  • Publication number: 20060288743
    Abstract: The present invention provides a peroxide generating device for application in an automatic fabric washing machine, comprising an electrochemical cell for the production of peroxide from tap water and air, and a pH modifying device for the production of acidic and alkaline water. Thereby enabling washing of the fabric articles without the need for added chemicals and improved fabric care, due to the separate dosing of peroxide.

  • Publication number: 20060080786
    Abstract: A dry cleaning process for in-home dry cleaning comprising a low-aqueous dry cleaning step of contacting a laundry article with a low-aqueous dry cleaning composition, wherein said composition comprises a non-flammable, non-chlorine containing organic dry cleaning solvent, water and surfactant, whereby the water to cloth ratio (w/w) is less than 0.45 and the water to surfactant ratio (w/w) is at most 1.5, wherein said organic dry cleaning solvent is selected from hydrofluorocarbon, hydrofluoroether and siloxane solvent.

  • Publication number: 20060054193
    Abstract: The present invention provides a cleaning method in which the feed water is consecutively contacted with an appropriate combination of cation exchange resin material and anion exchange resin material. As a result, wash amplified water (WAW) is produced having a pH value that is more than 0.5 pH unit different from the feed water and a water hardness of less than 5° FH. In this method, the resins are regenerated with the use of an electric field. In step (ii) of the cleaning method of the invention, the wash-amplified-water is mixed with a detergent product that is substantially builder-free and contains at least 10% wt of surfactant. This cleaning method is preferably a fabric washing or dishwashing method.

  • Publication number: 20060048307
    Abstract: A dry cleaning process for in-home dry cleaning comprising a low aqueous dry cleaning step of contacting a laundry article with a low aqueous dry cleaning composition wherein the liquor to cloth ratio (w/w) (LCR) is at most 20, and wherein said low aqueous composition comprises: a) at least one non-flammable, non-chlorine containing organic dry cleaning solvent; b) 0.01 to 0.9 wt. % water and c) a cleaning effective amount of a surfactant wherein said surfactant comprises at least one anionic headgroup.

  • Publication number: 20050148482
    Abstract: The invention provides a method of washing a laundry fabric in a wash liquor in a washing machine, wherein during a single wash cycle no more than 10% by weight of the wash liquor is drained from the washing machine, wherein said method comprises the step of varying the ionic strength of the wash liquor over at least 10% of the duration of the wash cycle by addition of one or more ionic ingredients to the wash liquor, and wherein the lowest ionic strength of the wash liquor is from 0.001 to 0.06 M and the highest ionic strength of the wash liquor is from 0.01 to 0.5 M.

  • Publication number: 20050130860
    Abstract: The invention provides a method of washing a laundry fabric in a wash liquor in a washing machine, said wash liquor containing surfactant material, wherein during a single wash cycle no more than 10% by weight of the wash liquor is drained from the washing machine, wherein the concentration of the surfactant material in the wash liquor is substantially constant during the wash cycle, and wherein said method comprises the step of changing the ionic strength of the wash liquor by addition of one or more ionic ingredients thereto during the wash cycle.

  • Patent number: 5417879
    Abstract: A detergent composition contains a combination of two different surfactants, one micellar phase and one lamellar phase, at least one of the surfactants being a glycolipid biosurfactant. Preferred micellar phase biosurfactants are rhamnolipids, sophoroselipids and cellobioselipids, advantageously used in combination with non-glycolipid anionic or nonionic surfactants; while preferred lamellar biosurfactants are trehaloselipids, glucoselipids, and rhamnolipids, advantageously used in combination with micelar biosurfactants. The detergent compositions show enhanced oily soil detergency in fabric washing even when the glycolipid biosurfactants used individually are poor detergents.
