Description

  The present invention relates to an oil-in-water cosmetic composition containing a fragrance-containing microcapsule.

Conventionally, microcapsules containing a perfume are widely used in laundry detergents and deodorants, and effects such as sustained release of a desirable smell have been expected (Patent Documents 1 and 2). The microcapsules can be prepared by chemical methods such as condensation polymerization, physicochemical methods such as coacervation method, liquid drying method, melting dispersion cooling method, and pan coating method, air suspension method, spray drying method There are mechanical methods such as
As a chemical method by condensation polymerization, manufacture is made of microcapsules using a melamine resin made from melamine as a raw material (Patent Document 1), a polyurethane resin made from polyfunctional isocyanate as a raw material, a polyurea resin (Patent Document 3), etc. as a film wall The method has been reported.
On the other hand, a method has been reported in which microcapsules can be produced in a novel composite coacervation system that does not use gelatin by mixing and phase separating an aqueous solution of a specific cellulose and an aqueous solution of a specific copolymer. (Patent Document 4).
Furthermore, in the capsule prepared by the coacervation method, the core containing the flavor and / or fragrance material from the shell is obtained by containing the fat component containing the hydrogenated oil or the hydrogenated fat or the cocoa butter or a mixture thereof in the core. A method for suppressing leakage is also reported (Patent Document 5).

  Consumers are required to maintain the fragrance as a cosmetic. However, when the thing which contains the fragrance | flavor in the microcapsule which uses the melamine resin of patent document 1 as a film wall is used for cosmetics, there existed a case where the persistence of a fragrance was scarce. In addition, when a perfume is contained in a coacervated capsule containing a hydrogenated oil or a hydrogenated fat or cocoa butter or a mixture thereof as shown in Patent Document 5, the persistence of the scent is poor, and the capsule is The stability over time may be bad.

  Therefore, the object of the present invention is to obtain a cosmetic composition having good stability over time, intensity of smell when coming into contact with a cosmetic film after a long time since application, and no stickiness at the time of use. I assume.

The present inventors attempted to maintain the fragrance for a long time after application of the cosmetic by incorporating the flavor into the microcapsule when blending the flavor into the cosmetic. Furthermore, as a method that can realize the aroma strongly after a long time, the present inventors cause the capsule to disintegrate by contacting the cosmetic film after a long time after applying the preparation with a hand or a finger. And explored new methods to induce the occurrence of aroma.
Using the melamine resin of Patent Document 1 or the polyurea resin of Patent Document 3 containing microcapsules in microcapsules having a film wall as a cosmetic, and applying the cosmetic on a cosmetic film after a long time has passed. Even when touching with a hand or a finger, the capsule is physically difficult to disintegrate because the membrane wall of the microcapsule is strong, and it is difficult to induce the generation of a scent. In addition, cosmetics containing a perfume are contained in a coacervated capsule containing hydrogenated oil or hydrogenated fat or cocoa butter or a mixture thereof as shown in Patent Document 5, and then the cosmetic is applied. Even when touching the cosmetic film after a long time has passed with a hand or a finger, the generation of the scent is insufficient.

  Therefore, as a result of intensive investigations, the present inventors have studied emulsion droplets containing an oil agent having a water absorption capacity of 100% or more, and microcapsules containing an anionic polymer, a monovalent metal salt, a polyvalent metal salt, and a perfume. It has been found that the composition for an oil-in-water type cosmetic composition containing the above-mentioned composition is excellent in the intensity of the aroma when coming into contact with the cosmetic film after a long time since application. Furthermore, the above-mentioned oil-in-water cosmetic composition was also found to be excellent in stability over time, and not sticky at the time of use.

In the present invention, the oil holding capacity of the oil agent is specifically evaluated as follows. That is, 10 g of a sample (oil solution) heated to 50 ° C. is weighed into a 200 mL beaker. While stirring at 3000 rpm with a disper mixer, water at 50 ° C. is slowly added until water is drained from the sample. Measure the addition amount (mass) of water until drainage of water from the sample starts. The added amount is divided by the mass of 10 g of the sample to obtain a quotient.

Comparative Example 1 which does not contain the components (B1) to (B4), and Comparative Example 2 which does not form microcapsules of those containing the components (B1) to (B4), the amount of the perfume in the composition is an example Same as 1 to 12, but differs from Examples 1 to 12 in that the flavor is not contained in the microcapsule. Since the perfume has high volatility, the emulsions of Comparative Examples 1 and 2 have 24 hours after application whether the intensity of the scent does not change at all before and after touching the cosmetic film (“1 point: the intensity of the odor is Very weak)), the intensity of the scent is weak even when touching the cosmetic film ("2 points: the intensity of the aroma is weak"), it is performed in the intensity of the scent when it comes in contact with the cosmetic film after a long time It was inferior to Examples 1-12 ("x: 2 points or less: inferiority").
In Comparative Example 3 which does not contain the component (A), 24 hours after application, was the intensity of the scent weak even after touching the cosmetic film ("2 points: the intensity of the aroma is weak") or touching the cosmetic film Also, the intensity of the scent is not good ("3 points: the intensity of the scent is normal"), and the intensity of the scent when it comes in contact with the cosmetic film after a long time has passed since the application It was inferior to "(": 3 points or more exceeding 2 points: Somewhat bad "). Moreover, it was inferior to Examples 1-12 also in non-stickiness at the time of use ("(triangle | delta): 3 points or more exceeding 2 points | pieces: Somewhat defect").
Comparative Example 4 in which the component (A) was contained in the microcapsules and not contained in the emulsion droplets was inferior to the examples 1 to 12 in the temporal stability ("x: poor texture within 2 weeks , Aggregates are observed: "bad"). In addition, in the emulsion of Comparative Example 4, 24 hours after application, the intensity of the scent does not change at all before and after touching the cosmetic film ("1 point: the intensity of the aroma is very weak"), or The intensity of the aroma is weak even when touched ("2 points: the intensity of the aroma is weak"), and inferior in the intensity of the aroma when contacted with the cosmetic film after a long period of time since application. ("X: 2 points or less: bad"). From this, it was suggested that the component (A) needs to be contained in the emulsion droplet.
