Alkoxylated hydroxyamide detergents
Abstract
Abstract A NOVEL CLASS OF BIODEGRADABLE DETERGENTS HAVING IMPROVED DISPERSION PROPERTIES IN HARD WATER ARE THE WATERSOLUBLE REACTION PRODUCTS OBTAINED BY REACTING A LACTONE WITH AN ALKANOLAMINE WITH AN ALLKYLENE OXIDE. MAINTAINHYDROXYALKANOLAMIDE WITH AN ALKYLENE OXIDE. MAINTAINING A PREFERRED RATIO OF THE NUMBER OF MOLES OF ALLKYLENE OXIDE REACTED WITH THE INTERMEDIATE AMIDE PRODUCT TO THE TOTAL NUMBER OF CARBON ATOMS IN THE LACTONE PRECURSOR WITHIN A SPECIFIC RANGE HAS BEEN FOUND TO PROVIDE PRODUCTS HAVING OPTIMUM DETERGENCY PROPERTIES. AMIDE PRODUCTS HAVING FROM 8 TO 30 CARBON ATOMS IN THE ACID PORTION AND CONTAINIING FROM ABOUT 1.5 TO ABOUT 20 TOTAL ETHYLENE OXIDE UNITS ARE MOST PREFERRED.
