Abstract

The present invention relates to laundry detergent compositions containing particles bleacher, which contains a fungal cellulase without the cellulose binding structure domain and having a best pH between 4-10, and a hydrophobic bleach activator, thus providing improved overall washing, outstanding washing to all kinds of stains / dirt, and improved whiteness performance results.

Description

technical field [0001] The present invention relates to granular bleach-containing laundry detergent compositions comprising specific cellulase enzymes and a hydrophobic bleach activator. Background of the invention [0002] Detergent compositions now include a complex combination of active ingredients for some specific needs: surfactant systems, enzymes to provide cleaning and fabric care benefits, bleaches, builder systems, suds suppressors, soil suspending agents, Detergents, optical brighteners, softeners, dispersants, dye transfer inhibiting compounds, abrasives, bactericides, fragrances, the overall performance of them has indeed improved in recent years. Current detergent formulations often include detergent enzymes and more specifically cellulases among others. [0003] Cellulase activity refers to where cellulose fibers or substrates are hydrolyzed by a cellulase, and depending on the specific function of the cellulase, it can be an endo- or e...
