Aqueous liquid detergent compositions are described which comprise a proteolytic enzyme wherein the proteolytic activity is reversibly inhibited by a peptide aldehyde and calcium. More specifically, liquid detergent compositions are disclosed which contain a detersive surfactant, a proteolytic enzyme, a peptide aldehyde, and calcium ions. The combination of peptide aldehyde and calcium ions acts to provide synergistic protease inhibitor benefits.
L'invention a pour objet des compositions de détergents liquides aqueux, qui contiennent un enzyme protéolytique. L'activité protéolytique est inhibée de manière réversible par un aldéhyde peptidique et du calcium. L'invention concerne plus spécifiquement des compositions de détergents liquides qui contiennent un tensioactif détergent, un enzyme protéolytique, un aldéhyde peptidique et des ions calcium. La combinaison d'aldéhyde peptidique et d'ions calcium procure les avantages synergiques de l'inhibiteur de protéase.
