Definitions

  • This invention relates to detergent powders, more particularly to alkaline detergent powders having a bactericidal action.
  • Alkaline detergent powders are commonly used on the industrial scale, particularly for purposes such as machine dish-washing. These powders often contain a major proportion of an alkaline inorganic detergent salt such as silicate or phosphate as the chief detergent constituent. Frequently, it is convenient to incorporate one or more organic soapless detergents in such a powder.
  • an alkaline inorganic detergent salt such as silicate or phosphate
  • the present invention provides, therefore, a detergent powder which comprises a major proportion of an alkaline inorganic detergent salt, a minor proportion of an organic soapless detergent, a minor proportion of an inorganic hypochlorite compound and a minor proportion of a compound of the general formula or an alkali metal salt thereof, where R is OH, O-alkyl of 1-18 carbon atoms, NH NH-alkyl of 1-18 carbon atoms, Cl, Br or an alkyl group of 1-18 carbon atoms, Ar is a benzene ring, X is hydrogen, chlorine, or an alkyl group of 1-5 carbon atoms, and Y is hydrogen or chlorine, and the group may be ortho or para to the group R.
  • the preferred alkaline inorganic detergent salts for use in the powders of the invention are the alkali metal silicates, more especially sodium rnetasilicate.
  • Alkali metal phosphates can also be used.
  • the phosphates may be condensed phosphates or orthophosphates or mixtures of these.
  • Suitable condensed phosphates are the tripolyphosphates such as pentasodium tripolyphosphate, Na P O the pyrophosphates such as tetrasodium pyrophosphate, Na P and the hexametaphosphates, such as sodium hexametaphosphate, (NaPO
  • Other alkaline inorganic salts which may be used include the alkali metal carbonates, particularly sodium carbonate, and the alkali metal borates.
  • Organic soapless detergents which may be incorporated in the powders of the invention include anionic detergents such as salts of alkyl sulphuric acids and of organic sulphonic acids having detergent properties. Examples are sodium lauryl sulphate and the dodecyl benzene sulphonates. It is preferred to use nonionic soapless detergents such as the condensation products of alkyl phenols with condensation product of p-tert-octyl cresol with ethylene oxide containing about 8-10 moles of ethylene oxide is particularly suitable. Other nonionic soapless detergents which may be incorporated include the higher polyethylene glycols and polyoxyethylene esters such as polyoxyethylene sorbitan monostearate.
  • the inorganic hypochlorite compounds of the invention must be sufliciently stable not to decompose in the alkaline powders in the presence of the organic bactericidal chlorocompound but, on the other hand, must liberate chlorine in aqueous solution at a suitable rate when used for dishwashing purposes.
  • the preferred compounds are the solid alkali metal hypochlorite compounds.
  • the term solid alkali metal hypochlorite compound is taken to include those compounds which contain combined hypochlorite but in which the hypochlorite may not be present in stoichiometric proportions, such as chlorinated trisodium phosphate. Chlorinated trisodium posphate is the preferred hypochlorite compound.
  • chlorinated trisodium phosphate is meant the composition consisting of trisodium phosphate and sodium hypochlorite intimately associated in a crystalline form, which may be prepared as described in United States specification No. 1,555,474. Generally, the available chlorine content of chlorinated trisodium phosphate is between 1 and 5% but compositions containing higher amounts of available chlorine (6% or more) are particularly effective. Lithium hypochlorite may also be employed.
  • the sulphonamide compounds for use according to the invention will generally be present in the form of the alkali metal salt.
  • Preferred compounds are those in which R represents a methyl group, an ethyl group or an NH group.
  • a proportion of water may be present in the powders of the invention usually due to its presence as water of hydration in the salts used.
  • the amount of water present should not be so great as to cause any deleterious eifects in the composition.
  • the amount of water should, in any case, not exceed 6% by weight of the composition and it is preferred to use anhydrous compositions when lithium hypochlorite is present.
  • alkaline inorganic detergent by weight of the powder
  • organic soapless detergent by weight of the powder
  • the proportion of hypochlorite compound will vary with the individual compound used, generally 01-15% Will be used.
  • chlorinated trisodium phosphate 0.5 to 15 may be used, 1 to 5% being preferred.
  • lithium hypochlorite at a level of 45% available chlorine
  • 0.25% to by weight of the powder may be used, 1% to 5% being preferred.
  • the ratio of solid alkali metal hypochlorite compound to sulphonamide compound may be as high as 8:1 but a ratio of from 4:1 is preferred. Generally, not less than 0.5:1 will be used.
  • the ratio of sulphonarnide compound to organic soapless detergent should not be less than 0.05 :1 while the preferred range is from 0.2:1 to 1:1. Generally, not more than 5% by weight of the composition is required.
  • the detergent powders according to the invention may be made by any conventional method although any processing should avoid conditions under which a significant proportion of the ingredients might decompose. It is preferred that the inorganic hypochlorite compound should be the last ingredient to be added.
  • Example 1 A detergent powder was made up to the following formulation:
  • the powder possessed good storage properties. 1% aqueous solutions of the powder possessed good bactericidal properties.
  • Example 2 A detergent powder was made up to the following formulation:
  • inorganic detergent salt selected from the group consisting of the sodium and potassium silicates, phosphates, carbonates, and borates; from about 0.5% to about 15% of a synthetic organic nonsoap detergent selected from the group consisting of anionic and nonionic synthetic organic nonsoap detergents; from about 0.1% to about 15% of a solid alkali metal hypochlorite compound; and an amount up to about 5% of a compound selected from the orthoand para-substituted benzene sulfonarnides of the general formula
