Description

  The present invention relates to a sunscreen cosmetic. More specifically, the present invention relates to a sunscreen cosmetic that contains an ultraviolet absorber and an alkaline-genes-producing polysaccharide and has excellent coating uniformity.

  Sunscreen cosmetics such as sun-care cosmetics that contain UV absorbers are applied to the skin by applying UV absorbers dissolved in an aqueous phase or oil phase to the skin to form a UV absorber film on the skin. Prevent UV exposure. Therefore, by making the water phase and oil phase components uniform on the skin, it is possible to draw out sufficient sunscreen cosmetic performance. However, due to the influence of the viscosity of the oil component, there has been a problem that in the coating operation, the coating start point is thicker and becomes a patch at the elongation end point. Furthermore, when the titanium oxide or zinc oxide surface-treated with lipophilicity or hydrophilicity is blended as an ultraviolet scattering agent, the uniformity of coating is further impaired because it becomes a mixed state of liquid and solid. Become. Moreover, when apply | coating to the skin in a dry state, the extensibility of sunscreen cosmetics falls.

  For this reason, a method for improving the coating uniformity has been adopted by blending a sunscreen cosmetic with a silicone oil having a low sliding friction, a polyhydric alcohol such as glycerin that improves skin familiarity, a surfactant, a polymer, etc. It was.

  Patent Document 1 discloses that a moisturizing agent containing polyaspartate and the use of the moisturizing agent have good usability when applied, give the skin and hair a firm and moist feeling, and are sticky, slimy. A method for obtaining a cosmetic without a feeling of tension is disclosed. Patent Document 2 includes a combination of trisbiphenyltriazine or an aqueous dispersion thereof, dimethicodimethylbenzalmalonate, 2-ethylhexyl paramethoxycinnamate, and hexyl diethylaminohydroxybenzoylbenzoate, which provides a good feeling of use and ultraviolet light. A method of providing a sunscreen composition that combines a protective effect is disclosed. However, these methods are insufficient for obtaining a coating uniformity and a good feeling of use in the case of a formulation in which an inorganic powder component such as titanium oxide or zinc oxide is blended.

  Also known is a method of suppressing the stickiness and squeaky feeling when blending powders such as titanium oxide and zinc oxide with good formulation stability, coating uniformity, fit on the skin, stretching and sticking. Patent Document 3 discloses that a polyoxyethylene alkyl or alkenyl ether having an alkyl group or an alkenyl group having 20 to 24 carbon atoms and an average added mole number of ethylene oxide of 1.5 to 4 and a liquid oil and hydrophobized A method of combining treated particulate metal oxide powders is disclosed. Patent Document 4 uses a combination of cross-linked polyether-modified silicone, fluorine-modified silicone, and fluorine compound-treated powder to uniformly adhere to the skin crevice and skin hill, and has good adhesion to the entire skin. A method is disclosed in which a finish with an inconspicuous texture is obtained. Patent Document 5 includes a crosslinked polyether-modified silicone, a dextrin fatty acid ester and / or an inulin fatty acid ester, an acrylamide thickener, and a powder. Disclosed is a method for obtaining a water-in-oil emulsified cosmetic having excellent properties and stability over time. Patent Document 6 discloses zinc oxide, a cross-linked copolymer of acrylamide and 2-acrylamido-2-methylpropane sulfonic acid and / or an acrylic acid / acryloyldimethyltaurine sodium copolymer, a nonionic surfactant having an HLB of 10 or more, and / or By blending an anionic surfactant, water and silicone oil and dispersing zinc oxide in an oil system containing silicone oil, it has excellent storage stability over time, good usability, and transparency after use. A method for obtaining an oil-in-water emulsified cosmetic excellent in water resistance and water resistance is disclosed. However, even if water resistance is imparted to an oil-in-water emulsion cosmetic blended with titanium oxide or zinc oxide using conventional techniques described in Patent Documents 3 to 6, titanium oxide and zinc oxide are likely to aggregate. However, there is still a problem that sufficient storage stability cannot be obtained. Moreover, when apply | coating to the skin in a dry state, it did not come to obtain sufficient elongation and a breadth. Therefore, in the conventional method, sufficient application uniformity cannot be obtained, and the original sunscreen effect of the sunscreen cosmetic cannot be obtained.

JP-A-6-157237 JP2015-17080 A JP 2014-114274 A JP 2014-101311 A Japanese Patent No. 5219142 JP 2005-272389 A

  The present invention has been made in view of the above-described conventional situation, and by having a coating uniformity that can obtain sufficient elongation and spread, a uniform UV prevention effect without unevenness is obtained, and as a result, sufficient An object is to provide a sunscreen cosmetic that exhibits a sunscreen effect.

  As a result of diligent research to solve the above-mentioned problems, the present inventor significantly improved the coating uniformity by blending a sunscreen cosmetic with an ultraviolet absorber and an alkaligenes-producing polysaccharide.

Further, a water-soluble ultraviolet absorbent or an oil-soluble ultraviolet absorbent is appropriately selected according to the dosage form of the target product.

  The compounding quantity of the ultraviolet absorber used for this invention is 0.01 to 50 weight% with respect to the total amount of sunscreen cosmetics, Preferably, it is 0.05 to 25 weight%. If it is less than 0.01% by weight, the sunscreen effect may be poor, and the UV-preventing effect with a blending amount exceeding 50% by weight is practically unnecessary and uneconomical.

  The alkaline-genes-producing polysaccharide used in the present invention is a high molecular compound and is sold by Hakuto Co., Ltd. under the trade name “Arcasilan”. The blending amount of the alkaligenes-producing polysaccharide is 0.001 to 1% by weight, preferably 0.01 to 0.5% by weight, based on the total amount of the sunscreen cosmetic. More preferably, it is 0.02 to 0.1% by weight. If it is less than 0.001% by weight, the effect of application uniformity may not be sufficiently exhibited, and if it exceeds 1% by weight, the viscosity of the preparation increases, and thus the effect of application uniformity may not be sufficiently exhibited.

  The alkaline genus-producing polysaccharide used in the present invention is a hydrophilic polymer and has an affinity for water, but has a weaker water affinity than a general hydrophilic polymer, and therefore the present invention includes the alkaline-genes-producing polysaccharide. When sunscreen cosmetics are applied to the skin, water is continuously and moderately released by applied finger pressure and shearing force. By improving the lubricity due to the continuously released water, the sunscreen cosmetic of the present invention can be stretched and applied uniformly over a wide range.

  In general water-soluble synthetic polymers and polysaccharides, hydroxyl groups and the like have affinity with water molecules in water, and the number of affinity sites with water increases because it spreads in string form and network form in water. Thereby, once water is held, it becomes difficult to release water. On the other hand, the alkaligenes-producing polysaccharide does not spread in water, has a spherical shape like a yarn ball, and has very few affinity sites with water. Then, the alkaline-genes-producing polysaccharide in a spherical shape is connected in a bead-like manner, and is stretched and entangled in a fibrous form to form a micro network. This is a micro sponge that does not dissolve in water. The water that has entered the mesh is released in accordance with the pressure during application.

  In the present invention, the ultraviolet scattering agent used in the present invention is used for improving the ultraviolet ray preventing effect. Examples of the ultraviolet scattering agent include titanium oxide, fine particle titanium oxide, zinc oxide, fine particle zinc oxide, iron oxide, fine particle iron oxide, and cerium oxide. The blending amount is appropriately determined in the range of 0.1 to 50% by weight, preferably 0.5 to 25% by weight, and more preferably 3 to 20% by weight with respect to the total amount of the sunscreen cosmetic. If the blending amount is 0.1% by weight or less, a sufficient ultraviolet light scattering effect may not be obtained. On the other hand, if it is 50% by weight or more, an effect commensurate with the blending amount may not be obtained, and the skin may be dyed into a powder color. It gets worse.

A sample was applied to a square acrylic plate with a side of 5 cm, and SPF values at 9 different locations were measured, and the ultraviolet ray prevention effect was evaluated based on measurement variations.
Used SPF measuring device; UV-2000S SPF analyzer (manufactured by Labsphere)

A 5 cm × 5 cm acrylic plate is divided into 25 sections of 1 cm ² , and 1.3 mg of sample is weighed on each section. Next, with a finger, the sample is extended 5 times on one side and 4 sides. 15 minutes after application, SPF values are measured at 9 places in total, one in each of 3 × 3 sections in the center of 25 sections. The average value, standard deviation, and coefficient of variation were determined from the nine SPF values and are shown in Table 6.

The variation coefficient of Examples 1 to 4 is in the range of 15 to 20%, but the variation coefficient of Comparative Examples 1 to 4 is 27 to 40%, and the variation of the SPF value in the measurement part is less in the Examples. Uniform UV protection effect is obtained without unevenness. This result shows that the sunscreen cosmetic of the present invention has a coating uniformity with which sufficient elongation and spread can be obtained, and therefore, a uniform UV prevention effect without unevenness was obtained.
