IT IS DISCLOSED THAT CERTAIN MIXTURES OF ALKYL SULFATE AND ALKYL ALKOXY SULFATE DETERGENTS HAVE SUPERIOR PROPERITIES WHEN USED IN HARD WATER WHERE THE ALKYL GROUPS OF THE SULFATES RANGE FROM ABOUT 10 TO ABOUT 20 CARBON ATOMS AND WHEREIN FROM ABOUT 10 TO ABOUT 50 PERCENT OF THE ALKYL GROUPS ARE DECYL. IT IS DISCLOSED THAT SUCH SULFATES ARE USEFUL PER SE AND IN FORMULATIONS WITH OTHER ADJUVANTS WITH OR WITHOUT OTHER DETEGENT ACTIVE MATERIALS SUCH AS TERTIARY AMINE OXIDES, ALKYL BENZENE SULFONANTES, LINEAR ALKYL BENZENE SULFONATES, FATTY ACID ETHANOL AMIDES, AND FATTY ACID DIETHANOL AMIDES. |
