Enzyme-containing detergent compositions for neutral washing
Abstract
Abstract ENZYME-CONTAINING DETERGENT COMPOSITIONS ESPECIALLY ADAPTED TO LAUNDRY APPLICATIONS UNDER NEUTRAL AND NEARNEUTRAL CONDITIONS OF PH ARE DISCLOSED. THE DETERGENT COMPOSITIONS CONSIST ESSENTIALLY OF A SYNTHETIC ORGANIC DETERGENT CHARACTERIZED BY SOLUBILITY IN WATER OF AT LEAST 0.05% AT A TEMPERATURE OF ABOUT 80*F. TO ABOUT 130* F. EFFICIENT SOIL-REMOVING AND SOIL-DISPERSING PROPERTIES IN WATER IN AN AMOUNT OF ABOUT 0.05% AND RESISTANCE TO PRECIPITATION BY HARD WATER MINERAL IONS; 0.001% TO 5% OF A PROTEOLYTIC ENZYME CHARACTERIZED BY PROTEOLYTIC ACTIVITY UP TO ABOUT 130*F. IN THE PH RANGE OF 6 TO 8.5; AND A PHOSPHORUS-CONTAINING COMPOUND HAVING SUFFICIENT CALCIUM SEQUESTRATION PROPERTIES TO REDUCE THE CALCIUM ION CONCENTRATION OF AN AQUEOUS SOLUTION CONTAINING 1.2X10**-3 M OF CALCIUM ION TO A CONCENTRATION OF 1.7X10**-4 M OR LESS WHEN EMPLOYED IN AN AMOUNT OF UP TO 0.1% OF THE SOLUTION. THE COMPOSITIONS OF THE INVENTION HAVE A PH OF FROM 6 TO 8.5 IN AQUEOUS SOLUTION AT A CONCENTRATION OF 0.12%.
