Abstract: An antimicrobial water soluble substrate is formed by combining a silane, generically a quaternary ammonium salt form of a silane, with a water soluble powder selected from the group consisting of antiperspirant salts, starches, clays, and sugars. When the substrate is dissolved in water, the silane is released for redeposition.

Abstract: Clear stable micellar solutions comprising:(a) a silane represented by the formulae:X.sub.4-n Si(RNH.sub.a R'.sub.b Y.sub.c).sub.n (i)where X denotes an alkoxy radical with 1 to 6 carbon atoms, or an alkoxyalkoxy radical with 2 to 8 carbon atoms, or an alkyl radical with 1 to 6 carbon atoms;y denotes an acid anion;n is 1, 2 or 3;R denotes a divalent hydrocarbon radical with 1 to 6 carbon atoms;R' denotes alkyl radicals with 1 to 22 carbon atoms; saturated hydrocarbon radicals containing nitrogen, or unsaturated hydrocarbon radicals containing nitrogen;a is 0, 1 or 2;b is 0, 1, 2, or 3;c is 0 or 1; the sum of a+b is 2 or 3 and when the sum of a and b is 3, c is 1, otherwise c is O;X.sub.4-n Si(RPR".sub.3 Y).sub.
