Abstract: Conventional hair cosmetic materials have difficulty in achieving both high improvement effects on damaged hair and excellent sensation upon use. The present invention provides an oil-based hair cosmetic material to realize hair cosmetics having both high improvement effects on damaged hair and excellent sensation upon use, and a production method of the same.

Abstract: Provided are acidic hair dye compositions in which the dye has a high permeability into hair, the dye can be applied uniformly, and the composition has excellent staining property, safety and sense of use at the time of hair dyeing. The acidic hair dye compositions of the present invention comprise at least one dibasic acid ester compound represented by general formula I below: wherein, in general formula I, R1 is an alkylene group which may have a substituent with 2 to 4 carbon atoms, R2 and R3 are, independently from each other, an alkyl group which may have a substituent with 1 to 4 carbon atoms, R4 and R5 are, independently from each other, hydrogen, methyl group or ethyl group, m and n is, independently from each other, an integer of 0 to 4, wherein m+n?1 (with the proviso that the case is excluded in which R2 and R3 are both ethyl group, and m and n are both 1).

Abstract: The present invention provides an oil agent having water solubility and oil solubility, as well as suppressed stickiness when applied to skin to exhibit excellent feeling of use, and also provides a lubricating agent, a moisturizing agent and an external preparation containing said oil agent. The oil agent of the present invention comprises a dibasic acid ester compound of general formula I: wherein R1 is an alkylene group having a carbon number of 2-4, which may be mono- or poly substituted, R2 and R3 are, independently of each other, an alkyl group having a carbon number of 1-4, which may be mono- or poly substituted, n and m are, independently of each other, an integer of 0-4 with m+n?1 (provided that the cases wherein both of R2 and R3 are an ethyl group and both of n and m are 1 are excluded).

Abstract: [Problems to be Solved] To provide an oil base having appropriate hardness and viscosity and excellent spreadability, a process for producing same, and a cosmetic material containing the oil base [Solution means] The oil base of the present invention is an oil base containing an ester condensate obtained by a reaction between polyglycerol, 12-hydroxystearic acid, and hydrogenated dimer acid, the oil base having a three-dimensional network structure in which hydrogenated dimer acid is condensed with a hydroxyl group of each of the polyglycerol and 12-hydroxystearic acid.

Abstract: A solid cosmetic comprising components (A), (B), (C), and (D) below: (A) a polyamide resin; (B) diisostearyl malate; (C) a polyglyceryl isostearate; and (D) a liquid oil; and not containing a wax when the component (A) comprises only an ester-terminated polyamide resin.

Abstract: Sheet tobacco according to the present invention includes a carrier sheet made of nonwoven plant fibers, and a tobacco powder layer formed on the carrier sheet and containing a powder mixture of tobacco lamina powder and binder powder. In a sheet tobacco manufacturing process according to the present invention, a carrier sheet of plant fibers is formed by a nonwoven fabric production process, a tobacco powder layer is formed by spreading the powder mixture on the carrier sheet, and a cover sheet of plant fibers is optionally formed on the tobacco powder layer. Subsequently, the carrier sheet, the tobacco powder layer and the optical cover sheet are all together subjected to heating and pressing, thereby producing sheet tobacco with a two- or three-layer structure. The present invention also provides a manufacturing system for carrying out the sheet tobacco manufacturing process.
