Abstract
There is provided a detergent composition comprising conventional detergent components characterized in that it contains a lactase enzyme. The lactase enzyme is preferably incorporated into the compositions at a level of from 0,0001% to 2% active enzyme by weight of the composition.
Claims13
A detergent composition comprising:
- a) from 0.1% to 60% by weight, of a detersive surfactant;
- b) from 1% to 80% by weight, of a builder;
- c) from 0.0001% to 2% by weight, of a lactase enzyme selected from the group consisting of lactase enzymes ex Aspergillus niger, Aspergillus Oryzae, Saccharomyces lactis, Kluyveromyces fragilis groups, and mixtures thereof;
- and
- d) the balance carriers and adjunct ingredients, said adjunct ingredients selected from the group consisting of enzymes, enzyme stabilizers, dye transfer inhibitors, corrosion inhibitors, heavy metal ion sequestrants, softening agents, hydrotropes, filler salts, perfumes, colorants, and mixtures thereof.
