More specifically, the invention relates to concentrated aqueous compositions of cationic softeners whose viscosity is adjustable and which are clear and capable of being diluted with water, the viscosity of the diluted compositions obtained being adjustable. The concentrated compositions have a viscosity which is low, making it possible to pour them, and durable, and are capable of being diluted, especially with tap water, which water may have any temperature. The diluted compositions thus obtained have a viscosity which is acceptable to the housewife and greater than that of the concentrated composition.
Concentrated compositions of cationic softeners which can be diluted with water are already known.
French document A-2,451,960 describes compositions containing a softening agent which is a dialkyldimethylammonium chloride or a dialkylmethylethoxyammonium chloride mixed with a non-softening agent which is an alkyldimethylbenzylammonium chloride, and containing isopropyl alcohol and water. This document states that the compositions contain the non-softening agent in a concentration which is higher than 33% by weight and the softening agent in a concentration which is lower than the concentration of the non-softening agent. The compositions described contain from 25% to 12.5% of dialkyldimethylammonium chloride or 12.5% of softening dialkylmethylethoxyammonium chloride and from about 33% to 50% of non-softening alkyldimethylbenzyl- Sammonium chloride. The purpose aimed at according to this publication is to obtain transparent compositions.
However, such compositions are expensive and have a limited efficiency, because they contain a large quantity of non-softening cationic agent.
French document A-2,540,901 describes compositions containing from 15 to 50% of dialkyldimethylammonium salts, i rii I
I
2 from 10 to 50% of hydrophilic solvents, the weight ratio between the solvents and the dialkyldimethylammonium salts being between 0.7 and 2.3.
These compositions may optionally contain solubilizing aids which are, for example, hydrophilic nonionic surfactants. The compositions are intended to be diluted with water.
The purpose aimed at according to this document is to obtain concentrated softener compositions which can be diluted with cold or luke-warm water. In the examples it is always mentioned that such compositions contain a nonionic hydrophilic solubilizing agent.
However, the concentrated compositions described in these publications have the disadvantage that, by dilution, they provide compositions which are very fluid and scarcely viscous.
French document A-2,523,606 describes concentrated fabric-softening compositions comprising from 8 to 20% of I a softener of the imidazolinium type and from 0.5 to 5% of i 20 an either conventional or dicationic quaternary ammonium compound. These compositions are presented as being stable even at low or high temperatures. They may optionally be supplemented by secondary proportions, namely of between i 0.5 and 10%, of other ingredients, among which are lower alkanols. The compositions of this type are not clear and have a viscosity which increases with time, during storage.
i European document A-60,003 describes concentrated I fabric-softening compositions comprising from 8 to 22% of a cationic softener, from 0.6 to 3% of at least one watersoluble polyalkoxylated ammonium salt and from 0.2 to 5% of y a fatty acid ester of a polyol. The object aimed at is to obtain stable compositions whose viscosity does not substantially vary, even at high temperature and over long periods of storage. The thus formed compositions are not clear.
European document A-199,382 describes softening compositions which, so as not to lose their effectiveness when they are brought into contact with the anionic or nonionic r 3 detergents contained in washing products, comprise from 3 to 35% of a mixture of: 10-92% of the product of the reaction of higher fatty acids with a selected polyamine, 8-90% of cationic nitrogenous salts having a single long acyclic aliphatic chain having from 15 to 22 carbon atoms, and 0-80% of cationic nitrogenous salts having at least two chains of this type or one chain of this type and an arylalkyl ring.
French document A-2,295,122 describes concentrated fabric-softening compositions which are stable with regard to temperature, do not jellify and have a disinfectant action. These compositions comprise from 30 to 60% of a cationic softening agent, from 5 to 20% of a cationic disinfectant, from 5 to 20% of a nonionic dispersing agent and from 15 to 40% of lower alkanols. It is expressly stated that the presence of nonionic dispersing agents is essential for the concentrated product to disperse properly in cold water.
European document A-40,562 describes concentrated softener compositions containing a cationic softening agent and nonionic agent in a ratio of between 10/1 and 3/2, alcohol and water; the object is to obtain concentrated softener compositions which are capable of being diluted with cold or luke-warm water.
Housewives who dilute such concentrated compositions with tap water in order to prepare diluted compositions to be stored prior to use prefer to obtain diluted compositions having a viscous appearance. But the temperature of the tap water varies. Thus, it may vary between +5 and +25 0 C. It has been found that, when the water temperature is of the order of +5 0 C, the viscosity of the diluted compositions is too high and when the housewife pours the diluted composition into a trough provided for this purpose in an automatic washing machine, the diluted composition, due to its high viscosity and its tendency to form flocculates, may block the duct taking the softening composition to the rinsing trough. Moreover, the dispersion of the diluted compositicn in the rinsing water is more difficult when the
I
V4 concentrated composition is diluted with cold water, for example having a temperature of about +5 0
C.
The invention is aimed at overcoming these drawbacks.
The problems to be solved are as follows: Obtaining a softening composition with concentrated softening agents which: is clear and stable during storage between -15 and 0
C,
is capable of being diluted with town water, even when cold, contains the lowest possible quantity of alcohol, has a viscosity which is low, allowing it to be poured, and durable, and provides a diluted composition which is stable during storage and whose viscosity is acceptable to the housewife and higher than that of the concentrated composition.
None of the prior art documents has described or hinted at this viscosity problem of the diluted compositions, high enough to be accepted by the user, but low enough to be able to flow through the pipes of washing machines, which compositions have a homogeneous physical structure and do not form agglomerates which may block the pipes, and are readily dispersable in the rinsing water.
I The present invention provides concentrated, clear fabric-softening compositions which may be diluted with i cold water without forming particles or agglomerates capable of blocking the small-diameter pipes and which are stable during storage, both in the concentrated and in the diluted state.
The invention relates to a concentrated textilesoftening composition capable of being diluted with water, characterized in that it contains: a) from 10 to 50% by weight of at least one softening agent A, selected from among quaternary ammonium salts having at least two long alkyl chains having from 8 to 22 carbon atoms, possibly interrupted by an ester, ether or amide group; imidazolinium salts; and products from the i reaction of fatty acids with polyamines selected from the i

To prepare the compositions according to the invention, one can simply: in the case of ingredients which are liquid at ambient temperature, mix these cold in any order, in case one of the ingredients is not liquid at ambient temperature, heat this ingredient to cause it to melt and add the other ingredients to the molten mass obtained, observing the precautions of use, and preferably adding the solvent C first and water last.

In these examples, all percentages are given by weight in relation to the weight of the total composition. The percentages given refer to the active material, without taking S into account the solvents usually present in the commercial products containing them.

The concentrated composition is stable at ambient temperature and at 40°C for more than a year. At -15 0 C, the concentrated composition assumes the consistency of a gel, which is however rather fluid and which disappears to revert i 35 to a completely fluid composition after returning to ambient temperature.

It is stable and has a viscosity (measured on the Brookfield viscosimeter with a No 2 rotor, at 12 rpm) of 40 mPa.s after 1 day and 30 mPa.s after 1 month. After adding three times its volume of tap water to this composition, a stable diluted composition is obtained whose viscosity (measured on the Brookfield viscosimeter with a N° 1 rotor, at 6 rpm) is 549 mPa.s after 1 day and 900 mPa.s after 1 month.
14 Example 4 The following composition is obtained by mixing: DOIMMS(*) 50 ODHMAC 10 Isopropanol 3.34% Perfume 0.97% Dye solution) 0.8 Water quantity enough for 100% l-oleylamidoethyl-2-oleylimidazolinium methosulfate sold under the name REWOQUAT W-3690 by the Company REWO.
The composition obtained is fluid and clear. Its viscosity (measured on the Brookfield viscosimeter with a NO 2 rotor, at 12 rpm) is 30 mPa.s after 4 days. After adding nine times its volume of tap water to this solution, a diluted composition is obtained whose viscosity (measured on the Brookfield viscosimeter with a N o 1 rotor, at 6 rpm) is 132 mPa.s after 4 days.
Example The influence of the temperature of the water with which a concentrated composition is diluted on the viscosity of the diluted composition is studied.
The following compounds are mixed: DOIMMS ODHMAC 2% Isopropanol Perfume 1% Water quantity enough for 100% This concentrated composition is diluted with three times its volume of water. The viscosities are measured with a Brookfield viscosimeter with a No 1 rotor, at 6 rpm.
As a function of the temperature of the diluting water, diluted compositions are obtained whose viscosities are given in Table 1.

r~ t' 1 Table 1 Temperature of Viscosity of the diluting water 0 C) diluted compositions (mPa.s) 180-200 20 75-100 25- 15- It can be seen, therefore, that the compositions according to the invention have a viscosity greater than 100 mPa.s for temperatures of diluting water of less than Now, a viscosity higher than 100 mPa.s, preferably 100-200 mPa.s, is a viscosity which is seen by the housewife as the mark of an effective product.
Example 6 The influence of the weight ratio between the quantity of softening agent A and the quantity of non-softening cationic compound B is studied.
The following compositions are prepared:
DOIMMS
ODHMAC
Isopropanol Perfume 1% Water quantity enough for 100% The 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 of 20 0 C to obtain diluted compositions containing 5% by weight of softening agent A. The viscosities of the diluted compositions thus obtained are measured on the Brookfield viscosimeter with a No 1 rotor, at a speed of 6 rpm. The following results are obtained (cf. Table 2): 16 Table 2 3b 3c 3d 3e 3f 3g Example 3a A 15 15 20 20 30 30 B 17 0.1 11 2 32 0.1 0.1 C 5 20 6.7 17 10 15 Ratio A/B 0.88 150 0.90 10 0.93 300 400 mPa.s 0 160 0 100 0 130 140 Viscosity of the diluted composition It can be seen, therefore, that when the percentage by weight of non-softening compound B is greater than the percentage by weight of softening compound A, the viscosity of the diluted composition containing 5% of softening compound is low. In contrast, when very little non-softening agent B has been added, for example 100 to 400 times less for the quantity of softening agent A, the viscosities of the diluted compositions containing 5% by weight of softener A are between 100 and 160 mPa.s.
Example 7 The influence of a cationic non-softening agent in an aqueous composition of softening agent is studied, at equal concentrations, compared to the influence of a nonionic agent.
a) The following concentrated composition is prepared: 16% of N-methyl-N,N-di(P-C 14
-C
18 acyloxyethyl)N-phydroxyethylammonium methylsulfate sold under the name STEPANTEX Q 185 by the company STEPAN EUROPE, 11% of isopropyl alcohol 4% of a mixture of nonionic surfactant and likewise nonionic emulsifier, 1% of perfume, quantity enough for 100% of water.
The composition obtained has a viscosity allowint it to be poured. This composition is diluted with three times its volume of water, the water having a temperature of 10 0
C
or 20°C. A diluted composition is thus obtained which forms lumps and whose viscosity is very high: L J 17 1000 mPa.s (measured on the Brookfield viscosimeter, with a No 1 rotor, 6 rpm).
b) The following concentrated composition is prepared: 16% of DOIMMS, 4% of ODHMAC, 11% of isopropanol, 1% of perfume, quantity enough for 100% of water.
This composition is diluted with three times its volume of water, the temperature of the diluting water being 10 0
C.
The viscosity of the diluted composition is 10 mPa.s (measured in the same manner as for Example 4a).
Thus, it can 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 quantity of cationic non-softening agent in the concentrated composition, the viscosity of the diluted composition can be adjusted to a value which is acceptable to the housewife (preferably between 50 and 900 mPa.s).
In fact, 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, whereas for a composition containing 4% of non-softening agent B, the viscosity of the diluted composition is 10 mPa.s.
Moreover, when the diluted compositions 4a and 4b obtained from the concentrated compositions are dispersed in cold water, it is seen that the diluted composition 4a is dispersed with great difficulty and that it is necessary to stir by hand for several dozen seconds to obtain a good dispersion in water. In contrast, the diluted composition 4b is dispersed very easily in water at 10 0 C (in less than seconds).
18 Example 8 The following composition is prepared: of DSHPM-AC, 2% of ODHMAC, 13% of 1,2-propyleneglycol, !i 11% of isopropanol, 1% of perfume, quantity enough for 100% of water.
This composition is diluted with three times its volume of water. The temperature of the diluting water is 100C.
A stable diluted composition is obtained whose viscosity, measured in the same manner as in the previous j examples, is 260 mPa.s.
