Antimicrobial rinse cycle additive
First Claim
1. A rinse cycle fabric laundering additive composition comprising a mixture of at least one nonsilicon organic quaternary ammonium compound, and at least one organosilicon quaternary ammonium compound, the organosilicon quaternary ammonium compound being an organosilane having the formula selected from the group consisting of ##STR11## wherein, in each formula, Y is R or RO where each R is an alkyl radical of 1 to 4 carbon atoms or hydrogen;
- a has a value of 0, 1 or 2;
R'"'"' is a methyl or ethyl radical;
R" is an alkylene group of 1 to 4 carbon atoms;
R'"'"'", R"" and Rv are each independently selected from a group consisting of alkyl radicals of 1 to 18 carbon atoms, --CH2 C6 H5, --CH2 CH2 OH, --CH2 OH, and --(CH2)x NHC(O)Rvi, wherein x has a value of from 2 to 10 and Rvi is a perfluoroalkyl radical having from 1 to 12 carbon atoms; and
X is chloride, bromide, fluoride, iodide, acetate or tosylate.

Abstract
A method of treating fabrics in order to eliminate odor caused by microbial growth by adding an antibacterially effective amount of an organosilicon quaternary ammonium compound to the rinse cycle of a textile laundering operation containing the fabrics in order to destroy bacteria and fungi. The organosilicon quaternary ammonium compound is the silane 3-(trimethoxysilyl) propyldimethyloctadecyl ammonium chloride of the formula ##STR1##
