  • Patent number: 6946138
    Abstract: A dilatant composition comprises (A) an o/w emulsion comprising an ionic surfactant, a water phase, and an oil phase which comprises a ceramide or a linear or branched, saturated or unsaturated C12-C32 fatty acid, wherein the oil phase is in a form of oil droplets having an average droplet size of from 0.01 to 0.2 ?m; and (B) a nonionic, water-soluble polymer having an average molecular weight of at least 300,000. The dilatant composition according to the present invention is excellent in dilatancy that its viscosity is low when left over standstill but increases abruptly when an external force of a certain intensity or higher is applied, and is useful in a wide variety of fields, e.g., cosmetic preparations such as humectants and massaging aids, shock absorbing agents and materials applied to around automotive crankcases.

  • Publication number: 20040071747
    Abstract: Cosmetics containing the following components (A) and (B): (A) an oil-absorbing powder having a squalane-absorbing ability of 1 ml/g or more; and (B) a compound having an affinity for component (A) lower than that of sebum, and having an ability to absorb the sebum and release component (B) in exchange for the sebum when the cosmetic is applied onto the skin. These cosmetics can adequately absorb the sebum and thus exhibit excellent effects of relieving or preventing oiliness of the skin and worsening in makeup. By selecting an appropriate compound to be released in exchange for the absorbed sebum, a substance capable of improving the skin qualities such as moistness, tightness, and tension can be allowed to penetrate into the skin. Moreover, a bodily feeling of the removal of the sebum can be imparted to users thereby.
