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 surfactants (most often quaternary ammonium compounds comprising at least 2 long alkyl chains), or mixtures in variable proportions of cationic surfactants and nonionic surfactants than l '' 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 it 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.
• the object of the present invention is to remedy these 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 city 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 homogeneous stable solution and of a consistency identical to that of the products.
• the product which they usually use namely a homogeneous stable solution and of a consistency identical to that of the products.
• commercially available 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 by example, a product perfectly suited to the dimensions of the softener tanks of washing machines 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 is characterized in that it is composed of active softening agents constituted by one or more specific cationic softening agents, representing 15 to 30% of the weight of the total composition, and one or more non-ionic agents acting as an emulsifying or stabilizing agent for the cationic agent (s), and if necessary, additives such as perfumes, perfume emulsifying agents, colorants and optical brighteners, preservatives as well as one or more solvents of the methanol, ethanol, isopropanol or glycol type.

• ville a solution of stability and homogeneity comparable to conventional solutions and even having properties improved softeners and improved absorbency compared to the prior art.
• 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 that 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 further dilution.
• the usual capacities range, for example, from 50 to 500 cm 3 for a subsequent dilution bringing the volume to 1000 cm.
• the user transports in a 250 cm 3 packaging as much softening power as in a 1000 cm 3 bottle bought 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.
