Problems solved by technology

[0004] Automatic dishwashing compositions can be designed to perform optimally under certain conditions of use, for example, a composition can be designed to perform optimally in a soft water cycle, however, a composition that performs optimally in soft water will cycle in hard water. May not have optimal performance in the water cycle and vice versa

Embodiment

[0230] Egg yolk removal by automatic dishwashing compositions comprising the variant protease was compared to using the same composition comprising the parent protease.

[0231] The compositions shown in Table 1 were used. 3 g of each composition was dissolved in one liter of deionized water to produce a pH 11 cleaning solution. The corresponding proteases are added to the cleaning solution at levels between 0.25-0.75 ppm.

Abstract

A phosphate-free automatic dishwashing cleaning composition comprising: a)a protease wherein the protease is a variant having at least 60% identity with the amino acid sequence of SEQ ID NO:1 or SEQ ID NO:2 comprising two negatively charged amino acid residues, aspartic acid (D) and / or glutamic acid (E), in positions 124-131 using the SEQ ID NO: 1 numbering and the SEQ ID NO:2, respectively; and b) from 10 to 50% by weight of the composition of a complexing agent system comprising from 0 to less than 30% by weight of the composition of citric acid.

Description

technical field [0001] The invention belongs to the field of detergents. In particular, the present invention relates to phosphate-free automatic dishwashing detergent compositions comprising proteases. The composition provides improved cleaning of burnt sugary food soils even under stressful conditions. Background technique [0002] Some soils, such as burnt sugary food soils, are difficult to remove from dishes during automatic dishwashing. Proteinaceous soils such as eggs are also difficult to remove. [0003] Due to environmental concerns, phosphates are increasingly being replaced by biodegradable complexing agents. These complexing agents can have a strong binding capacity for metals and / or are used at high levels and can adversely affect enzyme performance, specifically, complexing agents can negatively affect proteases by extracting their structural calcium metal ions Influence. Proteases can be affected in product and / or use. Under fully built or overbuilt con...
