Problems solved by technology

This is problematic with both colored and white fabrics, but may be particularly noticeable on white or light colored fabrics, such as around linings and cuffs where incomplete cleaning occurs
Since it can cause a bad smell, this could also be the problem

Embodiment 1-7

[0240] Example 1-7 Heavy Duty Liquid Laundry Detergent Composition

[0241]

[0242]

[0243] Based on total cleaning and / or treatment composition weight. Enzyme content is reported as raw material.

Embodiment 8 to 16

[0244] Examples 8 to 16 unit dose composition

[0245] These examples provide various formulations for unit dose laundry detergents. Compositions 8 to 12 comprise a single unit dose compartment. This film is used to encapsulate the composition in PVA.

[0246]

[0247]

[0248] Based on total cleaning and / or treatment composition weight. Enzyme content is reported as raw material.

[0249] In the following examples, the unit dose has three compartments, but similar compositions can be prepared with two, four or five compartments. The membrane used to encapsulate the compartment is polyvinyl alcohol.

[0250]

[0251]

[0252]

[0253] Enzyme levels are reported as raw materials based on total cleaning and / or treatment composition weight.

Embodiment 19 to 24

[0254] Examples 19 to 24 : A granular laundry detergent composition for hand washing or washing machines, typically top loading machines.

Abstract

A cleaning composition comprising a nuclease enzyme, preferably a deoxyribonuclease and / or ribonuclease enzyme and a surfactant system comprising an anionic surfactant and a nonionic surfactant wherein the weight ratio of anionic to non-ionic surfactant is from 1.5:1 to 1:10.

Description

technical field [0001] The present invention relates to cleaning compositions comprising nucleases. Background technique [0002] Fabric whitening is a constant challenge for laundry detergent manufacturers. The specific problem may be the accumulation of dirt over time. This is problematic with both colored and white fabrics, but can be especially noticeable on white or light colored fabrics, such as around linings and cuffs where incomplete cleaning occurs. Since it can cause a bad smell, that could also be the problem. Laundry detergent manufacturers can consider many options based on the different cleaning technologies available such as surfactants, bleaches and enzymes. Many different types of enzymes are available to detergent formulators for cleaning different types of soils such as lipase, protease, amylase, cellulase, peroxidase, aryl esterase, cutinase, pectinase, mannan carbohydrases and deoxyribonucleases. DNase may be particularly effective in cleaning this...
