Definitions

  • the present invention relates to a liquid, concentrated, stable detergent composition which can be diluted with water and such that the viscosity of the diluted composition is sufficiently high to satisfy consumers, while the viscosity of the concentrated composition is sufficiently low to allow it to be poured into containers.
  • the object of the invention is to manufacture a detergent composition which can preferably contain up to approximately 90% of surface-active materials and which can be diluted by several times its volume of water to obtain a final composition whose viscosity is satisfactory for the user.
  • a diluted composition having a high viscosity is perceived by consumers as being more effective than a composition with the same concentration of active materials, but of low viscosity.
  • the viscosity of the starting concentrated composition was too high to allow its industrial use.
  • Another object of the invention is to manufacture a clear detergent composition which, by dilution with water by the user, gives a clear, viscous, stable composition.
  • the problem to be solved is particular, because the dilution is carried out by the user and therefore under conditions which are not controllable.
  • the dilution is made with a variable amount of water.
  • This water is in particular tap water, and depending on the region, it can be more or less hard and contain different ions.
  • the water temperature is variable and can be between 0 and 20 ° C.
  • the bottle in which the dilution is made is arbitrary and can be a glass or plastic bottle, of various shapes.
  • compositions according to the invention are preferably used as a multi-purpose liquid, in particular for washing dishes.
  • alkanolamine salt of alkylbenzene sulfonic and alkyltoluene sulfonic acids is formed by the final addition of alkanolamine to the mixture of surfactants and the fatty acid alkanolamide, in the presence of cellulose derivatives. These salts are therefore formed in situ when the various compounds are mixed.
  • compositions are not intended to be diluted and therefore there is no concern for the viscosity of the diluted composition relative to the viscosity of the concentrated composition.
  • French Patent No. 1,501,661 describes a process for preparing a concentrated detergent composition liquid, which comprises adding a compound of agent surface B of the type mentioned above, a diethanolamine, to pour the alkylbenzenesulfonic acid or alkyltoluene -sulfonic acid to effect its neutralization, then to add a fatty acid amide of ethanolamine.
  • alkylbenzene- or alkyltoluene-sulfonic acid salts is carried out by in situ neutralization, that is to say during the mixing of the various constituents of the detergent composition.
  • compositions comprising a amidobetaine, an organic or inorganic salt, water and an anionic surfactant present in amounts between 0.25 and 15% by weight.
  • the purpose described in this document is to obtain a thickened aqueous solution by adding 5 to 25% by weight of amidobetaine.
  • the compositions obtained can be clear or opaque and can be gels or pastes. These compositions are not very concentrated and contain 50 to 70% of water.
  • European Patent application No. 88612 discloses detergent dilutable liquid compositions containing more than 90% by weight of detergent materials containing more than 50 wt% coconut ethanolamide derivative and polyether, namely more than 50% of agents non-ionic surface.
  • these compositions have a moderate detergent action, since the detergent activity of nonionic surfactants is weaker than that of anionic surfactants.
  • these compositions are ternary mixtures which do not contain salt for thickening, since the latter tends to precipitate.
  • British Patent No. 1164854 discloses detergent compositions containing ammonium or amine salts of alkylbenzenesulfonates, ethoxylated alcohols and metal salts of di- or trivalent, eg magnesium sulfate. But the viscosity of the compositions at 30% of active ingredients is not adjustable depending on the salt level and the compositions diluted to 15% of active ingredients are cloudy.
  • the present invention further aims to provide liquid, concentrated, clear, dilutable compositions containing more than 50% by weight of anionic surfactants relative to the total amount of active materials.
  • French Patent No. 2,156,825 discloses aqueous concentrates of sulfates of alkoxylated alcohols with a viscosity lowered by compounds such as lactic acid, glyceric acid, tartaric acid or citric acid, which makes it possible to dilute without gel formation.
  • French Patent No. 2,304,665 relates to compositions containing an olefin sulfonate which is added an acid salt to lower the viscosity of the concentrated compositions. This patent further relates to dilute compositions of these olefin sulfonate and acid salt mixtures. An alkanolamide may optionally be added to the diluted compositions in order to increase the viscosity of this composition.
  • this patent describes a concentrated composition which contains an anionic surfactant and a salt, or a diluted composition to which a nonionic surfactant is added.
  • French Patent No. 2,343,804 discloses a composition containing a nonionic polyethoxylated surfactant, and an acid whose function is to increase the detergency of the composition.
  • U.S. Patent No. 4,092,273 discloses a detergent composition which contains an anti-gelling agent at low temperature. This agent is a diacid salt.
  • French Patent No. 2106927 describes a descaling composition containing a detergent, an acid and a thickener based on cellulose ether.
  • the Applicant has been able to produce detergent compositions concentrated, limpid, dilutable with water, the dilution of which gave diluted compositions having a viscosity which is not appreciably lowered but on the contrary could even be adjusted with respect to the viscosity of the concentrated composition as desired by adding acids or their soluble salts in the concentrated composition, composition containing anionic surfactants in an amount greater than the amount of nonionic surfactants.

  • the anionic surfactant (a) is an alkylbenzenesulfonic acid whose alkyl chain contains from 10 to 12 carbon atoms, neutralized by an amine containing from 1 to 3 alkylol groups, more preferably monoethanolamine which confers a slightly lower viscosity to the concentrated composition, which makes it possible to reduce the level of non-aqueous solvent, and therefore to introduce a higher level of active materials in the composition.
  • an essential characteristic of the invention is that the anionic surfactant or the mixture of anionic surfactants, in solutions containing more than 40% by weight of active materials must be chosen so as to contain sufficiently few ions capable of forming precipitated salts in the concentrated composition.
