Definitions

  • the present invention relates to liquid detergent compositions and in particular to aqueous built liquid detergent compositions comprising a detergent active-based suspending system capable of suspending undissolved material.
  • Aqueous built liquid detergent compositions are well known and a vast amount of formulations have been described in the prior art.
  • Such compositions comprise one or more detergent-active compounds and one or more builder salts in an aqueous medium which is capable of suspending undissolved builder and/or adjuvant materials.
  • compositions of the above type which have reduced sensitivity to electrolyte material and which tolerate larger quantities of such material without giving rise to unacceptable viscosities.
  • FR 2 014 084 (Hoechst) describes unstructured detergent compositions which comprise fatty alcohol polyalkylene oxide carboxylate salts.
  • the present invention provides an aqueous built liquid detergent composition capable of suspending particulate material, which comprises from 1% to 15% by weight of synthetic anion detergent-active material and from 5% to 30% by weight of electrolyte salts, characterized in that it comprises from 0.5-10% by weight of a fatty alcohol polyalkylene oxide carboxylate salt or a mixture of such salts according to the formula:
  • R is an aliphatic hydrocarbon group having 8-20 carbon atoms or an aliphatic-aromatic hydrocarbon group having 4-20 carbon atoms in the aliphatic part; n is a number in the range of from 2 to 3 inclusive; x is a number in the range of from 1 to 16 inclusive; y is a number in the range of from 0 to 2 inclusive; and M is a cation.
  • R will normally comprise a mixture of aliphatic hydrocarbon groups of different lengths which may be straight or branched, saturated or unsaturated.
  • R is a straight saturated aliphatic hydrocarbon group having from 1-14 carbon atoms.
  • the number of ethylene and/or propylene oxide units (x) ma range from 1-16, in particular from 1-12.
  • the alkylene oxide portion comprises from 2-5 ethylene oxide units.
  • M is a cation and is selected from the group of hydrogen, sodium, potassium, ammonium, mono-, di- and triethanol ammonium, the alkali metal cations being preferred.
  • the fatty alcohol polyalkylene oxide carboxylate salt or a mixture of such salts is included in an amount of from 0.5-10%, partly replacing the synthetic anionic detergent-active material.
  • the preferred amount depends on the rheology of the composition without the carboxylate salt compound, and the rheology which is aimed at. In general the best results are obtained when the fatty alcohol polyalkylene oxide carboxylate salt is included in an amount of from 2-5% by weight, replacing about an equivalent amount of synthetic anionic detergent active material.
  • the invention relates to aqueous liquid built compositions on the basis of synthetic anionic detergent-active material and electrolyte salts.
  • Suitable synthetic anionic detergent-active materials comprise the well-known anionic detergents of the alkylaryl sulphonate type, the alkyl- and alkylether sulphate type, the alkane- and alkene sulphonate type, etc. Numerous other examples can be found in Schwartz, Perry “Detergents and Surface-Active Agents", Vol. 11, 1958.
  • alkylaryl sulphonates are used, in which the alkyl chain contains 10-18 carbon atoms, such as n-dodecyl benzene sulphonate, tetrapropylene benzene sulphonate, n-pentadecyl benzene sulphonate, and linear C, 2 --Cis alkylbenzene sulphonate in which the aliphatic group is obtained from cracked wax polymers, all in the form of their sodium or potassium salts.
  • n-dodecyl benzene sulphonate such as n-dodecyl benzene sulphonate, tetrapropylene benzene sulphonate, n-pentadecyl benzene sulphonate, and linear C, 2 --Cis alkylbenzene sulphonate in which the aliphatic group is obtained from cracked wax polymers, all in the form of their sodium or potassium
  • the total amount of synthetic anionic detergent active materials must lie within the range of 1-15% by weight, but preferably is 6-12% by weight of the total composition.
  • Nonionic detergents usually consist of a hydrophobic moiety which has been reacted with an alkylene oxide.
  • Suitable examples are primary or secondary, straight or branched chain Ca-Ge alcohols condensed with 1-30 moles of alkylene oxide; mono- or dialkyl phenols with an alkyl group of 9-18 carbon atoms condensed with 1-30 moles of alkylene oxide; Go-Ge fatty acid mono- or dialkylol amides condensed with 1-30 moles of alkylene oxide; block copolymers of different or identical alkylene oxides and so on.
  • the alkylene oxide is ethylene oxide, but propylene oxide or a mixture of ethylene oxide and propylene oxide can also be used. Further suitable examples can be found in the text book of M. Schick "Nonionic Surfactants".
  • the amount of nonionic detergent-active material which can be included in the composition ranges up to 5%, but such amounts should be less than the amount of synthetic anionic detergent active material.
  • the electrolytes which are used in the present invention are those which cause partial salting out of the detergent active material.
  • Typical examples are builder salts, such as the alkali metal ortho- and pyrophosphates, the alkali metal ammonium tripolyphosphates, such as sodium tripolyphosphate, the alkali metal citrates, alkyli metal salts of nitrilo triacetate and alkali metal salts of carboxy methyloxy succinate.
  • builder salts such as the alkali metal ortho- and pyrophosphates, the alkali metal ammonium tripolyphosphates, such as sodium tripolyphosphate, the alkali metal citrates, alkyli metal salts of nitrilo triacetate and alkali metal salts of carboxy methyloxy succinate.
  • Suitable examples of electrolytes are also buffering agents, such as the alkanol amines, in particular triethanol amine, alkali metal carbonates, alkali metal borates, alkali metal silicates, and so on.
  • compositions of the invention may further contain all ingredients usually encountered in such products, such as alkali metal sulphites, for improving detergency; enzymes, either alone or in combination with enzyme stabilizers, such as polyalcohols or alkanol amines with borax; fluorescers, further builders, such as zeolites; abrasives, such as calcite; soil-suspending agents; anti-redeposition agents; hydrotropes, corrosion inhibitors; foam boosters or depressors; opacifying agents; perfumes; colouring agents; bleaching agents, optionally in combination with bleach precursors; fluorescers.
  • enzymes either alone or in combination with enzyme stabilizers, such as polyalcohols or alkanol amines with borax
  • fluorescers further builders, such as zeolites
  • abrasives such as calcite
  • soil-suspending agents such as calcite
  • soil-suspending agents such as calcite
  • anti-redeposition agents such as
  • the products of the present invention can be prepared using conventional techniques. In this respect it has been found that it is advantageous to shear the product at the end of the production process to its maximum stable viscosity, e.g. by post-stirring or passing the product through a desintegrator or similar high-shear exerting equipment. Further shear exerted on the product thus treated during pumping and bottling does not affect the viscosity of the product.
  • compositions were prepared according to the formulations listed in Table 1, having good physical stability and clearly showing the increased tolerance to high electrolyte levels.
  • Akypo is the trade-name for a series of fatty alcohol polyglycolether carboxylates sold by Chem-Y, The Netherlands.
