ABSTRACT:
The present invention relates to a liquid enzyme cleaning composition in which the enzyme is stable at alkaline pH and: at high concentration of boric acid salt; in the absence of sodium ion; and/or in the presence of at least about 40 wt-% water. In an embodiment, water is present at concentrations of at least about 60 weight percent. The present enzyme cleaning composition typically yields superior soil (especially protein soil) removal properties. In an embodiment, the composition of the invention stabilizes the enzyme with potassium and/or alkanolamine borate.
