Abstract

PROBLEM TO BE SOLVED: To provide a cosmetic excellent in lightness in spreading, flexibility of a cosmetic film, a massive volume effect (separate volume effect), and a curling keeping effect.SOLUTION: A cosmetic includes following components (A) and (B): (A) a resin composition obtained from carnauba wax through fractionation and having a softening point of 55-80°C and an iodine number of 20-55; and (B) a solid oil.

Description

  The present invention relates to a cosmetic containing a specific resin composition obtained by fractionating carnauba wax and a solid oil. More specifically, the present invention relates to a cosmetic film that is lightly spread and flexible, and further has eyelashes and eyebrows. When applied to keratin fibers such as hair, the present invention relates to a cosmetic excellent in volumetric volume effect and curl keeping effect.

  Conventionally, waxes and oil-soluble resins have been used to impart volume effect and curl effect in cosmetics for hair and hair cosmetics. For example, a mascara in which the curling effect is improved by blending an emulsion made of a specific high melting point wax and a film-forming polymer is disclosed (Patent Document 1). However, in recent years, vaginal cosmetics have been demanded to have both a natural feeling of use and finish without a sense of burden, and its sustainability (long-lasting makeup). In other words, the spread at the time of application is light, and each eyelash is thick and dark, so that the volume effect with the natural natural feeling of cocoon can be obtained without reducing the number of cocoon appearance. The volume quality effect), the ability to form a flexible decorative film with a certain hardness and strength, and maintain the initial curl shape for a long time (curl keep effect) are important quality items. However, although the technique of Patent Document 1 can obtain the curl effect, the decorative film formed from the high-melting wax is hard and brittle, so that it has poor adhesion to wrinkles and a sufficient volumetric volume effect is obtained. The curl-keep effect was inferior.

  On the other hand, in order to obtain such a volumetric volume effect, a curl keeping effect, and the like, a technique combining a dextrin fatty acid ester, a pigment, a candelilla resin, and a 1,2-alkanediol has been proposed (Patent Document 2). According to this technology, the lightness of spreading at the time of application and a volume effect can be obtained. However, as the amount of the candelilla resin increases, the flexibility of the decorative film is impaired, and 1,2 -Since alkanediol is likely to cause makeup collapse when it becomes compatible with sweat or sebum, a sufficient curl-keep effect may not be obtained.

Japanese Patent No. 29898929 JP 2008-63259 A

  The present invention provides a cosmetic material that has a light stretch spread, can form a flexible decorative film while having a certain hardness and strength, and has an excellent volume effect (separate volume effect) and curl keeping effect. It is an object to do.

  Under such circumstances, the present inventor has conducted extensive research to solve the above problems, and as a result, by combining a specific resin composition obtained by fractionating carnauba wax with solid oil, the stretch spread is light. In addition, it has a certain degree of hardness and strength, and a flexible decorative film is formed. When applied to wrinkles and hair, it has excellent volume effect (separate volume effect) and curl keeping effect. The headline and the present invention were completed.

That is, the present invention includes the following components (A) and (B):
(A) A cosmetic obtained by fractionating from carnauba wax, containing a resin composition (B) solid oil having a softening point of 55 to 80 ° C. and an iodine value of 20 to 55.

  The cosmetic of the present invention is lightly spread and can form a highly flexible cosmetic film.For example, when applied to wrinkles, there is little stickiness while sticking, so it does not become a bundle, By attaching uniformly to each cocoon and thickening each one, the volume effect of natural finish can be obtained without reducing the number of cocoon appearance (volumetric volume effect). Furthermore, since this decorative film has a certain hardness and strength but also has flexibility, it has an excellent effect of maintaining the initial curl shape for a long time (curl keeping effect).

It is the DSC chart measured with the differential scanning calorimeter of the resin composition (a) of manufacture example 1, and a carnauba wax (b). 2 is a gas chromatogram of the resin composition (a) and carnauba wax (b) of Production Example 1.

  Hereinafter, the present invention will be described in detail.

  The cosmetic composition of the present invention is blended with a resin composition obtained by fractionation from component (A) carnauba wax and having a softening point of 55 to 80 ° C. and an iodine value of 20 to 55. This resin composition is mainly composed of a resin component extracted from carnauba wax, has excellent film formability, has hardness and flexibility, and can form a uniform and smooth coating film. Since the structure is easily broken, it is excellent in lightness of extension. In addition, it has excellent adhesion to the application target, but there is little stickiness, and there is no tendency for the stickiness to increase suddenly when drying like conventional resins. One piece can be thickened, and the volume effect with a feeling of hair is excellent. By combining this resin composition with the component (B) solid oil, the lightness of spreading that cannot be obtained with waxes such as carnauba wax and other resin components, the flexibility of the cosmetic film, and the volume effect (separate volume) Effect), a curl keep effect can be obtained.

  The resin composition of component (A) is obtained from carnauba wax by fractionation so that the softening point is 55 to 80 ° C. and the iodine value is 20 to 55, and the fractionation method is particularly limited. Although it is not a thing, the method of fractionating and extracting a carnauba wax with an organic solvent is used suitably, for example.

  As the organic solvent used for fractional extraction, one or more selected from the group consisting of alcohols, ethers, ketones, hydrocarbons, and aromatic hydrocarbons can be used. As the alcohols, methanol, ethanol, isopropanol, butanol, as ethers, diethyl ether, methyl ethyl ether, as ketones, acetone, methyl ethyl ketone, as hydrocarbons, n-pentane, n-hexane, n-heptane Examples of aromatic hydrocarbons include benzene, toluene, xylene, trimethylbenzene, and ethylbenzene, and one or more of these can be used. Among these, methanol, ethanol, isopropanol, butanol, diethyl ether, and methyl ethyl ether are suitably used in terms of simplifying fractional extraction, and it is preferable to use one or more of these in combination.

  The fractional extraction can be performed, for example, by immersing solid carnauba wax in the organic solvent. The usage-amount of an organic solvent is 3-4 mass times with respect to a carnauba wax, What is necessary is just to immerse at 30-60 degreeC, Preferably it is 40-50 degreeC for 4 to 8 hours, Preferably it is about 5 to 6 hours. After the extraction treatment in this way, the extract is separated using a normal solid-liquid separation means such as filtration. Since the resin component is dissolved in this extract, the organic solvent is distilled away from the component (A) containing a large amount of the resin component by using a conventional concentration / drying means such as vacuum distillation or heating distillation. A resin composition can be obtained.

  The resin composition of component (A) thus obtained has a softening point in the range of 55 to 80 ° C. and an iodine value in the range of 20 to 55, and preferably has a softening point of 60 to 78 ° C. The iodine value is 23 to 50, more preferably the softening point is 65 to 75 ° C., the iodine value is 25 to 50, and particularly preferably the iodine value is 30 to 45. The resin concentration is preferably 15 to 40% by mass (hereinafter simply indicated as “%”), more preferably 25 to 35%, and particularly preferably 20 to 35%. As described above, since the resin concentration of carnauba wax is generally about 5%, this resin composition has a resin concentration about 3 to 8 times higher than that of carnauba wax. The resin composition in this range is excellent in film formability, has hardness and flexibility, can form a uniform and smooth coating film, has high adhesion but has little stickiness, and adheres well to the application target. It is excellent. When the resin concentration is less than 15%, it may be impossible to form a uniform and smooth coating film, and when it exceeds 40%, the stickiness becomes high and the decorative film may be uncomfortable. Further, when the softening point is 55 to 80 ° C., it is easy to handle and has film formability, and the formed film can have flexibility. In particular, cosmetics are easy to use in the production process, and have both film-forming properties and flexibility when applied to skin, hair, eyelashes, eyebrows, and the like. Further, the iodine value of 20 to 55 means that the saturated ester compound is reduced and the resin content remains from the carnauba wax which is the starting material. In addition, the difference in physical properties between the resin composition of component (A) and carnauba wax is shown in Table 1 below. Carnauba wax has a DSC endothermic peak in the vicinity of 82 ° C., whereas the resin composition of component (A) has a characteristic that such endothermic peak disappears and is not recognized. Furthermore, when this resin composition is analyzed by gas chromatography, a peak derived from the resin component is detected in the vicinity of a retention time of 2 to 10 minutes, but such a peak is not observed in carnauba wax. Moreover, in the case of carnauba wax, a peak of an ester wax having 56 carbon atoms appears around 20 to 30 minutes, but in this resin composition, it is recognized that the peak intensity is reduced. In the present specification, the resin concentration, melting point, softening point, acid value, saponification value, and iodine value are values according to the following measuring methods. Moreover, the conditions of DSC and gas chromatography are based on the conditions described in the production examples.

(Acid value)
The acid value was measured by the first method of acid value measurement described in the General Test Method for Outer Law. However, the sample amount was 3 g, and the solvent was titrated in warm using 30 ml of xylene and 50 ml of ethanol.
(Iodine number)
It was measured by the iodine value measuring method described in the General Test Method of the Sotohara. However, 30 ml of cyclohexane was dissolved in the solvent, and when the sample was difficult to dissolve, the amount of cyclohexane was appropriately added.
(Saponification value)
The saponification value was measured by the saponification value measuring method described in the general test method of the outer field regulations.
