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
water 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.
