"For use in bactericidal textile treatment agents suitable brightener combination "

As is known, easy care fabrics from equipped cellulose fibers, synthetic and parsers are blends of cellulosic and synthetic fibers may not be treated at temperatures above 80 ⁰ C. In order to achieve a complete destruction of all germs on the textile material even at low treatment temperatures, bactericidal substances are usually added to the agents, such as washing agents, rinsing agents or stiffening agents. It has been shown, however, that the whiteness of optically brightened textiles is often reduced considerably. The object was therefore to find such combinations of optical brighteners and bactericides
To develop substances that do not show these undesirable properties.

The invention relates to a combination of optical brighteners and bactericides suitable for treating textiles Compounds characterized by a content of
