Patent ID: 7638118

Claim:
A method of imparting a malodor neutralizing effects to a substrate comprising contacting the substrate with the aminoalkyl substituted fumarate of formula (I) wherein n is 1 or 2; Z is —OR 2 or —Y—(R—NR 5 R 6 ) n ; R is linear or branched C 2 -C 9 alkyl, linear or branched C 3 -C 18 alkoxyalkyl, phenyl, linear or branched C 7 -C 15 phenoxyalkyl, or linear or branched C 8 -C 16 benzoyloxyalkyl; R 2 is linear or branched C 1 -C 8 alkyl, C 3 -C 12 cycloalkyl or C 4 -C 13 alkylcycloalkyl wherein the cycloalkyl ring is optionally substituted with C 1 -C 6 alkyl; or R 2 is linear or branched C 1 -C 8 alkyl containing at least one oxygen atom, C 3 -C 12 cycloalkyl containing at least one oxygen atom and wherein the cycloalkyl ring is optionally substituted with C 1 -C 6 alkyl, or C 4 -C 13 alkylcycloalkyl containing at least one oxygen atom and wherein the cycloalkyl ring is optionally substituted with C 1 -C 6 alkyl; R 3 and R 5 are independently hydrogen, phenyl, linear or branched C 1 -C 10 alkyl, or linear or branched C 1 -C 10 alkyl containing at least one oxygen atom; R 4 and R 6 are independently linear or branched C 1 -C 10 alkyl, or linear or branched C 1 -C 10 alkyl containing at least one oxygen atom; or R 3 and R 4 , or R 5 and R 6 are forming together with the nitrogen atom to which they are attached an aliphatic or aromatic heterocyclic ring system having 3 to 6 ring atoms; the ring system can optionally contain one oxygen atom or an additional nitrogen atom; and the ring system can optionally bear one or more linear or branched C 1 -C 6 alkyl groups, C 5 -C 6 cycloalkyl groups, or C 5 -C 6 aryl groups; and a) when n is 1; Y is oxygen or NR 1 wherein R 1 is hydrogen, linear of branched C 1 -C 8 alkyl, C 3 -C 12 cycloalkyl or alkylcycloalkyl; or R 1 is linear of branched C 1 -C 8 alkyl substituted with oxygen atoms, C 3 -C 12 cycloalkyl substituted with oxygen atoms, or alkylcycloalkyl substituted with oxygen atoms; and b) when n is 2, Y is nitrogen.
