Abstract: An aminocarboxylic acid is produced from a solution that includes an aminocarboxylate and a solvent. A method of producing the aminocarboxylic acid comprises the step of combining a sulfonic acid and the solution comprising the aminocarboxylate and the solvent to produce a composition. An example of the aminocarboxylate is a salt of methylglycine diacetic acid (MGDA). An example of the sulfonic acid is methane sulfonic acid (MSA). The composition comprises the aminocarboxylic acid. The method further comprises the step of isolating the aminocarboxylic acid from the composition.

Abstract: An aminocarboxylic acid is produced from a solution that includes an aminocarboxylate and a solvent. A method of producing the aminocarboxylic acid comprises the step of combining a sulfonic acid and the solution comprising the amino-arboxylate and the solvent to produce a composition. An example of the aminocarboxylate is a salt of methylglycine diacetic acid (MGDA). An example of the sulfonic acid is methane sulfonic acid (MSA). The composition comprises the aminocarboxylic acid. The method further comprises the step of isolating the aminocarboxylic acid from the composition.

Abstract: A builder composition includes a chelating component A), a builder component B), a polymeric component C), and optionally an alkali component D) and/or a phosphorous-containing component E). The chelating component A) includes a1) methylglycine-N-N-diacetic acid (MGDA) and/or an alkali salt thereof, and/or a2) N,N-bis(carboxymethyl)-L-glutamate (GLDA) and/or an alkali salt thereof, and/or a3) ethylenediaminetetraacetic acid (EDTA) and/or an alkali salt thereof. The builder component B) includes b1) a metal silicate, and/or b2) a metal carbonate, and/or b3) a metal citrate. The polymeric component C) includes c1) an acrylic-maleic copolymer, and/or c2) polyacrylic acid (PAA).

Abstract: A detergent composition comprises a chelating component, a metal citrate, and a metal carbonate. At least one of following two conditions is typically true: X=(2.29*a1)+(2.51*a2)+(2.26*b)+(2.75*c)+(?0.15*a1*b)+(0.26*a2*b)+(1.33*a2*c); and/or Y=(4.00*a1)+(3.76*a2)+(3.70*b)+(3.10*c)+(?4.11*a1*b)+(?1.57*a2*b)+(0.97*a2*c). In the preceding X and Y conditons, 0<X?2.5, 0<Y?3.5, at least one of a1 and a2 is greater than zero and less than 1.0, 0<b<1.0, 0<c<1.0, and a1+a2+b+c=1.0. Further, X is the filming performance of the detergent composition and Y is the spotting performance of the detergent composition. a1 is the weight fraction of the chelating component a1), a2 is the weight fraction of the chelating component a2), b is the weight fraction of the metal citrate, and c is the weight fraction of the metal carbonate. The weight fractions are based on the total amount of the chelating component, metal citrate and metal carbonate present in the detergent composition.

Abstract: Oily soil may be removed from a fabric by washing the oily soiled fabric in a heated (e.g., between about 100° C. to about 200° C. aqueous solution containing a polyethylenepolypropylene diblock surfactant having about 30 to 35 moles of propylene oxide (PO) and about 38 to 50 moles of ethylene oxide (EO).
