Definitions

  • This invention relates to the use of a fabric softening clay as an additive in a fabric washing composition comprising an anionic surfactant, a nonionic surfactant and a proteolytic enzyme.
  • the clay may be added in the form of a granule comprising 10 to 30% by weight nonionic surfactant.
  • a mode of addition is advantageous for a granular detergent composition because it enables the clay to be conveniently post-dosed to the formulation.
  • the non-ionic provides for easy granulation of the clay.
  • the clay is selected from layered smectites and hectorites as these are the common naturally occurring fabric softening clays.
  • Clay mineral containing materials useful in the present invention include dioctahedral and trioctahedral three layer smectite clays, ideally of the calcium and/or sodium montmorillonite type.
  • PRASSA clay from Greece, GELWHITE from Texas USA, Willemse from South Africa and VOLCLAY BC from Wyoming.
  • the effectiveness of a clay containing material as a fabric softener will depend partly on the level of clay mineral in the material.
  • the clay is a bentonite such as a montmorillonite.
  • composition may further comprises Lipolytic enzyme, such as Lipolase.
  • Lipolytic enzyme such as Lipolase.
  • the clay also prevents some damage to wool which may be attributable to such other enzymes.
  • Anionic surfactants useful in the present invention include: Linear alkyl sulphonates.
  • suitable synthetic anionic detergent compounds are sodium and potassium alkyl sulphates, especially those obtained by sulphating higher (C8-C18) alcohols produced for example from tallow or coconut oil, sodium and potassium alkyl (C9-C20) benzene sulphonates, particularly sodium linear secondary alkyl (C10-C15) benzene sulphonates; sodium alkyl glyceryl ether sulphates, especially those ethers of the higher alcohols derived from tallow or coconut oil and synthetic alcohols derived from petroleum; sodium coconut oil fatty monoglyceride sulphates and sulphonates; sodium and potassium salts of sulphuric acid esters of higher (C8-C18) fatty alcohol-alkylene oxides, particularly ethylene oxide, reaction products; the reaction products of fatty acids such as coconut fatty acids esterified with isethionic acid and neutralised with sodium hydro
  • nonionic surfactants which may be used include in particular the reaction products of compounds having a hydrophobic group and a reactive hydrogen atom, for example aliphatic alcohols, acids, amide or alkyl phenols with alkylene oxides, especially ethylene oxide either alone or with propylene oxide.
  • Specific nonionic detergent compounds are alkyl (C6-C22) phenols-ethylene oxide condensates, generally up to 25 EO, i.e. up to 25 units of ethylene oxide on average per molecule, the condensation products of aliphatic (C8-C18) primary or secondary linear or branched alcohols with ethylene oxide, generally up to 40 EO, and products made by condensation of ethylene oxide with the reaction products of propylene oxide and ethylenediamine.
  • Other so-called nonionic detergent compounds include long chain tertiary amine oxides, long chain tertiary phosphine oxides and dialkyl sulphoxides.
  • detergent compounds for example mixed anionic or mixed anionic and nonionic compounds may be used in the detergent compositions, particularly in the latter case to provide controlled low sudsing properties. This is beneficial for compositions intended for use in suds-intolerant automatic washing machines.
  • Amounts of amphoteric or zwitterionic detergent compounds can also be used in the compositions of the invention but this is not normally desired due 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.
  • a detergency builder may also be present. This may be any material capable of reducing the level of free calcium ions in the wash liquor and will preferably provide the composition with other beneficial properties such as the generation of an alkaline pH, the suspension of soil removed from the fabric and the suspension of the fabric softening clay material.
  • the level of the detergency builder may be from 10% to 70% by weight, most preferably from 25% to 50% by weight.
  • Proteolytic enzymes that may be used in the present invention include the Savinases, such as Savinase 6.0T (ex Novo), Opticlean (Solvay) and Maxacal (Ibis) also Alcalases such as Alcalase 2.34 LVX and Esperase 8.0 (Novo), Optimase (Solvay) and Maxatase (Ibis).

  • Opticlean Solvay
  • Maxacal Ibis
  • Alcalases such as Alcalase 2.34 LVX and Esperase 8.0 (Novo)
  • Optimase Solvay
  • Maxatase Ibis
  • a detergent composition of the invention can contain any of the conventional additives in the amounts in which such additives are normally employed in fabric washing detergent compositions.
  • these additives include additional fabric softening agents such as a cationic fabric softening agent or a fatty amine.
  • 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 trichlorisyocyanuric acid, inorganic salts such as sodium sulphate, other fillers such as kaolin, and, usually present in very minor amounts, fluorescent agents, perfumes, other enzymes such as amylases, germicides and colorants.

  • lather depressants oxygen-releasing bleaching agents such as sodium perborate and sodium percarbonate, peracid bleach precursors, chlorine-releasing bleaching agents such as trichlorisyocyanuric acid, inorganic salts such as sodium sulphate, other fillers such as kaolin,
  • Fabric washing powders of the following compositions were prepared by conventional techniques.
  • the clay nonionic granule used for composition B was prepared by aggregation and post dosed to the base powder.
  • the base powder for composition B was the same as that for composition A except for the addition of the clay/nonionic granules.
  • Table 1 Composition A Composition B Anionic 18.5 16.65 Nonionic 4.6 4.14 Savinase 6.0T 0.65 0.85 Zeolite 35.9 32.31 Sodium carbonate 12.4 11.16 Polymer 4.4 3.96 Sodium bicarbonate 4.0 3.6 Water 14.5 13.05 Lipolase 100T 0.30 0.27 Minor Ingredients 4.75 4.275 Clay/nonionic - 10
  • compositions were used in a computer controlled Miele washing machine using a 40°C cotton programme. This programme was selected in order to show the damage effects of washing with a powder containing an enzyme more rapidly than would have been the case if the wool wash programme had been used. The order of the different compositions should not be affected by this procedure although the relative positioning may be changed by the amplification of damage resulting from increased agitation.
