Description
本発明は、紫外線防御効果を有する日焼け止め用の化粧料に関する。 The present invention relates to a sunscreen cosmetic having an ultraviolet protection effect.
無機紫外線散乱剤を配合した日焼け止め化粧料は肌に塗布することにより、肌表面で紫外線を防御する効果を有する。従来の前記無機紫外線散乱剤としては、一般に微粒子金属酸化物が用いられている。無機紫外線散乱剤は、通常屈折率が高いため透明性が低く、該無機紫外線散乱剤を多量に配合した化粧料の塗布によって肌の白さが気になったり、また肌へ塗布した際にきしみやざらつき等が生じることが見られている。
したがって、無機紫外線散乱剤の配合量を抑えても充分な紫外線防御効果が得られるように、無機紫外線散乱剤配合による紫外線防御効果をより有効に引き出す技術開発が行われてきた。
Sunscreen cosmetics containing an inorganic ultraviolet scattering agent have an effect of protecting ultraviolet rays on the skin surface when applied to the skin. As the conventional inorganic ultraviolet scattering agent, a fine particle metal oxide is generally used. Inorganic UV scattering agents usually have a low refractive index due to their high refractive index, and skin whiteness is a concern when cosmetics containing a large amount of the inorganic UV scattering agent are applied. It has been observed that roughness and the like occur.
Accordingly, technology development has been carried out to more effectively bring out the ultraviolet protection effect of the inorganic ultraviolet scattering agent so that a sufficient ultraviolet protection effect can be obtained even if the blending amount of the inorganic ultraviolet scattering agent is suppressed.
この開発には、従来から、例えば、分散剤の配合や、無機紫外線散乱剤の表面処理等により、無機紫外線散乱剤の化粧料中における分散性を上げる技術によって解決を図ろうとしているが、十分な効果が得られていない。
また、最近、板状ヒドロキシアパタイト及び無機紫外線遮蔽剤を含有する日焼け止め化粧料（特許文献１参照）が提案されているが、効果が十分でない。
For this development, conventionally, for example, attempts have been made to solve the problem by increasing the dispersibility of the inorganic ultraviolet scattering agent in the cosmetic by, for example, blending the dispersant or surface treatment of the inorganic ultraviolet scattering agent. The effect is not acquired.
Recently, sunscreen cosmetics (see Patent Document 1) containing plate-like hydroxyapatite and an inorganic ultraviolet shielding agent have been proposed, but the effect is not sufficient.
一方、管状塩基性炭酸マグネシウムを化粧料に配合することについては、皮脂中の脂肪酸の種類を問わず固定化することができ、種々の原因による化粧崩れに対する防止効果に優れた化粧料（特許文献２参照）、高温において安定性を保持し、きしみ感を有さない、かつ伸び広がりのよい化粧料用油性ゲル状組成物及びそれを含む化粧料（特許文献３参照）、化粧料を塗布した際の「のび」、「なめらかさ」、「べたつきのなさ」等の使用感に優れ、落下強度、保存安定性にも優れる油性固型化粧料（特許文献４参照）、微粒子を管状塩基性炭酸マグネシウム調製中の管状凝集粒子の形成過程で添加して得られる、前記微粒子が管状凝集粒子内部、特に内壁に固定化されて内包された微粒子内包複合管状塩基性炭酸マグネシウムを含有する医薬又は化粧料（特許文献５参照）等が知られているが、無機紫外線散乱剤含有化粧料中に管状塩基性炭酸マグネシウムを添加して無機紫外線散乱剤による紫外線防御効果を向上させる技術に応用されることについては知られていない。 On the other hand, regarding the incorporation of tubular basic magnesium carbonate into cosmetics, it can be fixed regardless of the type of fatty acid in sebum, and is a cosmetic that has an excellent effect of preventing makeup collapse due to various causes (Patent Documents) 2), an oily gel composition for cosmetics that retains stability at high temperatures, does not have a squeaky feeling, and has a good spread, and cosmetics containing the same (see Patent Document 3) and cosmetics were applied. Oily solid cosmetics (see Patent Document 4) excellent in feeling of use such as “nobi”, “smoothness”, “no stickiness”, and excellent in drop strength and storage stability, and tubular basic carbonate A medical agent containing fine particulate inclusion composite tubular basic magnesium carbonate in which the fine particles obtained by adding in the formation process of the tubular aggregated particles during the preparation of magnesium are fixed inside the tubular aggregated particles, particularly the inner wall. Alternatively, cosmetics (see Patent Document 5) are known, but they are applied to a technique for improving the UV protection effect of inorganic UV scattering agents by adding tubular basic magnesium carbonate into cosmetics containing inorganic UV scattering agents. There is no known about that.
本発明は上記事情に鑑みてなされたもので、その目的は、無機紫外線散乱剤配合によって奏される日焼け止め化粧料の紫外線防御効果を有効に発揮させる技術を開発することにある。すなわち、日焼け止め化粧料に配合される無機紫外線散乱剤配合によってもたらされる日焼け止め化粧料の紫外線防御効果を処方の組み立てによって向上させることを目的とする。 This invention is made | formed in view of the said situation, The objective is to develop the technique which exhibits the ultraviolet-ray protective effect of the sunscreen cosmetics show | played effectively by inorganic ultraviolet-scattering agent mixing | blending. That is, it aims at improving the ultraviolet-ray protective effect of the sunscreen cosmetics brought about by the mixing | blending of the inorganic ultraviolet scattering agent mix | blended with a sunscreen cosmetics by prescription assembly.

すなわち、本発明は、一次粒子の平均粒子径が１〜１００ｎｍである微粒子金属酸化物からなる無機紫外線散乱剤及び油分を含有した日焼け止め化粧料であり、油分を５〜８０質量％、この油分中に無機紫外線散乱剤として疎水性微粒子金属酸化物を１〜３０質量％及び管状塩基性炭酸マグネシウムを０．０１〜１０質量％配合し、剤形が油型、油中水型又は水中油型の液又はクリームであることを特徴とする日焼け止め化粧料である。 That is, the present invention is a sunscreen cosmetic containing an inorganic ultraviolet scattering agent comprising a fine particle metal oxide having an average primary particle diameter of 1 to 100 nm and an oil component, and the oil content is 5 to 80% by mass. Contains 1 to 30% by weight of hydrophobic fine particle metal oxide and 0.01 to 10% by weight of tubular basic magnesium carbonate as an inorganic ultraviolet scattering agent, and the dosage form is oil type, water-in-oil type or oil-in-water type. A sunscreen cosmetic characterized by being a liquid or cream.
また、金属酸化物が酸化チタン、酸化亜鉛及び酸化セリウムからなる群から選ばれた１種又は２種以上である日焼け止め化粧料である。 Also, metallic oxide is titanium oxide, one or more der Ru day sunscreen cosmetics selected from the group consisting of zinc oxide, and cerium oxide.
また、本発明は、疎水性微粒子金属酸化物からなる無機紫外線散乱剤及び油分を含有したＳＰＦ値を有する日焼け止め化粧料に、管状塩基性炭酸マグネシウムを配合してＳＰＦ値を上昇させる方法である。 The present invention also provides a sunscreen cosmetic having SPF values containing inorganic ultraviolet scattering agent and oil consisting of a hydrophobic particulate metal oxide, by blending a tubular basic magnesium carbonate in the process of increasing the S PF value is there.
本発明において、ＳＰＦ（ｓｕｎ ｐｒｏｔｅｃｔｉｏｎ ｆａｃｔｏｒ）とは、紫外線のうち、肌がヒリヒリと赤くなるような炎症（サンバーン）をひき起こす傾向の強いＵＶＢ波を遮断する効果の程度を表す指標、すなわちＵＶＢ防御指数であり、皮膚が紫外線を浴びはじめてから赤い斑点が生じはじめるまでの時間を何倍に引き延ばすことができるかを表したものである。 In the present invention, SPF (sun protection factor) is an index that represents the degree of the effect of blocking UVB waves, which have a strong tendency to cause inflammation (sunburn) in the ultraviolet rays, which causes the skin to become tingling and red. It is an index and represents how many times the time from when the skin begins to be exposed to ultraviolet rays until when red spots start to appear can be extended.
本発明の日焼け止め化粧料は、疎水性微粒子金属酸化物からなる無機紫外線散乱剤を管状塩基性炭酸マグネシウムとともに配合することにより、無機紫外線散乱剤の配合による紫外線防御効果を有効に発揮させることができ、日焼け止め化粧料として化粧品分野に応用される。 The sunscreen cosmetic of the present invention can effectively exhibit the UV protection effect due to the blending of the inorganic UV scattering agent by blending the inorganic UV scattering agent made of hydrophobic fine particle metal oxide together with the tubular basic magnesium carbonate.
