Classification: CPC C  A  D | IPC A  C

Claim 1:
2. The fabric care composition according to claim 1, wherein the quaternary ammonium ester compound comprises compounds according to Formula (I):

{R2(4-m)—N+—[X—Y—R1]m}A−  Formula (I)

wherein:
m is 1, 2 or 3, with provisos that
in a given molecule, the value of each m is identical, and
for at least some of the compounds according to Formula (I), m is 3 (i.e., a triester);

each R1, which independently comprises from 13 to 22 carbon atoms, is independently a linear hydrocarbyl or branched hydrocarbyl group;
each R2 is independently a C1-C3 alkyl or hydroxyalkyl group and/or each R2 is selected from methyl, ethyl, propyl, hydroxyethyl, 2-hydroxypropyl, 1-methyl-2-hydroxyethyl, poly(C2-C3 alkoxy), polyethoxy, or benzyl;
each X is independently —(CH2)n-, —CH2—CH(CH3)— or —CH(CH3)—CH2—, where each n is independently 1, 2, 3 or 4;

each Y is independently —O—(O)C— or —C(O)—O—; and
A− is independently selected from the group consisting of chloride, bromide, methyl sulfate, ethyl sulfate, sulfate, and nitrate.
