Description
本発明は、アルコキシサリチル酸を含む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 emulsified cosmetic containing alkoxysalicylic acid.
皮膚に対してメラニンの異常沈着を改善または防止する優れた美白効果を有する活性成分として、アルコキシサリチル酸またはその塩が知られている。しかし、一般に、アルコキシサリチル酸またはその塩を油中水型乳化組成物に配合する場合、経時安定性が悪く、場合によって油相と水相との相分離を生じる等の問題があった。
Alkoxysalicylic acid or a salt thereof is known as an active ingredient having an excellent whitening effect for improving or preventing abnormal deposition of melanin on the skin. However, in general, when alkoxysalicylic acid or a salt thereof is blended in a water-in-oil emulsified composition, there are problems such as poor stability over time and in some cases phase separation between the oil phase and the aqueous phase.
このような安定性および使用感の問題を改善するべく、特許文献1には、アルコキシサリチル酸またはその塩を含有する油中水型乳化皮膚外用剤に、緩衝剤として塩類と、重量平均分子量1,000~200,000のポリエチレングリコールとを所定量で配合することが提案されている。
In order to improve such problems of stability and usability, Patent Document 1 describes a water-in-oil emulsified skin external preparation containing alkoxysalicylic acid or a salt thereof, salts as a buffer, and a weight average molecular weight 1, It has been proposed to add 000 to 200,000 polyethylene glycols in a predetermined amount.
また、特許文献2には、アルコキシサリチル酸またはその塩および有機変性粘土鉱物を含有する油中水型乳化組成物に、液状脂肪酸を配合することにより、ガラス、金属、樹脂、陶器などのいずれの材質の容器に収容しても経時の乳化安定性が良好で、べたつきがなく、しっとりとした使用感触を有することが記載されている。
Further, Patent Document 2 describes any material such as glass, metal, resin, and pottery by blending a liquid fatty acid with a water-in-oil emulsified composition containing alkoxysalicylic acid or a salt thereof and an organically modified clay mineral. It is described that the emulsion stability over time is good even when it is contained in the container, it is not sticky, and it has a moist feel.
粘度調整剤や乳化安定剤として、また、しっとりとした使用感触を付与することを目的として、油中水型乳化化粧料に有機変性粘土鉱物を配合することが一般的に行われているが、有機変性粘土鉱物を含む油中水型乳化化粧料にアルコキシサリチル酸またはその塩を配合すると硬度が下がってしまうという問題がある。また、従来のアルコキシサリチル酸またはその塩を配合した油中水型乳化化粧料のコク感やフィット感は、必ずしも満足ができるレベルではないため、さらなる改良が望まれる。硬度を上げようとする場合、一般にはワックスを多量に配合するという手法がとられるが、ワックスを高配合するとべたつきが生じてしまう。
It is common practice to add organically modified clay minerals to water-in-oil emulsified cosmetics as a viscosity modifier, an emulsion stabilizer, and for the purpose of imparting a moist feel. When alkoxysalicylic acid or a salt thereof is added to a water-in-oil emulsified cosmetic containing an organically modified clay mineral, there is a problem that the hardness is lowered. Further, since the richness and fit of the conventional water-in-oil emulsified cosmetic containing alkoxysalicylic acid or a salt thereof are not always at a satisfactory level, further improvement is desired. When trying to increase the hardness, a method of blending a large amount of wax is generally taken, but if a high blending of wax is used, stickiness occurs.
本発明は上記課題に鑑みなされたものであり、適度な硬度がありながらべたつきがなく、コク感やフィット感の良好な油中水型乳化化粧料を提供することを目的とするものである。
The present invention has been made in view of the above problems, and an object of the present invention is to provide a water-in-oil emulsified cosmetic having an appropriate hardness, no stickiness, and a good richness and fit.
