Abstract (en)
[origin: WO9813462A1] Aqueous liquid detergent compositions are described which comprise a proteolytic enzyme wherein the proteolytic activity is reversibly inhibited by a peptide aldehyde and a source of boric acid. In a particularly preferred embodiment, liquid detergent compositions are disclosed which contain a detersive surfactant, a proteolytic enzyme, a peptide aldehyde, boric acid, and diol ions. The combination of peptide aldehyde and boric acid act to provide improved stability of protease and other enzymes.
