or α-ketovaleric acid. 
     
     
         8 . The malodor counteractant compound of  claim 6 , wherein the malodor counteractant compound has the structure: 
       
         
           
           
               
               
           
         
         wherein X represents O, N, or C; 
         wherein n represents an integer of 0 or greater; and 
         wherein R is a
 (a) polymer comprising an olefin, polysaccharide, polyamine, polyacrylate, polyalkylene oxide with OH or NH 2  end groups, or block or random copolymer thereof; 
 (b) an oligomer comprising an oligosaccharide or oligomeric alkane; 
 (c) a surfactant comprising diblock or triblock copolymers of ethylene oxide, propylene oxide or butylene oxide, or poloxamine; or 
 (d) a solid surface comprising a silica or clay surface. 
 
       
     
     
         9 . The malodor counteractant compound of  claim 8 , wherein X is NH, n is an integer of 0 to 2, and R is a copolymer of ethylene oxide and propylene oxide. 
     
     
         10 . A method for counteracting an amine-based malodor of a consumer, industrial or textile product or the surrounding environment thereof comprising the step of adding the malodor counteractant compound of  claim 6  to the product and reducing the presence of an amine-based malodor of the consumer, industrial or textile product.
