  • Patent number: 4510073
    Abstract: A method for granulating a cationic surfactant having good water dispersibility and good storage stability comprising the steps of:(i) mixing 100 parts by weight of a powdered di (long-chain alkyl) quaternary ammonium salt having an average particle diameter of 150 .mu.m or less with 10 to 30 parts by weight of finely divided silica having an average primary particle diameter of 0.1 .mu.m or less;(ii) adding 20 to 80 parts by weight of a self-adhesive substance to the resultant mixture in the step (i), followed by granulation; and(iii) adding 30 to 150 parts by weight of at least one member selected from the group consisting of finely divided zeolite having an average primary particle diameter of 0.1 to 10 .mu.m, finely divided calcium carbonate having an average primary particle diameter of 0.01 to 10 .mu.m, and a mixture thereof, followed by granulation.

  • Patent number: 4287102
    Abstract: A detergent composition, suitable for use in washing vegetables and dishes and shampooing human hair, having both good detergency and little hand roughening action is presented. This detergent composition contains:(a) a water-soluble salt of olefin sulfonic acid having 12 to 16 carbon atoms and(b) a tertiary amine oxide having the formula ##STR1## wherein R.sup.1 is an alkyl group of 10 to 14 carbon atoms, and R.sup.2 and R.sup.3 are independently an alkyl or hydroxyalkyl group, of 1 to 3 carbon atoms. The contents of each of said components (a) and (b) in the composition being within the range of from 2 to 20% by weight, and the mol ratio of the component (a) to the component (b) being within the range of from 1.5/1 to 0.5/1, and the pH of an aqueous solution of the detergent composition being within the range of from 7.3 to 8.0 at the concentration when it is used in washing vegetables and dishes.

  • Patent number: 4259216
    Abstract: A production process of a liquid detergent composition having both good detergency and little hand roughening action is presented. This liquid detergent composition can be produced by mixing an anionic surface active agent and a semi-polar nonionic surface active agent, each in the stage of an aqueous solution, and then, adding a specified arylsulfonic acid to this mixture in such a manner that the produced liquid detergent composition contains 6 to 25% by weight of the anionic surface active agent, 2 to 8% by weight of the semi-polar nonionic surface active agent and 0.2 to 3.0% by weight of the arylsulfonic acid.

  • Patent number: 4235759
    Abstract: A liquid detergent composition which comprises an anionic surface active agent of polyoxyalkylene alkyl ether sulfate type and a cationic surface active agent of mono-long chain alkyl quaternary ammonium salt type at a mol ratio of the former to the latter in the range of from 8:1 to 1:1 is not only mild to the human skin but also capable of demonstrating superb detergency.
