Abstract
Description
本発明は、特定のポリグリセリン脂肪酸エステルと炭化水素油を含有した油性クレンジング化粧料用組成物、及びこの油性クレンジング化粧料用組成物を含有する化粧料に関する。 The present invention relates to an oil-based cleansing cosmetic composition containing a specific polyglycerin fatty acid ester and a hydrocarbon oil, and a cosmetic containing the oil-based cleansing cosmetic composition.
メイク落としのためのクレンジング化粧料は様々なタイプがあるが、メイクを落とす効果が高く、且つ容易に洗い流せるオイルタイプが主流である。また、入浴時に使用する場合も多く、濡れた手で使用してもクレンジング力が低下しない性能が求められている。 There are various types of cleansing cosmetics for removing makeup, but the oil type, which has a high effect of removing makeup and can be easily washed off, is the mainstream. In addition, it is often used when taking a bath, and there is a demand for performance that does not reduce the cleansing power even when used with wet hands.
流動パラフィンをはじめとする炭化水素油は、クレンジングオイルに配合することで、エステル油では得られない厚みのある塗布感を出すことができる。濡れた手で使用できるクレンジング化粧料として、ポリグリセリン中鎖脂肪酸エステルを配合したクレンジングオイル（例えば、特許文献１参照。）が挙げられるが、炭化水素油の配合量は限定されたものであった。これよりも炭化水素油の配合量を増やすと、低温での保存安定性が悪く、分離してしまうという課題があった。
また、ポリグリセリンと炭素数１８の不飽和又は分岐鎖脂肪酸のエステルを用い、透明性、経時安定性に優れた炭化水素油組成物が提供されている（例えば、特許文献２参照。）。しかしこの炭化水素油組成物は、水と混合することでゲル化してしまい、濡れた手で使用したときの肌への塗布感が悪く、洗い流し時にさっぱりとした感触が得られないという課題があった。
Hydrocarbon oils such as liquid paraffin can be blended with cleansing oils to give a thick coating feeling that cannot be obtained with ester oils. Examples of cleansing cosmetics that can be used with wet hands include cleansing oils containing polyglycerin medium-chain fatty acid esters (see, for example, Patent Document 1), but the amount of hydrocarbon oils to be blended is limited. .. If the blending amount of the hydrocarbon oil is increased more than this, there is a problem that the storage stability at a low temperature is poor and the hydrocarbon oil is separated.
Further, a hydrocarbon oil composition having excellent transparency and stability over time is provided by using an ester of polyglycerin and an unsaturated or branched fatty acid having 18 carbon atoms (see, for example, Patent Document 2). However, this hydrocarbon oil composition has a problem that it gels when mixed with water, the feeling of application to the skin is poor when used with wet hands, and a refreshing feel cannot be obtained when rinsing. rice field.
本発明の課題は、炭化水素油を含有する低温保存安定性が高い組成物及びこれを含有する化粧料であって、濡れた手で使用することができ、さらに、汎用されているエステル油では得られなかった厚みのある塗布感を出すことができる油性クレンジング化粧料用組成物、及びこの油性クレンジング化粧料用組成物を含有する化粧料を提供することにある。 An object of the present invention is a composition containing a hydrocarbon oil and having high low-temperature storage stability and a cosmetic containing the same, which can be used by wet hands and is a general-purpose ester oil. It is an object of the present invention to provide a composition for an oil-based cleansing cosmetic that can give a thick coating feeling that could not be obtained, and a cosmetic containing the composition for an oil-based cleansing cosmetic.
本発明者らは上記課題を解決するために鋭意努力した結果、特定の２種以上のポリグリセリン脂肪酸エステルを組み合わせることで、クレンジング化粧料に炭化水素油を安定的に含有できることを見出し、本発明の完成に至った。 As a result of diligent efforts to solve the above problems, the present inventors have found that a hydrocarbon oil can be stably contained in a cleansing cosmetic by combining two or more specific polyglycerin fatty acid esters, and the present invention has been made. Has been completed.
本発明の油性クレンジング化粧料用組成物、及びこの油性クレンジング化粧料用組成物を含有したクレンジング化粧料は、厚みのある塗布感を出すのに十分な炭化水素油を含有し、低温保存時でも分離や濁りが発生せず、高い低温保存安定性がある。本発明の油性クレンジング化粧料用組成物、及びこの油性クレンジング化粧料用組成物を含有したクレンジング化粧料では、塗布時には厚みがあり、洗い流した時の乳化粒子径も小さく、さっぱりとしたべたつきのない感触を得ることができる。さらに、洗い流した後はしっとりとした感触を出すことができる。 The oil-based cleansing cosmetic composition of the present invention and the cleansing cosmetic containing the oil-based cleansing cosmetic composition contain sufficient hydrocarbon oil to give a thick coating feeling, even during low-temperature storage. It has high low temperature storage stability without separation or turbidity. The composition for oil-based cleansing cosmetics of the present invention and the cleansing cosmetics containing this composition for oil-based cleansing cosmetics are thick at the time of application, have a small emulsified particle size when washed off, and are not sticky. You can get a feel. Furthermore, it can give a moist feeling after being washed away.
以下、本発明を詳細に説明する。
本発明の油性クレンジング化粧料用組成物は、成分（Ａ）、（Ｂ）として特定の２種以上のポリグリセリン脂肪酸エステル、及び成分（Ｃ）として炭化水素油を含有する。
Hereinafter, the present invention will be described in detail.
The oil-based cleansing cosmetic composition of the present invention contains two or more specific polyglycerin fatty acid esters as the components (A) and (B), and a hydrocarbon oil as the component (C).

The component (A) is not particularly limited, but is at least one selected from the group consisting of, for example, hexaglyceryl dicaprylate, hexaglyceryl tricaprylate, decaglyceryl pentacaprylate, decaglyceryl hexacaprylate, and the like. Can be mentioned.
本発明における成分（Ｂ）のポリグリセリン脂肪酸エステルは、炭素数１８の不飽和及び／又は分岐鎖脂肪酸とポリグリセリンのジエステルである。構成する脂肪酸が直鎖飽和脂肪酸の場合、油性クレンジング化粧料用組成物中で低温保存時に結晶化し、低温保存安定性が悪くなる。成分（Ｂ）としては、特に限定されるものではないが、例えば、ジオレイン酸デカグリセリル、ジオレイン酸ヘキサグリセリル、ジイソステアリン酸デカグリセリル等からなる群より選択される少なくとも一種以上が挙げられる。 The polyglycerin fatty acid ester of the component (B) in the present invention is an unsaturated and / or branched chain fatty acid having 18 carbon atoms and a diester of polyglycerin. When the constituent fatty acids are linear saturated fatty acids, they crystallize in the oil-based cleansing cosmetic composition during low-temperature storage, and the low-temperature storage stability deteriorates. The component (B) is not particularly limited, and examples thereof include at least one selected from the group consisting of decaglyceryl dioleate, hexaglyceryl dioleate, decaglyceryl diisostearate, and the like.
本発明における成分（Ａ）と（Ｂ）のポリグリセリン脂肪酸エステルを構成するポリグリセリンの平均重合度の算出方法は、以下の式に基づいて、水酸基価より決定される。水酸基価は公知の方法により測定した。
ＯＨＶ＝５６１１０（ｎ＋２）／（７４ｎ＋１８）
ＯＨＶ：ポリグリセリンの水酸基価
ｎ：ポリグリセリンの平均重合度
The method for calculating the average degree of polymerization of polyglycerin constituting the polyglycerin fatty acid esters of the components (A) and (B) in the present invention is determined from the hydroxyl value based on the following formula. The hydroxyl value was measured by a known method.
OHV = 56110 (n + 2) / (74n + 18)
OHV: Hydroxyl value of polyglycerin n: Average degree of polymerization of polyglycerin
本発明における成分（Ａ）及び（Ｂ）のポリグリセリン脂肪酸エステルは、ポリグリセリンと脂肪酸とを常法によるエステル化や、脂肪酸とグリシドールを付加重合することにより容易に得られる。ポリグリセリンと脂肪酸とのエステル化は、特に限定されるものではないが、例えば、ポリグリセリンと脂肪酸を、酸触媒（リン酸、ｐ－トルエンスルホン酸等）もしくはアルカリ触媒（苛性ソーダ等）存在下、又は無触媒で水を除去しながら、好ましくは１００～３００℃、より好ましくは１２０～２６０℃の範囲で加熱することにより行うことができる。また、反応は不活性ガスの存在下で行ってもよい。このようにして得られたエステルは目的に応じて精製しても良い。精製には減圧下での蒸留、分子蒸留、水蒸気蒸留といった蒸留技術の他、有機溶剤による抽出、分画や合成吸着剤、ゲル濾過剤を充填したカラムによるクロマト分離も利用できる。なお、脂肪酸のかわりに、脂肪酸のエステルを用い、ポリグリセリンとエステル交換を行うことにより、目的のポリグリセリン脂肪酸エステルを得ても良い。 The polyglycerin fatty acid esters of the components (A) and (B) in the present invention can be easily obtained by esterifying polyglycerin and fatty acid by a conventional method or by addition polymerization of fatty acid and glycidol. The esterification of polyglycerin and fatty acid is not particularly limited, but for example, polyglycerin and fatty acid are subjected to the presence of an acid catalyst (phosphate, p-toluenesulfonic acid, etc.) or an alkaline catalyst (caustic soda, etc.). Alternatively, it can be carried out by heating in the range of preferably 100 to 300 ° C., more preferably 120 to 260 ° C. while removing water without a catalyst. Moreover, the reaction may be carried out in the presence of an inert gas. The ester thus obtained may be purified depending on the intended purpose. For purification, in addition to distillation techniques such as distillation under reduced pressure, molecular distillation, and steam distillation, extraction with an organic solvent, and chromatographic separation using a column filled with fractionation, synthetic adsorbent, and gel filter can also be used. The desired polyglycerin fatty acid ester may be obtained by transesterifying with polyglycerin using an ester of fatty acid instead of the fatty acid.
