  • Patent number: 5385737
    Abstract: Surfactant-containing seamless capsules of the present invention have an inner layer and an outer layer having a film-forming material. The inner layer contains an oily component and a surfactant component. Such surfactant-containing seamless capsules are produced using in multiple nozzle of triple or more having a sequentially increasing diameter. Since the capsules are excellent in emulsive dispersibility of the content liquid and surfactant dispersibility and solubility in the oily component, they can be used in pharmaceuticals, foods, luxury foods, bath additives, detergents and other fields.

  • Patent number: 5106623
    Abstract: An extracted peach-leaf fraction, preparation method of the same and a bath-additive composition comprising the same is disclosed.The extracted peach-leaf fraction is prepared by extracting peach-leaves with water and/or a lower alcohol, and treating the obtained extract with activated charcoal.The peach-leaf fraction of the present invention has an excellent solubility and stability when dissolved in water, a high anti-inflammatory effect, and safety to the skin. Further, the bath-additive composition comprising the peach-leaf fraction has an excellent bathing effect without making the bath water turbid.

  • Patent number: 5002758
    Abstract: A bathing preparation containing (a) fumaric acid, (b) a carbonate, (c) from 0.1 to 20% by weight, based on fumaric acid, of carboxymethyl cellulose, or an alkali metal salt thereof, having a viscosity of not higher than 2,000 cp in a 1.0% by weight aqueous solution at 25.degree. C., or at least 0.2% by weight, based on fumaric acid, of polyethylene glycol, and (d) not less than 0.02% by weight and less than 0.1% by weight, based on fumaric acid, of a nonionic surface active agent having an HLB of 7 or more. The bathing preparation causes neither floating of fumaric acid or foaming when it is dissolved in a bath nor foaming after it is dissolved and the bath is agitated.

  • Patent number: 4451433
    Abstract: An automatic chemical analyzer suitable for chemically analyzing a number of analysis items is disclosed. Samples in sample containers are sequentially dispensed to an array of reaction vessels using a first pipetting tube. Reagent solutions selected in accordance with the analysis items are fed to the reaction vessels using a second conductive pipetting tube. The reaction solutions in the reaction vessels are measured by a photometer. When the reagent solutions are sucked into the second pipetting tube, the liquid levels of the reagent solutions in the reagent containers are detected by a liquid level sensor formed by the second pipetting tube and a conductive electrode. The amounts of the reagent solutions remaining in the reagent containers are determined based on the position of the liquid level sensor and the numbers of times of dispense allowed to the reagent solutions with respect to the analysis items are displayed on a cathode ray tube.
