Abstract
New enzyme granulates are described which contain an organic disulfide compound (R—S—S—R), particularly they contain the free amino acid cystine, optionally mixed with the amino acid cysteine. The new enzyme granulates are for us in detergent and cleanser compositions, particularly in dishwasher compositions, and they have properties. For example, insofar as protecting objects made of silver against tarnishing, for example, dishes, cutlery, and other objects to be cleaned.
Claims25
An enzyme granulate comprising, a core having a composition of, (i) 0.8-20 wt % enzyme protein content, (ii) 40-90 wt % water-soluble fillers, water-insoluble fillers or mixtures thereof, (iii) 5-15 wt % of one or more binders, (iv) 0.2-5 wt % of one or more humectants, and (v) 3-20 wt % of an organic disulfide compound, with respect to the enzyme granulate as 100 wt %.
An enzyme granulate comprising, a core having a composition of, (i) one or more enzymes, (ii) a water-soluble filler, water-insoluble filler or mixtures thereof, and (iii) an organic disulfide compound of the formula R1—S—S—R2 wherein R1 and R2 are alkyl or alkyl substituted with amino, metal, carboxy, or hydroxy groups or mixtures thereof, and wherein R1 and R2 may be identical, different or combined with the disulfide group S—S to form a ring.
An enzyme granulate comprising, a core having a composition of, (i) 0.8-20 wt % enzyme protein content, (ii) 40-90 wt % water-soluble filler, water-insoluble filler or mixtures thereof, (iii) 5-15 wt % of one or more binders, (iv) 0.2-5 wt % of one or more humectants, and (v) 3-20 wt % of an organic disulfide compound with respect to the enzyme granulate as 100 wt %, and wherein said disulfide compound is in the form of the free amino acid cystine or in the form of a cystine/cysteine mixture.
