Title: Improvements relating to disinfection
IPC: A01N31/00

Abstract: Disinfectant and fungicidal preparations comprise a mixture of two or more sulphonium compounds.  The preparations may be made by mixing two or more sulphonium compounds or by starting from mixed parent materials such as naturally occurring mixtures of fatty acids or fatty alcohols made therefrom by hydrogenation.  Liquid agents may be made by dissolving or dispersing two or more sulphonium compounds in water, or in an inert organic liquid, e.g. an alcohol, hydrocarbon or chlorine substitution product of a hydrocarbon.  The sulphonium compounds may also be mixed with indifferent solids, e.g. a soluble salt such as sodium sulphate or with bolus, talc, kieselguhr to produce dry powders.  The disinfectant agents may be used for the preservation of preparations containing proteins or starch or for the preservation of cosmetics.  Compounds containing radicals derived from fatty acids or alcohols of from 10 to 20 carbon atoms are particularly suitable, e.g. dodecyl-benzylmethyl-sulphonium methosulphate obtainable from dodecyl-benzyl-thioether and dimethyl sulphate and the corresponding tetradecyl, cetyl or octadecyl derivatives; dodecyl-paratolyl-methyl-sulphonium methosulphate obtainable from dodecyl-para-tolyl-thioether and dimethyl sulphate; dodecyl-dimethyl-sulphonium para-toluene sulphonate and higher derivatives obtainable from dodecyl-mercaptan and corresponding higher mercaptans and 2 mols of para-toluene-sulphonic acid methyl ester; di-decyl-methyl-sulphonium-methosulphate obtainable from didecyl-thioether and dimethyl sulphate.  The groups contained in the sulphonium chains may be of varied nature and may be substituted or interrupted.  Examples describe the disinfection of a solution of proteins, the preparation of an ointment having a petroleum jelly base and the preparation of aqueous disinfectant solutions, the active ingredients in each case being mixtures of sulphonium compounds having long chain alkyl radicals and in addition radicals such as methyl, phenyl, benzyl, tolyl.ALSO:Disinfectant and fungicidal preparations comprise a mixture of two or more sulphonium compounds.
