  • Patent number: 9132103
    Abstract: The present invention relates to a method of disinfecting a surface and to antimicrobial composition, particularly for personal cleaning, oral care, or hard surface cleaning. It is an object of the present invention to provide for an antimicrobial composition that has relatively fast antimicrobial action. The inventors have found that use of small amounts of eugenol in combination with thymol and terpineol enables this fast kinetics at much lower amount of thymol and terpineol than without eugenol.

  • Publication number: 20130316027
    Abstract: The invention relates to an antimicrobial composition. The invention more particularly relates to a composition comprising a combination of two materials that interact synergistically to provide virus kill in a short time. The present inventors have found that a combination of a cationic surfactant e.g. benzalkonium chloride and an extract of a rhizome viz. Curcuma or its active ingredient viz. curcumin provide this fast antiviral action.

  • Publication number: 20130269733
    Abstract: The present invention is in the field devices for hand washing, in particular the washing and drying of hands in public bathrooms. Accordingly it is an object of the present invention to provide a device for cleaning hands, especially a device for wetting hands, depositing a cleansing and/or disinfecting composition and rinsing consecutively, using a low amount of water. It has been found that an air-water jet nozzle assembly comprising two nozzles wherein a first nozzle is in fluid communication with a feed liquid source; and a second nozzle connected to a source of compressed air may be used to clean hands using low amounts of water in a short time.
