摘要:
The water-swellable clay mineral laminated powder of the present invention is characterized in that a layer of ionic molecule having two or more ionic functional group is laminated on the surface of a base powder particle, and a layer of water-swellable clay mineral is laminated thereon, and the layers are sequentially laminated so that the surface charge or the ionic charge of each layer is alternately positive and negative. The water-swellable clay mineral laminated powder of the present invention can impart new functionalities to the base powder easily, as a result of that the water-swellable clay mineral is stably laminated on the surface of the base powder. And the dye/water-swellable clay mineral complex of the present invention is characterized in that polybase and/or nonionic hydrophilic polymer and dye are complexed to water-swellable clay mineral. The dye/water-swellable clay mineral complex of the present invention is excellent for various resistance characteristics of the dye such as dissolution resistance, lightfastness, and chlorine resistance. In addition, the dye/water-swellable clay mineral complex is very useful as a water-type coloring agent since it has excellent coloring abilities, clearness, and dye fastness in water.

The present invention provides a method and composition which ameliorate inflammation, and suppress its onset, by allowing ATP receptor antagonists to act on ATP receptors of cells to block them and thereby inhibit the release of inflammatory cytokines, particularly interleukin-6 (IL-6) and/or interleukin-8 (IL-8), by the cells.
摘要:
The invention provides a screening method for active ingredients which exhibit effects of ameliorating pruritus, rough skin or sensitive skin, or effects of skin whitening, by inhibiting production and/or release of stem cell factor (SCF), as well as medicaments for pruritus, rough skin, sensitive skin and/or skin whitening which contain the active ingredients.
摘要:
A method for measuring skin absorbability of a substance, which includes measuring the amount of the substance which is penetrated into hair follicles; and using the resultant data as an index representing the amount of the substance which is absorbed through skin pores, to thereby determine the amount of the substance absorbed through skin pores and a method for measuring skin absorbability of a substance, which includes bringing the substance into contact with a first surface of a thin film that mimics the skin surface layer, a second surface of the film being brought into contact with artificial sebum; and evaluating the sebum transferability of the substance by using the degree of transfer of the substance to the artificial sebum as an index, are disclosed. A kit for performing the measurement method of the present invention is also disclosed.
摘要:

摘要:
A multi color changing powder with a bluish base appearance color of which color tone varies according to the observation direction is provided. A pleochroism powder of the present invention comprises a flaky mica having a coating which consists of two layers wherein one of said two layers is a first layer comprising a metal oxide of titanium coated on said flaky mica and the other is a second layer comprising metal oxides of cobalt and aluminum coated on said first layer.
摘要:
The present invention relates to a plasminogen activator inhibitor, an external preparation for skin comprising the same, a method for improving rough skin and in particular, to improvement of an effective inorganic component. A plasminogen activator inhibitor contains a specific zinc oxide which adsorbs a plasminogen activator and effectively inhibits its activity. When it is used as an external preparation for skin, excellent improvement of rough skin is obtainable. Further when silica-coated zinc oxide is applied as an external preparation for skin, excellent improvement effect and prevention effect for rough skin are obtainable without an intolerance sensitivity reaction in the case of morbid dermatitis such as atopic dermatitis.

An immunopotentiator for preventing ultraviolet light-induced skin immunosuppression or a drug against ultraviolet light-induced skin immunosuppression which contains glutathione or Scutellaria root extract. Also, an immunopotentiator or a drug against immunosuppression which contains linden extract, clove extract, Geranium herb extract or rosemary extract. They can prevent a reduction of immune functions due to ultraviolet light.
摘要:
A stimulative perfume composition which demonstrates an excellent stimulative effect uses an anisaldehyde as the stimulative agent. The stimulative perfume composition includes an effective amount of the anisaldehyde in perfume ingredients.
摘要:
An observation device for observing a reproduced image which is reproduced by an image reconstructor uses a special light different from normal light. A special image reproducing and observing device 2 enables observation of reproduced image by irradiating an image reconstructor 4 with a special light to reproduce an image. The special image reproducing and observing device 2 has: light sources 6 and 8 which produce special light; a power supply 10 which causes a light emission by the light sources 6 and 8; and a irradiation device 8 and 12 which enables irradiation of an image reconstructor 4 with a special light that is produced at the light source 6 and 8.
