Storage-Stable Liquid Detergent or Cleaning Agent Containing Protease and Lipase

A method of formulating a liquid washing or cleaning agent for storage stability of cellulolytic activity, the method comprising:

• (1) mixing, to formulate the liquid washing or cleaning agent:
• (a) a protease comprising the amino acid sequence of SEQ ID NO:
• 2, wherein said amino acid sequence imparts a proteolytic activity to the protease, and wherein the protease imparts a proteolytic activity to the washing or cleaning agent;
• and
• (b) a cellulase;
• and
• (2) storing the liquid washing or cleaning agent for at least 4 weeks, wherein the liquid washing or cleaning agent exhibits increased storage stability of cellulolytic activity after storage as compared to a control liquid washing or cleaning agent that is the same liquid washing or cleaning agent but comprises a protease that differs from the protease of (1)(a) solely by having a protease comprising the amino acid arginine (R) at location 99 in the count according to SEQ ID NO:
• 1;
• wherein the liquid washing or cleaning agent exhibits increased storage stability of cellulolytic activity after storage for 4 weeks at 30° C. as compared to a control liquid washing or cleaning agent that is the same liquid washing or cleaning agent but comprises a protease that differs from the protease of (1)(a) solely by having a protease comprising the amino acid arginine (R) at location 99 in the count according to SEQ ID NO:
• 1, wherein, at the beginning of such storage, the liquid washing or cleaning agent and the control liquid washing or cleaning agent have the same concentration of protease and the same concentration of cellulase, and
• wherein the protease and the cellulase are in solution in the liquid washing or cleaning agent.
