A skin diagnosing device 1 includes an optical unit 2 including: an optical system that uses the OCT; an optical mechanism 4 to guide light from the optical unit 2 to skin S to scan the skin; a loading device 5 to apply predetermined deformation energy to the skin S; a control computation unit 6 to compute tomographic distribution of predetermined status values relating to the skin S by controlling driving of the loading device 5 and the optical mechanism 4 and processing optical interference signals output from the optical unit 2 in response to the driving, to compute an evaluation value of the skin S on the basis of the tomographic distribution; and a display device 74 to display the evaluation value of the skin S. The control computation unit 6 computes the evaluation value by computing mechanical characteristics and a blood flow condition of the skin S as the status values and associating the mechanical characteristics and the blood flow condition at a cross-sectional position of the skin S.
摘要:
The present invention provides a sunscreen cosmetic comprising, relative to the total amount of the sunscreen cosmetic, 10-90 wt% of agar microgel (wherein the agar content in the agar microgel is 0.4-1 wt%) and 0.1-5 wt% of a water soluble ultraviolet absorbent. It was necessary to blend in an organic ultraviolet absorbent and such to give sunscreen cosmetics a high SPF value. However, there was a problem in that it was hard for a water soluble ultraviolet absorbent in the formulation to achieve the expected SPF function. Also, sunscreen cosmetics are particularly desired to give a freshing texture upon use. In view of the fact that a high blend ratio of an oil soluble ultraviolet absorbent inhibits the freshing texture upon use, the object of the present invention is to provide a sunscreen cosmetic that achieves a high SPF value and a freshing texture upon use by mainly blending in a water soluble ultraviolet absorbent.
摘要:
The present invention provides a copolymer used as oily gelling agent with which a stable oily gelled composition can be prepared. The copolymer of the present invention is characterized by comprising a hydrophobic monomer represented by the following general formula (1) and a hydrophilic monomer represented by the following general formula (2) and/or the following general formula (3). (In formula (1), R 1 is a straight-chain or branched-chain alkyl group having 16 to 22 carbon atoms. R 2 is a hydrogen atom or a methyl group.) (In formula (2), R 3 is a hydrogen atom, a glyceryl group, a straight-chain or branched-chain hydroxyalkyl group having 1 to 4 carbon atoms, or a polypropylene glycol group represented by -(C 3 H 6 O) n H (here, n is an integer of 2 to 10). R 4 is a hydrogen atom or a methyl group.) (In formula (3), R 5 is a hydrogen atom or a methyl group, R 6 is a straight-chain or branched-chain alkyl group or hydroxyalkyl group having 1 to 4 carbon atoms, or a substituent represented by the following structural formula (4).)
摘要:
An aerosol cosmetic exhibits an improved feeling of use while having high UV blocking properties. An aerosol cosmetic is filled up as a bulk solution together with a propellant in a pressure-resistant container and includes ethyl alcohol that is a main dispersion medium, an organic ultraviolet absorber, and an ester oil. The organic ultraviolet absorber includes an organic ultraviolet absorber that is solid at room temperature. The solid organic ultraviolet absorber is dissolved in the ester oil.
