The present invention relates to the use of quaternary ammonium compounds in the remediation of microbial growth such as mold, funguses, and mildew.

Use of quaternary ammonium compounds in the remediation of mold, mildew, and funguses

This invention provides a process for producing a betaine/amine oxide mixture. This process comprises reacting, in a liquid medium, an alkali metal &ohgr;-halocarboxylate with a first tertiary amine of the formula R,R,N, wherein each R,group is a hydrocarbyl group which independently has from 1 to about 4 carbon atoms, and wherein the R,group is a hydrocarbyl group which has from about 8 to about 24 carbon atoms, to produce a betaine product solution. To the betaine product solution is added a second tertiary amine of the formula R,R,N, wherein each R,group is a hydrocarbyl group which independently has from 1 to about 4 carbon atoms, and wherein the R,group is a hydrocarbyl group which has from about 8 to about 24 carbon atoms, to produce an amine/betaine mixture. The first and second tertiary amines can be separate portions of the same amine. Preferably, however, the first and second tertiary amines differ from each other. In a carbon dioxide atmosphere, the amine/betaine mixture is mixed with hydrogen peroxide to yield a betaine/amine oxide mixture.

Dishes are cleaned by washing them with a cleaning implement which has been charged with the detergent in a solid block made from a formulation having a water-soluble alkali metal salt content of 15-60% by weight and a surfactant content of 10-70% by weight, said surfactant comprising 15-100% by weight of at least one amine oxide corresponding to the formula RR'R'NO .multidot.nH.sub.2 O in which R and R' are independently selected from methyl, ethyl, and 2-hydroxyethyl, R' is a primary alkyl group containing 12-16 carbons, and n represents 0, 1, or 2.

Dish-washing method

A quaternary ammonium compound is combined with a water-soluble anionic surfactant having a hydrophile/lipophile balance (HLB) of 14 or above to form a biocidal/surfactant composition in which the amount of (ii) is up to 50 wt % of the total weight of these components. In the presence of water or other suitable aqueous media, such compositions appear to form a soluble charge complex. But whatever actually happens in the aqueous medium, the surfactant properties of the quaternary ammonium compound are improved without jeopardizing or impairing its germicidal properties.

Biocidal surfactant compositions and their use

Improved results are obtained in the no-rub cleaning of hard surfaces when the cleaner used in the process is an aqueous solution of (A) about 40-50% by weight of a nonionic surfactant mixture of an alcohol ethoxylate and a C.sub.8-16 alkyldimethylamine oxide in a weight ratio of about 5-15/1 and (B) correspondingly, about 60-50% by weight of one or more nitrogenous builders.
