- the bleaching agent of the type mentioned places high demands on the consumer: it must be compatible with textiles, i.e. treatment with the aggressive chemical hypochlorite means that the stains must be removed without attacking the tissue. Since skin contact with the bleaching agents is not excluded, the preparations must also be as dermatologically compatible as possible. Another problem is that hypochlorite solutions also attack metals and the dissolved metal traces can be deposited on the textile fibers during washing, which is ultimately reflected in the yellowing of the fabric. Market means are trying to prevent this redeposition by using silicates, but in practice this measure does not always prove to be satisfactory.
- the complex object of the invention was to provide aqueous bleaching agents which are simultaneously chlorine-stable, gentle on textiles and as kind to the skin as possible, have a sufficiently high viscosity and reliably prevent the deposition of metal traces on the fabric with a high stain removal capacity.
