Definitions

  • the Japanese patent application 61 069897 discloses a process in which a spray-dried detergent powder containing a high level of anionic surfactant and a low level of builder (zeolite) is subjected successively to a pulverizing and a granulating treatment in a high-speed mixer/granulator.
  • the granulation is carried out in the presence of an "agent for improving surface properties" and optionally a binder.
  • the starting material for the process according to the invention comprises (a) from 10 to 70% by weight of non-soap detergent active material, and (b) at least 15% by weight of water-soluble crystalline inorganic salts, including sodium tripolyphosphate and/or sodium carbonate, the weight ratio of
  • the detergent active material may be selected from non-soap anionic, ampholytic, zwitterionic or nonionic detergent active materials or mixtures thereof. Particularly preferred are all anionic or mixtures with nonionic detergent active materials such as a mixture of an alkali metal salt of an alkyl benzene sulphonate together with an alkoxylated alcohol.
  • the preferred detergent compounds which can be used are synthetic anionic and nonionic compounds.
  • the former are usually water-soluble alkali metal salts of organic sulphates and sulphonates having alkyl radicals containing from about 8 to about 22 carbon atoms, the term alkyl being used to include the alkyl portion of higher acyl radicals.
  • nonionic detergent compounds include long-chain tertiary amine oxides, long-chain tertiary phosphine oxides and dialkyl sulphoxides.
  • Amounts of amphoteric or zwitterionic detergent compounds can also be used in the compositions of the invention but this in not normally desired owing to their relatively high cost. If any amphoteric or zwitterionic detergent compounds are used, it is generally in small amounts in compositions based on the much more commonly used synthetic anionic and/or nonionic detergent compounds.
  • the granulation step is similarly carried out by running the stirrer and the cutter at a relatively high speed, but here the presence of a liquid binder is necessary.
  • the preferred binder is water.
  • the amount of binder added should preferably not exceed about 6 % by weight, because higher levels may adversely affect the flow properties of the final product.
  • the liquid binder may be added before or during granulation, preferably by spraying it in while the apparatus is running.
  • the starting material may also already contain sufficient moisture, such that addition of further liquid binder is not necessary. In this case, pulverization and granulation may be carried out as a single operation.
  • a clay-containing material as a fabric softener will depend amongst other things on the level of smectite clay. Impurities such as calcite, feldspar and silica will often be present. Relatively impure clays can be used, provided that such impurities are tolerable in the composition.
  • the level of the fabric-softening clay material in the composition should be sufficient to provide a softening benefit. Amounts from 1.5% to 35% by weight, preferably from 4% to 20% by weight, calculated on the basis of the clay mineral per se were found to be effective.
  • the compositions according to the invention optionally may contain other ingredients usually found in detergent compositions, in the amounts in which such additives are normally employed in fabric-washing detergent compositions.
  • additives include the lather boosters such as alkanolamides, particularly the monoethanolamides derived from palm kernel fatty acids and coconut fatty acids, lather depressants, oxygen releasing bleaching agents such as sodium perborate and sodium percarbonate, peracid bleach precursors, chlorine releasing bleaching agents such as trichloroisocyanuric acid, fillers such as sodium sulphate, and, usually present in very minor amounts, fluorescent agents, perfumes, enzymes such as proteases, lipases and amylases, germicides and colorants.
  • the process of the present invention enables the preparation of detergent compositions having a high bulk density of at least 550 g/l. It is a surprising advantage of the process of the invention that the bulk density of the obtained powders is higher than when the clay is admixed to the crutcher slurry prior to spray-drying of the starting material.
  • Example 2 contained a Ca-clay (Prassa ex Colin Stewart Minerals, U.K.) which was added to the crutcher slurry and spray-dried. Sodium carbonate was in this case omitted from the slurry to maintain it at a sufficiently low viscosity to aid in spray-drying.
  • Example 3 was a spray-dried powder without clay but including carbonate.
  • Example 2 When the clay was added separately to the wash using the composition of Example 1, a softness value of 97.5 was found. Comparison of this value with the softness value of 99.5 found for Example 3 indicates that essentially the full softening performance is delivered by the process of the invention. However, when the clay was added to the crutcher slurry prior to spray-drying as in Example 2, a much lower softness value of 75.3 was found.
