ANTI-MICROBIAL WIPES

摘要

The present invention provides an anti-microbial wipe comprising a substrate comprising from 1 to 100% by weight of a cellulosic material and incorporating a composition comprising (i) an anti-microbial component; (ii) a non-ionic surfactant; (iii) a polar solvent; and optionally (iv) a hydrophobic material; wherein the anti-microbial component (i) comprises (a) at least one quaternary ammonium compound of formula (A) R1R2R3R4N+X-, wherein R1, R2, R3 and R4 represent, independently a substituted or unsubstituted and/or straight chain or branched and/or interrupted or uninterrupted alkyl, aryl, alkylaryl, arylalkyl, cycloalkyl, heterocyclyl or alkenyl group, and wherein the total number of carbon atoms in the groups R1, R2, R3 and R4 is at least 4; wherein the substituents for the groups R1, R2, R3 and R4 are selected from the group consisting of alkyl, substituted alkyl, alkenyl, substituted alkenyl, heterocyclyl, substituted heterocyclyl, cycloalkyl, substituted cycloalkyl, aryl, substituted aryl, alkylaryl, substituted alkylaryl, arylalkyl, substituted arylalkyl, F, Cl, Br, I, -OR', -NR'R", -CF3, -CN, -NO2, -C2R', - SR', -N3, -C(=O)NR'R", -NR'C(=O) R", -C(=O)R', -C(=O)OR', -OC(=O)R', -O(CR'R")rC(=O)R' -O(CR'R")rNR"C(=O)R', -O(CR'R")rNR"SO2R', -OC(=O)NR'R", -NR'C(=O)OR", -SO2R', - SO2NR'R", and -NR'SO2R"; wherein R' and R" are individually hydrogen, C1-C8 alkyl, cycloalkyl, heterocyclyl, aryl, or arylalkyl, and r is an integer from 1 to 6, or R' and R" together form a cyclic functionality; wherein the term "substituted" as applied to alkyl, alkenyl, heterocyclyl, cycloalkyl, aryl, alkylaryl and arylalkyl refers to the substituents described above, starting with F and ending with -NR'SO2R"; and wherein X- is halide or sulphonate; and optionally (b) one or more additional anti-microbial agents, and wherein the composition is substantially free of anionic surfactant.
