Description

Field of the Invention

The invention is in the field of bleaching and disinfecting agents and relates to active chlorine preparations containing fragrances in a microencapsulation.

State of the art

Cold washing continues to dominate in the Mediterranean countries, but also in the United States of textiles. As a result, conventional bleaches, such as. B. perborates or percarbonates are hardly used since they do not have any particular activity at temperatures around 20 ° C unfold. Liquid wash bleaches are therefore usually added to the wash liquor are usually surfactant preparations containing up to 10% by weight hypochlorite acts; Comparable agents are also used for cleaning and disinfecting hard surfaces set. The hypochlorite bleaches have an unpleasant sting even when diluted heavily the smell of chlorine, which is why fragrances are added to them. An overview of hypochlorite lyes can be found for example from J. Josa and M. Osset in Jorn. Com. Esp. Deterg. 27, 213 (1997).

In this context, reference should also be made to the European patent application EP 0397246 A1 sen, from the perfume capsules of an average size of less than 350 microns, preferably not more than 150 µm, with a water-insoluble brittle casing and cleaning or washing are known with these perfume capsules.

Now, a sufficiently large number of perfume oils are known from the prior art, the are also hypochlorite-stable over a long period of time and are not oxidized, include substances with citrus aroma but not to. After that consumer smell just with freshness and cleanliness is associated, there is a desire in the market to offer hypochlorite bleach with a citrus scent that despite the known chemical instability of the fragrances is sufficiently stable, d. H. no later than result in the desired fresh fragrance when used. The object of the invention is therefore in it  passed a simple technical solution for the described problem put.

Description of the invention

The invention relates to active chlorine-containing preparations with a fragrance content, which che are characterized in that the fragrances are in microencapsulated form.

Surprisingly, it was found that bleaching agents and disinfectants containing active chlorine then Have fragrances stably formulated if you use them in microencapsulated form. The micro Capsules are chemically and physically, in particular spatially, in the agents according to the invention, stable, d. H. on average neither decomposition nor settling of the microcapsules occurs. To this Bleach and disinfectants can be produced using a practically free selection of fragrances provide, in particular now also storage-stable preparations with citrus aroma accessible are.

Alkali hypochlorites and alkali hydroxides
