  • Publication number: 20210395647
    Abstract: The present invention relates to a composition and a method for delaying laundry. The present invention provides a fabric treatment composition comprising: a solvent system in combination with surfactants, a hydrotrope, and a sequestrant, wherein the composition has a pH ranging from 2.5 to 5.0. The solvent system comprises a glycol ether; a diol; and a fatty acid ester. The composition of the present invention provides cleaning and anti-microbial benefits when used on a substrate.

  • 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.

  • Publication number: 20210122996
    Abstract: The present invention provides a detergent composition for use in a water-utilizing appliance, that allows for selection of an enhanced mode of operation of the appliance, based on the detection of a marker molecule in the solution of the detergent composition, where the enhanced mode comprises treatment of waste water generated during use of the appliance. The present invention also provides a method of selecting an enhanced mode of operation in a washing machine including a sensor assembly for detecting the presence of a marker molecule in a solution of the detergent composition.

  • Publication number: 20130327361
    Abstract: The present invention is in the field of laundry processes and devices. In particular the invention relates to the saving of water. It is an object of the present invention to reduce the water consumption in conventional washing methods, especially machine washing methods. It is found that the continuous pH controlled sequential dosing of an electrolyte, followed by dosing of a polymer and a solid liquid separation step during a full wash cycle of a washing machine, provides continuous clarification of the wash liquor and enables the continuous reuse of the water during said wash cycle.
