【0001】
【産業上の利用分野】
本発明は、使用時にスポンジやマット等の小道具へのトレが良好で、滑らかでソフトな使用感を有し、肌への付着性に優れ、且つ、成型性及び耐衝撃性に優れた固形粉末化粧料に関するものである。
【0002】
【従来の技術】
従来から、プレスドファンデーション等の固形粉末化粧料は、油剤を多量に配合する方法、粘着性の物質を配合する方法、粉体の凝集力により粉体と粉体を付着させる方法、圧縮する圧力を高める等の機械的方法、等の各種技術により、固形に成型していた。また、使用時にマット等の小道具へのトレを良くするためや、滑らかでソフトな使用感を実現させるため、弾力を有する粉末が用いられていた。
【0003】
【発明が解決しようとする課題】
しかしながら、固形粉末化粧料に油剤や粘着性物質を多量に配合すると、使用時にスポンジやマット等の小道具へのトレが悪くなったり、肌へのベタツキ、伸び広がりの悪さ、肌への負担感、化粧持続性の悪さ等の官能的な問題があった。一方、小道具へのトレや官能面を満足するために少量の油剤しか配合しない固形化粧料では、耐衝撃性が弱く、輸送時や持ち運び時に割れるという強度不足の問題があった。粉体の凝集力を利用する方法では、使用できる粉体が限定されることによる感触の悪さを生じていた。また、機械的に高圧で圧縮する方法においても、使用できる粉体の限定や充填容器の限定があり、更には耐衝撃性は向上するが、スポンジやマット等の小道具へのトレが悪くなるという問題や、弾性を有する粉末を配合した場合は、成型できないといった問題があった。更に、マット等の小道具へのトレを良くするため、また、滑らかでソフトな使用感を実現させるため、弾力を有する粉末を配合すると、弾力を有する粉末が成型時の圧縮力を吸収するため極端に圧縮成型性が悪くなり、結果として耐衝撃性が低下するという問題点があった。このため、これらの問題点を解決した固形粉末化粧料の開発が望まれていた。
【0004】
【課題を解決するための手段】
本発明者は、上記実状において鋭意検討を重ねた結果、特定の固形油粉末と弾性粉末とを組み合わせて用いることにより、使用時にスポンジやマット等の小道具へのトレが良好で、肌への付着性に優れ、滑らかでソフトな使用感を有し、且つ、成型性及び耐衝撃性に優れた固形粉末化粧料が得られることを見出し本発明を完成させた。
【0005】
すなわち本発明は、次の成分(a)及び(b);
(a)融点が85〜125℃で且つ、平均粒子径が0.1〜10μの非球状固形油粉末
(b)弾性粉末
を含有する固形粉末化粧料に関するものである。更に、成分(a)が0.25〜15重量%、成分(b)が0.5〜20重量%であり、且つ、両者の配合重量比が成分(a):成分(b)=0.5:1〜1:0.25である前記の固形粉末化粧料。
また、成分(a)を除く総油分量が5重量%以下である前記の固形粉末化粧料に関するものである。
【0006】
以下、本発明の構成について説明する。
本発明に用いられる成分(a)の固形油粉末は、融点が85〜125℃で且つ、平均粒子径が0.1〜10μの非球状固形油粉末であり、例えば、フィッシャートロプシュワックス、ポリエチレンワックス、エチレンプロピレンコポリマー等の合成炭化水素、マイクロクリスタリンワックス等の鉱物由来の炭化水素、カルナウバワックス等の植物由来のワックス類等の融点が85〜125℃である固形油を微粉砕して得られるものである。
【0007】
前記固形油を粉砕する方法としては、特に限定されるものではないが、通常公知の微粉砕方法である、機械的及び化学的粉砕方法が使用可能である。例えば、機械的粉砕方法としては、ジェットミル、ハンマーミル、ピンミル、ボールミル、ビーズミル、マイクロス、オングミル、ハイブリダイザー、メカノフュージョン等が挙げられ、化学的粉砕方法としては、前記固形油を適当な溶媒に溶かし溶液としたものを噴霧乾燥する方法や、その溶液から固形油を相分離させる方法又は、その溶液を水と乳化しマイクロエマルションとして乾燥させる方法等が挙げられる。また、これらの機械的粉砕と化学的粉砕を複合して用いても良い。粉砕後、必要に応じて、目的の平均粒子径を得るまで固形油粉末を分級することも可能である。
【0008】
成分(a)の固形油粉末は、レーザー回折式粒度分布測定装置(SKレーザーミクロンサイザー セイシン企業社製)にて測定した平均粒子径が0.1〜10μのものであり、0.5〜7μのものがより好ましい。平均粒子径が0.1μ未満であると、固形油粉末の粒子間の凝集力が強くなり、固形粉末化粧料中への分散が困難になることや、肌への付着力が高まり、化粧塗布時に滑らかさがなくなる等の欠点を生じるため好ましくない。また平均粒子径が10μを超えると、粒子間の付着力が弱くなり、固形粉末化粧料の成型性の向上や強度の向上が得られなくなるため好ましくない。
【0009】
また、成分(a)の固形油粉末の形状は、非球状である。球状では固形粉末化粧料の成型性向上効果が低く、非球状の方が固形粉末化粧料の成型性の向上や強度の向上等の効果が優れている。
【0010】
前記非球状粒子とは、球状以外の粒子形状を示し、板状、薄片状、棒状、針状、キュービック状、不定形、等が挙げられる。これら成分(a)の固形油粉末は、一種又は二種以上を用いることができる。
【0011】
本発明の固形粉末化粧料における成分(a)の固形油粉末の配合量は、成分(b)の配合量に依存するが、概ね、0.25〜15重量%(以下、単に「%」で示す)が好ましく、より好ましくは0.5〜10%である。この範囲の配合量であれば、成型性や強度等の本発明の効果がより向上する。
【0012】
本発明に用いられる成分(b)の弾性粉末は、JIS K6301に記載されているスプリング式硬さ試験における硬さ(以下、単に「JIS硬さ」と略す。)が40〜80である素材の粉末である。JIS硬さが、40未満であると付着力が強くなり、分散性が低下し、また肌に対してべとつき感を生じるため、好ましくない。また、JIS硬さが80を超えるとソフトな使用感が減じられるため、好ましくない。このような素材としては、オルガノポリシロキサンエラストマー(JIS硬さ:40〜60)やフロロシリコーンゴム(JIS硬さ:〜70〜)等のシリコーンゴム類、ウレタン類(JIS硬さ:60〜75)、アクリルゴム類(JIS硬さ:〜70〜)、フッ素ゴム類等(JIS硬さ:40〜78)が挙げられるが、中でも、オルガノポリシロキサンエラストマーやウレタン類が、滑らかでソフトな使用感の点より好ましい。
【0013】
成分(b)の弾性粉末の粒径は、0.1〜100μが好ましく、0.5〜20μが更に好ましい。この範囲であると、滑らかでソフトな使用感等の本発明の効果がより向上する。また、粒子形状は、球状が好ましい。これら粉末は市販品として、トレフィルE505、E506、E−701(共に、東レ・ダウコーニング・シリコーン社製)、アートパール(日興ケムテック社製)等が挙げられる。
【0014】
本発明の固形粉末化粧料における成分(b)の弾性粉末の配合量は、成分(a)の配合量に依存するが、概ね、0.5〜20%が好ましく、より好ましくは1〜10%である、この範囲の配合量であれば、滑らかでソフトな使用感を有し、成型性や強度がより向上する。
【0015】
本発明の固形粉末化粧料における成分(a)と成分(b)の配合重量比は、成分(a):成分(b)=0.5:1〜1:0.25が好ましい。この範囲であると、滑らかでソフトな使用感と成型性や強度がより向上する。
【0016】
本発明の固形粉末化粧料には、必要に応じて、成分(a)以外の油分を配合することができる。この油分としては、動物油、植物油、合成油等の起源及び、固形油、半固形油、液体油、揮発性油等の性状を問わず、炭化水素類、油脂類、ロウ類、硬化油類、エステル油類、脂肪酸類、高級アルコール類、シリコーン油類、フッ素系油類、ラノリン誘導体類等が挙げられ、固形油の場合は、他の液体油等に溶解して用いるものである。具体的には、流動パラフィン、スクワラン、ワセリン、ポリイソブチレン、ポリブテン、パラフィンワックス、セレシンワックス、マイクロクリスタリンワックス、モクロウ、モンタンワックス、フィッシャトロプスワックス等の炭化水素類、オリーブ油、ヒマシ油、ホホバ油、ミンク油マカデミアンナッツ油等の油脂類、ミツロウ、ラノリン、カルナウバワックス、キャンデリラワックス、ゲイロウ等のロウ類、セチルイソオクタネート、ミリスチン酸イソプロピル、パルミチン酸イソプロピル、ミリスチン酸オクチルドデシル、トリオクタン酸グリセリル、ジイソステアリン酸ジグリセリル、トリイソステアリン酸ジグリセリル、トリベヘン酸グリセリル、ロジン酸ペンタエリトリットエステル、ジオクタン酸ネオペンチルグリコール、コレステロール脂肪酸エステル、N−ラウロイル−L−グルタミン酸ジ(コレステリル・ベヘニル・オクチルドデシル)等のエステル類、ステアリン酸、ラウリン酸、ミリスチン酸、ベヘニン酸、イソステアリン酸、オレイン酸、ロジン酸、12−ヒドロキシステアリン酸等の脂肪酸類、ステアリルアルコール、セチルアルコール、ラウリルアルコール、オレイルアルコール、イソステアリルアルコール、ベヘニルアルコール等の高級アルコール類、低重合度ジメチルポリシロキサン、高重合度ジメチルポリシロキサン、メチルフェニルポリシロキサン、デカメチルシクロペンタシロキサン、オクタメチルシクロテトラシロキサン、架橋型オルガノポリシロキサン、フッ素変性シリコーン等のシリコーン類、パーフルオロポリエーテル、パーフルオロデカン、パーフルオロオクタン等のフッ素系油剤類、ラノリン、酢酸ラノリン、ラノリン脂肪酸イソプロピル、ラノリンアルコール等のラノリン誘導体類、等が挙げられ、これらを一種又は二種以上用いることができる。
【0017】
本発明の固形粉末化粧料中における、成分(a)以外の油分の総量が5%以下であると、滑らかでソフトな使用感を有しながら成型性及び耐衝撃性が向上するという本発明の効果がより発揮される。

[Industrial application fields]
The present invention is a solid powder that has good torment to props such as sponges and mats when used, has a smooth and soft feeling of use, has excellent adhesion to the skin, and has excellent moldability and impact resistance It relates to cosmetics.
[0002]
[Prior art]
Conventionally, solid powder cosmetics such as pressed foundations have a method of blending a large amount of oil agent, a method of blending a sticky substance, a method of adhering powder and powder by the cohesive force of the powder, a pressure to compress It was molded into a solid by various techniques such as a mechanical method for increasing the viscosity. In addition, elastic powder has been used in order to improve the use of mats and other props during use and to achieve a smooth and soft feel.
[0003]
[Problems to be solved by the invention]
However, if a large amount of oil or sticky substance is added to the solid powder cosmetic, the use of tools such as sponges and mats will worsen during use, the skin will become sticky, the spread will be poor, the burden on the skin, There were sensual problems such as poor makeup persistence. On the other hand, solid cosmetics that contain only a small amount of oil to satisfy the skill and functionality of props have a problem of insufficient strength that they are weak in impact resistance and crack when transported or carried. In the method using the cohesive force of the powder, the feeling of touch is caused by the limited powder that can be used. Also, in the method of mechanically compressing at high pressure, there are limitations on the powders that can be used and the limitations on the filling container, and furthermore the impact resistance is improved, but the training on props such as sponges and mats is worsened. There was a problem that, when a powder having elasticity was blended, it could not be molded. Furthermore, in order to improve the training of props such as mats, and to achieve a smooth and soft feeling of use, when blending elastic powder, the elastic powder absorbs the compression force at the time of molding. However, there is a problem that the compression moldability is deteriorated, and as a result, the impact resistance is lowered. For this reason, development of the solid powder cosmetics which solved these problems was desired.
[0004]
[Means for Solving the Problems]
As a result of intensive studies in the above situation, the present inventor uses a combination of a specific solid oil powder and an elastic powder, so that it can be easily applied to props such as sponges and mats during use, and adheres to the skin. The present invention has been completed by finding that a solid powder cosmetic having excellent properties, smooth and soft feeling of use, and excellent moldability and impact resistance can be obtained.
