Description

Technical Field

[0001] The present invention relates to an oil-in-water type sunscreen cosmetic, and more particularly, to an oil-in-water type sunscreen cosmetic that contains specific components and has particularly excellent secondary adhesion resistance effect and makeup texture, and in addition, has no dryness, squeakiness or stickiness, and does not cause stability problems such as aggregation and precipitation.

Background Art

[0002] Protecting the skin from the harm of ultraviolet rays is one of the important issues for skin care and body care. Sunscreen cosmetics aim to defend against ultraviolet rays and minimize their adverse effects on the skin. Generally, in sunscreen cosmetics, an ultraviolet absorber and an ultraviolet scattering agent are combined to impart a high ultraviolet ray protection effect (Non-Patent Document 1).

[0003] As the dosage form of sunscreen cosmetics, an oil-in-water type or water-in-oil type emulsified dosage form is used. In recent years, the demand for sunscreen preparations with a fresh feeling of use that can be used with a skin care feeling while having a high SPF (Sun Protection Factor) value has been increasing, and oil-in-water type sunscreen preparations are particularly widely used.

[0004] However, compared with water-in-oil type emulsified cosmetics, the coating film of oil-in-water type emulsified cosmetics tends to be uneven, and the resistance of the film is also inferior. Therefore, when aiming for a high SPF value, it is necessary to highly formulate a larger amount of ultraviolet absorber and ultraviolet scattering agent. High formulation of these may lead to skin irritation, deterioration of the feeling of use such as squeakiness and stickiness, and problems may occur (Patent Document 1).

[0005] Furthermore, in an oil-in-water type emulsified cosmetic having a lower oil content than a water-in-oil type emulsified cosmetic, when a large amount of ultraviolet absorber and ultraviolet scattering agent are formulated, not only is it difficult to maintain the emulsion stability, but also problems such as precipitation of the ultraviolet absorber and aggregation of the ultraviolet scattering agent over time, which are likely to cause stability problems, occur.

[0006] Most ultraviolet absorbers are generally poorly soluble in water, and it is necessary to consider dissolution stability in order to incorporate them at high concentrations into formulations. To enhance dissolution stability, it is known to use highly polar oils with good solubility for the ultraviolet absorber. For example, diisopropyl sebacate is used, but to incorporate these highly polar oils at high concentrations into water-in-oil emulsions, a large amount of surfactant must be added, resulting in problems with the feel of use such as stickiness and greasiness.

[0007] In addition, to impart a high ultraviolet protection effect, it is also necessary to incorporate an ultraviolet scattering agent. Generally, metal oxides such as titanium oxide, zinc oxide, iron oxide, and cerium oxide are used as ultraviolet scattering agents. To stabilize the formulation by incorporating these ultraviolet scattering agents, it is necessary to incorporate an oil with good dispersibility or a dispersant. However, if an oil that inhibits the solubility of the ultraviolet absorber is incorporated, poor stability such as precipitation occurs when used in combination with the ultraviolet absorber. Therefore, a material that can achieve both dispersion stability and dissolution stability must be selected. For example, diisopropyl sebacate described above is a solvent with excellent solubility for the ultraviolet absorber, but the results regarding the dispersibility of the ultraviolet scattering agent were not satisfactory. When the dispersion of the ultraviolet scattering agent deteriorates, not only does the formulation stability deteriorate, but the feeling of roughness and stickiness also deteriorates, so achieving both is essential.

[0008] As a conventional technique, for example, a technique for stably dispersing an ultraviolet scattering agent in an oil phase by using a volatile hydrocarbon or isostearic acid has been reported (Patent Document 2). However, since many of the ultraviolet absorbers used are liquid components and poorly soluble ultraviolet absorbers are not incorporated, it cannot be said that both the aggregation stability of the ultraviolet absorber and the dispersion stability of the ultraviolet scattering agent are achieved.

[0009] Cosmetic texture refers to a term that indicates whether makeup products adhere well to the skin. Good cosmetic texture means that makeup products can be evenly applied to the skin without unevenness and the finished skin looks nice. Generally, a long-lasting makeup effect may be imparted as an effect of a makeup base (Patent Document 3), but the long-lasting makeup effect is a technology related to makeup persistence and relates to functions such as being resistant to sweat and sebum. The cosmetic texture effect of the present application refers not to an effect related to persistence but to the finish of makeup products that can be immediately felt and the effect of being able to be evenly applied without unevenness. In recent years, due to the increasing beauty awareness of consumers, the demand for cosmetics with excellent cosmetic texture has been increasing. In addition, due to consumers' awareness of saving time and the expanding demand for sunscreen effects, the need to use sunscreen as a substitute for a makeup base has also been increasing. Therefore, in recent years, there has been a demand for the development of products with excellent cosmetic texture effects even in sunscreen cosmetics.

[0010] As a technology for imparting a cosmetic texture effect, generally, there are many formulation technologies for improving rough skin. For example, as a result of using a formulation in which 1-acyl-2,3-cyclic phosphatidic acid or a salt thereof, which is a component for suppressing skin aging phenomena, and polyoxyethylene methyl glucoside having a specific average addition molar number of ethylene oxide are combined at a specific ratio for one week, a result showing an improvement effect on cosmetic texture has been obtained (Patent Document 4). Furthermore, an emulsion composition in which polymers are combined at a specific mass ratio, wherein one or more compounds selected from sphingosine, a salt of sphingosine, pseudo-sphingosine, a salt of pseudo-sphingosine, an anionic surfactant, and a cationic surfactant, ceramides, glycerin fatty acid esters, higher alcohols, and cetyl alcohol, when mixed at 85°C with 25 parts by mass with respect to 100 parts by mass and then measured at 25°C, has a light transmittance of 90% or more and a glass transition temperature Tg of the main chain of 25°C or less, has been reported to improve cosmetic texture when used continuously for 3 days and makeup is applied after washing the continuously used area. (Patent Document 5). However, none of them can immediately improve the makeup texture effect, and it takes time to improve the makeup texture. Since the makeup base is required to allow the makeup cosmetics to be beautifully finished immediately after application, the improvement of the makeup texture effect was not a satisfactory effect.

[0011] As an example of improving the makeup texture effect with a sunscreen cosmetic, there has been developed a combination of 1 to 13% by mass of microcapsules of polysilicon with an average particle size of 0.1 to 10 μm encapsulating an ultraviolet absorber, 0.5 to 10% by mass of a compound represented by formula (I), and 0.1 to 1% by mass of carboxyvinyl polymer or alkyl-modified carboxyvinyl polymer (Patent Document 6). However, the makeup texture effect is not sufficient, and furthermore, since it is not used in combination with an ultraviolet scattering agent, the ultraviolet protection effect is also not satisfactory.

[0012] In recent years, from the perspectives of the background of mask wearing and the sustainability of the sunscreen effect, a secondary adhesion resistance effect to clothing, etc. has been demanded (Patent Document 7). Secondary adhesion means that the applied sunscreen re-adheres to clothing, belongings, etc. If secondary adhesion occurs, the ultraviolet protection effect and the finish of the makeup film may deteriorate, and in recent years, a secondary adhesion resistance effect has also been demanded for sunscreens. As a technique for enhancing the secondary adhesion resistance effect, there has been disclosed a technique of blending a large amount of components that evaporate at room temperature, such as volatile silicone oil, volatile hydrocarbon oil, volatile hydrofluoroether, and water, to impart quick-drying properties, and a technique of combining an oil-based film-forming agent such as a silicone-based resin having no hard transferability (Patent Documents 8 and 9). However, Patent Documents 8 and 9 are techniques related to water-in-oil type cosmetics. When applying the techniques disclosed for oil-in-water type cosmetics, problems such as the imparting of a hard film property, a feeling of dryness, and a decrease in the moisturizing effect occur. In addition, a squeaky feeling and a sticky feeling peculiar to the film-forming agent also occur, so the feel of use is not sufficient either.

[0013] From the above, it has been an urgent task to develop an oil-in-water type sunscreen cosmetic that has an excellent secondary adhesion resistance effect and excellent makeup texture, and in addition, has no dry feeling, squeaking feeling or stickiness, and does not cause poor stability such as aggregation or precipitation.

[0028] Component (C), the ultraviolet scattering agent used in the present invention, is not particularly limited, and those usually used in cosmetics can be used, but hydrophobized metal oxides are preferably used. From the viewpoint of ultraviolet protection, it is preferable to use fine particles having an average primary particle diameter of 100 nm or less, which is measured for 10 particles in an arbitrary field of view using a scanning electron microscope. The average primary particle diameter in the present invention can be determined, for example, as the arithmetic mean of the major axis and the minor axis of the particles from the image analysis of a transmission electron microscope. Particularly preferable metal oxides include titanium oxide, zinc oxide, cerium oxide, and the like.

[0039] In addition to the above essential components, it is also possible to blend components generally used in cosmetics, etc. as required in the water-in-oil type sunscreen cosmetic of the present invention. For example, dispersants other than component B, powders other than component C, pearl agents, moisturizers, water-soluble polymers, fragrances, bactericides, preservatives, antioxidants, pH adjusters, chelating agents, anti-inflammatory agents, antioxidants, cooling agents, herbal extracts, vitamins and other additives can be appropriately blended in a timely manner. The blending ratio when containing these components can be appropriately selected according to their types and purposes, and one type can be used alone, or two or more types can be appropriately combined and used.

Examples

[0040] The present invention will be further described below with reference to examples. These examples do not limit the present invention in any way.

[0041] 〔Examples 1 to 14 and Comparative Examples 1 to 7〕 A sunscreen cosmetic was prepared from the components shown in Table 1 by a conventional method and evaluated by the following method. The results are shown in Table 1.

[0042] <Method for evaluating secondary adhesion resistance> Samples were prepared according to the SPF measurement method specified in ISO-24444. 2 mg / cm 2 of the composition was uniformly applied to a helioplate HD6 (HELIOPLATE (registered trademark) HD6, manufactured by HerioScreen Lab., plate size: 5 cm × 5 cm, material: PMMA), and the SPF value was measured using an SPF analyzer UV-2000S (manufactured by Sanyo Trading Co., Ltd.). Next, the plate on which the above sample preparation was performed was placed on a tissue paper with the coated surface facing down, and a 500 g load was placed on the plate for 10 minutes to adhere it to the tissue paper. Then, the tissue paper was peeled off and the SPF value was measured again. The percentage of the SPF value after peeling off the tissue paper relative to the original SPF value was calculated, and this value was taken as the residual rate (%).

[0053] [Table 1]

[0054] [Table 2]

[0055] According to the oil-in-water sunscreen cosmetic of the present invention (Examples 1 to 14), the secondary adhesion-free effect and makeup application were excellent, and in addition, there was no dry feeling, squeaky feeling, or sticky feeling, and good results were obtained in all aspects such as stability against aggregation and precipitation. In addition, it was confirmed that the makeup application was improved even when a different foundation was used. In Examples 13 to 14, component E was replaced with a similar component, but when component E was replaced, the secondary adhesion-free effect, makeup application, squeaky feeling, sticky feeling, and aggregation stability tended to be slightly inferior, so it was found that volatile hydrocarbons are more preferable for component E in order to achieve the object of the present application. In Comparative Examples 1 to 3, component A was not blended or was replaced with a similar component, but when component A was replaced, the makeup application, secondary adhesion-free effect, squeaky feeling, sticky feeling, dry feeling, and deposition stability tended to be significantly worse, and the object of the present application could not be achieved. In Comparative Examples 4 to 7, component B was not used or was replaced with a similar component, but when component B was replaced, the makeup adhesion and secondary adhesion resistance effect deteriorated, and there was a tendency for the feeling of squeaking, stickiness, dryness, and deposition stability to deteriorate. From the above results, it is possible to provide a new oil-in-water sunscreen cosmetic composition having the composition of the present application that can achieve all of the objects of the present application and that is endowed with functions that could not be achieved with conventional component compositions.

[0056] Sunscreen cosmetics of each formulation were prepared in a conventional manner. It was confirmed that the effects of the present invention were achieved in all formulations.
