Patent ID: 6936735

Claim:
A compound of Formula I wherein one of R and R 1 is hydrogen or linear or branched C 1 to C 10 alkyl, or linear or branched C 1 to C 10 alkoxy and the other is independently linear or branched C 1 to C 10 alkyl, or linear or branched C 1 to C 10 alkoxy; R 2 is linear or branched C 1 to C 10 alkyl, or linear or branched C 1 to C 10 alkoxy; R 3 is selected from the group consisting of COCH 3 , CO 2 R 7 , CONH 2 , CON(R 8 ) 2 , COX(CH 2 )n-N—(R 4 )(R 5 )(R 6 ), and the quaternized salt form of the formula COX(CH 2 )n-N—(R 4 )(R 5 )(R 6 ) + Y − ; X is O or NH; n is an integer of 1 to 5; Y is an anion; R 4 , R 5 and R 6 are independently linear or branched C 1 to C 30 alkyl; and R 7 and R 8 are independently hydrogen or linear or branched C 1 -C 30 alkyl.
