Description
本発明は、紫外線吸収剤、揮発性シリコーン及び揮発性炭化水素を含有せず、紫外線防御効果を有するとともに、のびがなめらかで、ずるつきが無く、肌なじみが良く、べたつきが無い油中水型乳化化粧料に関するものである。 The present invention relates to a water-in-oil emulsion cosmetic that does not contain ultraviolet absorbents, volatile silicones, or volatile hydrocarbons, has ultraviolet protection effects, spreads smoothly, is not slippery, blends well with the skin, and is not sticky.
地表に届く紫外線波長領域は、ＵＶＡ領域（３２０～４００ｎｍ）とＵＶＢ領域（２９０～３２０ｎｍ）がある。そのうち、ＵＶＢ領域の紫外線は過度に浴びると皮膚に紅斑を惹起させ、急性の炎症反応を起こし、その後黒化をもたらし、皮膚癌の原因の一つとなることが知られている。また、ＵＶＡ領域の紫外線は、紅斑惹起は弱いが、真皮のコラーゲン線維やエラスチン線維を変質させ、皮膚の老化を促進させる光老化の原因となることが明らかになっている。そのため、ＵＶＡ及びＵＶＢの二つの波長領域の紫外線から肌を守ることは、化粧料の重要な機能の一つである。 The ultraviolet wavelength ranges that reach the earth's surface are the UVA range (320-400 nm) and the UVB range (290-320 nm). Of these, excessive exposure to UVB rays can cause erythema in the skin, triggering an acute inflammatory reaction and subsequent darkening, which is known to be one of the causes of skin cancer. UVA rays are less effective at inducing erythema, but they can alter collagen and elastin fibers in the dermis, causing photoaging, which accelerates skin aging. Therefore, protecting the skin from UVA and UVB wavelength ranges is one of the important functions of cosmetics.
紫外線による肌への悪影響を防御するために、日焼け止め化粧料が使用されており、耐水性や耐汗性の点で、油中水型乳化組成物が良好であることが知られている。通常、日焼け止め化粧料には、紫外線防御効果を付与するために、有機系紫外線吸収剤や無機系紫外線散乱剤等が汎用されている（非特許文献１～３）。有機系紫外線吸収剤は、光エネルギーを吸収することによって紫外線を遮蔽するものであり、高い紫外線防御効果を得られる。しかし、敏感肌の人に対してアレルギー等の皮膚障害を起こす恐れがあるとの知見もあり、消費者の中には、有機系紫外線吸収剤の使用を好まない人もいる。無機系紫外線散乱剤は紫外線を散乱させることによって紫外線を遮蔽するものであり、従来から酸化チタンや酸化亜鉛などが用いられている。これらは広帯域にわたって紫外線を遮蔽することができ、さらに皮膚安全性が高いが、多量に配合するとのびが重くなるといった問題がある。 Sunscreen cosmetics are used to protect the skin from the adverse effects of ultraviolet rays, and it is known that water-in-oil emulsion compositions are good in terms of water resistance and sweat resistance. Usually, organic ultraviolet absorbers and inorganic ultraviolet scattering agents are widely used in sunscreen cosmetics to provide ultraviolet protection (Non-Patent Documents 1-3). Organic ultraviolet absorbers block ultraviolet rays by absorbing light energy, and provide high ultraviolet protection. However, it has been reported that they may cause skin disorders such as allergies in people with sensitive skin, and some consumers do not like the use of organic ultraviolet absorbers. Inorganic ultraviolet scattering agents block ultraviolet rays by scattering them, and titanium oxide and zinc oxide have been used in the past. These agents can block ultraviolet rays over a wide range and are highly safe for the skin, but they have the problem of being heavy to spread when used in large quantities.
この課題に対する具体的な試みとして、基材と紫外線散乱剤を含み、前記基材としてワセリンと揮発性油を含むことを特徴とする皮膚外用剤（特許文献１）が開示されているが、ずるつきを抑え、肌なじみを良くするには至っていない。また、リン脂質及びステリン類を配合せず、日焼け止め組成物の総質量に対して１～２０質量％の尿素を配合することを特徴とする日焼け止め組成物（特許文献２）が開示されているが、のびのなめらかさを改善するには十分ではなく、べたつきを抑えるには至っていない。また、一般に、油中水型乳化組成物のずるつきやべたつきを抑え、肌なじみをよくするために、揮発性シリコーンや揮発性炭化水素が汎用されているが、環境負荷等の観点から、これらの使用を控えるべきだという知見もある。 As a specific attempt to address this issue, a skin topical preparation (Patent Document 1) has been disclosed that contains a base material and an ultraviolet scattering agent, and that the base material contains petrolatum and a volatile oil, but this does not reduce slipperiness or improve skin compatibility. In addition, a sunscreen composition (Patent Document 2) has been disclosed that does not contain phospholipids or sterols, and contains 1 to 20% by mass of urea based on the total mass of the sunscreen composition, but this is not sufficient to improve smoothness of spread and does not reduce stickiness. In addition, volatile silicones and volatile hydrocarbons are generally used to reduce the slipperiness and stickiness of water-in-oil emulsion compositions and improve skin compatibility, but there is also knowledge that their use should be avoided from the perspective of environmental impact, etc.
本発明の目的は、上記課題を解決し、紫外線吸収剤、揮発性シリコーン及び揮発性炭化水素を含有せず、紫外線防御効果を有するとともに、のびがなめらかで、ずるつきが無く、肌なじみが良く、べたつきが無い油中水型乳化化粧料を提供することにある。 The object of the present invention is to solve the above problems and provide a water-in-oil emulsion cosmetic that does not contain ultraviolet absorbers, volatile silicones, or volatile hydrocarbons, has ultraviolet protection effects, spreads smoothly, is not slippery, blends well with the skin, and is not sticky.
