  • Patent number: 6767882
    Abstract: A process for preparing detergent particles having a coating layer of water-soluble inorganic material is provided. The detergent particle comprises a particle core of a detergent active material. This particle core is then at least partially covered by a particle coating layer of a water soluble inorganic material. Particularly preferred are non-hydrate inorganic coating materials including double salt combinations of alkali metal carbonates, and sulfates. The particle coating layer may also include detergent adjunct ingredients such as brighteners, chelants, nonionic surfactants, co-builders, etc. The process includes the steps of passing the particle core through a coating mixer such as a low speed mixer of fluid bed mixer and coating the particle core with a coating solution or slurry of the water soluble inorganic material.

  • Patent number: 6756353
    Abstract: Detergent compositions or components are formulated with certain hydrophobically modified cellulosic materials, which provide protection of fabrics, whereof at least 80% or even at least 90% have a particle size of below 1000 microns or even below 850 or even 710 microns. Selection of materials of this particle size results in improved dispersability of the cellulosic material and imparts improved appearance and integrity benefits to fabrics and textiles laundered in washing solutions from such compositions.

  • Patent number: 6752330
    Abstract: A liquid sprayer is provided. This liquid sprayer includes a bottle having an opening and a sprayer housing attached to the bottle. This sprayer housing includes an electrical motor, a voltage source for powering the electrical motor, a pump driven by the motor, a switch for completing an electrical circuit, a nozzle mechanism attached to the sprayer housing for spraying a liquid. The liquid sprayer also includes a deformable “pinched tube” mechanism which prevents liquid from flowing through the nozzle when the sprayer is not being used. The sprayer housing also includes a trigger movably connected to the sprayer housing for closing the switch, translating the piston and creating a leak-tight seal by squeezing the “pinched tube”.

  • Patent number: 6743761
    Abstract: A one step method for the treatment of a non-finished textile component is provided. The method comprises the combination of a bleaching and de-sizing treatment steps into a single step and comprises treating a non-finished textile component in an aqueous treatment solution of a hydrophobic bleaching system and a de-sizing system. Preferred hydrophobic bleaching systems are combinations of hydrogen peroxide and a hydrophobic bleach activator or a hydrophobic peracid. Preferred bleach activators include the alkanoyloxybenzene sulfonates and in particular noanoyloxybenzene sulfonate. The method provides superior fiber protection and fabric strength benefits versus conventional processing as well as allows significant savings in both energy and time due to the elimination of multiple washing and/or drying stages and lower bleaching temperatures.

  • Patent number: 6730654
    Abstract: Antimicrobial, hard surface cleaning compositions that effectively clean and reduce microorganisms on a surface without resulting in unacceptable filming and/or streaking residue on the surface, generally comprise (a) cationic antimicrobial active; (b) nitrogen-containing polymer; and (c) surfactant. Preferred antimicrobial, hard surface cleaning compositions for use in no-rinse cleaning methods comprise (a) from about 0.001% to about 0.5%, by weight of the composition, of surfactant; (b) cationic antimicrobial active; and (c) nitrogen-containing polymer. Methods of cleaning and reducing microorganisms on hard surfaces comprises contacting the surfaces with such compositions and preferably allowing the compositions to dry on the surface without rinsing the composition from the surface using water or other rinsing solution.
