Definitions

• the present invention relates to a bleaching and cleaning composition, and more in particular to a liquid thickened chlorine bleaching composition which is based on an aqueous solution of alkali metal hypochlorite.
• Aqueous solutions of an alkali metal hypochlorite are widely used as disinfectant cleaners for lavatory pans, urinals, drains and waste pipes, but may also be employed in the cleaning and bleaching of fabrics.
• present-day bleaching products based on the above thickening system contain the commercially available amineoxides derived from naturally occurring fatty acids such as coconut acids, lauric acid and myristic acid.
• the present invention provides a liquid thickened chlorine bleaching composition
• a liquid thickened chlorine bleaching composition comprising an aqueous alkali-metal hypochlorite solution which is thickened by means of a detergent-active mixture comprising a mono(C 8 -C 18 )-di(C 1 -C 3 ) alkylamine-oxide, characterized in that at least 20% by weight of the amineoxide component have C 16 -C 18 alkyl-groups.
• the thickening active system consists of at least two different detergent-active components, one of which comprises a trialkylamineoxide having two short chain C l -C 3 alkylgroups and a long chain C 8 -C 18 alkylgroup.
• a trialkylamineoxide having two short chain C l -C 3 alkylgroups and a long chain C 8 -C 18 alkylgroup In order to obtain the advantages of the present invention at least 20%, preferably 20 to 50%, and most preferably 30 to 50% by weight of the amineoxide should contain long chain alkylgroups having 16-18 carbon atoms. Higher proportions of amineoxide having C 18 alkyl groups have an increasing effect on the cloud point of the composition and in general allow a reduction of the amineoxide/co-active weight ratio. Accordingly it is preferred that in the C 16 -C 18 alkylamine-oxide fraction the amount of C 18 -alkyl exceeds that of C 16 -alkyl.
• the second detergent active component present in the thickener can be an alkalimetal soap or mixture thereof according to British Patent Specification 1 329 086, alkalimetal acylsarcosinates or -alkyltaurides according to British Patent Specification 1 466 560 or sugar esters according to Dutch Patent Application 7 605 328, or mixtures thereof.
• Alkali metal C 10 -C 18 alkylether (containing 1-10 moles of ethylene- and/or propyleneoxide) sulphates can also be used.
• the mixtures of trialkylamineoxides and alkali metal soaps of fully saturated C a -C 18 fatty acids are preferred.
• the thickening active system is used in an amount of 0.3-5%, preferably 0.5-3% by weight of the final composition.
• the composition may be thickened to a wide range of viscosities, preferably from about 10 to 250 cS or even from about 30 to 150 cS as measured with a U-tube viscosimeter at a temperature of 25°C.
• the stability of the composition may be improved by the addition of a small amount, in the order of 0.1-15%, of alkaline agents, such as for example sodium carbonate, trisodium orthophosphate, sodium hydroxide and the like.
• alkaline agents such as for example sodium carbonate, trisodium orthophosphate, sodium hydroxide and the like.
• the alkali metal hypochlorite will generally be present in the composition in an amount sufficient to provide from 1 to 15%, preferably 2 to 11% and most preferably 5 to 10% by weight of available chlorine on the basis of the total weight of the composition.
• alkali metal hypochlorites are preferred, other chlorine compounds which yield the hypochlorite ion in alkaline aqueous solution may also be used, e.g. calcium and magnesium hypochlorite, alkali metal dichloro-isocyanurate, chloramines and the like.
• thickened chlorine bleaching compositions according to the invention may contain small amounts of conventional additives, such as hypochlorite-soluble and stable colorants and perfumes. Small amounts of insoluble solid particles are also tolerable.
• compositions of the invention can be prepared in conventional ways, for example as described in British Patent Specification 1 329 086.
• compositions of the invention are useful for all bleaching purposes, especially for bleaching hard surfaces, such as toilets, tiles, floors, kitchen sinks, etc., where by their thickened nature they adhere longer to the surface than non-thickened bleaching compositions.
