  • Patent number: 6951837
    Abstract: A process for detergent composition which has improved solubility or dissolution in laundering solutions, especially in solutions kept at cold temperatures (i.e., less than about 30° C.), is disclosed. The process includes mixing in at least one high-speed, low-speed, or a moderate-speed mixer, and various combinations of such mixers, at least two materials selected from the group consisting of dry agglomerates, wet agglomerates, spray dried granules, and detergent adjunct ingredients to form particles. Optionally a conditioning apparatus may also be used. The granular detergent composition made from this process is aesthetically pleasing to consumers and has improved flowability.

  • Patent number: 6596683
    Abstract: Disclosed is a process for making a granular detergent composition comprising the steps of: (a) granulating a detersive material comprising a detergent surfactant and a builder; and (b) coating an inorganic aqueous solution on the granules substantially to coat the granules.

  • Patent number: 6015784
    Abstract: Secondary (2,3) alkyl sulfate surfactants are admixed with an organic material such as a polyacrylate, and the resulting mixture is compacted into chips. The chips are comminuted to provide particles and the particles are coated with a free-flow aid. The resulting particles exhibit improved solubility and are especially useful in laundry detergents.

  • Patent number: 5955418
    Abstract: A process for preparing detergent particles containing secondary (2,3) alkyl sulfate surfactant comprises admixing secondary (2,3) alkyl sulfate surfactants with powdered detersive ingredients and admixing the resulting powder with a surfactant paste. The resulting detergent dough is extruded through an orifice and sized to provide particles. The particles are coated with a free-flow aid. The resulting detergent particles exhibit improved solubility and are especially useful in laundry detergents.

  • Patent number: 5919747
    Abstract: Preparation of secondary (2,3) alkyl sulfate particles comprises admixing secondary (2,3) alkyl sulfate surfactants with a deagglomerating agent such as zeolite or silica. The resulting powder is agglomerated with a nonionic surfactant, and formed into particles. The particles are then coated with a free-flow aid. Secondary (2,3) alkyl sulfate particles treated in this manner have improved solubility characteristics for use in laundry detergents.
