Definitions

  • non-aqueous liquid detergent compositions are characterized by the following weakness: they may tend to suffer from gelling and the ingredients tend to stick together. As a consequence thereof, the product may disperse only slowly in water and this may have a negative influence on the cleaning performance of the product, e.g. the product will not uniformly and timely dissolve in the washing liquor.
  • dispersion problems of non-aqueous liquid detergent compositions may occur upon dilution with water.
  • Low dispersion may for example lead to high concentrations of product on the cloth that may have negative effects on the cloth's quality.
  • WO 94/12611 discloses non-aqueous liquids comprising dry particulate solubilised biopolymer material to improve the dispersion of the liquid.
  • Preferred biopolymers are polysaccharides and polypeptides.
  • EP-A-28,849 discloses non-aqueous liquids comprising a stabilising polymer that is an at least partially hydrolysed copolymer of maleic anhydride with ethylene or vinylmethylether.
  • the use of the polymeric hydrotrope in non-aqueous liquids according to the invention may have certain advantages compared with use of conventional hydrotropes, including low foaming properties, good surfactant solubilising characteristics, chemical stability, ease of handling, cost effective, substantially free of nitrosamines commonly associated with compositions using nitrogen-based hydrotropes or solubilisers, such as amine oxides.
  • polymer hydrotrope has been found to lead to reduced gelling, improved dispersion, dissolution and/or dispensing of compositions comprising high surfactant levels.
  • a surfactant-composition with a polymeric hydrotrope leads to reduced gelling characteristics upon dilution, improved dispersion, dissolution and/or dispensing when mixing the composition with water.
  • the polymeric hydrotrope may be a copolymer, in block and/or random form.
  • the polymer comprises hydrophillic and hydrophobic monomers.
  • the hydrophobic monomer is styrene.
  • a particularly preferred polymer comprises 50.81 wt% acrylic acid, 48.93 wt% styrene, 0.26 wt% DDM, with a molecular weight of about 1,000 and substantially no cross-linking. This polymer is found to be very versatile and to have a wide range of uses and applications.
  • Another preferred polymer comprises 54 wt% methacrylic acid and 46% styrene, with a molecular weight of about 100,000 and substantially no cross-linking.
  • Such a polymer is found to be hypochlorite-stable and to be an effective thickener in hypochlorite bleach.
  • Suitable polymers can be readily made in conventional manner, eg. by emulsion or solution polymerisation, and are preferably in the form of low viscosity non-aqueous solutions or powders.
  • Composition of the present invention may comprise surfactant material, non-surfactant material, solvent material and other liquid material such as deflocculant material.
  • alkylphenols preferably from 12 to 20 carbon atoms
  • dialkylphenols in which each alkyl group contains from 6 to 2 carbon atoms
  • primary, secondary or tertiary aliphatic alcohols or alkyl-capped derivatives thereof
  • monocarboxylic acids having from 10 to about 24 carbon atoms in the alkyl group and polyoxypropylenes.
  • Typical examples of suitable peroxy bleach are alkali-metal perborates, both tetrahydrates and monohydrates, alkali metal percarbonates, persulphates, per-silicates, perphosphates and peracids.
  • Perborate and percarbonate are preferred, in particular in the sodium form.
  • the inorganic builders comprise the various phosphate-, carbonate-, silicate-, borate- and aluminosilicates-type materials, particularly the alkali-metal salt forms. Mixtures of these may also be used.
  • non-aqueous liquid detergent compositions can be improved and/or setting problems can be minimised, if dispersants are used.
  • ingredients comprise those remaining ingredients which may be used in detergent compositions, such as fabric conditioning agents, abrasive material, enzymes, enzyme stabilising agents (if necessary), fluorescers, perfumes (including deoperfumes), micro-biocides, soil-suspending agents (anti-redeposition agent), corrosion inhibitors, and lather depressants.
  • compositions (B and 2) were prepared with 10g Vista 1012-62 and Dobanol 25-3 (weight ratio 55/45) mixed with 2g STP.
  • the nonionic of composition 2 additionally contained 2% of the Narlex polymer.
  • Composition 2 showed less gelling in the gelling test than composition B.
  • compositions were prepared containing 10g Dobanol 25-3 and 2g soda.
  • Composition 13 additionally contained 4% of the Narlex polymer and had far lower gelling behaviour than composition F (that showed lump formation).
  • compositions were prepared with 10g Dobanol 25-3 mixed with 2g Magnesium Sulphate.
  • the nonionic of composition 19 additionally contained 2% of the Narlex polymer.
  • Composition 19 showed less gelling in the gelling test than composition M.
  • Composition 23 was prepared without polymer (T) and with 1 % Narlex polymer (32). Composition T was dispersed after 29 minutes, whereas composition 32 was dispersed after 22 minutes.

Abstract

Cette invention concerne une composition détergente liquide comprenant un hydrotrope polymère. Le polymère doit posséder au moins l'une des qualités suivantes, à savoir une dispersion accrue, une dissolution accrue ou une capacité de répartition accrue, ceci pour résoudre, en partie du moins, les problèmes de gélification, notamment dans de faibles niveaux d'eau. Il est également préférable que la composition comprenne un matériau électrolytique. Cette invention concerne également une composition contenant un agent tensioactif et un hydrotrope polymère, ainsi qu'un procédé de préparation d'une composition détergente non-aqueuse. Cette invention concerne enfin un procédé d'application d'une composition et un procédé pour mélanger une composition avec de l'eau,

Claims (4)

  1. Composition détergente liquide non aqueuse comprenant une phase liquide non aqueuse, qui comprend de 10 % à 90 % en poids de la composition de tensioactif non ionique liquide, dans laquelle la composition comprend un hydrotrope polymère comprenant des monomères hydrophiles et hydrophobes, le monomère hydrophile étant l'acide acrylique ou l'acide méthacrylique et le monomère hydrophobe étant le styrène, dans laquelle la composition comprend en plus un électrolyte.
  2. Composition selon la revendication 1, dans laquelle le rapport molaire entre les monomères hydrophiles et les monomères hydrophobes dans le polymère est de 5:1 à 1:5.
  3. Composition selon l'une quelconque des revendications précédentes comprenant en plus des particules solides dispersées.
  4. Procédé de préparation d'une composition détergente non aqueuse selon l'une quelconque des revendications précédentes, dans lequel l'hydrotrope polymère est ajouté à la composition sous une forme comprenant 25 % ou moins en poids d'eau.
