Description

【0001】
【発明の属する技術分野】
本発明は、低pHにおいても長期にわたり美しい真珠光沢を維持する真珠光沢液及びこれを配合した毛髪化粧料に関する。
【0002】
【従来の技術】
シャンプーやコンディショナーなどに代表される毛髪化粧料は、髪や頭皮を清潔に保つことや髪に滑らかさやまとまりを付与するという基本的な性能のほか、製品の外観も、消費者に様々なイメージを与えるため、商品としての観点からは重要な要素である。その一つとして、真珠光沢があり、高級感や効果感を演出する。パール化剤としては、一般に、様々な化合物の板状や針状のミクロ結晶粒子が使用されている。最も代表的なものとして、エチレングリコール脂肪酸エステルが挙げられ、製品中で直接冷却晶析させる方法や、前もって濃厚分散液を調製し、製品に配合する方法が用いられている。
【0003】
市販されているエチレングリコール脂肪酸エステルは、脂肪酸混合物とエチレングリコールから合成される。その中で、ステアリン酸を主成分とする脂肪酸のジエステルタイプが最も一般的であり、エチレングリコールジステアレート(略称:EGDS)として、広く用いられている。化粧品原料として用いられるEGDSとしては、その原料脂肪酸組成が、50重量%程度を占めるステアリン酸と、炭素数16以下の脂肪酸で構成され、約60℃の融点を有するものが一般的である。この脂肪酸組成は、融点が比較的低いため扱いやすいことや、結晶性の制御が比較的容易なことが利点であるが、高温でのパール外観の維持が難しく、特にpHが低い場合、パール外観の劣化が顕著となることが問題である。これは、パール化剤粒子(EGDS)の溶解や界面活性剤水溶液中への可溶化が促進され、エステル部分が加水分解を受けるためと思われる。
【0004】
また、長鎖脂肪酸グリコールエステルとグリセリルエーテルを併用した、パール化剤の分散安定性に優れた水性液状洗浄剤組成物が知られているが(特許文献1参照)、このもので使用しているEGDSも、一般化粧品原料として用いられるステアリン酸が50重量%程度のものであるため、低pH領域でのパール外観の劣化という問題は解消されていない。毛髪や頭皮のようなタンパク質を処理する剤の場合、目的とする効果がpHに依存する場合が多く、幅広いpH領域にわたり美しいパール外観を維持することは商品として重要である。

【発明が解決しようとする課題】
したがって、本発明は、低pHで美しいパール外観を長期にわたり維持できる真珠光沢液及びこれを配合した毛髪化粧料を提供することを目的とする。
【0007】
【課題を解決するための手段】
本発明者らはEGDSの原料脂肪酸中に含まれるステアリン酸の比率を高めることで、低pHにおいてもパール外観を長期にわたり維持できることを見出した。しかしその一方で、ステアリン酸純度を上げすぎると結晶性の制御が難しくなり、十分なパール外観が得られなくなるという問題も生じた。そこで、本発明者らは、美しいパール外観と、低pHにおけるその維持を両立できるEGDS及びその濃縮分散液について検討した結果、一定範囲のステアリン酸純度を有するEGDSを用いるとともに、界面活性剤成分の一つとして特定のグリセリルエーテルを使用することで上記目的が達成されることを見出した。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a pearlescent liquid that maintains beautiful pearl luster for a long time even at a low pH, and a hair cosmetic containing the same.
[0002]
[Prior art]
Hair cosmetics, such as shampoos and conditioners, provide consumers with a variety of images in addition to their basic performance of keeping hair and scalp clean and giving hair smoothness and cohesion, as well as product appearance. It is an important factor from a product point of view to give. As one of them, it has a pearl luster and produces a sense of quality and effect. Generally, plate-like or needle-like microcrystal particles of various compounds are used as the pearling agent. The most typical example is an ethylene glycol fatty acid ester, and a method of directly cooling and crystallizing in a product, or a method of preparing a concentrated dispersion in advance and blending it with the product is used.
[0003]
Commercially available ethylene glycol fatty acid esters are synthesized from a fatty acid mixture and ethylene glycol. Among them, the diester type of fatty acid containing stearic acid as a main component is the most common, and is widely used as ethylene glycol distearate (abbreviation: EGDS). EGDS used as a cosmetic raw material generally has a fatty acid composition composed of stearic acid occupying about 50% by weight and a fatty acid having 16 or less carbon atoms and having a melting point of about 60 ° C. This fatty acid composition has the advantage that it is easy to handle because of its relatively low melting point, and that it is relatively easy to control the crystallinity. However, it is difficult to maintain the pearl appearance at high temperatures, especially when the pH is low, There is a problem that the deterioration of remarkable becomes significant. This is presumably because the dissolution of the pearlizing agent particles (EGDS) and the solubilization in the aqueous surfactant solution are promoted, and the ester portion undergoes hydrolysis.
[0004]
In addition, an aqueous liquid detergent composition which uses a long chain fatty acid glycol ester and glyceryl ether in combination and has excellent dispersion stability of a pearlizing agent is known (see Patent Document 1), and is used in this composition. In EGDS, stearic acid used as a raw material for general cosmetics is about 50% by weight, so that the problem of deterioration of pearl appearance in a low pH range has not been solved. In the case of agents for treating proteins such as hair and scalp, the desired effect often depends on pH, and maintaining a beautiful pearl appearance over a wide pH range is important as a commercial product.
[0005]

[Problems to be solved by the invention]
Therefore, an object of the present invention is to provide a pearlescent liquid capable of maintaining a beautiful pearl appearance at a low pH for a long period of time and a hair cosmetic containing the same.
[0007]
[Means for Solving the Problems]
The present inventors have found that the pearl appearance can be maintained for a long time even at a low pH by increasing the ratio of stearic acid contained in the raw material fatty acid of EGDS. However, on the other hand, if the stearic acid purity is too high, it is difficult to control the crystallinity, and there has been a problem that a sufficient pearl appearance cannot be obtained. Thus, the present inventors have studied EGDS and its concentrated dispersion liquid that can achieve both a beautiful pearl appearance and its maintenance at a low pH, and as a result, while using EGDS having a certain range of stearic acid purity, For example, it has been found that the above object can be achieved by using a specific glyceryl ether.

【Example】
Examples 1 to 5 and Comparative Examples 1 to 6 30% by weight of pearlescent liquid, 16.7% by weight of an aqueous solution of amidopropyl betaine laurate, 7.0% by weight of glycerin isodecyl ether and the stearic acid purity shown in Table 1 (in the fatty acid composition) Ethylene glycol distearate (EGDS) having a ratio of stearic acid of the formula (1) was added to the purified water and stirred at 80 ° C. After confirming that EGDS was completely melted and uniformly dispersed, the EGDS was stirred and cooled at a rate of 0.5 ° C./min. The mixture was further stirred for 30 minutes while maintaining the temperature at which heat generation and viscosity increase were confirmed. Thereafter, the mixture was cooled to 30 ° C. with stirring to obtain various pearlescent liquids shown in Tables 2 and 3.
[0035]
The appearance of the resulting pearlescent liquid was visually observed, and the results of evaluating the pearl appearance based on the following criteria are shown in Tables 2 and 3.
[0036]
-Evaluation criteria for pearl appearance ◎: Very beautiful pearl appearance.
:: beautiful pearl appearance.
Δ: Weak pearl appearance.
X: Cloudy.
