Description
本願発明は、高い紫外線防御効果を持ち、経時安定性に優れ、良好な使用感を有し、さらには使用後の落としやすさにも優れる油中水型乳化化粧料に関する。 The present invention relates to a water-in-oil emulsified cosmetic having a high UV protection effect, excellent stability with time, good usability, and excellent ease of removal after use.
地上に降り注ぐ紫外線のうちＵＶＡ領域（３２０〜４００ｎｍ）は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り、ＵＶＢ領域（２８０〜３２０ｎｍ）は短時間で皮膚が赤くなる日焼けの原因となると言われている。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。ＵＶＢ波を遮断する効果の程度を表す指標は、ＳＰＦ（ＳＵＮ ＰＲＯＴＥＣＴＩＯＮ ＦＡＣＴＯＲ）、ＵＶＡに対してはＵＶＡＰＦ（ＵＶＡ ＰＲＯＴＥＣＴＩＯＮ ＦＡＣＴＯＲ ＯＦ Ａ ＰＲＯＤＵＣＴ）で表される。 The UVA region (320-400 nm) of ultraviolet rays falling on the ground changes the collagen fibers and elastin fibers of the dermis and causes photoaging which promotes skin aging. The UVB region (280-320 nm) It is said to cause a reddish tan. Therefore, protecting the skin from ultraviolet rays in the two wavelength regions of UVA and UVB is one of the important functions of cosmetics. An index representing the degree of the effect of blocking the UVB wave is represented by SPF (SUN PROTECTION FACTOR), and for UVA, UVAPF (UVA PROTECTION FACTOR OF A PRODUCT).
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、耐汗性の点で、油中水乳化型組成物が良好であることが知られている。 Sunscreen cosmetics are used to prevent the adverse effects of the ultraviolet rays on the skin, and it is known that the water-in-oil emulsion composition is good in terms of sweat resistance.
従来から紫外線防御効果を付与するために、日焼け止め化粧料には酸化チタンや酸化亜鉛等の無機系紫外線防御剤やケイ皮酸系等の有機系紫外線吸収剤等が汎用されてきた（非特許文献１〜３）。 Conventionally, in order to impart an ultraviolet protection effect, sunscreen cosmetics have been widely used inorganic UV protection agents such as titanium oxide and zinc oxide, and organic UV absorbers such as cinnamic acid (non-patent) Literatures 1-3).
近年、日焼け止め化粧料には特にＵＶＡ領域の紫外線防御への要求が高まってきており、ＵＶＡ領域の紫外線吸収剤の一つとして、ジエチルアミノヒドロキシベンゾイル安息香酸ヘキシルが使用されている（特許文献１及び２）。しかしながら、高い紫外線防御効果を求め、ジエチルアミノヒドロキシベンゾイル安息香酸ヘキシルを多量に配合する場合、溶剤となる油剤の量が不足すると低温で析出するなど経時安定性が低下してしまい、油剤の量が多くなりすぎると、べたつきが生じのびが不十分である等の使用感の問題が生じる。 In recent years, there has been an increasing demand for sunscreen cosmetics especially in the UVA region, and diethylaminohydroxybenzoyl hexyl benzoate is used as one of UV absorbers in the UVA region (Patent Document 1 and 2). However, when seeking a high UV protection effect and adding a large amount of diethylaminohydroxybenzoyl hexyl benzoate, if the amount of the oil agent that is the solvent is insufficient, the stability over time decreases, such as precipitation at low temperatures, and the amount of oil agent is large. If it becomes too much, stickiness occurs and problems of feeling of use such as insufficient spread arise.
一方、近年では高い日焼け止め効果を有するクリーム、美容液、乳液などのスキンケア剤が好まれて用いられる。そのため、高い紫外線防御効果を持ちながらも、なめらかで伸びがよく落としやすい等の使用感の優れた日焼け止め化粧料が強く望まれている。 On the other hand, in recent years, skin care agents such as creams, serums, and emulsions having a high sunscreen effect are preferred and used. Therefore, there is a strong demand for sunscreen cosmetics that have a high UV protection effect, and that are smooth, easy to stretch and easy to remove.
一般に、油中水型乳化組成物の使用感の向上を目的として揮発性油が汎用されている。しかしながら、揮発性油として揮発性シリコーンを用いた場合、油っぽさは軽減されるものの、シリコーン系基剤に対し紫外線吸収剤は難溶性を呈すため、油相の均一性に劣り、乳化できなかったり、皮膚に対して塗りむらを生じるといった問題があった。また、揮発性油として揮発性炭化水素を用いた場合には、乳化物の経時安定性が低下したり、揮発性シリコーンよりも使用感に劣るという問題があった（特許文献３）。 In general, volatile oils are widely used for the purpose of improving the feeling of use of the water-in-oil emulsion composition. However, when volatile silicone is used as the volatile oil, the oiliness is reduced. However, the ultraviolet absorber exhibits poor solubility with respect to the silicone base, so that the uniformity of the oil phase is poor and emulsification is possible. There was a problem that there was no smearing on the skin. Moreover, when volatile hydrocarbon was used as volatile oil, there existed a problem that stability with time of an emulsion fell or it was inferior to a volatile silicone in usability (patent document 3).
この課題を解決する手段として、ドデカメチルシクロヘキサシロキサンとイソドデカンの併用やイソヘキサデカンとシクロヘキサメチコーンの併用が試みられている（特許文献３及び４）。しかしながら、揮発性シリコーンと揮発性炭化水素の組み合わせにおいて、両方またはどちらか一方の揮発性が不十分であると、ジエチルアミノヒドロキシベンゾイル安息香酸ヘキシルを高配合した場合、油っぽさが残り使用感が満足のいくものではなかったり、乳化物の経時安定性を高めるために界面活性剤の含有量が多くなるという課題があった。 As means for solving this problem, a combined use of dodecamethylcyclohexasiloxane and isododecane or a combination of isohexadecane and cyclohexamethicone has been attempted (Patent Documents 3 and 4). However, in the combination of volatile silicone and volatile hydrocarbon, if both or one of the volatility is insufficient, when hexyl diethylaminohydroxybenzoyl benzoate is highly blended, oiliness remains and the feeling of use remains. There was a problem that the content of the surfactant was increased in order to improve the temporal stability of the emulsion, which was not satisfactory.
本願発明における課題は、高い紫外線防御効果と優れた使用感を有する油中水型乳化化粧料を提供することである。 The subject in this invention is providing the water-in-oil type emulsified cosmetics which have a high ultraviolet-ray protective effect and the outstanding usability | use_condition.

As a specific commercial item, UVINUL A PLUS GRANULAR (made by BASF Japan Ltd.) can be illustrated.
本願発明における成分（Ａ）ジエチルアミノヒドロキシベンゾイル安息香酸ヘキシルの含有量は、日焼け止め化粧料全量に対して３〜１０重量％であり、５〜８重量％であることがより好ましい。含有量が３重量％より低い場合では、ＵＶＡ領域の紫外線に対する防御効果が不十分な場合があり、また、１０重量％より高い場合では、含有量を増加させてもＵＶＡ領域の紫外線に対する防御効果が頭打ちになり、日焼け止め化粧料を塗布する際に伸びが重くなるなどの使用感の低下が生じたり、析出による経時安定性の低下が生じたりする場合があり好ましくない。 The content of component (A) diethylaminohydroxybenzoyl hexyl benzoate in the present invention is 3 to 10% by weight, more preferably 5 to 8% by weight, based on the total amount of the sunscreen cosmetic. When the content is lower than 3% by weight, the UVA region may have an insufficient protective effect against ultraviolet rays. When the content is higher than 10% by weight, even if the content is increased, the UVA region has a protective effect against ultraviolet rays. However, it is not preferable because it may cause a decrease in feeling of use such as an increase in elongation when applying sunscreen cosmetics, or a decrease in stability over time due to precipitation.

本願発明に用いる（Ｃ）揮発性炭化水素は、常圧における沸点が２００℃以下で常温での揮発速度が速いものである。炭素数８〜１４のイソパラフィン系炭化水素が好ましく、特にイソドデカンが好ましい。具体的な市販品としてはマルカゾールＲ（丸善石油化学株式会社製）、パーメチル９９Ａ（ＩＮＥＯＳ ＭＡＮＵＦＡＣＴＵＲＩＮＧ ＤＥＵＴＳＣＨＬＡＮＤ製）が例示できる。 The (C) volatile hydrocarbon used in the present invention has a boiling point of 200 ° C. or less at normal pressure and a fast volatilization rate at room temperature. Isoparaffin hydrocarbons having 8 to 14 carbon atoms are preferred, and isododecane is particularly preferred. Specific examples of commercially available products include Marcazole R (manufactured by Maruzen Petrochemical Co., Ltd.) and Permethyl 99A (manufactured by INEOS MANUFACTURING DUTSCHLAND).
揮発性シリコーン及び揮発性炭化水素で沸点が２００℃より大きいものは、塗布時のさっぱりとした感触を得られず、また他の成分を肌に強く付着させられないため十分な紫外線防御効果が得られない。 Volatile silicone and volatile hydrocarbons with boiling points greater than 200 ° C do not provide a refreshing feel when applied, and other components cannot adhere strongly to the skin, providing sufficient UV protection. I can't.
成分（Ｂ）沸点が２００℃以下の揮発性シリコーンの含有量は５〜２５重量％であり、好ましくは１０〜２０重量％である。また、成分（Ｃ）沸点が２００℃以下の揮発性炭化水素の含有量は５〜２５重量％であり、好ましくは１０〜２０重量％である。 The content of component (B) volatile silicone having a boiling point of 200 ° C. or less is 5 to 25% by weight, preferably 10 to 20% by weight. Moreover, content of a volatile hydrocarbon whose component (C) boiling point is 200 degrees C or less is 5 to 25 weight%, Preferably it is 10 to 20 weight%.

More preferably, it is 0.3 to 0.4. When the weight ratio of the total amount of the component (B) and the component (C) with respect to the total amount of the oil phase is smaller than 0.2, the oily feeling is strong and the feeling of use is deteriorated. Moreover, when the weight ratio of the total amount of the component (B) and the component (C) with respect to the total amount of the oil phase is larger than 0.5, the emulsifiability is deteriorated, so that the amount of the surfactant to be used increases or the stability over time. The problem that becomes worse occurs.
さらに、成分（Ｂ）と成分（Ｃ）との好ましい含有比は、成分（Ｃ）／成分（Ｂ）が０．５〜２の範囲であり、より好ましくは１〜１．５である。成分（Ｃ）／成分（Ｂ）の値が０．５より小さい場合、乳化性が悪くなる。また、含有比が２よりも大きい場合、滑らかな使用感が損なわれるといった使用感の悪化につながる。 Furthermore, as for the preferable content ratio of a component (B) and a component (C), a component (C) / component (B) is the range of 0.5-2, More preferably, it is 1-1.5. When the value of the component (C) / component (B) is smaller than 0.5, the emulsifying property is deteriorated. Moreover, when the content ratio is larger than 2, it leads to deterioration of the feeling of use such that the smooth feeling of use is impaired.
