Abstract
The subject invention relates to a novel class of compounds, known as alkali metal salts of hydroxyalkyl sulfonates of aminoalkyl alkanol amines and/or aminoalkyl alkanol ethers, the methods of making such compounds, the alkali-stable solutions containing such compounds, and the use of said solutions as strong detergent compositions. Those alkali-stable solutions are temperature-stable, exhibit superior wetting characteristics, and can be made into low or high foam formulations useful for hard surface cleaning, oven and grill cleaning, metal cleaning, bottle washing, steam cleaning and wax stripping formulations.
