  • Patent number: 11034919
    Abstract: The present invention relates to a composition and a method for treating substrates, such as fabrics; in particular a composition that can deliver cleaning and anti-microbial benefits to the fabric thereby delaying laundry. There is a long left need for a composition, which can clean the fabric and deliver anti-microbial benefits without the use of water and detergents. It is therefore an object of the present invention to provide a composition with no surfactants in it which can deliver cleaning and anti-microbial benefits through a single product. It has been found that cleaning and anti-microbial benefits on fabric can be achieved by a solvent mix of a glycol ether, a fatty acid ester and a diol in combination with a bipolar antimicrobial particle in an aqueous solution.

  • Patent number: 9756855
    Abstract: The invention relates to an antimicrobial particle and to a composition for use in personal or home care products comprising the same. The invention also relates to a process for preparing the antimicrobial particle. The antimicrobial particle comprises thymol and terpineol incorporated in a cage-forming inorganic silicate or aluminosilicate particle which is coated with a coating material selected from a water soluble alkali or alkaline earth metal salt.

  • Patent number: 8910889
    Abstract: The present invention relates to a process and a device for cleaning substrates. In particular the invention relates to an air-water jet device connected to a detergent dosing system. It is therefore an object of the present invention to provide air-water jet device for cleaning fabric articles with enhanced performance; and to provide a dosing device for a detergent composition that may be connected to an air-water jet device. Surprisingly it has been found that a dispensing chamber for a detergent composition DET between the water source and the outlet of the water nozzle provides improved cleaning of an air-water jet.

  • Publication number: 20130289501
    Abstract: The present invention is in the field skin treatment, in particular and deep pore cleansing and delivery of benefit agents deep inside the pores. The invention further relates to air-water jet devices for providing said skin treatment. Accordingly it is an object of the invention to provide for a device and process for deep pore skin cleansing, especially, a process for skin cleansing using reduced amounts of water. We have found that a skin cleaning device comprising an air-water jet, wherein the air and water are mixed outside the nozzle(s), provides improved cleansing of skin, including deep poor cleansing, with low usage of water.

  • Publication number: 20120177712
    Abstract: This invention relates to a bipolar antimicrobial particle for use in laundry detergent compositions, fabric conditioners, personal care and cosmetic compositions and a process for making the same. In view of the foregoing, it is an object of the present invention to provide a stabile antimicrobial agent immobilised on a carrier particle. It is a further objective to provide an antimicrobial particle with improved retention to the fabric so that larger amounts of antimicrobial will be available even after rinsing. Surprisingly it has been found that antimicrobial molecules tagged by surface reaction onto naturally occurring asymmetric clay surfaces, act as an antimicrobial particle with improved retention properties with improved stability.
