- the present invention relates to a hair oil using an oily gel composition. More specifically, hair oil in which lecithin and a specific polyglycerin or / and a specific polyglycerin fatty acid ester gel forming agent are blended with an oil component, the spread during use is smooth, and the finish is supple.
- the present invention relates to a hair oil that is excellent in lightness, moist and easy to unite, and also has a glossy effect.
- Hair oil is a type of hair cosmetic used for the purpose of supplementing the hair with oil and giving it gloss, smoothness, flexibility and the like.
- hair oil conventionally, vegetable oils such as camellia oil and olive oil, and mineral oils such as liquid paraffin have been used as main components.
- higher fatty acids, silicone oils, and the like have been added to this to adjust the feeling of use (for example, see Non-Patent Document 1).
- various types of silicone oils having different structures and molecular weights have been used in order to give smoothness, flexibility and finish during use and after use.
- high molecular weight silicone has been used in combination with low molecular weight silicone or volatile silicone (for example, see Patent Documents 1 and 2).
- oil compositions generally have a low viscosity, and there is a problem that when applied to hair, the oil composition flows down between fingers or is applied to an unintended hair site.
- oily component was prepared with an existing gelling agent, the extensibility when applied was very poor.
- an object of the present invention is to provide a hair oil that has a smooth and smooth extension during use, and that gives a smooth finish, lightness, moist feeling, ease of grouping, and gloss.

Abstract
Description
ゲル形成剤と油相成分とからなる油性ゲル状組成物を含むヘアオイルであって、
該ゲル形成剤が、レシチン100重量%に対して、ポリグリセリン及びポリグリセリン脂肪酸エステルから選択される少なくとも1種を5~100重量%(合計量)配合したものであり、
該ポリグリセリンの重合度が2~20であり、
該ポリグリセリン脂肪酸エステルが、炭素数が14以下の脂肪酸残基を有し、有機概念図で算出されるHLBが15以上であり、重合度8~40であることを特徴とするヘアオイルを提供する。
本発明にいう油性ゲル状組成物とは、水を含まないか、あるいは極微量(例えば、1重量%以下、好ましくは0.2重量%以下)しか含まないゲル状組成物をいう。油性ゲル状組成物としては、ゲル形成剤と油相成分とからなればよく、特に限定されない。
本発明のヘアオイルにおいてゲル形成剤は、レシチン100重量%に対して、ポリグリセリン及びポリグリセリン脂肪酸エステルから選択される少なくとも1種を5~100重量%(合計量)配合したものであるが、5~80重量%の範囲が好ましく、10~50重量%の範囲がより好ましい。含有量が少なすぎると、ゲル形成能が著しく低下するため好ましくない。また、含有量が多すぎると、ポリグリセリン誘導体自体が可溶化されずに白濁した組成になる上に著しく粘度低下を引き起こす。したがって、上記範囲で含有することが好ましい。
本発明で用いる油相成分は、極性油のみ、あるいは極性油と非極性油の混合物、あるいは非極性油を主成分とする。非極性油としては、スクワラン、ワセリン、流動パラフィン等の炭化水素類、鎖状または環状のシリコーン油等を挙げることができる。極性油の例としては、オリーブ油等の油脂類、ラノリン等のロウ類、ミリスチン酸イソプロピル、オレイン酸デシル、2-エチルヘキサン酸セチル、トリ-2-エチルヘキサン酸グリセリン等のエステル類[炭素数8以上(好ましくは、炭素数8~25)の脂肪酸とアルコールとのエステル等]、オレイン酸、ラウリン酸等の高級脂肪酸類[炭素数12以上(好ましくは、炭素数12~25)の脂肪酸等]、セタノール等の常温で固体の高級アルコール類[炭素数12以上(好ましくは、炭素数12~25)のアルコール等]等を挙げることができる。これら油相成分の含有量は、油性ゲル状組成物全量に対し、70~99重量%の範囲で、単独あるいは組み合わせて配合される。油相成分の含有量が70重量%より低濃度ではゲル形成剤の量が多くなりすぎ、また、99重量%を越えるとゲルの安定性が悪くなり、さらに経済的でないことから上記範囲が好ましい。油相成分の含有量は、油性ゲル状組成物全量に対して、70~99重量%が好ましく、80~97重量%がより好ましい。
本発明に用いられるポリグリセリン脂肪酸エステルは様々な方法を用いて製造される。例えば、(1)グリセリンにグリシドールを付加重合した後、これに脂肪酸でエステル化する方法、(2)グリシドールを脂肪酸に付加する方法、またこれに関連して(3)水酸基を保護したグリシドールをグリセリンに付加した後、脱保護をし、これを任意の重合度になるまで繰り返したあと、これに脂肪酸でエステル化する方法、(4)アルカリ存在下でグリセリンを熱縮合させたあと、これに脂肪酸でエステル化する方法が挙げられる。このうち、最も好ましい製造方法は(1)の方法であり、当該油性ゲル状組成物のゲル形成剤として好適に用いることができる。
HLB=Σ無機性/Σ有機性×10 (A)
(参考文献:日本エマルジョン(株)「有機概念図による乳化処方設計」)
本発明に用いられるポリグリセリンは様々な方法を用いて製造される。例えば、(1)エピクロルヒドリンをグリセリンに付加重合した後、アルカリ条件下で脱塩化水素閉環し、次いで希硫酸で開環する操作を目的の重合度に達するまで繰り返す方法、(2)グリシドールをグリセリンに付加する方法、またこれに関連して(3)水酸基を保護したグリシドールをグリセリンに付加した後、脱保護をし、これを任意の重合度になるまで繰り返す方法、(4)アルカリ存在下でグリセリンを熱縮合させる方法、(5)グリセリンにハロゲン化アリルを付加させエポキシ化後、水で開環し、これを任意の重合度になるまで繰り返す方法等が挙げられる。なかでも、最も好ましい製造方法は(2)の方法であり、当該ヘアオイルのゲル形成剤として好適に用いることができる。
レシチンは、ホスファチジルコリンを主成分とする脂質製品であり、天然の動物、植物、微生物等の生体に広く分布するもので、肝臓、卵黄、大豆、酵母等に多く含まれることが知られている。代表的なレシチンとして、卵黄レシチン、大豆レシチン等が挙げられる。レシチンは単独で又は2種以上を混合して用いることができる。レシチンとしては、ホスファチジルコリンの含有量が55~99重量%程度のものが好ましい。この範囲のものは、クリーム状となりやすく、適度の稠度があり、肌につけたときに流れ落ちたりせず、使用感が良好である。天然のレシチンは、L-α-形のみであるが、それ以外のものも使用可能である。天然のレシチンは酸化されやすく、不安定であるので、使用に際しては、公知の方法により水素添加しておけばよい。本発明では、このような水素添加されたレシチンも「レシチン」に含まれる。
本発明のヘアオイルは、上記油性ゲル状組成物の他に、本発明の効果を損なわない質的量的範囲で、通常の毛髪化粧料に用いられる成分を適宜配合しても良い。前記成分としては、水性成分、非水性成分のいずれであってもよいが、好ましくは非水性成分である。前記成分としては、例えば、油性成分、界面活性剤、多価アルコール、ポリオール、キレート化剤、殺菌剤、酸化防止剤、粘度調整剤、収れん剤、抗フケ剤、紫外線吸収剤、染料・色素等の着色剤、香料、ビタミン等の美容成分、エアゾール噴射剤等が挙げられる。
