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.
Claims9
A composition of matter useful as a surfactant in finished formulations for cleaning dishes, hard surfaces, and laundry, comprising an anionic form of a material described by the formula:
- in which R1 is a hydrocarbyl group containing between 5 and 19 carbon atoms, saturated or unsaturated, straight-chain, branched, or cyclic;
- R2 and R3 may each independently be a hydrogen, or a hydrocarbyl group selected from the group consisting of:
- methyl and ethyl;
- x may be any integer between 7 and 20, including 7 and 20;
- R4 and R5 may each independently be a hydrogen, or a hydrocarbyl group selected from the group consisting of:
- methyl and ethyl;
- and y is independently equal to zero or 1.
