Definitions

  • the invention is directed to a process for the production of a powdered washing, bleaching and cleansing agent, which contains as a bleaching constituent active oxygen compounds of boric acid salts in a largely inseparable form.
  • the solidification of the individual particles can take place in two ways.
  • cold-spraying processes such materials are added to the washing agent composition which crystallize in the airstream at normal temperature with the addition of water. Since these processes largely confine the user in the selection of the washing agent component and a large powdered spray is obtained with a high apparent density preferably there is used a hot spray or spray drying process. According to such process hot air is introduced into the spraying tower, which is allowed to remove excess amounts of water from the atomized slurry and thus to obtain a practically dustfree advantageous spray with a low apparent density.
  • a special problem occurs in the manufacture of the washing agent in the introduction of the necessary bleaching constituents of active oxygen-containing compounds, especially sodium perborate into the washing agent composition. Since the active oxygen-containing compounds by the action of elevated temperatures and the presence of specific other chemicals are inclined to decompose, the sodium perborate or other active oxygen-containing compounds of the acids of boron are added in general subsequent to the spraying.
  • washing agent constituent and sodium perborate will become mixed with each other as uniformly as possible, still there can occur by the presence of unfavorable conditions inhomogeneities in the filled washing agent parcels, which are detrimental to the desired bleaching effect in the use of the washing agent.
  • a cementing of the two ingredients accomplished in this manner can certainly lead to a better homogeneity of the resulting wash powder.
  • it has the disadvantage that a uniform mixing cannot be attained with certainty and the gluing together of the particles often is not sufficiently hardy against mechanical stress.
  • sodium metaborate is added to the slurry. Surprisingly there is only a slight decomposition of the active oxygencontaining compound in spite of the relatively high temperature of the slurry stream and the temperature at which the mixture is sprayed in the process of the invention.
  • stabilizers there can be used for example sodium silicate, magnesium silicate, magnesium chloride, magnesium sulfate, sodium pyrophosphate,
  • sodium stannate sodium salt of ethylenediamine-tetra acetic acid.
  • potassium metaborate a mixture of sodium tetraborate and sodium hydroxide which forms sodium metaborate, a mixture of potassium tetraborate and potassium hydroxide which forms potassium metaborate, a mixture of boric acid and sodium hydroxide which forms sodium metaborate as well as boric acid and potassium hydroxide which forms potassium metaborate.
  • a washing, bleaching and cleansing agent that contains as the bleaching agent an addition compound of sodium tetraborate and hydrogen peroxide, the so-called perborax (Na B 3 H 0
  • perborax Na B 3 H 0
  • potassium tetraborate a mixture of boric acid and sodium hydroxide which forms sodium tetraborate as well as a mixture of boric acid and potassium hydroxide which forms potassium tetraborate.
  • Marlon A 375 (a 75 percent solution in water of sodium alkylbenzenesulfonate containing 12 carbon atoms in the alkyl group) 600 parts of neutral sodium pyrophosphate 60 parts magnesium silicate 40 parts carboxymethylcellulose 232 parts sodium metaborate (NaBO '4H,0)
  • EXAMPLE 2 To produce a slurry there were introduced to 2,628 parts of water at 80 C. the following constituents parts of Marlon A 375 300 parts of neutral sodium pyrophosphate 15 parts of magnesium silicate 36 parts of magnesium chloride hexahydrate 20 parts of carboxymethyl cellulose 128 parts of anhydrous sodium sulfate The slurry thus produced was introduced into a spray tower in the course of about an hour. Immediately before introduction of the slurry into the spray nozzle there was uniformly added the following mixture.
  • the wash powder obtained had a content of 1.38 percent active oxygen and 1.25 percent boron, which corresponds to 8.73 percent perborax (Na B O-,-3H O
  • Conventional spray drying temperatures can be used.
  • the entrance temperature is usually between 100 and 600 C. and the exit temperature usually between 50 and 300 C.
  • the slurry which is spray dried generally contains l5 to 95 percent solids, the balance being water.
  • hydrogen peroxide in addition to hydrogen peroxide as the active oxygen carrier there can be used sodium peroxide or potassium peroxide.
  • detergents examples include sodium, stearate (soap), sodium palmitate, potassium stearate, sodium oleate, potassium oleate, higher alkylaryl sulfonates containing 8-22 carbon atoms in the alkyl group, e.g. higher alkyl benzene sulfonates and higher alkyl phenol sulfonates.
  • sodium decyl benzene sulfonate sodium dodecyl benzene sulfonate, potassium dodecyl benzene sulfonate, sodium keryl sulfonate, sodium nonyl benzene sulfonate, sodium decyl phenol sulfonate, potassium pentadecyl benzene sulfonate, ammonium dodecyl benzene sulfonate, triethanolamine decyl benzene sulfonate, sodium octadecyl benzene sulfonate.
  • anionic detergents include nonnal and secondary higher alkyl sulfates having 8-22 carbon atoms in the alkyl residue such as sodium lauryl sulfate, potassium lauryl sulfate, sodium octadecyl sulfate, sodium coconut fatty alcohol sulfate, sodium octyl sulfate, as well as the corresponding long-chain aliphatic sulfonates, e.g.
  • sodium octane sulfonate sodium dodecane sulfonate, sodium tetradecane sulfonate, sodium octadecane sulfonate, potassium dodecane sulfonate, higher alkyl ether sulfates, higher alkyl glyceryl ether sulfates, higher alkylphenol polyethylene oxide sulfates, polyethylene oxide condensates with higher alkyl phenols such as isooctyl and nonyl phenol condensed with 8-22 moles of ethylene oxide, e.g. with 10 moles of ethylene oxide.
  • Phosphate builders can be included such as trisodium phosphate, tetrasodium pyrophosphate, sodium hexameta phosphate, tetra potassium pyrophosphate, potassium tripolyphosphate, sodium tripolyphosphate.
  • alkali and alkaline earth metal silicates also can be included such as sodium silicate, magnesium silicate and potassium silicate.
  • Other conventional additives can also be present such as sodium sulfate, potassium sulfate, sodium chloride, magnesium chloride, sodium carbonate, potassium carbonate, sodium acetate, ammonium sulfate as well as carboxymethyl cellulose and its sodium and potassium salts and polyvinyl alcohol.
  • the slurry consists essentially of the detergent, active oxygen compound, a phosphate builder and a sulfate additive, the detergent is an anionic detergent, the slurry has a temperature of C. the entrance temperature of the spray drier is to 600 C. and
  • the exit temperature is 50 to 300 C.
  • the active oxygen compound contains sodium perborate and the slurry contains either the borate component or the alkali component of sodium metaborate and the other of the borate or alkali component is added together with the hydrogen peroxide to the slurry shortly before the spraying.
  • a process according to claim 1 wherein the active oxygen compound contains perborax and sodium tetraborate as well as hydrogen peroxide are introduced into the slurry shortly before spraying.
