Heavy duty liquid detergent compositions containing enzymes stabilized by quaternary nitrogen substituted proteins

摘要

This invention provides a liquid detergent composition comprising: (a) 5-85% by weight of a surfactant selected from the group consisting of anionic, nonionic, cationic, ampholytic or zwitterionic surfactants and mixtures thereof; (b) an effective amount of enzyme; and (c) an amount of protein containing quaternary nitrogen substituent sufficient to stabilize the enzyme from loss of activity.
