Highly alkaline textile washing agent comprising protease

Abstract

The present disclosure relates to a textile washing agent having at least one protease and a washing agent ingredient for cleaning textiles by removing protease-sensitive stains. The protease may have proteolytic activity and include an amino acid sequence having at least 70% sequence identity with the amino acid sequence given in SEQ ID NO:1 over its entire length and, in each case based on the numbering according to SEQ ID NO:1. The protease may have amino acid substitutions at the positions corresponding to positions 9, 130, 133, 144, 217, 252 and 271; and at least one additional amino acid substitution at least one of the positions corresponding to positions 6, 89, 131, 166, 189, 211 or 224. The washing agent may have a pH ranging from approximately 9 to approximately 12, measured in a 1 wt. % solution in deionized water at 20° C.
