  • Patent number: 10231920
    Abstract: A skin cleansing composition comprising the following components (A), (B), (C), (D), (E), (F), and (G): (A) from 0.5 to 20% by mass of an oil agent having a viscosity at 30° C. of more than 30 mPa·s, (B) from 0.5 to 20% by mass of an oil agent having a viscosity at 30° C. of 30 mPa·s or less, (C) from 1 to 15% by mass of a nonionic surfactant having an HLB of 10 or more and having a residue obtained by removing a hydrogen atom from at least one hydroxyl group in sugar, reducing sugar, or polyglycerin as a hydrophilic group, (D) from 1 to 15% by mass of a nonionic surfactant having an HLB of 8 or less, (E) from 10 to 60% by mass of a polyhydric alcohol, (F) from 10 to 50% by mass of water, and (G) from 4 to 45% by mass of a nonionic surfactant having an HLB of 10 or more and having a polyoxyethylene chain as a hydrophilic group, wherein the mass ratio of the component (A) to the components (B), (A)/(B), is from 0.

  • Publication number: 20060100115
    Abstract: A detergent composition which has excellent stability; moisturizes the skin while giving thereto neither a taut feel nor dry feel after cleansing; and enables smooth finger-combing and does not give hair a rough feel after shampooing. The detergent composition contains (A) an anionic surfactant and (B) trimethylglycine, wherein the components (A) and (B) are added at a weight ratio (A)/(B)=1/3.5 or greater but less than 4/1 and the pH of the original composition or the pH of the composition diluted with purified water to a concentration of use is adjusted to 2 or greater but less than 6.5.

  • Patent number: 5645138
    Abstract: A dilatant fluid-sealed vibration-insulating device includes a connection member to be connected to one member, a holder to be connected to another member, an insulator provided between the connection member and the holder, the insulator being made of a rubber-like elastic material, a main chamber and an auxiliary chamber serially provided below the insulator. A partition plate separates the main chamber and the auxiliary chamber from each other. An orifice is formed in the partition plate to communicate the main chamber and the auxiliary chamber with each other. An air chamber is provided into which the air is introduced. A diaphragm separates the air chamber from the auxiliary chamber, and a dilatant fluid is sealed in the main chamber and the auxiliary chamber. When vibrations having very low frequency of about 5Hz and a relatively large amplitude are inputted to the vibration-insulating device, the dilatant fluid exhibits a relatively small viscosity increase insufficient to dampen the vibrations.

  • Patent number: 5267726
    Abstract: A hydraulic damping device for preventing the transmission of vibrations of wide-ranging frequencies. The device includes a thick vibration damping rubber body which defines a main liquid chamber therewithin, first and second deformable rubber diaphragms which respectively define first and second auxiliary liquid chambers, first and second passageways for respectively connecting the auxiliary liquid chambers to the main liquid chamber, each passageway generating liquid resonance in a predetermined frequency vibration range different from each other, and a bottom plate for defining a pressure chamber with the first deformable rubber diaphragm which defines the first auxiliary liquid chamber connected with the main liquid chamber by the first passageway generating liquid resonance in a high-frequency vibration range. The pressure chamber is selectively brought into communication with the atmosphere or a negative pressure source.
