  • Patent number: 6774095
    Abstract: Disclosed is a detergent composition characterized by low skin irritation, good foamability, easy handling at the time of manufacture, and excellent stability when stored as a product. The detergent composition is a composition which contains a specific amount of (A) a specific amide alcohol and (B) at least one surfactant selected from an anionic surfactant, a nonionic surfactant, and an amphoteric surfactant, wherein the pH (25° C.) of the 20-fold diluted aqueous solution of the composition is 4.5 to 6.8.
    Type: Grant
    Filed: May 7, 2002
    Date of Patent: August 10, 2004
    Assignee: Kao Corporation

  • Patent number: 6407054
    Abstract: There is provided a surfactant composition for detergents, which has its high detergency and foamability within a broad pH region even in the presence of solids. It has its excellent foamability, thickening property, water solubility and stability. The composition contains a component (a) represented by the following formula (I) and at least one component (b) represented by the formula (II) and (III), in the total amount of 0.1 to 80% by weight, at the ratio of (a)/(b) by weight of from 99.9/0.1 to 70/30. In the formula (I), R1CO— is a saturated or unsaturated acyl group which has 6 to 24 carbon atoms and which may have hydroxy group; R2 is a linear or branched alkyl group having 1 to 3 carbon atoms; and R3 is a linear or branched alkylene or alkenylene group having 1 to 6 carbon atoms.
