  • Publication number: 20180195022
    Abstract: A liquid detergent including: 3% by mass or more of an ?-sulfo fatty acid alkyl ester salt (a) represented by the general formula (I); 5% by mass or more of at least one type of surfactant (b) selected from sulfonic acid-type anionic surfactants, sulfuric acid ester-type anionic surfactants, and nonionic surfactants other than component (a); and a water-soluble magnesium salt (c), where the total content of component (a) and component (b) is from 8 to 35% by mass, the content of component (a) is 50% by mass or less with respect to the total mass of the surfactant, and a mass ratio represented by the formula: [ component ? ? ( c ) ] [ component ? ? ( a ) ] is from 0.1 to 1.5. R1—CH(SO3M)-COOR2 ??(I) where R1 is a hydrocarbon group having 14 to 16 carbon atoms, R2 is a hydrocarbon group having 1 to 6 carbon atoms, and M is a counter ion.

  • Patent number: 8993504
    Abstract: The present invention provides an oxidation catalyst for bleaching containing a component (a) which is an anion caused from a chelating agent having less than or equal to coordination position 5 and/or the chelating agent, and a component (b) which is a copper and/or manganese compound; and a binder compound (c); a hydrogen peroxide-based compound (d) which dissolves in water and generates hydrogen peroxide, the bleaching composition containing a granulated product or a molded product in which at least the component (b) and the component (c) are granulated or molded together. According to the invention, an oxidation catalyst that promotes the oxidation effect of hydrogen peroxide-based compounds with a trace amount of the composition, and has excellent effects of suppressing the decomposition of hydrogen peroxide-based compounds and suppressing coloration of the catalyst itself, and a bleaching composition containing the oxidation catalyst can be utilized.
