Abstract

The present invention relates to detergent compositions, including laundry, dishwashing, and/or hard surface cleaner compositions, comprising a maltogenic alpha-amylase enzyme and a detergent ingredient selected from the group consisting of a nonionic surfactant, a protease, a bleaching agent and/or mixtures thereof. Such compositions provide excellent removal of starch-containing stains and soils, and when formulated as laundry compositions, excellent whiteness maintenance and dingy cleaning.

Description

field of invention [0001] The present invention relates to detergent compositions comprising maltose alpha-amylase and detergent ingredients selected from nonionic surfactants, proteases and / or bleaching agents. Background of the invention [0002] The performance of a detergent product is determined by many factors, including the ability to remove soil. Thus, detergent ingredients such as surfactants, bleaches and enzymes have been incorporated into detergents, one specific example of which is the use of proteases, lipases, amylases and / or cellulases. [0003] In particular, amylases have long been recognized in detergent compositions to remove starchy food residues or starch films from dishware or hard surfaces or to provide protection against starchy soils and in laundry and dishwashing applications in general. Cleaning performance on other soils encountered. In fact, starchy substances such as amylose and amylopectin are the major constituents of soils / stains encounter...
