  • Publication number: 20110083282
    Abstract: An apparatus and a method for decolorizing a denim fabric with an oxidizing gas is disclosed. The process is initiated by producing compressed air which is processed to generate dry air. The air pressure of dry air is reduced to maintain at 10 psig and thereby generates ozone gas. A negative pressure is maintained to ensure no ozone leak out to ambient from a washer. The denim fabric may be exposed to a controlled amount of ozone gas for a predetermined time such as a process time. Whenever the process time expires, the amount of ozone gas is converted back to oxygen by running a variable speed motor at high speed to create a negative pressure within the processing unit and released to atmosphere. The method also incorporates a means for monitoring the level of ozone concentration in ambient for the safety of operators.

  • Patent number: 7708021
    Abstract: A composition and method for simultaneously lightening and coloring hair. The composition generally consists of three components, specifically, a bleaching composition, an oxidizing composition and a dyeing composition. The composition preferably lightens hair color by a plurality of levels and simultaneously deposits tones that are attractive and long lasting. In a preferred embodiment, the bleaching composition is a powder composition based on silicate and/or carbonate salts and/or persulfate salts of ammonium, potassium or sodium. The persulfate bleaching composition can be ammonia-free, if desired. The oxidizing composition is preferably an anhydrous hydrogen peroxide solution, or another source of oxygen. The bleaching composition can be mixed with the oxidizing composition to form an anhydrous creme that is applied to the hair.

  • Publication number: 20100087528
    Abstract: Disclosed herein are two-component enzymatic peracid generation systems and methods of using such systems wherein the first component comprises a formulation of at least one enzyme catalyst having perhydrolysis activity, a carboxylic acid ester substrate, and a cosolvent and wherein the second component comprises a source of peroxygen in water. The two components are combined to produce an aqueous peracid formulation useful as, e.g., a disinfecting or bleaching agent. Specifically, organic cosolvents are used to control the viscosity of a substrate-containing component and to enhance the solubility of the substrate in an aqueous reaction formulation without causing substantial loss of perhydrolytic activity of the enzyme catalyst.

  • Patent number: 7682403
    Abstract: A method for treating laundry is provided. The method includes steps of applying a bleaching and antimicrobial composition to laundry in a laundry washing machine at a first pH that favors bleaching properties and at a second pH that favors antimicrobial properties, wherein the first pH and the second pH are different, and draining the bleaching and antimicrobial composition from the laundry. The step of applying a bleaching and antimicrobial composition to laundry can include a step of washing the laundry with a detergent composition for the removal of soil. In addition, the step of applying a bleaching and antimicrobial composition to laundry can precede or follow a step of washing laundry with a detergent composition for the removal of soil. A bleaching and antimicrobial composition and a laundry washing machine are provided.
