Description
本発明は、乳化組成物における固形油脂の結晶化防止に関するものである。 The present invention relates to prevention of crystallization of solid fats and oils in an emulsion composition.
乳化組成物は、化粧料、医薬品などの分野において、有用な製剤として広く利用されている。これは、乳化組成物が、相混じりあわない油性成分と水性成分とを均一に分散混合し、両者の長所・特性をあわせもつためである。更に、乳化組成物は、油性成分として様々な形状の油脂、即ち、固形油、半固形油、液状油を含有する。それゆえ、乳化組成物は、様々な機能、使用感触を作り出すことができる。 The emulsified composition is widely used as a useful preparation in the fields of cosmetics, pharmaceuticals and the like. This is because the emulsified composition uniformly disperses and mixes an oily component and an aqueous component that do not mix with each other, and has both advantages and characteristics. Furthermore, an emulsion composition contains fats and oils of various shapes as an oil component, that is, solid oil, semi-solid oil, and liquid oil. Therefore, the emulsified composition can create various functions and use feelings.
ところが、この様々な形状の油脂を含有することが、逆に安定性に大きく影響を及ぼすこととなる。これは、乳化組成物が安定系ではないため、些細な環境の変化が直ちに製剤に影響を及ぼすためである。とりわけ、固形油が結晶化し製剤中にザラザラした析出物となってあらわれ商品価値を損なうものとなる。 However, containing these various types of fats and oils greatly affects the stability. This is because the emulsified composition is not a stable system, so a slight environmental change immediately affects the preparation. In particular, solid oil is crystallized and appears as a coarse precipitate in the preparation, which impairs the commercial value.
この様な問題について、未だ統一した解決策は存在せず、製剤化研究の際の試行錯誤により個々の処方で対応しているのが現状である。 There is still no unified solution for such problems, and the current situation is that each prescription is dealt with by trial and error during formulation research.
解決しようとする問題点は、乳化組成物中に固形油が結晶化析出することである。 The problem to be solved is that solid oil crystallizes and precipitates in the emulsion composition.
本発明は、固形油の結晶化を防ぐため、ショ糖脂肪酸エステルと脂肪酸モノグリセライドとを含有することを特徴とする。 The present invention is characterized by containing a sucrose fatty acid ester and a fatty acid monoglyceride in order to prevent crystallization of solid oil.
本発明によれば、安定性に優れる新規乳化組成物を提供することができる。とりわけ固形油が結晶化し析出物となってあらわれるという問題を防止することができる。 According to the present invention, a novel emulsion composition having excellent stability can be provided. In particular, the problem that solid oil is crystallized and appears as a precipitate can be prevented.
本発明に用いるショ糖脂肪酸エステルは、HLB６以下である。特に好ましくはHLB２以下である。この様なものとしては前記の条件を満たすショ糖脂肪酸エステルであれば特に制限はないが、第一工業製薬株式会社より市販されている「DKエステルR10」が特に好ましく例示できる。また、HLBが６を超えるものであると、本発明の目的を達成することができない。本発明におけるこの様なショ糖脂肪酸エステルの好ましい含有量は、乳化組成物全量に対して、0.01〜10.0重量％であり、特に好ましくは、0.1〜5.0％である。 The sucrose fatty acid ester used in the present invention is HLB 6 or less. Especially preferably, it is HLB2 or less. Such a sucrose fatty acid ester satisfying the above conditions is not particularly limited, but “DK ester R10” commercially available from Daiichi Kogyo Seiyaku Co., Ltd. can be particularly preferably exemplified. If the HLB exceeds 6, the object of the present invention cannot be achieved. The preferable content of such a sucrose fatty acid ester in the present invention is 0.01 to 10.0% by weight, particularly preferably 0.1 to 5.0%, based on the total amount of the emulsified composition.
本発明に用いる脂肪酸モノグリセライドは、HLB７以下である。この様なものとしては前記の条件を満たすショ糖脂肪酸エステルであれば特に制限はなく、本発明における脂肪酸モノグリセライドの好ましい含有量は、乳化組成物全量に対して、0.01〜10.0重量％であり、特に好ましくは、0.1〜5.0％である。 The fatty acid monoglyceride used in the present invention is HLB 7 or less. As such, there is no particular limitation as long as it is a sucrose fatty acid ester that satisfies the above conditions, and the preferable content of the fatty acid monoglyceride in the present invention is 0.01 to 10.0% by weight based on the total amount of the emulsion composition, Most preferably, it is 0.1 to 5.0%.
本発明の組成物には、必要に応じて、本発明の効果を損なわない範囲で化粧料に一般に用いられる各種成分、即ち油性成分、界面活性剤、保湿剤、酸化防止剤、防腐剤、増粘剤等々を配合することができる。In the composition of the present invention, various components generally used in cosmetics, i.e., oily components, surfactants, moisturizers, antioxidants, preservatives, potentiators, are added to the composition of the present invention as necessary. Viscosity agents can be blended.
以下、実施例を挙げて本発明を具体的に説明する。なお、本発明はこれに限定されるものではない。 Hereinafter, the present invention will be specifically described with reference to examples. Note that the present invention is not limited to this.
次に示す処方に従って本発明の乳化組成物を作成した。同時に、この実施例の乳化組成物のショ糖脂肪酸エステルおよび脂肪酸モノグリセライドの各々を除いた比較例１，比較例２を、また両方を除いた比較例３、及びショ糖脂肪酸エステルのＨＬＢ値が６以上用いた比較例４を作成した。 The emulsified composition of the present invention was prepared according to the following formulation. At the same time, Comparative Example 1 and Comparative Example 2 except for each of the sucrose fatty acid ester and fatty acid monoglyceride of the emulsified composition of this example, Comparative Example 3 except both, and the HLB value of the sucrose fatty acid ester is 6 The comparative example 4 used above was created.
更に、実施例１および比較例１、比較例２、比較例３、比較例４を５℃３ヶ月の保存試験にかけたところ、実施例は状態の変化は見られなかったのに対し、比較例２、比較例３及び比較例４は顕著な結晶析出が認められ、比較例１も軽度ではあるが結晶の析出が認められた。これにより、本発明の乳化組成物が安定性に優れ、とりわけ低温環境下において遊離脂肪酸が結晶化し析出物となってあらわれるという問題を防止することができるものであることが判る。 Furthermore, when Example 1 and Comparative Example 1, Comparative Example 2, Comparative Example 3, and Comparative Example 4 were subjected to a storage test at 5 ° C. for 3 months, no change in state was observed in the Examples, whereas Comparative Example In 2, Comparative Example 3 and Comparative Example 4, remarkable crystal precipitation was observed, and in Comparative Example 1 crystal precipitation was also observed although it was mild. Thus, it can be seen that the emulsion composition of the present invention is excellent in stability and can particularly prevent the problem that free fatty acids crystallize and appear as precipitates in a low temperature environment.
実施例１及び比較例１〜比較例４の乳化組成物の処方例と安定性の結果を表1に示す。なお、乳化組成物は通常の製法にて製造し、試料を得た。 Table 1 shows formulation examples and stability results of the emulsion compositions of Example 1 and Comparative Examples 1 to 4. In addition, the emulsion composition was manufactured by the normal manufacturing method, and the sample was obtained.
また、安定性評価について、表1の試料を５℃インキュベーターに約５０ｇガラス容器に３ヶ月間密封保管し、状態変化（結晶の析出状況）を確認した。その評価基準を表２に示す。 For stability evaluation, the samples shown in Table 1 were sealed in a 50 ° C. incubator for about 3 months in a glass container for about 3 months, and the state change (crystal deposition state) was confirmed. The evaluation criteria are shown in Table 2.
本発明は、安定性に優れた乳化組成物である為、化粧料を作る上で広く利用できるものである。 Since the present invention is an emulsified composition having excellent stability, it can be widely used in making cosmetics.
