A washing or cleaning agent may include at least one amylase and at least one protease with an amino acid sequence having at least 70% sequence identity to the amino acid sequence specified in SEQ ID NO:1 over the entire length thereof and has an amino acid substitution at at least one of the positions corresponding to the positions 12, 43, 122, 127, 154, 156, 160, 211, 212, or 222, in each case based on the numbering according to SEQ ID NO:1. Corresponding cleaning methods and uses of such a washing or cleaning agent for cleaning textiles and/or hard surfaces are also disclosed.

Washing and cleaning agents comprising protease and amylase

The object of the present invention is to provide a detergent, especially a dishwashing detergent, with improved detergency. Detergent compositions having metal complexes with certain salicylidene ligands, which may be created in situ, solve this problem.

Dishwashing detergents containing a salicylidene-based chelant

An automatic dishwashing agent includes builder(s), enzyme(s) and a) a nonionic surfactant A of the general formula RO(AlkO)M(OAlk)OR, in which Rand Rmutually independently denote a branched or unbranched, saturated or unsaturated, optionally hydroxylated alkyl residue with 4 to 22 carbon atoms; Alk denotes a branched or unbranched alkyl residue with 2 to 4 carbon atoms; x and y mutually independently denote values between 1 and 70; and M denotes an alkyl residue from the group CH, CHR, CRR, CHCHRand CHRCHR, with Rand Rmutually independently denoting a branched or unbranched, saturated or unsaturated alkyl residue with 1 to 18 carbon atoms; b) a nonionic surfactant B which differs from the nonionic surfactant A; and c) an anionic copolymer C. The agent imparts an improved drying and rinsing result.
