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.
