Description

  The present invention relates to a nail cosmetic.

Conventionally, nitrocellulose is often used as a film forming agent in nail cosmetics, but when removing nail cosmetics containing nitrocellulose, an enamel remover mainly composed of acetone is used. There is a need. However, the enamel remover mainly composed of acetone has a risk of flammability during use, and may cause adverse effects on the nail itself, such as missing nails or becoming two nails when used continuously. There was a problem.
Accordingly, nail cosmetics that can be removed by other than enamel removers mainly composed of acetone have been proposed. For example, by using a vinyl acetate / vinyl pyrrolidone copolymer, a nail polish that can be removed with water (see Patent Document 1), or by using a specific triglyceride, the coating film can be removed without using a remover. A water-based beautiful nail material (see Patent Document 2) that can be used has been proposed.

JP-A-9-95423 JP 2001-31527 A

  However, in the technique of Patent Document 1 using a vinyl acetate / vinyl pyrrolidone copolymer, since it can be removed with water, there is a high possibility that it will fall off in daily life such as hand washing, and a satisfactory makeup life Was not obtained. Moreover, since water and ethanol were used as a solvent, a satisfactory drying rate was not obtained. On the other hand, in the technique of Patent Document 2 using a specific triglyceride, there is a high possibility that the makeup film peels off when the nail is hit or caught on a hard object, and a satisfactory makeup life cannot be obtained.

  Therefore, the conventional technology embodies a nail cosmetic that can be removed with anything other than an enamel remover mainly composed of acetone, can maintain a cosmetic film in daily life, and has an excellent drying speed. Was difficult.

  As a result of earnest research in view of the above circumstances, the present inventor has a dextrin fatty acid ester having a specific structure in an amount of 5 to 80% by mass, so that it has an excellent drying speed and is other than an enamel remover mainly composed of acetone. It has been found that a nail cosmetic having an excellent makeup can be obtained, and the present invention has been completed.

  That is, the present invention is an esterified product of component (A) dextrin and a fatty acid, wherein the dextrin has an average polymerization degree of glucose of 3 to 150, and the fatty acid is one or two branched saturated fatty acids having 4 to 26 carbon atoms. More than 50 mol% and 100 mol% or less of seeds or more with respect to all fatty acids, and linear saturated fatty acids having 2 to 22 carbon atoms, linear or branched unsaturated fatty acids having 6 to 30 carbon atoms, and 6 to 30 carbon atoms One or more selected from the group consisting of cyclic saturated or unsaturated fatty acids is contained in an amount of 0 mol% to less than 50 mol% based on the total fatty acids, and the degree of substitution of fatty acids per glucose unit is 1.0 to 3. A nail cosmetic containing 5 to 80% by mass of dextrin fatty acid ester which is 0 is provided.

  The nail cosmetic as described above, wherein the branched saturated fatty acid constituting the dextrin fatty acid ester of the component (A) is one or more selected from branched saturated fatty acids having 12 to 22 carbon atoms. is there.

  The dextrin fatty acid ester of the component (A) provides the nail cosmetic as described above, wherein the liquid paraffin having a kinematic viscosity at 40 ° C. of 8 mm 2 / s according to ASTM D445 measurement method does not gel.

  Furthermore, the cosmetics for nail | claw of the said description containing volatile hydrocarbon oil as a component (B) are provided.

  The nail cosmetic as described above, wherein the component (B) is a volatile hydrocarbon oil having 7 to 12 carbon atoms.

  The nail cosmetic described in the above, wherein the nail cosmetic is solvent-based.

  The nail cosmetic can be removed with ethanol, and the nail cosmetic described above is provided.

  The nail cosmetic of the present invention is excellent in drying speed, and can be removed by anything other than an enamel remover mainly composed of acetone, and is excellent in long-lasting makeup.

  Details of the present invention will be described below. In the present specification, “to” means a range including numerical values before and after.

  The component (A) dextrin fatty acid ester used in the present invention is an esterified product of dextrin and fatty acid, and the average polymerization degree of glucose of dextrin is 3 to 150, and the fatty acid has 4 carbon atoms relative to the total fatty acid. A novel substance having a substitution degree of fatty acid per glucose unit containing more than 50 mol% of 26 saturated saturated fatty acids, and capable of forming a film when applied. . (Hereafter, it may be simply referred to as “dextrin fatty acid ester”.)

The component (A) dextrin fatty acid ester used in the present invention has the following characteristics.
(1) When dextrin fatty acid ester is mixed with non-volatile liquid oil, the liquid oil does not gel.
“Liquid oil does not gel” means that when liquid paraffin having a kinematic viscosity of 8 mm 2 / s at 40 ° C. according to ASTM D445 measurement method is used as a liquid oil, the dextrin fatty acid ester is 5% by mass (hereinafter, simply “%”). When the viscosity of the liquid paraffin contained is dissolved at 100 ° C. and measured at 25 ° C. after 24 hours, the viscosity is that of a Yamaco DIGITAL VISCOMATE viscometer VM-100A (vibration type) (manufactured by Yamaichi Electronics Co., Ltd.). It means that it is below the detection limit. In addition, when gelatinizing, it can confirm by detecting a viscosity.

(2) The film formed by the dextrin fatty acid ester has a specific range of adhesion (tackiness).
The “tackiness” is determined by applying the dextrin fatty acid ester to a support and bringing the other support into surface contact from a state where they are separated from each other, then retracting them and separating them. When expressed by the load change (maximum stress value) applied to the contact point until the film is formed, a light liquid isoparaffin solution containing 40% of the dextrin fatty acid ester is formed on a glass plate with a 400 μm-thick applicator and dried. Texture analyzer, for example, texture analyzer TA. Using XTplus (manufactured by Stable Micro Systems), a probe made of a 12.5 mm diameter cylindrical polyacetal resin (manufactured by Delrin (registered trademark) DuPont) was used as a probe, and a load of 100 g was applied after 10 seconds. The load change when separated at 5 mm / second, that is, the tackiness is 30 to 1,000 g.

  In the present invention, the dextrin used for the dextrin fatty acid ester is preferably a dextrin having a glucose average polymerization degree of 3 to 150, particularly 10 to 100. When the average degree of polymerization of glucose is 2 or less, the obtained dextrin fatty acid ester becomes wax-like and the solubility in an oil agent decreases. On the other hand, when the average degree of polymerization of glucose exceeds 150, there may be a problem that the temperature for dissolving the dextrin fatty acid ester in the oil becomes high or the solubility becomes poor. The sugar chain of dextrin may be linear, branched or cyclic.
