No. 391 716

The present invention relates to concentrated liquid plasticizer compositions with improved pouring and water-dispersing properties, comprising - in addition to a liquid carrier and, if appropriate, additives customary for textile plasticizers - 25 to 55% by mass of an active system, consisting of a textile-substantive agent and textile-plasticizers, the textile-substantive agent a polyammonium compound of the general formula:

According to the invention, the fabric softeners are present as a binary mixture of a cationic fabric softener component and a nonionic fabric softener component.

The concentrated liquid plasticizers according to the invention provide a number of important advantages in addition to easy pourability and water dispersibility, including convenience for the consumer during transportation, storage and flexibility of use, since the housewives no longer rely on the selection of "their" degree of softness due to the capacity of the dispenser for textile plasticizers in automatic washing machines are limited. Another important aspect relates to the possibility that the consumer is now offered to either use a concentrated product as such or to use it in a suitable concentration after previous dilution.

Although it is known that concentrated fabric softening compositions can provide convenience and ease of use for the housewife, so far no technical solutions have been available to avoid known disadvantages, particularly disadvantages in terms of pourability and water dispersibility, which adhere to common products which contain more than about 10 to 12% by mass of the active material. Attempts have been made to solve these problems by using electrolytes, including calcium chloride, e.g. B. in concentrations up to 2000 ppm, were applied. However, such proposals have not led to a satisfactory solution to the problems, because the only way to achieve this is to incorporate a few percent more active substances into conventional liquid textile softeners. However, there is no solution in the prior art to make a commercially viable liquid rinse softener product containing active ingredient concentrations as contemplated by the present invention, or more generally greater than about 15%, with the physical properties and disadvantages of use set forth above are to be avoided.

DE-OS 26 22 014, 26 31 114 and 26 31 419 describe textile treatment compositions which comprise mixtures of cationic and nonionic plasticizers and cationic substantive agents, such as polyamines. The compositions proposed according to the invention with a content of 25 to 55% by mass of an active system, in which the nonionic plasticizer component must be present in a large excess in a decisive manner in comparison with the cationic plasticizer component in order to achieve satisfactory pouring behavior and satisfactory dispersibility, are not included therein. 2-

No. 391 716.

The main aim of the present invention is therefore to provide concentrated fabric softening compositions which have pourability and water dispersibility properties which are essentially with liquid softeners with usual active ingredient concentration ranges, i. H. from about 3 to about 10% by mass.

Another object of the present invention is to provide a liquid concentrated plasticizer composition, the physical aspects of which are reminiscent of conventional low activity plasticizers, and which has no phase instability or other disadvantages that may arise during prolonged storage.

The above and other objects of the present invention can now be achieved by the combined use of a textile substantive agent and a textile softener component in the defined ranges, as is evident from the following description of the invention

It has now been found that concentrated, liquid textile softeners can be produced which can give a number of favorable properties, in particular when used, and generally have economic advantages. &lt;

The active mixture is then dispersed in the aqueous base, which if necessary contains a pH regulator.

Normally, the plasticizers in question are in liquid form at 60 ° C and therefore form real emulsions in an aqueous continuous phase. During cooling, the disperse phase can solidify in whole or in part, so that the final composition is in the form of a dispersion which is not a real liquid / liquid emulsion. The term &quot; dispersion &quot; means liquid / liquid phase or solid / liquid phase dispersions and emulsions.

The following experimental information is provided to illustrate and facilitate understanding of the invention.

Example 1:

A concentrated liquid fabric softener is made which has the following composition. The glycerol monostearate is melted at 65 ° C. The ditallow alkyl dimethyl ammonium chloride and the N-tallow alkyl-N, N ', N'-tri- (2-hydroxyethyl) -l, 3-propanediamine (unneutralized) are dispersed with stirring in the molten glycerol monostearate, and so the (molten) active material premix is formed . The (active material) premix is subsequently dispersed with vigorous stirring in a water base that is at a temperature of about 60 ° C. Before adding the premix, hydrochloric acid and minor ingredients are added to the water base to adjust the pH of the liquid plasticizer composition (measured at 20 ° C) to 4.5.
