Mixtures of different surface-active ammonium compounds can also be used. The agents according to the invention preferably contain quaternary ammonium salts according to formula 1, in which the radicals R 'and R _{2 represent} straight-chain, saturated hydrocarbon radicals with β to 18 carbon atoms and the radicals R and R _{2 represent} methyl or ethyl groups,

vary. In agents which are said to have particularly good whitening power, the weight ratio of optical brightener to surface-active ammonium compound can be from 5:95 to 25 * 75. In those agents which primarily have a good softening effect, the ratio is 5 '· 95 to 0.5: 99> 5 · Agents are preferably used in which the specified weight ratio is between 10:90 and 1 : 99 lies.

The mixtures of surface-active ammonium compounds and optical brighteners can be mixed in anhydrous form or in the presence of water or water-miscible solvents. In the first case, mixtures are obtained with a solid to lard-like consistency, which, if necessary, can be solidified or converted into granular, pourable powders by adding inert fillers. However, the mixtures are preferably in the form of water-containing, pourable dispersions or pastes. Such dispersions generally contain > to 15, preferably 5 to 10 wt .- ^ of surface-active ammonium compound.

The storage stability of the aqueous dispersions can, if necessary, be improved by adding small amounts of stabilizers. Suitable stabilizers are, for example, fatty acid alkylolamides, in particular fatty acid mono- or diethanolamide,

example

The following example used a quaternary ammonium salt of the formula

R ₁ R ₂ N (CH ₅ ),

Cl

in which the radicals R ₁ and Rp are straight-chain, saturated alkyl radicals

represent having 16 to 18 carbon atoms. The optical brightener was ύ used in the form of the sodium salt.

A dispersion of the following composition was prepared:

8.0 % quaternary ammonium salt

0.2 fo optical brightener

2.7 % isopropanol

0.5 % polyethylene glycol (molecular weight 400)

0.3 fo sodium acetate. .

0.1 pounds of perfume

Remainder of distilled water

The dispersions were in tap water from ΐβ dH to one Diluted ammonium salt content of 0.3 g / l. With these solutions textiles washed in a household washing machine with a commercial heavy duty detergent at a liquor ratio treated by 1: 6. Then it was spun and dried. The textiles had a soft, pleasant handle and were characterized by a high degree of whiteness.

For comparison, textiles were made in the same version with a Treats means that

a) no brightener

b) contained the same amounts of optical brighteners in which, deviating from the above formula, those on the two triazine residues NHp groups located in one case by anilino residues, in the second case had been replaced by morpholino residues. The textiles made with the brightener-free Agents or agents containing the two last-mentioned brighteners had been treated, showed in comparison compared to the textiles treated with the agent according to the invention, a significantly lower degree of whiteness.
