Abstract
In a liquid detergent comprising a subtilisin and optionally a second (non-subtilisin) enzyme, the combination of a peptide aldehyde (or hydrosulfite adduct thereof) with a salt of a monovalent cation and a monovalent organic anion has a synergistic stabilizing effect on the subtilisin and/or the second enzyme. The improved enzyme stability is of particular interest in liquid detergent compositions where the enzyme would otherwise have poor storage stability.
Claims15
A boron-free liquid detergent composition, comprising
- a) a linear alkyl benzene sulfonate, (LAS)
- b) a subtilisin,
- c) a subtilisin inhibitor which is a peptide aldehyde or a hydrosulfite adduct thereof,
- d) a salt of a monovalent cation and a monovalent organic anion of 1-6 carbons, and
- e) at least 10% water;
- which has a total content of linear alkyl benzene sulfonate and branched alkyl benzene sulfonate (LAS and BABS) and alkyl sulfate (AS) which is larger than the total content of alkyl ethoxy ether sulfate (AES) and methyl ester sulfonate (MES).
