Description
本発明は、（Ａ）酸化チタン、および（Ｂ）トルエンスルホン酸またはその塩を含有する化粧料に関する。 The present invention relates to a cosmetic containing (A) titanium oxide and (B) toluenesulfonic acid or a salt thereof.
光学的効果を利用して、人の外観印象を変えるものとして、メークアップ化粧料が使用されている。光学効果を奏する成分としては、酸化チタン、酸化亜鉛、酸化鉄、群青、紺青等の顔料類や、タルク、セリサイト、マイカ、チタンマイカ、チタンセリサイト、シリカ、アルミナ、珪酸カルシウム、珪酸マグネシウム或いは炭酸カルシウムなどの無機成分が知られている。これらの顔料類や無機成分は、凝集力が高いために皮膚に塗布する際、伸ばしにくく、肌へのなじみが悪いという傾向があるが、さらにこれらの光学特性が汗や皮脂などにより変化した場合、外観印象が大きく変わる、所謂「化粧崩れ」が起こることが知られている。本発明者らは、化粧崩れの原因について詳細に検討したところ、汗の中の塩分による酸化チタンの凝集が一因であることを見出した。 Makeup cosmetics are used to change the appearance of people using optical effects. As components having optical effects, pigments such as titanium oxide, zinc oxide, iron oxide, ultramarine and bitumen, talc, sericite, mica, titanium mica, titanium sericite, silica, alumina, calcium silicate, magnesium silicate or Inorganic components such as calcium carbonate are known. These pigments and inorganic components tend to be difficult to stretch when applied to the skin due to their high cohesive strength, and they are not well-familiar with the skin, but if these optical properties change due to sweat or sebum, etc. It is known that so-called “decoration of makeup” occurs in which the appearance impression changes greatly. The inventors of the present invention have examined in detail the cause of makeup break-up, and have found that the aggregation of titanium oxide due to salt in sweat is one cause.
このため、前記顔料類や無機成分を高分子化合物で被覆する方法（特許文献１）等により、酸化チタンの凝集を防ぐ工夫がされているが、その効果は十分なものではなかった。 For this reason, although the method of coat | covering the said pigments and an inorganic component with a high molecular compound (patent document 1) etc. is devised to prevent aggregation of titanium oxide, the effect is not sufficient.
また、酸化チタンは、紫外線遮蔽能を有する物質であり、紫外線を防止する目的でも化粧料に配合される。しかしながら、光照射や高熱処理に対する安定性に問題があり、化粧料を変色または着色させる場合があった。そこで、酸化チタンの配合量を減少させ、紫外線遮蔽能を有する別の物質を配合するなどの工夫がされているが、化粧料の紫外線遮蔽性が低下したり、刺激性やアレルギーなどの問題を引き起こすことがあった。 Titanium oxide is a substance having an ultraviolet shielding ability and is blended in cosmetics for the purpose of preventing ultraviolet rays. However, there is a problem in stability against light irradiation and high heat treatment, and the cosmetics may be discolored or colored. Therefore, it has been devised to reduce the compounding amount of titanium oxide and to mix another substance having ultraviolet shielding ability, but the ultraviolet shielding property of cosmetics is reduced, problems such as irritation and allergy There was a cause.
一方、トルエンスルホン酸は、毛髪のまとまりを改善するために毛髪化粧料に使用される成分である（例えば、特許文献２）が、皮膚化粧料としての有用性については知られていなかった。 On the other hand, although toluenesulfonic acid is a component used for hair cosmetics in order to improve the unity of hair (for example, patent document 2), the usefulness as skin cosmetics was not known.
