Abstract:
A process for the production of a detergent composition containing a water soluble organic, anionic, nonionic, zwitterionic or amphoteric detergent active compound, or a mixture of such compounds and a detergency builder salt; characterized by the steps that consist of mixing the detergent active compound with water, obtaining an aqueous liquid detergent that is then heated and a reinforcing salt is added, of the detergency, preferably a sodium salt, in a weight ratio of detergent active compound to the detergency builder salt from about 1:20 to about 50: 1, preferably from about 3: 1 to about 1:10, and then optionally, evaporating at elevated temperatures at least part of the water to obtain a detergent composition in powder, the general formula of the detergent-reinforcing salt being: **(See formula)** where R1 is a hydrogen atom, an alkyl group of 1 to 12 carbon atoms, a hydroxyalkyl group of 1 to 4 carbon atoms, a caboxyl group (-COOM) or a phenyl group; n is 0o1; when n is 1, R2 and R3 are the same or different and represent hydrogen atoms, methyl groups, or carboxymethyl groups (-CH2COOM); when n is 0, there is a double bond between the carbon atoms C'and C "; X is a carboxyl group (-COOM), a sulfate group (-OSO3M) or a sulfonate group (-SO3M); a is 0, 1o2; b is 0o1; Z is a bivalent linking group -0-, -S-, -NH-o-NR4- where R4 is an alkyl group or a hydroxyalkyl group of 1 to 4 carbon atoms or a carboxymethyl group (-CH2COOM), with the proviso that when Z is -0-, a must be 0, X must be a carboxyl group (-COOM), and R1 cannot be a hydrogen atom when R2 and R3 are hydrogen atoms and b is 0; and M is an alkali metal, ammonium, or substituted ammonium cation.
