Definitions

  • the present invention relates to an aqueous, built liquid detergent composition with an improved storage stability at low temperatures.
  • Aqueous, built liquid detergent compositions are well-known in the art. They are usually based upon an active-detergent system together with suitable builder salts, and, to provide for the required stability on storage they normally comprise a hydrotrope system. Such hydrotrope systems are manifold, the most well-known being toluene-, xylene-, or cumene-sulphonates, alkanephosphonates, and solvents such as ethylalcohol. Frequently, however, the choice of a suitable hydrotrope is restricted by the type of active detergent and builder salt, and although satisfactory results can be obtained e.g. when the product is stored at room temperature, less satisfactory results are achieved when the product is stored under changing temperature conditions, or at lower temperatures.
  • an aqueous built liquid detergent composition with improved low-temperature storage stability comprises a nonionic detergent-active system, a water-soluble builder salt, and a mono alkyl- or alkenylsuccinate hydrotrope, and furthermore a small amount of an alkylarylsulphonate as hereinabove defined.
  • the nonionic detergent-active system used in the present invention can be any suitable type of well-known nonionics, either alone or mixtures thereof.
  • Nonionics are alkylene oxide condensation products with hydrophobic organic compounds. Typical examples are ethylene- and/or propylene-oxide condensation products with alcohols, fatty acids, alkylphenols, fatty acid amides, and glycols. Numerous examples can be found in Schick, "Nonionic Surfactants", 1967.
  • the amount of nonionic detergent active ranges from 5-25% by weight, the preferred range being 6-20% by weight.
  • the water-soluble builder salts used in the present invention can be organic. and/or inorganic builder salts, such as sodium citrate, sodium carboxymethyloxysuccinate, sodium nitrilotriacetate, sodium carbonate, sodium or potassium salts of ortho-, pyro- or tripolyphosphoric acid, such as sodium and potassium tripolyphosphate, tripotassium orthophosphate, tet,rapotassiumpyrophosphate, and mixtures thereof.
  • the amount of the phosphate builder salts ranges from 5-25% by weight, the preferred range being 12-20% by weight.
  • the mono alkyl- or alkenyl-succinate hydrotrope to be used in the present invention contains from 7-12, particularly from 8-9 carbon atoms in the alkyl or alkenylgroup. These groups may be branched or straight-chain, the latter being preferred. They may be used in the acid or anhydride form, their corresponding salts being formed in situ in the composition by neutralisation with alkaline material present therein, or they may be added in their salt form. Suitable salts are the alkalimetal, ammonium or substituted ammonium salts.
  • the amount of the alkyl- or alkenyl succinate ranges from 3-15% by weight, the preferred range being from 4-10% by weight.
  • the composition of the invention may furthermore comprise other ingredients, commonly used in aqueous, built liquid detergent compositions, Thus, it may comprise alkaline material such as potassiumhydroxide or potassium carbonate (up to 10%), sequestering agents such as ethylene-diaminetetraacetic acid, ethanehydroxydi- phosphonic acid, ethylenediaminetetraphosphonic acid, triethanolamine etc. (up to 2%), foam depressors such as soaps, silicones, paraffins etc. (up to 5%), fluorescers in minor amounts, enzymes, perfumes, colouring agents, germicides, anti-soil redeposition agents and so on.
  • alkaline material such as potassiumhydroxide or potassium carbonate (up to 10%)
  • sequestering agents such as ethylene-diaminetetraacetic acid, ethanehydroxydi-
  • the alkylbenzenesulphonate which is used according to the present invention is an alkalimetal ammonium or substituted ammonium salt of alkylbenzenesulphonic acid, in which the alkylgroup is branched or, preferably, straight-chain and which comprises from 10-15 carbon atoms. Suitable examples are sodium or potassium straight-chain C 12 -alk y lbenzenesulphonate.
  • these sulphonates is used, from 0.5-3% by weight, the preferred range being from 0.75-1.5% by weight.
  • compositions of the invention can be prepared in any suitable manner; it is however advantageous to add the hydrotrope to the composition prior to the phosphate builder salts and neutralize the hydrotrope in situ.
  • the products of the invention are particularly suitable for industrial laundering, especially to prepare stock solutions therefrom to be used in industrial laundering processes where these solutions are automatically dosed into the washing system. They are of particular benefit for the laundering of polyester/cottong laundry.
  • compositions were prepared: These compositions were stored under cycling conditions, i.e. at temperatures of -12°C and + 20°C changing the temperature every 24 hours, which was repeated 6 times, as well as in a refrigerator (temp.+3°C). Their stability was visually assessed as to phase separation. The following results were obtained: The figures in the above table denote the amount of days after which instability, i.e. phase separation was observed. It can be seen that the addition of the alkylbenzenesulphonate in each case greatly enhances the storage stability under both storage conditions.
