Description

  The present invention relates to a solid powder cosmetic, and more specifically, it is possible to easily wash away even with a conventional face wash while removing makeup while having excellent cosmetic properties, and smooth extension and spreading. The present invention relates to a solid powder cosmetic which is also excellent in ease of removal to props and the like.

  A solid powder cosmetic such as eye color or powder foundation is a cosmetic obtained by filling and molding a cosmetic base obtained by adding and mixing an oil component to a powder component in a container such as a dish, and the method of use is simple. It is preferred by consumers because of its excellent portability. The quality required for solid powder cosmetics includes a variety of cosmetic properties, ease of use such as ease of blurring, and feeling of use such as no sense of burden, but in recent years, when it is desired to remove makeup, it can be easily washed away Good washability that can be done is also strongly demanded.

  In response to such customer needs, techniques using surface-treated powder have been proposed as techniques for improving the cleanability of the powder (see, for example, Patent Documents 1 and 2). However, in these techniques, there is a concern that the adhesion of the powder to the skin may deteriorate, so that the longevity of the makeup may deteriorate, or the powder may be rendered hydrophobic, which in turn may lower the washability with water. was there.

  On the other hand, techniques for improving cosmetic properties include techniques using surface-treated powders and solid and / or semi-solid oil agents (see Patent Document 3) and techniques using gelling agents such as swellable organically modified clay minerals (Patent Document 3) 4) has been proposed. However, with these techniques, although the feeling of adhesion to the skin and the moldability are good, the usability such as smooth extension and take-off for props is not satisfactory.

Unexamined-Japanese-Patent No. 2007-210903 JP, 2012-121835, A Unexamined-Japanese-Patent No. 2010-37213 JP, 2010-235513, A

  Therefore, in the prior art, it has been difficult to realize a solid powder cosmetic product which has both contradictory qualities of good washability and good cosmetic durability and has good usability. That is, the present invention is a solid powder which is excellent in long-lasting, but can be easily washed away with a normal face wash when removing makeup, and is also excellent in smooth elongation and spreading and removal to props etc. It is an issue to provide a cosmetic.

  In view of the above-mentioned situation, as a result of intensive research conducted by the present inventors, the present inventors have made cosmetics durable by combining a specific dextrin fatty acid ester having appropriate tackiness with a nonionic surfactant of HLB 10 to 15. The present invention has been accomplished by finding that a solid powder cosmetic composition is obtained which is excellent in water, but also excellent in water washability and smooth extension and spread, and is excellent in removal to props and the like.

The present invention relates to a solid powder cosmetic containing

  The solid powder cosmetic composition of the present invention is excellent in long-lasting, but can be easily washed away with a normal face wash when removing makeup, and it can be smoothly spread and spread to props etc. It is also excellent in the ease of taking.

Hereinafter, the present invention will be described in detail.
The dextrin fatty acid ester of the component (a) used in the solid powder cosmetic of the present invention is a component that enhances cosmetic longevity by forming a film having appropriate tackiness. It is an esterified product of dextrin and fatty acid, and the degree of substitution of fatty acid for dextrin is 1.0 to 3.0 per glucose unit, preferably 1.2 to 2.8. If the degree of substitution is less than 1.0, the solution temperature in liquid oil or the like is as high as 100 ° C. or higher, and coloring and unusual odor occur, which is not preferable.

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

(2) The film formed by the dextrin fatty acid ester of component (a) has a tackiness in a specific range.
“Tackiness” is obtained by applying the dextrin fatty acid ester to a support and bringing another support into contact with each other from the mutually separated state, then retracting and separating, and starting the retraction and completely separating. In the case of the load change (maximum stress value) applied to the contact point up to the end, a light fluid isoparaffin solution containing 40% by mass of the dextrin fatty acid ester is formed into a film 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), using a probe made of polyacetal resin 12.5 mm in diameter (made by Delrin (registered trademark) DuPont) as a probe, after applying a load of 100 g and holding for 10 seconds, 0. The load change when separated at 5 mm / sec, that is, the tackiness is 30 to 1,000 g.

  The dextrin used for the dextrin fatty acid ester of component (a) 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 waxy and the solubility in oil decreases. In addition, when the glucose average polymerization degree exceeds 150, problems such as an increase in the dissolution temperature of the dextrin fatty acid ester in the oil agent or a deterioration in the solubility may occur. The sugar chain of dextrin may be linear, branched or cyclic.

It can be prepared by converting it into a branched unsaturated aldehyde of the formula 18 and then hydrogenation and oxidation (hereinafter abbreviated as "aldol condensation type"), which is commercially available from, for example, Nissan Chemical Industries, Ltd. 2-Heptylundecanoic acid can be produced by dimerization of nonyl alcohol by the Guerbet reaction (also referred to as Guerbet reaction or Guerbet reaction) and oxidation, which is commercially available from, for example, Mitsubishi Chemical Corporation, and has a branched position As a slightly different similar mixture, it is commercially available from Nissan Chemical Industries, Ltd., and two methyl branched type in which the starting alcohol is not linear saturated is also commercially available from Nissan Chemical (hereinafter generally referred to as "gerbet reaction type"). ). In addition, methyl branched isostearic acid is obtained, for example, as a by-product of dimer production of oleic acid [see, for example, J. Am. Amer. Oil Chem.

As a fatty acid derivative used for the esterification reaction with the above-mentioned dextrin, for example, a halide of the above-mentioned fatty acid, an acid anhydride or the like is used.
In either of the cases (1) and (2), dextrin is first dispersed in a reaction solvent, and a catalyst is added as necessary. A halide of the above-mentioned fatty acid, an acid anhydride and the like are added to this and reacted.
