Description
【０００１】
【発明が属する技術分野】
本発明は低刺激パック化粧料に関する。更に詳細には、ｐＨ安定性に優れた、皮膚に対する刺激性が低い弱酸性のパック化粧料に関する。
【０００２】
【従来の技術】
フェイス、ボディ用のパック化粧料には、ピールオフタイプ、拭き取りタイプ、洗い流しタイプなど種々のものがあるが、いずれの剤型も皮膚に適度な厚さに塗布し、一定時間放置後、剥離したり、拭き取り、洗い流すことによって、皮膚の保湿・賦活・皮膚表面の汚垢除去を図っている。
【０００３】
このようなパック化粧料のうち、とくに毛穴の汚れなど汚垢の除去に重点を置いた剤型に、カオリナイト、スメクタイト、ベントナイト等ケイ酸塩鉱物を主成分として含有したものがある。
【０００４】
しかしながら、こういったケイ酸塩鉱物、とくに増粘性を有する該成分を主体とするパック化粧料は、配合成分の性質上、示性ｐＨが７．０以上のアルカリ性を示すことが多く、使用法上、皮膚上に比較的長時間塗付する必要があるため、アルカリ過敏症の人が皮膚刺激を感じるという問題があった。また調製当時は弱酸性であっても長期的にはｐＨが上昇し、安定性に問題が生じる。
【０００５】
こういった問題を解決するため、パック化粧料のｐＨを下げる手段として酸による中和が考えられるが、長期的にｐＨを弱酸性に維持することは難しい。例えば代表的な中和剤である乳酸を用いる場合、ｐＨを弱酸性に維持するためには２重量％以上のごとく多量に配合する必要があり、その結果他の成分の配合が制限されたり、大量配合そのものによる刺激を感じることがあった。
【０００６】
【発明が解決しようとする課題】
本発明の目的は、経時的にｐＨが上昇することなく安定性に優れ、皮膚に対し低刺激の弱酸性のパック化粧料を提供することにある。
【０００７】
【課題を解決するための手段】
かかる実情において、本発明者は鋭意研究を行った結果、後述する成分を組み合わせることにより、経時的にｐＨが上昇することなく安定性に優れ、かつ皮膚に対し刺激性が低い弱酸性のパック化粧料が得られることを見出し、本発明を完成するに至った。
すなわち、本発明は、
１．ｐＨ調整剤と増粘性を有するケイ酸塩鉱物とを含有し、系のｐＨが７．０未満の弱酸性である液状の低刺激パック化粧料であって、
ケイ酸塩鉱物がベントナイトであり、含有量が２〜５．５質量％であり、
ｐＨ調整剤がカルボキシビニルポリマーであり、含有量が０．０５〜０．２質量％であることを特徴とする液状の低刺激パック化粧料。
に関する。
【０００８】
【発明の実施の形態】
本発明で用いられるｐＨ調整剤としては、カルボキシビニルポリマー等を挙げることができる。カルボキシビニルポリマーは１％水溶液にしてｐＨが３〜５の範囲である。このような成分の配合量は、本発明の低刺激パック化粧料中０．０２〜０．４重量％が好ましく、特に０．０５〜０．３重量％とすることが好ましい。
【０００９】
また、無水ケイ酸は一般に球状の微粒子粉体であり、皮膚に対する物理的な刺激が少ない成分である。このような成分の配合量は、本発明の低刺激パック化粧料中１〜１５重量％が好ましく、特に２〜１０重量％とすることが好ましい。無水ケイ酸は、パック化粧料において、ｐＨ調製剤として作用することができる。本発明の低刺激パック化粧料はｐＨが７．０未満に安定的に保持される。このようにして得られる低刺激パック化粧料は、弱酸性であり長時間塗布しても刺激感が抑制されている。
【００１０】
本発明における低刺激パック化粧料には、増粘性を有するケイ酸塩鉱物を含有する。該成分としては代表的なものとしてモンモリロナイトを主成分としたベントナイト等が挙げられる。
【００１１】
ケイ酸塩鉱物の配合量は、塗付時の使用性の点から、本発明化粧料全量中に１．５〜６．５重量％であるのが好ましく、特に２〜５．５重量％とすることが好ましい。
【００１２】
本発明の低刺激パック化粧料は、上記成分のほかに、通常のパック化粧料に含まれる保湿剤、界面活性剤、多価アルコール、低級アルコール、油剤、防腐剤、薬剤、香料、着色剤、水等が配合される。
【００１３】
本発明の低刺激パック化粧料は、常法により製造することができ、例えば、増粘性ケイ酸塩鉱物に、水、多価アルコール、保湿剤等の成分を混合、分散後、ここに低級アルコール等のアルコール相を加え、混合する等の方法により得ることができる。本発明の低刺激パック化粧料は、ボディ、フェイスに通常の使用方法により用いることができる。
【００１４】
【実施例】
次に、本発明を実施例によりさらに詳細に説明するが、本発明はこれによって限定されるものではない。なお、配合量はすべて重量％である。
実施例に先立ち、各実施例で用いた試験法、評価法を説明する。

【発明の効果】
以上詳述したように、本発明によれば、ｐＨ安定性に優れた、刺激性の低い、フェイス、ボディ用弱酸性のパック化粧料が得られる。[0001]
[Technical field to which the invention belongs]
The present invention relates to a hypoallergenic pack cosmetic. More specifically, the present invention relates to a weakly acidic pack cosmetic having excellent pH stability and low skin irritation.
[0002]
[Prior art]
There are various types of face and body pack cosmetics such as peel-off type, wipe-off type, and wash-off type. The skin is moisturized, activated, and decontaminated on the skin surface by wiping and washing away.
[0003]
Among such pack cosmetics, there are those containing silicate minerals such as kaolinite, smectite, and bentonite as main components, especially in dosage forms with an emphasis on removing dirt such as pore dirt.
[0004]
However, pack cosmetics mainly composed of such silicate minerals, particularly those having a thickening property, often exhibit an alkaline pH of 7.0 or more due to the properties of the blended components. In addition, since it is necessary to apply on the skin for a relatively long time, there is a problem that people with alkali sensitivity feel skin irritation. Moreover, even if it is weakly acidic at the time of preparation, the pH rises in the long term, causing a problem in stability.
[0005]
In order to solve these problems, neutralization with an acid can be considered as a means for lowering the pH of the pack cosmetic, but it is difficult to maintain the pH weakly acidic over the long term. For example, when using lactic acid, which is a typical neutralizing agent, it is necessary to blend in a large amount such as 2% by weight or more in order to maintain the pH at weak acidity. As a result, the blending of other components is limited, I sometimes felt irritation due to the large amount of ingredients.
[0006]
[Problems to be solved by the invention]
It is an object of the present invention to provide a weakly acidic pack cosmetic which is excellent in stability without increasing its pH with time and has low irritation to the skin.
[0007]
[Means for Solving the Problems]
Under such circumstances, the present inventor has conducted earnest research, and as a result, by combining the components described later, a weakly acidic pack makeup that is excellent in stability without increasing pH over time and has low irritation to the skin. The present inventors have found that a charge can be obtained and have completed the present invention.
That is, the present invention
1. A liquid hypoallergenic pack cosmetic comprising a pH adjusting agent and a silicate mineral having a thickening viscosity, wherein the pH of the system is weakly acidic and less than 7.0,
The silicate mineral is bentonite, the content is 2 to 5.5% by mass,
A liquid hypoallergenic pack cosmetic characterized in that the pH adjuster is a carboxyvinyl polymer and the content is 0.05 to 0.2% by mass.
About.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
Examples of the pH adjuster used in the present invention include carboxyvinyl polymer. The carboxyvinyl polymer has a 1% aqueous solution and a pH in the range of 3-5. The blending amount of such components is preferably 0.02 to 0.4% by weight, particularly preferably 0.05 to 0.3% by weight, in the hypoallergenic pack cosmetic of the present invention.
[0009]
Silicic anhydride is generally a spherical fine particle powder, and is a component with little physical irritation to the skin. The blending amount of such components is preferably 1 to 15% by weight in the hypoallergenic pack cosmetic of the present invention, and particularly preferably 2 to 10% by weight. Silicic anhydride can act as a pH adjuster in pack cosmetics. The hypoallergenic pack cosmetic of the present invention is stably maintained at a pH of less than 7.0. The hypoallergenic pack cosmetic obtained in this way is weakly acidic and the irritation is suppressed even when applied for a long time.
[0010]
The hypoallergenic pack cosmetic according to the present invention contains a silicate mineral having a thickening property. Typical examples of the component include bentonite mainly composed of montmorillonite.
[0011]
The blending amount of the silicate mineral is preferably 1.5 to 6.5% by weight, particularly 2 to 5.5% by weight in the total amount of the cosmetic of the present invention, from the viewpoint of usability at the time of application. It is preferable to do.
[0012]
In addition to the above components, the hypoallergenic pack cosmetic of the present invention includes a moisturizer, surfactant, polyhydric alcohol, lower alcohol, oil, preservative, drug, fragrance, colorant, Water etc. are blended.
[0013]
The hypoallergenic pack cosmetic of the present invention can be produced by a conventional method. For example, after mixing and dispersing components such as water, a polyhydric alcohol and a humectant into a thickening silicate mineral, It can obtain by methods, such as adding and mixing alcohol phases, such as. The hypoallergenic pack cosmetic of the present invention can be used on the body and face by a normal method of use.
[0014]

Prior to the examples, test methods and evaluation methods used in the examples will be described.
[0015]
[Stability] After preparing the sample, appropriate amounts were taken on the day of preparation and 30 days later, and measured with a pH meter (Horiba, Ltd .; pH / ION METER F-32). The evaluation was performed according to the following criteria, with the difference between the day of preparation and the value measured after 30 days.
