Abstract
Described herein are cleaning compositions comprising a mannanase. In addition, described herein are methods of making the cleaning compositions and using the cleaning compositions for having an improved storage stability.
Claims20
A liquid cleaning composition comprising
- a) a surfactant composition wherein the weight ratio of the total amount of all non-ionic surfactants (NIO) to the total amount of all surfactants in the cleaning composition is equal or below 0.88 times the weight ratio of the total amount of all alkyl benzene sulfonates (AS) to the total amount of all surfactants in the cleaning composition minus 0.1, wherein the weight ratio of the total amount of all AS to the total amount of all surfactants in the cleaning composition is greater 0.1136, and
- b) a mannanase variant comprising
- b1) one or more amino acid substitutions at positions selected from the group consisting of 59, 66, 89, 234, 259, 282, 318, 319, and 322, according to the numbering of SEQ ID NO:
- 11, and an amino acid sequence which is at least 70%, but less than 100% identical to SEQ ID NO:
- 11, or
- b2) one or more amino acid substitutions at positions selected from the group consisting of 59, 66, 89, 234, 259, and 282, according to the numbering of SEQ ID NO:
- 11, and an amino acid sequence which is at least 70%, but less than 100% identical to amino acids 1-296 of SEQ ID NO:
- 11.

A method for providing a cleaning composition with improved storage stability and/or wash performance, comprising the steps of mixing
- a) a surfactant composition wherein the weight ratio of the total amount of all non-ionic surfactants (NIO) to the total amount of all surfactants in the cleaning composition is equal or below 0.88 times the weight ratio of the total amount of all alkyl benzene sulfonates (AS) to the total amount of all surfactants in the cleaning composition minus 0.1, wherein the weight ratio of the total amount of all AS to the total amount of all surfactants in the cleaning composition is greater 0.1136, and
- b) a mannanase variant comprising
- b1) one or more amino acid substitutions at positions selected from the group consisting of 59, 66, 89, 234, 259, 282, 318, 319, and 322, according to the numbering of SEQ ID NO:
- 11, and an amino acid sequence which is at least 70%, but less than 100% identical to SEQ ID NO:
- 11, or
- b2) one or more amino acid substitutions at positions selected from the group consisting of 59, 66, 89, 234, 259, and 282, according to the numbering of SEQ ID NO:
- 11, and an amino acid sequence which is at least 70%, but less than 100% identical to amino acids 1-296 of SEQ ID NO:
- 11.
