A high stability formulation in the form of an aqueous mixture is disclosed. The formulation containing a quaternary ammonium organosilane hydrolysate includes the structure A(CH.sub.3).sub.2N.sup.+(CH.sub.2).sub.3Si(OZ).sub.3-n(OH).sub.n, wherein “A” is a saturated or unsaturated aliphatic chain having 12 to 18 carbons, “n” is an integer ranging from 0 to 2, “Z” is methyl or ethyl. A method to obtain the formulation includes a first reaction in which the tertiary amine group having the structure A(CH.sub.3).sub.2N is quaternized by alkylation with a reactant having the structure (CH.sub.2).sub.3Si(OR).sub.3X, wherein X is halogen. Then, a second reaction is performed in which the tertiary amine remaining unreacted in the first reaction is quaternized with one or more supplementary reactants selected from benzyl chloride, benzyl bromide, benzyl iodide, vinyl benzyl chloride, vinyl benzyl bromide, vinyl benzyl iodide, epichlorohydrin, epibromohydrin, epiiodohydrin, chloroethanoic acid, bromoethanoic acid, iodoethanoic acid, and sultones, preferably 1,3-propane sultone or 1,4-butane sultone.
