Bleach activator cogranulates of one or more ammonium nitrites and at least one further bleach activator obtained by spraying an aqueous solution of one or more ammonium nitrites onto the further bleach activator, granulating the resulting mixture and drying and sieving the moist granulate.

Process for preparing bleach activator cogranulates

Granular secondary alkanesulfonate, essentially comprising finely divided, solid sec. alkanesulfonate and an additive. This granular sec. alkanesulfonate is obtained by grinding and mixing coarse sec. alkanesulfonate with an additive. The resulting alkanesulfonate can be used in solid detergent and cleaning product compositions or directly for producing extrudates, pressed articles or compacts.

Granular secondary alkanesulfonate

A pulverulant, dry bleach activator, in particular tetraacetylethylenediamine is first moistened with water and then mixed with a dry auxiliary, in particular, with Na carboxymethylcellulose. This mixture is then granulated.
