"Compositions adoucissantes concentrées" "Concentrated softening compositions"
La .présente invention concerne des compositions adoucissantes pour tissus, notamment des compositions aqueuses contenant des quantités relativement importantes d'adoucissants du type cationique, destinées à être utilisées dans le cycle de rinçage des opérations de blanchissage. Plus particulièrement, l'invention concerne des compositions aqueuses concentrées d'adoucissants cationiques dont la viscosité est ajustable et qui sont limpides et diluables à l'eau, la viscosité des compositions diluées obtenues étant ajustable. Les compositions concentrées ont une viscosité faible, permettant de les verser, et stable dans le temps, et sont susceptibles d'être diluées, notamment par de l'eau du robinet, cette eau étant à température quelconque. Les compositions diluées ainsi ob¬ tenues ont une viscosité acceptable pour la ménagère et supérieure à celle de la composition concentrée. On connaît déjà des compositions concentrées d'adoucissants cationiques, diluables à l'eau.The present invention relates to fabric softener compositions, in particular aqueous compositions containing relatively large amounts of softeners of the cationic type, intended for use in the rinse cycle of laundering operations. More particularly, the invention relates to concentrated aqueous compositions of cationic softeners whose viscosity is adjustable and which are clear and dilutable with water, the viscosity of the diluted compositions obtained being adjustable. The concentrated compositions have a low viscosity, making it possible to pour them, and stable over time, and are capable of being diluted, in particular by tap water, this water being at any temperature. The diluted compositions thus obtained have a viscosity acceptable to the housewife and greater than that of the concentrated composition. Concentrated cationic softener compositions are already known which can be diluted with water.

Ce document précise que les compo¬ sitions contiennent l'agent non adoucissant à une concentration supérieure à 33 % en poids, et l'agent adoucissant à une concentration inférieure à la concentration de l'agent non adoucissant. Les compositions décrites contiennent de 25 % à 12,5 % de chlorure de dialkyldimethylammonium ou 12,5 % de chlorure de dialkylméthyléthoxyammonium adoucissant et environ de 33 % à 50 % de chlorure d'alkyldimethylbenzylammonium non adoucissant. Le but poursuivi selon cette publication est d'obtenir des compositions transparentes.Document FR-A-2 51 960 describes compositions containing a softening agent which is a dialkyldimethylammonium chloride or a dialkylmethylethoxyammonium chloride in admixture with a non-softening agent which is an alkyldimethylbenzylammonium chloride, isopropyl alcohol and 'water. This document specifies that the compositions contain the non-softening agent at a concentration greater than 33% by weight, and the softening agent at a concentration lower than the concentration of the non-softening agent.

The aim of this publication is to obtain transparent compositions.
Cependant, de telles compositions sont chères et d'une efficacité limitée, puisqu'elles contiennent une quantité importante d'agent cationi¬ que non adoucissant.However, such compositions are expensive and of limited effectiveness, since they contain a large amount of cationic agent that is non-softening.
Le document FR-A-2 540 901 décrit des compositions contenantDocument FR-A-2 540 901 describes compositions containing
- de 15 à 50 % de sels de dialkyldimethylammonium,- from 15 to 50% of dialkyldimethylammonium salts,

In the examples, it is always mentioned that such compositions contain a nonionic hydrophilic solubilizing agent.
Cependant, les compositions concentrées décrites dans ces publi¬ cations ont pour inconvénient de donner par dilution des compositions très fluides et peu visqueuses.

Ces compositions sont présentées comme stables même aux températures basses ou élevées. Elles peuvent être complétées, en option, par des proportions secondaires, à savoir entre 0,5 et 10 %, d'autres ingrédients parmi lesquels figurent des aicanols inférieurs. Les compositions de ce type ne sont pas limpides et ont une viscosité qui croît avec le temps, au cours du stockage.However, the concentrated compositions described in these publications have the drawback of giving very dilute, low-viscosity compositions by dilution.

Les compositions ainsi formées ne sont pas limpides.Document EP-A-60 003 describes concentrated softening compositions for fabrics comprising 8 to 22% of a cationic softener 0.6 to 3% of at least one water-soluble polyalkoxylated ammonium salt and 0.2 to 5% of 'a fatty acid ester of a polyoi.

These compositions comprise 30 to 60% of a cationic softening agent, 5 to 20% of a include 30 to 60% of a cationic softening agent, 5 to 20% of a cationic disinfectant, 5 to 20% of a nonionic dispersant and 15 to 0% of lower alkanols. It is expressly stated that the presence of non-ionic dispersants is essential for the concentrated product to disperse well in cold water.
Le document EP-A- 0 562 décrit des compositions concentrées d'adoucissants contenant un agent adoucissant cationique et un agent non ionique dans un rapport compris entre 10/1 et 3/2, de l'alcool et de l'eau ; l'objectif est l'obtention de compositions d'adoucissant, concen- trées, diluables à l'eau froide ou tiède.Document EP-A-0 562 describes concentrated softener compositions containing a cationic softening agent and a nonionic agent in a ratio of between 10/1 and 3/2, alcohol and water; the objective is to obtain softener compositions, concentrated, which can be diluted with cold or lukewarm water.
Or, les ménagères qui diluent avec de l'eau du robinet de telles compositions, concentrées pour préparer des compositions diluées à stocker avant emploi, préfèrent obtenir des compositions diluées ayant un aspect visqueux. Mais la température de l'eau du robinet varie. Ainsi, elle peut varier entre +5 et +25°C. On a constaté que lorsque la température de l'eau est de l'ordre de +5°C, la viscosité des compositions diluées est alors trop élevée, et lorsque la ménagère verse la composition diluée dans un bac prévu à cet effet dans une machine automatique à laver le linge, la composition diluée, du fai de sa viscosité importante, et de sa tendance à former des floculats, peut boucher la canalisation d'ame¬ née de la composition adoucissante dans le bac de rinçage. En outre, la dispersion de la composition diluée dans l'eau de rinçage se fait plus difficilement quand la composition concentrée est diluée avec de l'eau froide, par exemple ayant une température de +5°C environ. L'invention vise à pallier ces inconvénients.However, housewives who dilute with tap water such compositions, concentrated to prepare diluted compositions to be stored before use, prefer to obtain diluted compositions having a viscous appearance. But the temperature of tap water varies. Thus, it can vary between +5 and + 25 ° C. It has been found that when the water temperature is of the order of + 5 ° C., the viscosity of the diluted compositions is then too high, and when the housewife pours the diluted composition into a container provided for this purpose in a machine. automatic washing machine, the diluted composition, the weakness of its high viscosity, and its tendency to form flocculates, can clog the amine pipe of the softening composition in the rinsing tank. In addition, the dispersion of the composition diluted in rinsing water is more difficult when the concentrated composition is diluted with cold water, for example having a temperature of approximately + 5 ° C. The invention aims to overcome these drawbacks.
Les problèmes à résoudre sont les suivants : Obtention d'une composition adoucissante concentrée en agents adoucis¬ sants :The problems to be solved are as follows: Obtaining a softening composition concentrated in softening agents:
- limpide et stable au stockage entre -15 et +40°C, - diluable à l'eau de ville, même froide,- clear and stable in storage between -15 and + 40 ° C, - dilutable with tap water, even cold,
- contenant une quantité d'alcool la plus faible possible,- containing as little alcohol as possible,
- ayant une viscosité faible, permettant de la verser et stable dans le temps, et- having a low viscosity, making it possible to pour it and stable over time, and
- donnant une composition diluée, stable au stockage, et dont la viscosité soit acceptable pour la ménagère et supérieure à celle de la composition concentrée.- giving a diluted composition, stable in storage, and whose viscosity is acceptable to the housewife and greater than that of the concentrated composition.
Aucun des documents de la technique antérieure n'a décrit ou
suggéré ce problème de viscosité des compositions diluées, suffisamment élevée pour être acceptée par l'utilisateur, mais suffisamment faible pour pouvoir s'écouler dans des conduites de machines à laver le linge, ces compositions ayant une structure physique homogène et ne formant pas d'agglomérats pouvant boucher les conduites et étant facilement dispersables dans l'eau de rinçage.None of the prior art documents has described or suggested this problem of viscosity of the diluted compositions, high enough to be accepted by the user, but low enough to be able to flow through the lines of washing machines, these compositions having a homogeneous physical structure and not forming agglomerates which can clog the pipes and are easily dispersible in the rinsing water.
La présente invention fournit des compositions concentrées, limpides, d'adoucissants pour tissus qui peuvent être diluées par de l'eau froide sans former de particules ou agglomérats susceptibles de boucher les conduites de faible diamètre et qui sont stables au stockage, tant à l'état concentré qu'à l'état dilué.The present invention provides concentrated, clear, fabric softener compositions which can be diluted with cold water without forming particles or agglomerates capable of clogging small diameter pipes and which are stable in storage, both in concentrated state than diluted state.

Sans vouloir être lié par une quelconque théorie, on pense que le composant B permet, en combinaison avec le solvant C, de fluidifier et de rendre limpide la composition ; en outre l'apport de composant B permet de réduire la teneur en solvant C, mais dans une certaine mesure 25 seulement, car une trop grande proportion de composant B exercerait un effet non souhaité d'abaissement de la viscosité de la composition diluée.Without wishing to be bound by any theory, it is believed that component B makes it possible, in combination with solvent C, to fluidize and make the composition clear; moreover, the addition of component B makes it possible to reduce the content of solvent C, but only to a certain extent, since too large a proportion of component B would exert an undesired effect of lowering the viscosity of the diluted composition.

En fonction de la température de l'eau de dilution, on obtient des compositions diluées dont les viscosités sont données dans le tableau 1.Water qs 100 96 This concentrated composition is diluted with three times its volume of water. The viscosities are measured with a Brookfield viscometer, mobile 1, at 6 revolutions / minute. Depending on the temperature of the dilution water, dilute compositions are obtained, the viscosities of which are given in Table 1.

On voit donc que les compositions selon l'invention ont une visco¬ sité supérieure à 100 mPa.s pour des températures d'eau de dilution infé¬ rieures à 20°C. Or, une viscosité supérieure ~k 100 mPa.s, de préférence 100-200 mPa.s, est une viscosité qui est perçue par la ménagère comme l'indice d'un .produit efficace. Exemple 6It can therefore be seen that the compositions according to the invention have a viscosity greater than 100 mPa.s for dilution water temperatures lower than 20 ° C. However, a viscosity greater than ~ 100 mPa.s, preferably 100-200 mPa.s, is a viscosity which is perceived by the housewife as the index of an effective product. Example 6
On étudie l'Influence du rapport en poids de la quantité d'agent adoucissant A à la quantité de composé cationique non adoucissant B. On réalise les compositions suivantes :The influence of the weight ratio of the quantity of softening agent A to the quantity of non-softening cationic compound B is studied. The following compositions are produced:

(B) ODHMAC(B) ODHMAC
(C) Isopropanol Parfum 1 % Eau q.s.p. 100 %(C) Isopropanol Perfume 1% Water q.s.p. 100%
On fait varier les quantités d'agent A, d'agent B et d'isopropanol, la quan¬ tité de parfum étant toujours égale à 1 % en poids de la composition. On dilue à l'eau à 20°C ces compositions pour obtenir des composi¬ tions diluées contenant 5 % en poids d'agent adoucissant A. On mesure les viscosités des compositions diluées ainsi obtenues, au viscosimètre Brookfield, mobile 1, vitesse 6 tours/minute. On obtient les résultats suivants (cf. tableau 2) :
Tableau 2The quantities of agent A, agent B and isopropanol are varied, the quantity of perfume always being equal to 1% by weight of the composition. These compositions are diluted with water at 20 ° C. to obtain diluted compositions containing 5% by weight of softening agent A. The viscosities of the diluted compositions thus obtained are measured, with a Brookfield viscometer, mobile 1, speed 6 turns /minute. The following results are obtained (cf. table 2): Table 2

A, la viscosité de la composition diluée à 5 % de composé adoucissant est faible. Au contraire, lorsqu'on a ajouté très peu d'agent non adoucissantA, the viscosity of the composition diluted with 5% of softening compound is low. On the contrary, when very little non-softening agent has been added
B, par exemple de 100 à 400 fois moins pour la quantité d'agent adoucissant A, les viscosités des compositions diluées contenant 5 % en poids d'adoucis¬ sant A sont comprises entre 100 et 160 mPa.s.B, for example from 100 to 400 times less for the amount of softening agent A, the viscosities of the diluted compositions containing 5% by weight of softening agent A are between 100 and 160 mPa.s.

1 % de parfum, q.s.p. 100 % d'eau.1% perfume, q.s.p. 100% water.
La composition obtenue a une viscosité lui permettant d'être versée. Cette composition est diluée avec trois fois son volume d'eau, l'eau étant à 10°C ou 20°C. On obtient alors une composition diluée qui forme des grumeaux et dont la viscosité est très élevée : / 1000 mPa.s (mesurée au viscosimètre Brookfield, mobile n° 1 , 6 tours/-
minute). b) On réalise la composition concentrée suivante : 16 % de DOIMMS, 4 % d'ODHMAC, 11 96 d'isopropanol,The composition obtained has a viscosity allowing it to be poured. This composition is diluted with three times its volume of water, the water being at 10 ° C or 20 ° C. A diluted composition is then obtained which forms lumps and whose viscosity is very high: / 1000 mPa.s (measured with the Brookfield viscometer, mobile n ° 1, 6 turns / - minute). b) The following concentrated composition is produced: 16% DOIMMS, 4% ODHMAC, 11% isopropanol,
1 % de parfum, q.s.p. 100 96 d'eau. On dilue cette composition avec trois fois son volume d'eau, la température de l'eau de dilution étant de 10°C. La viscosité de la composition diluée est de 10 mPa.s (mesurée de la même manière que pour l'exemple 4a).1% perfume, q.s.p. 100 96 of water. This composition is diluted with three times its volume of water, the temperature of the dilution water being 10 ° C. The viscosity of the diluted composition is 10 mPa.s (measured in the same way as for Example 4a).
On voit donc que la fonction technique de l'agent cationique non adoucissant est différente de la fonction technique de l'agent non ionique. Selon la quantité d'agent cationique non adoucissant dans la compo¬ sition concentrée, on peut régler la viscosité de la composition diluée à une valeur acceptable pour la ménagère, (comprise de préférence entre 50 et 900 mPa.s).It can therefore be seen that the technical function of the non-softening cationic agent is different from the technical function of the nonionic agent. Depending on the amount of non-softening cationic agent in the concentrated composition, the viscosity of the diluted composition can be adjusted to a value acceptable to the housewife (preferably between 50 and 900 mPa.s).
En effet les exemples 3b et 4b montrent que, pour une composition contenant environ 15 % d'agent adoucissant A et 0,1 % d'agent non adoucis¬ sant B, la viscosité de la composition diluée est de 160 mPa.s, alors que pour une composition contenant 4 96 d'agent non adoucissant B, la viscosité de la composition diluée est de 10 mPa.s.Indeed, Examples 3b and 4b show that, for a composition containing approximately 15% of softening agent A and 0.1% of non-softening agent B, the viscosity of the diluted composition is 160 mPa.s, then that for a composition containing 496 of non-softening agent B, the viscosity of the diluted composition is 10 mPa.s.
En outre, lorsqu'on disperse dans de l'eau froide les compositions diluées 4a et 4b obtenues à partir des compositions concentrées, on voit que la composition diluée 4a se disperse très difficilement et qu'il faut agiter à la main pendant quelques dizaines de secondes pour obtenir une bonne dispersion dans l'eau. Au contraire, la composition diluée 4b se disperse très facilement dans de l'eau à 10°C (en moins de 5 secondes). Exemple 8In addition, when the diluted compositions 4a and 4b obtained from the concentrated compositions are dispersed in cold water, it can be seen that the diluted composition 4a is very difficult to disperse and that it is necessary to shake by hand for several tens of seconds to obtain good dispersion in water. On the contrary, the diluted composition 4b disperses very easily in water at 10 ° C (in less than 5 seconds). Example 8
