この発明は、サンスクリーン剤として４−５用なファン

合粒子に関する。DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to composite particles suitable for use as a sunscreen agent in cosmetics such as 4-5 foundations.
（従来の技術）
人体が太陽光に当たると、その紫外線によって、皮膚が
、黒化したり、老化が促進されるなど、健康上あるいは
美容上、好ましからぬ影響が起こる。(Prior Art) When the human body is exposed to sunlight, the ultraviolet rays cause unfavorable health or beauty effects, such as darkening of the skin and accelerated aging.
そのため、サンスクリーン剤として使用するファンデー

して遮断するための物質が配合されている。Therefore, cosmetics such as foundations used as sunscreen agents usually contain substances that reflect or absorb and block ultraviolet rays.
そのような紫外線遮断物質としては、従来、特開昭６３

は、酸化ジルコニウムによる紫外線の反射率は高いが、
反射しきれなかった紫外線が母材粒子を容易に透過して
しまい、紫外線の遮断効果が十分でないという問題があ
る。Conventionally, such ultraviolet blocking substances have been disclosed in JP-A-63
Composite particles described in Japanese Patent No.-27532 are known. These conventional composite particles are made by supporting zirconium oxide powder on the surface layer of base material particles made of a nylon resin copolymerized with nylon 6 and nylon 12, and the zirconium oxide powder mainly reflects and blocks ultraviolet rays. It is supposed to be done. However, although this conventional composite particle has a high reflectance of ultraviolet rays due to zirconium oxide,
There is a problem in that the unreflected ultraviolet rays easily pass through the base material particles, and the ultraviolet ray blocking effect is not sufficient.

善が望まれている。Further, JP-A-61-194010 describes composite particles in which titanium oxide or zinc oxide powder is supported on the surface of base material particles made of nylon 6 resin, nylon 12 resin, or the like. This is because titanium oxide and zinc oxide on the surface mainly absorb and block ultraviolet rays. However, since these conventional composite particles have titanium oxide and zinc oxide on their surface, which have a high UV absorption effect, if they are used in cosmetics, they may cause discoloration of oils and fats or, in severe cases, cause skin irritation. Improvements are desired.

複合粒子を提供するにある。(Problems to be Solved by the Invention) The purpose of the present invention is to solve the above-mentioned problems of the conventional composite particles, to have excellent ultraviolet blocking effects, and to prevent rough skin etc. even when used in cosmetics. The goal is to provide composite particles that cause fewer concerns.

At least one powder selected from zirconium oxide and aluminum oxide is supported on the surface of the base material particles, and at least one powder selected from titanium oxide and zinc oxide is supported inside the base material particles. At least one selected
A composite particle is provided characterized in that a seed powder is dispersed therein.

イロン１２との共重合樹脂が好ましい。To explain this invention in more detail, the base material particles are made of nylon resin, polyethylene resin, polymethyl methacrylate resin, polyester resin, polystyrene resin, polyurethane resin, silicone resin, or silicon oxide. Among these, nylon resin, silicone resin, and silicon oxide are preferred. There are various nylon resins, but nylon 6 resin, nylon 12 resin, and copolymer resin of nylon 6 and nylon 12 are preferred.

る。The shape of the base material particles described above is preferably spherical, but may also be columnar, rod-shaped, plate-shaped, or the like. The average particle diameter is in the range of 0.5 to 100 μm, preferably 2 to 20 μm when the shape is spherical, and 1 to 100 μm in terms of spherical shape, preferably 5 to 2 O
It is within the range of L1m. When the average particle diameter of the base material particles is within the range mentioned above, the powders of zirconium oxide and aluminum oxide that mainly reflect ultraviolet rays, which will be described later, can be sufficiently supported on the surface. Furthermore, powders of titanium oxide and zinc oxide, which will be described later and mainly have the function of absorbing ultraviolet rays, can be sufficiently dispersed inside. Moreover, when the average particle diameter of the base material particles is within the above-mentioned range, when the composite particles are blended into the cosmetic 1, the user is less likely to feel uncomfortable.

化アルミニウムの粉末は、複合粒子に、主として、紫外
線の反射作用を与えるものである。The zirconium oxide or aluminum oxide powder supported on the surface of the base material particles mainly gives the composite particles an ultraviolet reflection effect.
