  • Patent number: 11578291
    Abstract: An improved cleaning composition in block form is described. The composition addresses the consumer issues of having a clear product that remains clear through the life of the product and also has favorable handling properties such as a high melting point and increased hardness. The improvements are the result of three essential ingredients of particular block copolymer nonionic surfactants, alkanecarboxylic salts, and particular solvents at restricted proportions in the overall composition that are molded into a cleaning composition in block form that exhibits a high melting point, hardness and high optical transmittance.
    Type: Grant
    Filed: March 26, 2021
    Date of Patent: February 14, 2023

  • Publication number: 20190256808
    Abstract: The invention relates to a granular cleaning agent for sanitary facilities, comprising tensides, alkane carboxylic acid salts, and solvents, wherein the proportion of alkane carboxylic acid salts equals between 1 wt % and 5 wt % and the proportion of solvents (including perfume oils) equals less than 40 wt % and the agent contains at least 18% non-ionic tensides from the group of block copolymers containing oligo and polyethylene oxides and/or oligo and/or polypropylene oxides and/or oligo and/or polybutylene oxide.

  • Patent number: 10047322
    Abstract: Agent for removing spots or deposits from hard or soft surfaces. The agent includes surfactants, an adhesion promoter, and at least one active substance, wherein the adhesion promoter is selected from the group of the alkylene-styrene copolymers, the olefin homopolymers or olefin copolymers of two or more olefins, wherein the polymers can also be hydrogenated, and the polyalkylene derivatives, the active substance is an acid, an alkali, a bleaching agent, and/or hydrophobic organic solvent not bound in a gel, and the agent includes either at least 10 wt % of at least one acid or at least 10 wt % of at least one alkali and/or at least 5 wt % of a bleaching agent and/or includes at least 10 wt % of hydrophobic organic solvent not bound in a gel.
