  • Patent number: 9289498
    Abstract: To provide a thickening composition which exhibits excellent feelings in use, namely, exhibits excellent freshness, non-stickiness and blend into skin feeling, and does not leave any residue on skin, which can stably keep the viscosity thereof in a low to moderate-level viscosity range and which, even when a salt-type ingredient is incorporated therein, does not undergo viscosity change, and also a cosmetic preparation containing the composition. A thickening composition which comprises (a) from 0.1 to 2% by mass of a specific hydrophobic denatured polyether urethane (associative thickener) and (b) from 0.1 to 2% by mass of a microgel to be obtained by grinding a gel of a hydrophilic compound having a gelling capability, in a ratio of component (a)/component (b) of from 0.1/0.9 to 0.9 to 0.1 (by mass), and which has a viscosity of from 50 to 50,000 mPa·s (with BL-type viscometer, 12 rotations, 25° C.); and a cosmetic preparation containing the thickening composition.

  • Patent number: 9241884
    Abstract: Provided is a redispersible powder-dispersed cosmetic which has a clear supernatant when unused, can exhibit good powder redispersibility when shaken upon use, has a good sensation, e.g., smoothness and non-stickiness, upon application to the skin, and has an excellent effect of dissolving/removing keratotic plugs. The cosmetic is characterized by comprising (A) succinic acid and/or a salt thereof, (B) bentonite and (C) a hydrophilic surfactant. Particularly preferably, the cosmetic additionally comprises a cellulose powder. It is preferred that the component (A), i.e., succinic acid and/or the salt thereof, is contained in an amount of 0.01 to 10.0 mass % relative to the total amount of the cosmetic.

  • Patent number: 8159656
    Abstract: A first step of measuring a change over time in the spectral transmission spectrum of a measurement sample by its exposure to the light of a light source including an ultraviolet radiation for a preset light exposure time, a second step of performing a correction according to the change over time in the spectral transmission spectrum of the measurement sample based on the result of the measurement obtained by the first step, and a third step of calculating the final in vitro predicted SPF of the measurement sample using the result of the correction obtained by the second step are included.
