Problems solved by technology

In addition, it has been surprisingly found that this raw starch remaining on the surface further traps the soil, which when present on the fabric surface results in a dirty appearance to the surface being cleaned

Abstract

The present invention relates to detergent compositions, including laundry, dishwashing and / or hard surface cleaner compositions, comprising a raw starch degrading enzyme characterized in that its activity in degrading corn raw starch (Ra) is comparable to degrading gelatinized corn starch (Ga) The activity ratio: [Ra / Ga] is greater than 0.2, preferably greater than 0.35. This composition provides excellent removal of starchy stains and soils and, when formulated as a laundry composition, provides excellent whiteness maintenance and soil cleaning.

Description

field of invention [0001] The present invention relates to detergent compositions comprising raw starch degrading enzymes. Background of the invention [0002] The performance of a detergent product is determined by a variety of factors, including the ability to remove soil. Accordingly, detergent ingredients such as surfactants, bleaches and enzymes have been incorporated into detergents. A specific example of this is the use of proteases, lipases, amylases and / or cellulases. [0003] Proteases are enzymes commonly used in cleaning applications. Proteases are known to have the ability to hydrolyze other proteins. This ability has been exploited by incorporating naturally occurring or genetically engineered proteases in laundry detergent compositions. It is known to incorporate lipolytic enzymes in detergent compositions to improve cleaning performance, eg enhanced removal of triglyceride containing soils and stains from fabrics. The activity of cellulase is an activity...
