Abstract:
Provided is a method for stably sticking a sheet to skin for a long time without giving a skin stress and strange feeling of appearance. In the present disclosure, a self-supporting cellulose membrane having a thickness of not less than 20 nm and not more than 1,300 nm and containing regenerated cellulose having a weight average molecular weight of not less than 150,000 is used, and after applying to skin an aqueous cosmetic agent containing water and at least one polyhydric alcohol and having a content of glycerin of the polyhydric alcohol of 0% by weight to 15% by weight, the cellulose membrane is stuck to the position of the skin on which the cosmetic agent is applied.
Abstract:
A device for printing a functional material on a biocompatible thin-film is provided, including: a feeder for feeding a thin-film sheet including the biocompatible thin-film and a first support into the printing device; a controller for loading makeup information for printing the functional material on the thin-film; a printing unit for printing the functional material corresponding to the makeup information on the thin-film based on a makeup signal from the controller; a feeder for feeding a second support into the device; a transfer unit for transferring a thin-film printed body, the thin-film on which the functional material is printed by the printing unit from the first support to the second support; and a delivery unit for delivering the transferred thin-film printed body to outside the device. This configuration enables people who lack sufficient makeup knowledge, techniques, or time to apply makeup easily, quickly, and safely.
Abstract:
The present invention provides an ionic liquid represented by the following chemical formula, [(CH3)3N(CH2)2OH]+[NH2(CH2)3CH(NH2)COO]−. The present invention provides an ionic liquid capable of dissolving cellulose within twenty-four hours.
Abstract:
A method of producing an adhesive sheet for skin includes attaching a water-absorptive support to a water-permeable biocompatible film to prepare a stack including the biocompatible film and the support, applying an aqueous ink including water and a functional material to the biocompatible film side of the stack thereby to fix the functional material to the biocompatible film, and separating the biocompatible film having the functional material fixed thereto from the support. An adhesive sheet for skin comprises a water-permeable biocompatible film to which an aqueous ink including water and a functional material has been applied and fixed and a water-absorptive support detachably attached to the biocompatible film.
Abstract:
A cellulose membrane according to an embodiment of the present disclosure is a self-supporting cellulose membrane having a thickness of between 20 nm and 1300 nm, inclusive, composed of regenerated cellulose having a weight average molecular weight of 150,000 or more.
Abstract:
The present invention provides an ionic liquid composition containing an ionic liquid and water. The ionic liquid composition does not contain an enzyme capable of hydrolyzing cellulose. The ionic liquid is represented by the following chemical formula (I): [(CH3)3N(CH2)2OH]+[NH2-L-CHNH2—COO]− (I); where L is absent or a linker. A molar ratio of [(CH3)3N(CH2)2OH]+ to [NH2-L-CHNH2—COO]− is not less than 0.87 and not more than 1.14. A weight ratio of the water to the ionic liquid composition is not more than 7.3%. The present invention provides an ionic liquid composition capable of dissolving cellulose without a cellulose-degrading enzyme, namely, an enzyme capable of hydrolyzing cellulose.
Abstract:
The present invention provides an ionic liquid represented by the following chemical formula (I): [(CH3)3N(CH2)2OH]+[NH2-L-COO]− (I) where L is —(CH2)2— or —(CH2)3—. The present invention also provides an ionic liquid composition containing an ionic liquid; and water. The ionic liquid is represented by the above chemical formula (I). A molar ratio of [(CH3)3N(CH2)2OH]+ to [NH2-L-COO]− is not less than 0.86 and not more than 1.12. A weight ratio of the water to the ionic liquid composition is not more than 4.7%. The present invention provides an ionic liquid capable of dissolving cellulose without an cellulose-degrading enzyme (namely, an enzyme capable of hydrolyzing cellulose).
Abstract:
An inkjet printing ink according to the present disclosure contains a pigment, acrylic particles, an alcohol, and water. The alcohol contains at least a trihydric alcohol. A ratio of an amount of the alcohol to a whole mass of the inkjet printing ink is 30% by mass or less. A ratio of an amount of the acrylic particles to a mass of the pigment is 5% by mass to 100% by mass. Further, the inkjet printing ink has negative skin irritation.
Abstract:
A transfer device is provided for transferring, to an adherend, a thin-film to which a functional material adheres, the transfer device including a plurality of rollers for providing a rotating function, and an endless belt installed on the plurality of rollers, wherein, on the endless belt, the transfer device retains the thin-film with a surface of the thin-film to which the functional material adheres being in contact with the endless belt, and the transfer device transfers the thin-film to the adherend so that a surface opposite a surface of the thin-film to which the functional material adheres is in contact with the adherend. This configuration allows an ultrathin thin-film to be simply transferred to the adherend such as a human body without damage to the thin-film, the thin-film having the adhered functional material and requiring careful handling.
