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.

The present invention provides a sunscreen composition comprising (a) a surfactant, (b) water, (c) an oil component, and (d) a water soluble ultraviolet absorbent and/or oil soluble ultraviolet absorbent that is in the bicontinuous microemulsion phase at 25° C.The object of the present invention is to obtain a sunscreen composition that is superior in terms of the ultraviolet protection ability and the tactile sensation during use. Furthermore, its object is to provide a sunscreen composition composed of a transparent bicontinuous microemulsion phase that spreads well when applied on the skin, is superior in terms of the coating film uniformity and absorption into the skin.

摘要:
The present invention provides a sunscreen composition containing (a) a surfactant, (b) water, (c) an oil component, and (d) a water- and/or oil-soluble ultraviolet absorbent, that is in a bicontinuous microemulsion phase at 25° C. The transparent bicontinuous microemulsion spreads well when applied to the skin, to give a uniform and well-absorbed film.

摘要:
The present invention is to provide a nonaqueous electrolytic solution prepared by dissolving an electrolyte salt in a nonaqueous solvent, wherein the nonaqueous solvent includes 0.01 to 40% by volume of an ester having two alkyl groups at the α-position carbon of the carbonyl group and being represented by the following general formula (I), and an energy storage device. (in the above formula, R1 is an alkyl group, an alkenyl group or an alkynyl group in which at least one of the hydrogen atoms may be substituted with a halogen atom, R2 and R3 are an alkyl group in which at least one of the hydrogen atoms may be substituted with a halogen atom, and R2 and R3 may be linked to each other to form a ring. However, when R2 and R3 do not form a ring, R3 is an alkyl group in which at least one of the hydrogen atoms may be substituted with a halogen atom.).
摘要:
The present invention provides a nonaqueous electrolytic solution capable of improving electrochemical characteristics in a broad temperature range, such as low-temperature cycle properties and low-temperature discharge properties after high-temperature storage, and provides an energy storage device using the nonaqueous electrolytic solution. The invention includes (1) a nonaqueous electrolytic solution of an electrolyte salt dissolved in a nonaqueous solvent, which comprises from 0.001 to 10% by mass of a compound represented by the following general formula (I), and (2) an energy storage device comprising a positive electrode, a negative electrode, and a nonaqueous electrolytic solution of an electrolyte salt dissolved in a nonaqueous solvent, wherein the nonaqueous electrolytic solution is the nonaqueous electrolytic solution of (1). (In the formula, Y represents a group —C(═O)— or a group —S(═O)2—; R3 and R4 each independently represent an aryl group having from 6 to 10 carbon atoms in which at least one hydrogen atom is substituted with a halogen atom, or R3 and R4 bonding to each other represent a cycloalkanediyl group or a benzenediyl group, having from 5 to 12 carbon atoms. R represents —C(R1)(R2)— or -L-; R1 and R2 each independently represent a hydrogen atom, a halogen atom, or an alkyl group having from 1 to 4 carbon atoms; and L represents a divalent linking group having from 1 to 6 carbon atoms and optionally substituted with a halogen atom).
摘要:
In an image forming apparatus, photosensitive bodies are mounted in a first frame. Developing units are detachably mounted in the first frame. A second frame is movable relative to the first frame. Each developing unit is movable relative to the first frame between a separate position, at which a developing roller is separate from a photosensitive body, and a contact position, at which the developing roller is in contact with the photosensitive body. The second frame moves relative to the first frame, thereby moving the developing units relative to the first frame between the separate positions and the contact positions. The second frame positions each developing unit relative to the first frame in a direction to move the developing roller toward the corresponding photosensitive body when the developing unit is in the contact position.
