Description

  The present invention relates to a specific resin composition obtained by separation from carnauba wax, and a cosmetic containing liquid oil and powder. More specifically, the present invention relates to a non-sticky, smoothly extending and adhering feeling to the skin. The present invention relates to a cosmetic that can form an excellent and uniform cosmetic film and has excellent sustainability.

  Conventionally, in cosmetics, various ingenuity has been made in order to improve the feeling of use, adhesion, and makeup sustainability. For example, it is known to blend a highly viscous oil such as polybutene in order to give a feeling of adhesion. However, when polybutene is blended, the sticky feeling and the spread of the spread are adversely affected on the feeling of use, and a sufficient makeup sustainability cannot be obtained. On the other hand, a method for reducing the poor feeling of use with silicone oil is also known, but there is a problem that the adhesion feeling is impaired by the blending of silicone oil. Furthermore, there is a method of blending powder to suppress stickiness, but there are cases where smooth stretch spread, uniformity and makeup sustainability are lacking.

  Various techniques for improving functions such as the feeling of use, adhesion, and makeup sustainability by combining specific waxes and resins have been proposed. For example, a combination of hydrocarbon wax containing isoparaffin and polybutene improves the feel and makeup sustainability and reduces stickiness (Patent Document 1), and organic silicone resin, volatile silicone oil, and powder By improving the makeup sustainability (Patent Document 2), a hydrocarbon resin and a liquid oil containing a volatile oil agent, an oil gelling agent and / or a solid oil, the feeling of use and the makeup sustainability A cosmetic (Patent Document 3) and the like with improved quality are disclosed.

  However, cosmetics using a combination of a hydrocarbon wax containing isoparaffin and polybutene improve the feel and non-stickiness, but have not been sufficient in terms of makeup sustainability. Moreover, the cosmetics using the organic silicone resin, the volatile silicone oil, and the powder in combination are inferior in terms of adhesion to the skin. Further, even a mixture of a hydrocarbon-based resin and a liquid oil containing a volatile oil agent, an oil gelling agent and / or a solid oil could not provide sufficient adhesion. As described above, the non-stickiness and the adhesion to the skin or the makeup persistence are basically contradictory properties, and it has been difficult for the conventional techniques to achieve both.

  The present invention provides a cosmetic material that has both a feeling of use that does not stickiness and spreads smoothly, an excellent feeling of adhesion to the skin, and makeup sustainability, and that can form a uniform cosmetic film to produce an excellent cosmetic effect. The issue is to provide.

  In such a situation, the present inventors have conducted extensive research to solve the above problems, and as a result, by combining a specific resin composition obtained by fractionating carnauba wax with liquid oil and powder, There is no problem, and it is possible to obtain a cosmetic that can produce a superior cosmetic effect by forming a uniform cosmetic film, as well as providing an excellent feeling of use that spreads smoothly and with excellent adhesion to the skin and makeup sustainability. As a result, the present invention has been completed.

That is, the present invention includes the following components (a) to (c):
(A) A cosmetic composition obtained by fractionating from carnauba wax, containing a resin composition having a softening point of 55 to 80 ° C. and an iodine value of 25 to 50 (b) liquid oil (c) It is.

  The cosmetic of the present invention has no stickiness, spreads smoothly, has excellent adhesion to the skin and makeup sustainability, and can form a uniform cosmetic film to produce an excellent cosmetic effect. is there.

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, having a softening point of 55 to 80 ° C. and an iodine value of 25 to 50. 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. Because of its low stickiness, it has excellent adhesion to the application target and good usability. By combining this resin composition with the components (b) and (c) described later, a smooth feeling of use is obtained as compared with the case where known waxes are used, and when a known resin is used. In comparison, it is non-sticky and has excellent adhesion to the skin, and can form a uniform makeup film to improve makeup sustainability.

  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 25 to 50, 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 off by using a normal concentration / drying means such as vacuum distillation or heating distillation, so that the component (a) containing a large amount of the resin component can be obtained. A resin composition can be obtained.

  The resin composition of the component (a) thus obtained has a softening point of 55 to 80 ° C. and an iodine value of 25 to 50, preferably a softening point of 65 to 75 ° C. The iodine value is 30-45. Further, the resin concentration is preferably 15 to 40% by mass (hereinafter simply indicated by “%”), more preferably 25 to 35%. As described above, since the resin concentration of carnauba wax is generally about 5%, the resin composition of component (a) 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. If the resin concentration is less than 15%, it is impossible to form a uniform and smooth coating film, and if it exceeds 40%, the stickiness becomes high and the decorative film is 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 even when applied to skin, hair, and the like. An iodine value of 25 to 50 means that a saturated ester compound is reduced and a resin component remains from carnauba wax which is a starting material. Other differences in physical properties between the resin composition of component (a) and carnauba wax are 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 feature that such endothermic peak disappears and is not recognized. Furthermore, when the resin composition of component (a) 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 invention, 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 examples.

The resin amount (%) of the resin composition was determined from the resin concentration of carnauba wax as the residue concentrated by filtration by the above fractional extraction.
(Melting point)
It measured by DSC by the conditions as described in an Example.
(Softening point)
It was measured by the softening point measurement method described in the General Test Method for Outer Standards. However, the measurement was performed at a sample amount of 0.5 g, a steel ball having a diameter of 12 mm and a weight of 10 g and a heating rate of 1 ° C. per 5 minutes.
(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.

  This resin composition corresponds to the INCI name Coppericer Cerifera (Carnauba) Wax Extract and can be displayed as a carnauba wax extract.

  As is apparent from the results in Table 4, the oily eye color cosmetics of Examples 7 to 9 of the present invention are not sticky, have a good spread, and have excellent adhesion to the skin, compared with Comparative Examples 6 to 9. The makeup persistence and the uniformity of the makeup film were also high. On the other hand, in Comparative Example 6 in which the component (a) was not blended, the adhesion at the time of application was lacking, it was difficult to uniformly spread, and the adhesion to the skin and the uniformity of the cosmetic film were inferior. Further, in Comparative Example 2 in which hydrogenated pentaerythrityl rosin acid, which is a resin having a high adhesion feeling, was used instead of the component (a), it was sticky and hardly spread on the eyelid. Furthermore, in Comparative Example 3 in which trimethylsiloxysilicic acid, which is a less sticky resin, was used in place of component (a), the spread of spread was good, but the adhesion to the skin and the makeup persistence were inferior. Further, in Comparative Example 4 in which carnauba wax, which is a wax with little stickiness, was used instead of component (a), it was not smooth and was likely to be uneven, and a uniform decorative film could not be obtained.
