Definitions

  • the present invention relates to a concentrated softening composition for textile fibers.
  • the softening compositions generally consist of 3 to 10% of active softening agents and 90 to 97% of demineralized water.
  • the active softening agents are generally either cationic surfactant compounds (most often quaternary ammonium compounds comprising at least 2 long alkyl chains), or mixtures in variable proportions of cationic surfactants and surfactants non-ionic active agents which are combined with additional additives such as perfumes, optical brighteners, colorants, preservatives, bactericides, thickening agents, etc.
  • compositions have the drawback of being unable to be manufactured and marketed only in the very diluted state as has been shown, a concentration greater than 10% transforming them into gels which are not dispersible in water when they are used by housewife.
  • the industrial-manufacturer is obliged to use demineralized water for the manufacture of its product, the electrolytes of which have been practically eliminated, in order to obtain an emulsion having acceptable homogeneity, stability and consistency at the time of use.
  • document FR-A-2 295122 describes a softener-disinfectant composition for textiles which requires to be effective to have a high content of two different types of cationic agents, one of which is a softener and the other a disinfectant; the total of the cationic agents then represents 35 to 80% by weight of the composition.
  • Document US-A-4 140 641 describes a mixed detergent softening composition, aiming to combine in a single formula a nonionic detergent agent and a cationic softener component; in such a composition, the nonionic agent must predominate and the cationic agent must be a compound of imidazolinium type. An agent of quaternary ammonium type is expressly excluded from such a composition.
  • the object of the present invention is to remedy the above-mentioned drawbacks by proposing a concentrated softening composition which is not in the form of a non-dispersible gel but in the form of a stable viscous solution which is completely dilutable in tap water, even cold. , therefore water which does not need to be demineralized beforehand.
  • the user finds, after dilution in tap water and by simple stirring, the product which they usually use, namely a stable homogeneous solution and of a consistency identical to that of existing products commercially, that is to say products sold by the manufacturer in the form of a dilute and viscous solution.
  • the concentrated product according to the invention can therefore give, by simple dilution, in tap water for example, a product perfectly suited to the dimensions of the softener tanks of washing machines for laundry currently on the market.
  • the product according to the invention is designed, unlike diluted softeners on the market, for washing machines of recent design, provided with a softener tank capable of ensuring a reserve of product for 1 at 2 months to facilitate the housewife's work.
  • the product of the invention has 2 essential qualities for such machines: a high concentration which allows the use of a tank of relatively small dimensions, therefore easier to accommodate in such machines and prolonged stability to the cycles of temperature in the washing machine tank. These qualities also make it usable in industrial washing machines.
  • the composition according to the invention comprises an active cationic softening agent as well as at least one nonionic emulsifying agent and one or more solvents chosen from methanol, ethanol, isopropanol and solvents of glycol type and water, characterized in that it constitutes after dilution with water a homogeneous stable solution usable as a softening composition for textile fibers; that it comprises 15 to 30% by weight relative to the total weight of the composition of said cationic softening active agent consisting of at least one quaternary ammonium compound, having the formula: in which R1 and R2 represent, independently of one another, alkyl groups having 10 to 22 carbon atoms and interrupted by carboxy or ethoxy functional groups, R3 and R 4 are alkyl or hydroxy alkyl groups having from 1 with 4 carbon atoms, and X represents a halide, methylsulfate or ethylsulfate anion and that the weight ratio of cationic agents to nonionic agents
  • the invention is based on the development of a composition having a concentration of active agents which is approximately four to six times greater than the concentration of the compositions currently on the market and capable of giving after dilution in water.
  • city a solution of stability and homogeneity comparable to conventional solutions and even having improved softening properties and improved absorbency compared to the prior art.
  • compositions having a viscosity which allows easy and homogeneous dilution it can be diluted 3 to 10 times and preferably 4 to 6 times with cold tap water and finally present itself in the same aspect as the usual products and therefore, be used in the same way in washing machines. classic type, and for use when washing by hand.
  • the concentrated product can be packaged either in rigid plastic packaging or in flexible plastic packaging.
  • this packaging is an intermediate packaging, since the product must be diluted before use. It is therefore more advantageous to use flexible plastic packaging in the form of a dose or for example a container, because the flexible plastic container can be completely emptied of the product it contains by pressing the walls against each other , while the hard plastic packaging should be rinsed to be completely emptied.
  • Another advantage of this kind of packaging is that it takes up less space for storage, since the space required for storing doses is 1.4 times the volume of the dose whereas for storing hard plastic packaging, the he space required is 2 to 2.5 times the volume of the product contained in the packaging, depending on the shape of the latter. Shaping flexible plastic packaging is much less expensive than shaping hard plastic packaging.
  • the use of the product is done from a bottle in which the product is diluted, and this bottle can be reused many times.
  • the volume of the flexible packaging can be adapted to the desired subsequent dilution.
  • the usual capacities range, for example, from 50 to 500 cm 3 for a subsequent dilution bringing the volume to 1000 cm3.
  • the user transports in a 250 cm3 packaging as much softening power as in a 1000 cm 3 bottle purchased commercially.
  • the product sold in this type of packaging offers all guarantees to the user, who, after the first dilution with tap water, obtains a homogeneous dispersion, stable during storage, and of comparable viscosity to that of products sold in diluted form.
  • the compound / water / solvent ratio is calculated so as to obtain a product which can be packaged in doses, the viscosity of which is calculated to allow the dose to be filled and emptied quickly, easily and completely.
  • the user can transfer the product into a 1 liter bottle, then top up with tap water which must not present a special quality and, after shaking the bottle, obtain a ready-to-use product for use by hand or for machine use.
  • the product thus obtained has a usual viscosity for the user, which allows him to distribute the adequate quantity of product constantly.
  • the main constituent is therefore the cationic surfactant (s) which can be constituted by different quaternary ammonium compounds of general formula: formula in which R1 and R 2 represent, independently of one another, alkyl groups having from 10 to 22 carbon atoms and interrupted by carboxy, amide or ethoxy functional groups; R3 and R 4 represent alkyl or hydroxyalkyl groups having from 1 to 4 carbon atoms, and X is an anion: halide, methylsulfate or ethylsulfate.
  • R1 and R 2 represent, independently of one another, alkyl groups having from 10 to 22 carbon atoms and interrupted by carboxy, amide or ethoxy functional groups
  • R3 and R 4 represent alkyl or hydroxyalkyl groups having from 1 to 4 carbon atoms
  • X is an anion: halide, methylsulfate or ethylsulfate.
  • di (stearoyl-oxyethyl-) dimethyl ammonium chloride di- (lauryl-hydroxypropyl-) dimethyl ammonium chloride, di (stearoyl-oxyethyl- methylsulfate) dimethyl ammonium, di (palmytoyl-oxyethyl) dimethyl ammonium chloride, di (stearoyl-oxyethyl-) hydroxy-ethyl-methyl-ammonium methyl sulphate, di (palmitoyl-oxyethyl-) hydroxy-ethyl-methyl-methyl ammonium methyl sulphate di (oleoyloxyethyl-) hydroxyethyl-methyl ammonium methyl sulfate, di (stearoyl-oxyethyl-) hydroxyethyl-methyl ammonium ethyl sulfate, di (palmitoyl-)
  • the compounds preferably used are di (stearoyl-oxyethyl-) methyl-hydroxyethyl ammonium methylsulfates, di (palmitoyl-oxyethyl-) methyl-hydroxyethyl ammonium methylsulfates, and di (oleoyl methylsulfates) -oxyethyl-) methyl-hydroxyethyl ammonium, alone or as a mixture.
  • the nonionic agent or agents are chosen from the group formed by fatty alcohols containing from 8 to 20 carbon atoms condensed with 3 to 12 molecules of alkylene oxide (preferably ethylene and / or propylene) and alkylphenols comprising an alkyl radical having 8 to 10 carbon atoms condensed with 4 to 12 molecules of alkylene oxide (preferably ethylene and / or propylene).
  • compositions containing a specific cationic supplemented with one or more suitable nonionics are due to a composition containing a specific cationic supplemented with one or more suitable nonionics. After a first dilution with cold city water, a dispersion of homogeneity and physical stability is obtained which has never been obtained in the prior art, which is essential for packaging a concentrated product. , in the form of a plastic dose, the price of which is very low compared to the packaging of the prior art.
  • this composition remains stable within very wide temperature limits ranging from those which can be reached in the storage tank of washing machines during washing and can, moreover, withstand a storage temperature of up to _25 ° C while regaining its initial consistency after thawing.
  • oils in water are added to the composition of the emulsifying agents having an HLB value of between 10 and 16, belonging to the class of nonionics; such agents are preferably sorbitan esters and / or poly-oxyethylenated sorbitan esters.
  • composition of the present invention it has been found that the addition of a very small amount of these products makes it possible to obtain incorporation of the perfumes without subsequent phase separation and stability over a long shelf life.
  • a solvent or a mixture of solvents chosen from methanol, ethanol, isopropanol and solvents of the glycol type and of water is necessary for the viscosity adjustment and to obtain a very homogeneous and finely dispersed emulsion.
  • compositions which are the subject of the invention will be demonstrated by referring to the following tests, in which the softening properties of these compositions are compared with those of a usual product based on hydrogenated di-tallow chloride. methyl ammonium.
  • compositions which have a good softening power have the drawback of rendering the fabrics hydrophobic, that is to say that the fabrics lose part of their absorbing power, which is unpleasant, in particular for terry towels whose main function is to absorb water.
  • Example 1 is repeated, in which 5 g of oxyethylenated nonylphenol are added, before the addition of the mixture of perfume and oxyethylenated sorbitan ester. An opaque and homogeneous composition is obtained, the viscosity of which is between 100 and 200 millipascals.second.
  • Example 1 is used again and 5 g of a C IEX-C 14 fatty alcohol oxyethylenated with 9 molecules of ethylene oxide are added, and the procedure is as in Example 2.
  • a product is obtained whose viscosity is 200 to 300 millipascals.second and whose softening properties are identical to those of Example 2.
  • Example 3 is repeated, and 10 g of oxyethylenated C12-C 14 fatty alcohol are added and the procedure is as in Example 3.
  • a composition is obtained having a viscosity of between 700 and 900 millipascals.second. This composition is very difficult to pour and the dilution in tap water is very difficult, very vigorous stirring is necessary to obtain a homogeneous dilute solution.
