Abstract
Provided herein are sulfosuccinamates made using polyetheramines as intermediates. The sulfosuccinamates according to the invention exhibit excellent detergency when employed in formulations used as hard surface cleaners, laundry detergents, and dishwashing liquids. In addition, the sulfosuccinamates according to the invention have an unexpectedly high degree of water hardness tolerance, and are easier to produce than similar materials found in the prior art owing to the fact that the product and its intermediates exist in liquid form.
