Field of application of the invention

The invention relates to v / poor and Kaltwasserverdünn bare fabric softener concentrates, which are also suitable as a refill for original bottles ready-fabric softener.

known technical solutions

To counteract the hardening of the handle washed textiles after drying, so-called fabric softeners are added to the last rinse. These are aqueous dispersions of quaternary ammonium compounds with emulsifiers, Duftkcisponenten and dyes. In the formulation of such products is a

certain minimum dilution is sought to achieve complete dispersion of the ingredients in cold water. The water content of such fabric softeners is usually in the range of 85 to 95 %. The most well-known active ingredients are dialkyldimethylammonium chlorides and quaternary imidazolinium salts (J. Amer. Oil Chemist's Soc. £ 5, 118-121 (1978)). In addition to the known softening effect, they also exhibit good antistatic properties Properties. Their use in fabric softeners, however, requires the availability of long-chain dialkylamines or ethylenediamine and long-chain alkylamines for drug synthesis. However, the quaternary active compounds mentioned have the disadvantage that their formulation must take place in high dilution and only in this way is a uniform application and distribution of the softening agent on the textile material achieved when it is used in the rinsing bath. A formulation in concentrate form with water contents below 85 % gives rise to products whose Kaltbzw. Hot water dispersibility is no longer comprehensively ensured. This results in an insufficient distribution in the rinsing liquor and a reduced absorption capacity of the quaternary ammonium compound on the fiber fibers.

Object of the invention ·

The object and the object of the invention consisted of formulating warm and cold water-soluble or "dispersible" fabric softener concentrates by combination of known active and dispersing aids with special quaternary ammonium compounds containing ester groups, which are present both directly in the

Presentation of the essence of the invention

It has now been found that it is possible to prepare dispersion-stable, hot and cold water-dilutable fabric softener concentrates with uniform distribution and wind-up properties on textiles and the same softening and antistatic effect as those based on distearyldimethylammonium chloride or quaternary imidazolinium salts, if the following active ingredients are homogeneous at 70 to 90 ^° C. formulated:

For visual enhancement, a soluble dye may be added to the dispersion. If necessary, it is perfumed at room temperature.

The softener concentrates produced in this way are highly dispersion-stable. They have a water deficit of about 66 % compared to commercially available products. In small packages of 340 g content, they can be used as Uachfüllgut for original bottles of fabric softener. By transferring the contents of the small package into a 1 liter original bottle, the user can, after filling with water, independently prepare a softener dispersion corresponding to the usual application concentrations.

Of crucial importance for the qualitative assessment of a fabric softener are its softening and antistatic effects. Comparing approximately equal concentrations of a formulation based on distearyldimethylammonium chloride - the most commonly used anti-corrosive agent - with a formulation of the present invention shows that the latter is equivalent to the former. This must undoubtedly be regarded as surprising since the effect occurs only with the combination of active substances described.

Example of use

To evaluate a fabric softener concentrate according to the invention which exhibits softening and antistatic effects on cotton and synthetic fiber fabrics, the following solubilizers, emulsifiers and quaternary ammonium compounds were homogenized with water at 85.degree.

After the dispersion had cooled, 0.9 kg of perfume oil were stirred into the formulation at room temperature. The fabric softener concentrate thus obtained was sealed and stored in pouches of triple composite polyethylene / aluminum / polyester with a filling compound of 340 g.

For comparative quality testing, the contents of a bag were diluted with water to 1 liter. This softener formulation is for comparative utility testing with an aqueous dispersion of 11 % distearyldimethylammonium chloride. As the following results show, the combination according to the invention has an analogous utility value to the dispersion of distearyldimethylammonium chloride used, despite the lower percentage of quaternary ammonium compounds added in the summation.
