Description
【0001】
【産業上の利用分野】
本発明は、マルチトールモノ脂肪酸エステル及びジグリセリンを含む皮膚洗浄料、さらに詳しくは高い安定性、使用性を有する皮膚洗浄料に関するものである。
【0002】
【従来の技術】
皮膚を美しく保つためには、余分な皮脂や老廃物、汚れ等を除去し、皮膚を清潔にすることが必要である。特に皮脂は、光の暴露によって過酸化脂質を生成し、皮膚に対して炎症等を引き起こすことがあり、皮膚を洗浄するということは非常に重要なことである。
【0003】
皮膚洗浄料として最も広く普及しているものとしては固形石鹸があるが、顔面を洗浄するものとしてはクリーム状洗浄料が一般的である。このクリーム状洗浄料の主成分は脂肪酸石鹸のものが一般的である。この脂肪酸石鹸は炭素数が12から22までのものを組み合わせることにより使用性の高いクリーム状の剤型を得ることができる。また、洗浄性を向上したり、皮膚刺激を低減したりする目的で、これらの脂肪酸石鹸にヤシ油脂肪酸メチルタウリン塩などのタウリン系活性剤、ラウロイルサルコシン塩などのアルキルサルコシネート系活性剤、N−ヤシ油脂肪酸−L−グルタミン酸塩などのアシルアミノ酸系活性剤などの陰イオン性界面活性剤やラウリルジメチルアミノ酢酸ベタインなどのベタイン系活性剤などの両性界面活性剤などを配合することも多い。また、保湿性や皮膚刺激を低減するため、グリセリンなどの多価アルコールを配合することも一般的なことである。
【0004】
【発明が解決しようとする課題】
脂肪酸石鹸の選択として、洗浄性の観点からみれば炭素数の少ないラウリン酸塩やミリスチン酸塩などを多く含むことが望ましいが、剤型的に適度な硬度のものを得ることは容易なことではない。また、脂肪酸塩の融点の低さから高温部や経日変化における安定性には問題がある。さらに、ラウリン酸塩は他の脂肪酸塩に比較して皮膚刺激があることも問題になる。高温部や経日変化における安定性を良好なものとするには炭素数の多いステアリン酸塩やベヘニン酸塩などをある程度含むことが望ましいが、これらのものを多く含めば泡立ちの悪さや水なじみの悪さなど使用性には問題がある。
【0005】
【課題を解決するための手段】
本発明者らは、クリーム状洗浄料にマルチトールモノ脂肪酸エステル及びジグリセリンを配合することにより、炭素数の少ない脂肪酸塩を多く含むようなものでも適度な硬度を有しつつ、高温部や経日変化における安定性に優れていることを見出し、本発明を完成するに至った。
【0006】
以下本発明について詳述する。本発明で必須成分として使用されるマルチトールモノ脂肪酸エステルにおける脂肪酸は、炭素数12のラウリン酸から炭素数18のステアリン酸であり、飽和、不飽和もしくは直鎖、分岐のいずれの脂肪酸もこれに含まれる。そして、好ましくはラウリン酸である。
【0007】
また、このマルチトールモノ脂肪酸エステル中にマルチトールジ脂肪酸エステルやマルチトールトリ脂肪酸エステルなどの他の脂肪酸エステル、もしくは他の不純物が含まれていてもよい。
【0008】
本発明におけるマルチトールモノ脂肪酸エステルの配合量は特に限定されないが、好ましくは0.1〜20%、さらに好ましくは0.5〜5%である。0.1%以下では、安定性向上の効果に乏しく、特に40℃で1ヶ月保存した場合にベース状態が硬くなり、使用性の面でも問題がある。20%以上では、他の洗浄成分の配合量が減少し、洗浄剤としての効果が損なわれ、また、ベース状態も柔らかくなる傾向がある。
【0009】
そして、一方の必須成分として使用されるジグリセリンについてもグリセリンやトリグリセリン、テトラグリセリンなどのポリグリセリン、もしくは他の不純物が含まれていてもよい。
【0010】
本発明におけるジグリセリンの配合量は特に限定されないが、好ましくは0.1〜30%、さらに好ましくは1〜20%である。0.1%以下では、安定性向上の効果に乏しく、ベース状態も硬くなる傾向がある。30%以上では、他の洗浄成分の配合量が減少し、洗浄剤としての効果が損なわれ、また、ジグリセリンのべたつきが強くなり、使用性の面でも好ましくない。
【0011】
本発明は脂肪酸塩を主成分とするものに限定されるものではなく、例えばN−アシル−L−グルタミン酸塩等のアシルアミノ酸塩を主成分とするものや脂肪酸塩以外の適当な陰イオン性界面活性剤、両性界面活性剤、ヤシ油脂肪酸ジエタノールアミドなどのアミド系活性剤によって構成されるクリーム状、ゲル状の洗顔料など通常知られている洗顔料にも有用である。
【0012】
さらに本発明の皮膚洗浄料は、発明の効果を損なわない範囲で、その使用目的に応じて色素、香料、界面活性剤、ジグリセリン以外の多価アルコール、ホホバ油などの保湿剤、グリチルリチン酸ジカリウムなどの消炎剤、その他目的に応じた水溶性、油溶性の様々な成分を適宜配合することが可能である。
【0013】
また、本発明の皮膚洗浄料は、マルチトールモノ脂肪酸エステルを配合するため、特開平1−1511にあるように、良好な使用性を有し、また、安全性も高いものである。ジグリセリンを配合することにより、高い保湿力を有し、これによっても良好な使用性を有する。

[Industrial application fields]
The present invention relates to a skin cleanser comprising maltitol monofatty acid ester and diglycerin, and more particularly to a skin cleanser having high stability and usability.
[0002]
[Prior art]
In order to keep the skin beautiful, it is necessary to remove excess sebum, waste products, dirt, etc., and to clean the skin. In particular, sebum generates lipid peroxides by exposure to light and may cause inflammation and the like on the skin, and it is very important to wash the skin.
[0003]
The most widely used skin cleanser is a solid soap, but a cream cleanser is generally used to clean the face. The main component of this creamy detergent is generally fatty acid soap. This fatty acid soap can obtain a creamy dosage form with high usability by combining those having 12 to 22 carbon atoms. In addition, for the purpose of improving detergency and reducing skin irritation, these fatty acid soaps include taurine-based active agents such as coconut oil fatty acid methyl taurine salt, alkyl sarcosinate-based active agents such as lauroyl sarcosine salt, In many cases, an anionic surfactant such as an acylamino acid type active agent such as N-coconut oil fatty acid-L-glutamate or an amphoteric surfactant such as a betaine type active agent such as lauryldimethylaminoacetic acid betaine is often added. . It is also common to add a polyhydric alcohol such as glycerin in order to reduce moisture retention and skin irritation.
[0004]
[Problems to be solved by the invention]
It is desirable to select a fatty acid soap from the viewpoint of detergency, but it is desirable to contain a large amount of laurate, myristate, etc. with a small number of carbon atoms. Absent. Moreover, there is a problem in the stability of the fatty acid salt in the high temperature part and changes over time due to the low melting point. Furthermore, laurate has a problem of skin irritation compared to other fatty acid salts. It is desirable to include stearates and behenates with a large number of carbons in order to improve the stability at high temperatures and changes over time, but if many of these are included, poor foaming and familiarity with water There is a problem in usability such as badness.
[0005]
[Means for Solving the Problems]
The inventors of the present invention have blended maltitol monofatty acid ester and diglycerin into a creamy detergent, so that even those containing a large amount of fatty acid salts having a small number of carbon atoms have an appropriate hardness, while having high hardness and The present inventors have found that it is excellent in stability in daily change, and have completed the present invention.
[0006]
The present invention is described in detail below. The fatty acid in the maltitol monofatty acid ester used as an essential component in the present invention is lauric acid having 12 carbon atoms to stearic acid having 18 carbon atoms, and any of saturated, unsaturated, linear, and branched fatty acids can be used. included. And preferably it is lauric acid.
[0007]
The maltitol monofatty acid ester may contain other fatty acid esters such as maltitol difatty acid ester and maltitol trifatty acid ester, or other impurities.
[0008]
Although the compounding quantity of the maltitol mono-fatty acid ester in this invention is not specifically limited, Preferably it is 0.1 to 20%, More preferably, it is 0.5 to 5%. If it is 0.1% or less, the effect of improving the stability is poor, and particularly when stored at 40 ° C. for 1 month, the base state becomes hard, and there is a problem in terms of usability. If it is 20% or more, the blending amount of other cleaning components decreases, the effect as a cleaning agent is impaired, and the base state tends to be soft.
[0009]
And diglycerin used as one essential component may also contain glycerin, triglycerin, polyglycerin such as tetraglycerin, or other impurities.
[0010]
Although the compounding quantity of the diglycerol in this invention is not specifically limited, Preferably it is 0.1 to 30%, More preferably, it is 1 to 20%. If it is 0.1% or less, the effect of improving the stability is poor, and the base state tends to be hard. If it is 30% or more, the blending amount of other cleaning components decreases, the effect as a cleaning agent is impaired, and the stickiness of diglycerin becomes strong, which is not preferable in terms of usability.
[0011]
The present invention is not limited to a fatty acid salt as a main component, for example, those having an acyl amino acid salt as a main component such as N-acyl-L-glutamate or a suitable anionic interface other than a fatty acid salt. It is also useful for commonly known facial cleansers such as cream-like and gel-like facial cleansers composed of active agents, amphoteric surfactants, amide-based active agents such as coconut oil fatty acid diethanolamide.
[0012]
Further, the skin cleanser of the present invention is a pigment, a fragrance, a surfactant, a polyhydric alcohol other than diglycerin, a moisturizer such as jojoba oil, dipotassium glycyrrhizinate, and the like, within a range that does not impair the effects of the invention. It is possible to mix various anti-inflammatory agents such as water-soluble and oil-soluble components according to the purpose.
[0013]
In addition, since the skin cleanser of the present invention contains maltitol mono-fatty acid ester, it has good usability and high safety as disclosed in JP-A-1-1511. By blending diglycerin, it has high moisturizing power, and this also has good usability.
[0014]
