  • Patent number: 6653272
    Abstract: A detergent composition that contains inorganic powder and a soap such as a soda soap, wherein the inorganic powder is zeolite powder, calcium carbonate powder, silica powder, ceramic powder, alga fossil powder, seashell powder or the like, and pineapple enzymes are fixed thereto by adding pineapple juice thereto and fermenting. This detergent composition does not cause water pollution like synthetic detergents do, thus enabling water pollution caused by wastewater from cleaning to be prevented. Moreover, due to the positive water-cleaning action of the pineapple enzymes, the detergent composition cleans the insides of drainage pipes, purifier tanks and the like, thus improving the functions thereof. Water pollution can thus be ameliorated.

  • Patent number: 6602842
    Abstract: Novel cleaning compositions comprising cell wall degrading enzymes are disclosed having pectinases and/or hemicellulases and optionally cellulases. The compositions are particularly suitable for removing stains of vegetable origin, especially from textiles. Although compositions having only one type of such enzymes axe part of the invention (excluding cellulases alone), preferred embodiments have a mixture of cell wall degrading enzyme activities to allow for a concerted action against the fibrous mass which usually constitutes a stain of vegetable origin.

  • Patent number: 6586384
    Abstract: A method of delivering a benefit agent to a selected area of a fabric for exerting a predetermined activity, wherein the area is pre-treated with a multi-specific binding molecule which has a high binding affinity to said area through one specificity and is capable of binding to said benefit agent through another specificity, followed by contacting said pre-treated area with said benefit agent, to enhance said pre-determined activity to said area. Preferably, the binding molecule is an antibody or fragment thereof, or a fusion protein comprising a cellulose binding domain and a domain having a high binding affinity to another ligand which is directed to said benefit agent. The method is useful for stain removal, perfume delivery, and treating collars and cuffs for wear.

  • Patent number: 6500212
    Abstract: The present invention is directed to a method for treating a material to impart wrinkle reduction and temporary crease resistance thereto, and improve feel. The method involves: applying to said material a solution of a treatment composition in an amount effective to impart temporary crease and stain resistance, said fabric treatment composition comprising a hydroxy urea or hydroxy amide compound; and allowing said treatment composition to dry at ambient temperature, wherein said hydroxy urea compound comprises one urea and at least one hydroxyl group and said hydroxy amide compound comprises at least one amide group and at least one hydroxyl group. The material treatment is useful in reducing wrinkles in clothing, improving the feel of fabrics, and increasing the moisture adsorbence and retention in natural and synthetic fabrics.

  • Patent number: 6454814
    Abstract: A method of treating a fabric including cellulose fiber to increase water absorption and hydrophilicity by graft polymerisation. The method includes pre-treating the fabric in a solution of an inhibitor for about one hour, and washing the fabric to remove excess inhibitor solution. The fabric is placed in a grafting solution of a hydrophilic monomer for about three hours, washed in methanol, and decrystallized in a solution of zinc chloride for about one hour. The decrystallised fabric is then treated in a solution of sodium hydroxide at 50° C. for about one hour.
