Claims
- 1-23. (Canceled)
- 24. A granular or powdered detergent composition, comprising:
first particles comprising a methyl ester sulfonate consisting essentially of a C16 or C18 methyl ester sulfonate, wherein the first particles are substantially free of substances that cause more than a minor amount of additional disalt formation; and second particles comprising a detergent component; the first particles post-added to the second particles, whereby the first and second particles are commingled, but remain separate and physically distinct.
- 25. The composition of claim 24, wherein the C16 or C18 methyl ester sulfonate is a sodium methyl ester sulfonate.
- 26. The composition of claim 25, wherein the methyl ester sulfonate is a C16 sodium methyl ester sulfonate.
- 27. The composition of claim 24, wherein the detergent component comprises a nonionic surfactant, a builder, a secondary anionic surfactant, a polymer dispersant, an oxidizing agent, a biocidal agent, a foam regulator, a binder, an anticaking agent, an activator, a catalyst, a thickener, a stabilizer, a fragrance, a soil suspending agent, a soil release agent, a filler, a brightener, a UV protectant, an enzyme, or a mixture thereof.
- 28. The composition of claim 27, wherein the builder is sodium silicate, polysilicate, amorphous silicate, phyllosilicate, soda ash, or silicated soda ash.
- 29. The composition of claim 24, wherein the composition is substantially free of secondary anionic surfactant.
- 30. A granular or powdered α-sulfofatty acid ester detergent composition, comprising:
first particles comprising a methyl ester sulfonate consisting essentially of a C16 or C18 methyl ester sulfonate, the particles being substantially free of substances that cause more than a minor amount of additional disalt formation; and detergent particles comprising a nonionic surfactant and at least one other detergent component; the first particles post-added to the detergent particles, whereby the first particles and detergent particles are commingled, but remain separate and physically distinct in the detergent composition, and whereby additional di-salt formation is reduced.
- 31. The composition of claim 30, wherein the first particles are a powder.
- 32. The composition of claim 30, wherein the methyl ester sulfonate is a sodium methyl ester sulfonate.
- 33. The composition of claim 30, wherein the methyl ester sulfonate is a C16 methyl ester sulfonate.
- 34. The composition of claim 30, wherein the other detergent component comprises a builder, a secondary anionic surfactant, a polymer dispersant, an oxidizing agent, a biocidal agent, a foam regulator, a binder, an anticaking agent, an activator, a catalyst, a thickener, a stabilizer, a fragrance, a soil suspending agent, a filler, a brightener, a UV protectant, an enzyme, or a mixture thereof.
- 35. The composition of claim 30, further comprising adjuvant particles.
- 36. The composition of claim 35, wherein the adjuvant particles comprise an enzyme, a fragrance or an oxidizing agent.
- 37. A granular or powdered α-sulfofatty acid ester detergent composition prepared by:
providing at least one detergent component that causes more than a minor amount of additional di-salt formation; forming the at least one detergent component into detergent particles by granulating, spray drying or agglomerating; and post-adding powdered or agglomerated methyl ester sulfonate particles consisting essentially of a C16 or C18 methyl ester sulfonate to the detergent particles so that the methyl ester sulfonate particles and detergent particles are commingled, but remain separate and physically distinct; whereby the amount of the di-salt formation is reduced.
- 38. The composition of claim 37, wherein the methyl ester sulfonate particles are free of components that cause more than a minor amount of additional di-salt formation.
- 39. The composition of claim 37, further prepared by:
reducing the free moisture content of the detergent particles to between about 1 to about 6 weight percent.
- 40. The composition of claim 37, wherein the detergent particles are a powder, pellets, beads, or granules.
- 41. The composition of claim 37, wherein the methyl ester sulfonate is a sodium methyl ester sulfonate.
- 42. The composition of claim 41, wherein the methyl ester sulfonate is a C16 sodium methyl ester sulfonate.
- 43. The composition of claim 37, further prepared by:
applying a coating to the methyl ester sulfonate particles.
