Description

TECHNICAL FIELD The present invention relates to a water-in-oil emulsified cosmetic. More particularly, it relates to a powder-containing water-in-oil emulsified cosmetic.

In recent years, the demand for functional cosmetics has increased in the market, and foundations and sunscreens that protect the skin from UVA (long wavelength ultraviolet rays with a wavelength of 320 to 400 nm) and UVB (middle wavelength ultraviolet rays with a wavelength of 290 to 320 nm) are used. Cosmetics and the like having a high UV protection effect have been put on the market.
UV absorbers and UV scattering agents are blended to obtain a high UV protection effect, but there is concern that oil-soluble UV absorbers may feel sticky to the touch, and UV scattering agents are excellent in safety. However, when used in a large amount, it gives a strong feeling of dryness, and the problem is that the finish becomes unnatural.
In water-in-oil emulsified cosmetics, which are often used in foundations and sunscreens, an oil-soluble UV absorber is blended in the internal phase (aqueous phase) in consideration of the above-mentioned problems with oil-soluble UV absorbers and UV scattering agents. There is known a technique for enhancing the UV protection ability by using a compound (see, for example, Patent Literature 1). In addition, in order to increase the UV protection power without adding an excessive amount of the UV absorber, a technique using a porous spherical powder having a specific average particle size and oil absorption has been proposed (for example, Patent Document 2).

Japanese Unexamined Patent Application Publication No. 2011-236201 Japanese Patent Application Laid-Open No. 2020-90468

However, when the UV absorber is blended in an oil system, it is resistant to sebum, and as in the technology of Patent Document 1, when it is blended in a water system, it has low resistance to sweat and water, and the durability of the UV protection effect is still insufficient. I didn't. Furthermore, in the technique of increasing the UV protection power by using a porous spherical powder, such as the technique of Patent Document 2, the high liquid absorption and the feeling of use of the powder itself cause a dry feeling and deteriorate the uniformity of the cosmetic film. In addition, since it is a water-type or oil-in-water type cosmetic, it has not been possible to cope with the deterioration of the UV protection effect due to sweat and water.
Therefore, we have developed a water-in-oil emulsified cosmetic that has a high UV protection effect, a moisturizing feeling without stickiness, a uniform cosmetic film, and does not lose its makeup lasting effect against sweat, water, and even sebum. was desired.

Therefore, the present invention provides a water-in-oil emulsion that has a high UV protection effect, a moisturizing feeling without stickiness, a uniform cosmetic film, and a long-lasting cosmetic effect against sweat, water, and even sebum. The purpose is to provide cosmetics.

In view of the above-mentioned circumstances, the present inventors have conducted intensive research and found that an aqueous dispersion of an acidic heteropolysaccharide and an organic ultraviolet absorber, a metal oxide having an ultraviolet protection effect, and a specific particle size and liquid absorption amount The inventors have found that the above problems can be solved by combining powders. In addition to the effect of improving the dispersibility of the water-dispersible organic UV-grade agent due to the charge of the acidic heteropolysaccharide and the improvement of the water resistance due to the film-forming property, the dryness of the skin due to the metal oxide and the powder with high liquid absorption.

D.C was defoamed to obtain a water-in-oil emulsion foundation.

(Evaluation method)
<Method for measuring UV protection effect>
2 mg/cm ² of the cosmetic was applied to a polymethyl methacrylate plate for measurement, and after drying for 10 minutes, the SPF value was measured three times with an SPF analyzer (UV-2000S, manufactured by Labsphere) to obtain the average SPF value. rice field.

<Water resistance test method for UV protection effect (difficulty in removing makeup lasting effect against sweat and water)
2 mg/cm ² of foundation was applied to a polymethyl methacrylate plate for measurement, dried for 10 minutes, and then fixed at a height of 10 cm on the side of a tub-shaped water tank container having a diameter of 50 cm and a depth of 15 cm. Water was poured into the basin to a depth of 11 cm, and the vessel was rotated so that the water flow in front of the polymethyl methacrylate plate was 12-14 cm/s and the rotation speed of the water tank container was 20 rpm. After 80 minutes, the sample was taken out, dried for 2 hours or longer, and then measured for SPF 3 times with an SPF analyzer (UV-2000S, manufactured by Labsphere) to obtain an average SPF value. This value was divided by the SPF value measured without conducting the water resistance test, and the value obtained by multiplying the value by 100 was evaluated as the water resistance effect according to the following criteria.

A: More than 90% B: More than 80%, 90% or less C: More than 70%, 80% or less D: 70% or less grass)>
2 mg/cm ² of foundation is applied to a polymethyl methacrylate plate for measurement, and after drying for 10 minutes, 5 ml of a mixed oil of olive oil: oleic acid: squalane = 5: 3: 2 is evenly dropped onto the sample as a simulated sebum. . After standing for 5 minutes, a tissue paper was placed on the sample so as not to rub it, and excess oil was absorbed, and the SPF value was measured 3 times with an SPF analyzer (Labsphere, UV-2000S) to obtain an average SPF value. . This value was divided by the SPF value measured without conducting the sebum resistance test, and the value obtained by multiplying the value by 100 was evaluated as the sebum resistance effect according to the following criteria.

(Evaluation criteria): (Evaluation results)
A: More than 80% B: More than 60% and 80% or less C: More than 40% and 60% or less D: 40% or less <sensory evaluation>
For the water-in-oil type emulsified foundation, 20 cosmetic evaluation specialist panels took an appropriate amount and spread it on the skin with fingers to use it. For each sample, the average value was calculated from the total score of all the panelists, and the evaluation was made according to the following criteria.

(Evaluation item) : (Evaluation criteria)
Moisturizing feeling: Whether the skin feels moisturized without dryness during and after application. Non-stickiness during application: Whether the skin feels sticky during application. please ~

(Evaluation criteria)
(Rating): (Evaluation result):

It was a medium water type emulsified foundation. On the other hand, Comparative Example 1 that does not contain component (a), Comparative Example 2 that contains locust bean gum instead of component (a), and Comparative Example 3 that contains carbomer instead of component (a) have UV protection effects. The durability and uniformity of the cosmetic film were remarkably inferior. Comparative Example 4, which did not contain component (b), and Comparative Example 5, which contained phenylbenzimidazole sulfonic acid instead of component (b), exhibited durability of the UV protection effect, no stickiness during application, and uniformity of the cosmetic film. It was remarkably inferior in quality. Comparative Example 6 containing no component (d), Comparative Examples 7 to 9 containing silica with different particle sizes or oil absorption instead of component (d), and containing acrylates crosspolymer instead of component (d) Comparative Example 10 was inferior in the durability of the UV protection effect, lack of stickiness during application, and uniformity of the cosmetic film.
