Definitions
- the present invention relates to compositions which comprise polymer material and to a method of preparing such compositions.
- Detergent compositions may be aqueous or non-aqueous, both either in solid or in liquid form.
- Non-aqueous liquid detergent compositions are known in the art and have been described in quite a number of patent publications, e.g. in US-A-4,316,812, US-A-4 ,874 , 537 and EP-A-0,484 , 095.
- the free water content of non-aqueous liquid detergent compositions is less than 5% by weight, preferably less than 3% by weight, more preferably less than 2% by weight, most preferably substantially nil.
- Non- aqueous liquid detergent compositions provide a way of concentrating liquid detergents without giving in on washing performance.
- Non-aqueous liquid detergent compositions normally comprise a non-aqueous liquid phase having incorporated therein as dispersion, solution or combination thereof, the usual detergent components and adjuncts depending on the purpose of use, primarily surfactants and builders.
- the non-aqueous liquid phase often comprises a nonionic surfactant as major component, which apart from acting as carrier liquid for the other detergent components, usually and preferably also has detergent-active properties, thereby acting wholly or in part as the surfactant ingredient.
- 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.
- liquid phases comprising a nonionic surfactant, such as mixtures of C13-C15 alcohols with an average of 3 ethoxy groups and C13-C15 alcohols with an average of 7 ethoxy groups and liquid phases as described in GB-A-1 , 462 , 134 , WO-A-91/12313 , WO-A-91/14765 and EP-A-0 , 510 , 762 and more in particular for liquids comprising a dispersed solid particulate phase.
- a nonionic surfactant such as mixtures of C13-C15 alcohols with an average of 3 ethoxy groups and C13-C15 alcohols with an average of 7 ethoxy groups and liquid phases as described in GB-A-1 , 462 , 134 , WO-A-91/12313 , WO-A-91/14765 and EP-A-0 , 510 , 762 and more in particular for liquids comprising a dispersed solid particulate phase.
- these solvent materials may be beneficial in at least partially overcoming the gelling problem of non-aqueous liquid detergent compositions.
- these materials are only effective to overcome gelling caused at relatively high water levels, whereas they are less effective or even ineffective in overcoming relatively low water level gelling problems, e.g. at water levels in which 5 to 50% by weight of water is added to the product.
- Gelling problem of non-aqueous liquids are not only noticeable for non-aqueous liquid containing a non-aqueous phase, but also, and in particular, when solid dispersed particles are present.
- 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.
- a further problem related to the use of non-aqueous liquid compositions is dissolution. Slow dissolution of the concentrated composition may result in liberation of the components to the wash liquor only at a late stage during the washing process, at which point they may be less effective.
- Another problem that is in particular important in the industrial area is the dispensing problem of non-aqueous liquids, i.e. the blocking of pipes and valves of the dosing system for non-aqueous liquid detergent compositions.
- This problem has e.g. been described in EP-A- 480,490 (Unilever) .
- compositions comprising from 10 to 90% by weight of surfactant material.
- the compositions are preferably non-aqueous (either solid or preferably liquid) ,
- compositions are preferably non-aqueous (either solid or preferably liquid) .
- compositions are preferably non-aqueous (either solid or preferably liquid) .
- Non-aqueous liquids comprising polymeric material have for example been described in EP-A-510,762 (Unilever) that discloses non-aqueous liquids comprising a polymer material comprising at least one group capable of association with the solid phase and at least one group capable of extending from the solid phase.
- the polymer is amongst other incorporated to lower the viscosity and the clear layer separation.
- WO 94/01524 discloses non-aqueous liquids comprising a polymeric material with a group that exhibits self association to reduce viscosity and the clear layer formation of the liquids.
- WO 94/12611 discloses non-aqueous liquids comprising dry particulate solubilised biopoly er material to improve the dispersion of the liquid.
- Preferred biopoly ers are polysaccharides and polypeptides.
- EP-A-413,616 discloses non-aqueous liquid detergent compositions comprising nonionic surfactants, solid particles and a polymer derived from ⁇ ,j3-mono- ethylenically unsaturated carboxy-containing monomers.
- EP-A-359,491 (Unilever) and EP-A-359,492 (Unilever) disclose non-aqueous liquids comprising respectively low and high molecular weight vinyl pyrrolidone polymers.
- 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.
- GB-A-2 , 228, 944 discloses non-aqueous liquids comprising polymeric materials that may comprise acryl amide monomers.
- the present invention provides a non-aqueous liquid detergent composition comprising a non-aqueous liquid phase, wherein the composition comprises a polymeric hydrotrope comprising hydrophillic and hydrophobic monomers.
- the non-aqueous liquids according to the invention comprise an electrolyte material.
- liquid composition of the present invention further comprise at least one ingredient selected from abrasives, bleaches, bleach catalysts, bleach precursors, corrosion inhibitors, dispersants, enzymes, fabric softening agents, icrobiocides and mixtures thereof.
- these ingredients are included at levels of from 0.01 to 90% by weight of the composition.
- the non-aqueous liquids according to the invention comprise solid dispersed particles which are more preferably selected from bleaches, builders, abrasives, dispersants, enzymes, solid surfactants, fluorescers, enzymes, bleach precursors, bleach catalysts, colorants, pigments, opacifying agents and mixtures thereof.
- the present invention further provides a composition comprising from 10 to 90% by weight of surfactant material and further comprising a polymeric hydrotrope.
- the invention further provides a method of preparing a non- aqueous liquid detergent composition comprising a non- aqueous phase and a polymeric hydrotrope, wherein the polymeric hydrotrope is added to the non-aqueous phase in a form comprising 25% or less by weight of water.
- the invention further provides a method of applying a composition by mixing the composition with a polymeric hydrotrope, whereafter the composition with the polymer is applied to a washing machine.
- the composition comprises surfactant material and more preferably nonionic surfactant material.
- the composition is non- aqueous (either solid or preferably liquid) .
- the invention further provides a method of mixing a composition with water, wherein the composition is prepared by mixing a surfactant with a polymeric hydrotrope, whereafter the composition is mixed with water.
- the composition comprises surfactant material and more preferably nonionic surfactant material.
