Abstract
Liquid detergent containing enzymes particularly proteases are stabilized against enzyme degradation prior to use by inclusion of an inhibitor of the enzyme which binds to the enzyme such that prior to use of the detergent at least about 90% of the enzyme is bound to the enzyme inhibitor essentially at the enzyme active site. Such enzyme inhibitor so selected can be used effectively in concentrations much lower than previously taught.
Claims10
A liquid detergent composition comprising:
- a) from about 1% to about 75% of a surfactant;
- b) from about 10% to about 95% of water by weight;
- c) from about 0.01% to about 5% of an enzyme suitable for use in detergent compositions;
- and
- d) an enzyme inhibiting amount of turkey ovomucoid such that prior to use of the detergent, the turkey ovomucoid binds at least about 90% of the enzyme and the remaining enzyme is in its free form, and wherein upon appropriate dilution of the composition at least about 25% of such bound enzyme is released in its free form.
