         6 . The malodor control composition of  claim 1  wherein said at least one volatile aldehydes is present in an amount from about 1% to about 10%, by weight of said malodor control composition. 
     
     
         7 . The malodor control composition of  claim 1  wherein said at least one volatile aldehyde is present in an amount from about 1% to about 5%, by weight of said malodor control composition, and said acid catalyst is present in an amount of about 0.4% to about 1.5%, by weight of said malodor control composition. 
     
     
         8 . The malodor control composition of  claim 1  wherein said at least one volatile aldehyde comprises a mixture of volatile aldehydes selected from the group consisting of Accord A, Accord B, Accord C, and mixtures thereof. 
     
     
         9 . The malodor control composition of  claim 1  wherein said at least one volatile aldehyde comprises a mixture of volatile aldehydes, said mixture comprising about 1% to about 10% of Accord A, by weight of said malodor control composition. 
     
     
         10 . The malodor control composition of  claim 1  wherein said acid catalyst is present in an amount from about 0.1% to about 0.4%, by weight of said malodor control composition. 
     
     
         11 . The malodor control composition of  claim 1  wherein said acid catalyst is present in an amount of about 0.4%, by weight of said malodor control composition. 
     
     
         12 . The malodor control composition of  claim 1  wherein said composition has a pH of about 4 to about 6.5. 
     
     
         13 . The malodor control composition of  claim 1  further comprising an ingredient selected from the group consisting of: odor masking agents, odor blocking agents, diluents, and mixtures thereof. 
     
     
         14 . A malodor control composition comprising:
 at least one volatile aldehyde; and   about 0.05% to about 1.5%, by weight of said malodor control composition, of an acid catalyst having a vapor pressure of about 0.01 torr to about 2 torr at 25° C.   
     
     
         15 . The malodor control composition of  claim 14  wherein said acid catalyst is present in an amount from about 0.4% to about 1.5%, by weight of said malodor control composition. 
     
     
         16 . The malodor control composition of  claim 14  wherein said at least one volatile aldehyde is selected from the group consisting of 4,8-dimethyl-4,9-decadienal, o-anisaldehyde, and mixtures thereof.
