Description

【0001】
【発明の属する技術分野】
本発明は、毛髪に適用する組成物に関し、更に詳しくは毛髪に対して、べたつきがなく、しなやかな感触、良好なセット保持性、再整髪性を有する毛髪化粧料に関する。
【0002】
【従来の技術】
従来、毛髪化粧料には毛髪にしなやかな感触や優れた艶を与える目的でシリコーン油、エステル油、炭化水素油等の液状油を、可溶化、乳化、溶解して用いられている。しかしながら、シリコーン油に代表される油分では、毛髪に対するセット保持性が乏しく、不十分であった。セット保持性を向上するためにこれらの油分を多く配合するとべたつき感がでたり、不自然な艶(てかり)がでるなど満足できるものではなかった。
【0003】
また、毛髪化粧料には毛髪をセットする目的で種々の被膜形成能を有する高分子化合物が用いられている。特にジアルキルアミノエチルメタクリレート重合体の酢酸両性化物、アクリル酸オクチルアクリルアミド/アクリル酸ヒドロキシプロピル/メタクリル酸ブチルアミノエチル共重合体、ビニルピロリドン/ジメチルアミノエチルメタクリレートの4級化物等が汎用されている。しかしながら、これらの高分子化合物はセット保持性に優れているが、ごわつきがあるものであり、また一度形成した皮膜が崩れてしまうと再整髪が困難であるという欠点もあった。
【0004】
これらの欠点を解決すべく、シリコーン等の油分と高分子化合物と組み合わせた毛髪化粧料(特開平2−111711号公報)が提案されているが、このものは毛髪にしなやかな感触や優れた艶を与えるものの、セット保持性を低下させるものであり、満足のゆくものではなかった。
【0005】
【発明が解決しようとする課題】
従って本発明の目的は、毛髪に対して、べたつきがなく、しなやかな感触、良好なセット保持性、再整髪性を有する毛髪化粧料を提供することである。
【0006】
【課題を解決するための手段】
本発明者は、このような状況に鑑み、鋭意研究した結果、皮膜形成能を有する高分子化合物および曳糸性のある水溶性高分子を含有せず、(A)特定の融点を持つ油剤20〜50重量%と(B)特定の融点を持つ油剤1.0〜30重量%と(C)水10〜79重量%とを含有し、成分(A)と成分(B)の重量配合量比(A)/(B)が1.0以上である毛髪化粧料が上記の目的を達成することを見出し、本発明を完成するに至った。
すなわち本発明は、皮膜形成能を有する高分子化合物および曳糸性のある水溶性高分子を含有せず、(A)融点が35〜90℃である油剤20〜50重量%と(B)融点が35℃未満である油剤1.0〜30重量%と(C)水10〜79重量%とを含有し、成分(A)と成分(B)の重量配合量比(A)/(B)が1.0以上であることを特徴とする毛髪化粧料にある。
【0007】
【発明の実施の形態】
本発明の構成要素である成分(A)としては、硬化油、モクロウ等の油脂類、蜜ロウ,カルナウバロウ,キャンデリラロウ,鯨ロウ,ラノリン等のロウ類、パラフィンロウ,マイクロクリスタリンワックス,オゾケライト,ワセリン等の炭化水素油類、ステアリン酸,ミリスチン酸等の高級脂肪酸類、セタノール,ステアリルアルコール等の高級アルコール類、ステアリン酸ブチル,乳酸セチル等のエステル類等が挙げられ、融点が35〜90℃の物を選択して用いる。融点が40℃以上の物が特に好ましい。これらの物質は1種又は2種以上を混合して用いることができ、その配合量としては、20〜50重量%であり、25〜45重量%が特に好ましい。配合量が20重量%未満ではセット保持性に不十分であり、50重量%を超えて配合するとしなやかさに欠ける。また、融点が90℃を超える油剤を用いた場合は、安定な組成物を得ることが困難であり、毛髪化粧料を製造し難い。
【0008】
本発明の構成要素である成分(B)としては、オリーブ油、ヤシ油、サフラワー油、ヒマシ油、綿実油等の油脂類、流動パラフィン、スクワラン、揮発性イソパラフィン等の炭化水素油類、オレイルアルコール、イソステアリルアルコール等のアルコール類、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等のシリコーン類、ミリスチン酸イソプロピル等のエステル類等が挙げられ、融点が35℃未満の物を選択して用いる。融点が30℃未満の物が特に好ましい。上記の物質はそれぞれ単独で又は2種以上を混合して使用することができ、その配合量としては、1.0〜30重量%であり、5.0〜25重量%が特に好ましい。配合量が1.0重量%未満であると再整髪性に劣り、30重量%を超えるとべたつき感が生じる。また成分(B)の配合量は、成分(A)の配合量に対し等量以下、すなわち(A)と(B)の重量配合量比(A)/(B)が1.0以上であり、1.5以上が特に好ましい。成分(A)との重量配合量比(A)/(B)が1.0未満となる配合量であると、べたつき感が生じる。
【0009】
本発明において、融点とは化粧品原料基準第二版注解(薬事日報社)融点測定法による。基本的には第1法を用いる。但し、試料が主として混合物であって非結晶性、かつ水に不溶性、比重1以下の物については第2法、ワセリン類は第3法を用いる。
【0010】
本発明の構成要素である成分(C)水の配合量としては10〜79重量%であり、20〜70重量%が特に好ましい。10重量%未満であると毛髪にしなやかさを与えにくくなり、79重量%を超えて配合すると、セット保持性が悪くなる。
【0011】
また、本発明の毛髪化粧料は、本発明の効果を損なわない範囲であれば、上記必須成分の他に、界面活性剤、アルコール類、高分子化合物、植物エキス、噴射剤、防腐剤、キレート剤、酸化防止剤、紫外線吸収剤、PH調整剤、色素、香料等を配合することも可能である。
【0012】
本発明の毛髪化粧料は、クリーム状、スティック状、エアゾール状等の形態をとることができ、特に剤型にとらわれない。

BACKGROUND OF THE INVENTION
The present invention relates to a composition to be applied to hair, and more particularly to a hair cosmetic that has no stickiness and has a supple feel, good set retention, and re-styling properties.
[0002]
[Prior art]
Conventionally, liquid cosmetics such as silicone oils, ester oils and hydrocarbon oils have been used by solubilizing, emulsifying and dissolving for the purpose of giving hair a supple feel and excellent gloss. However, oils typified by silicone oil have poor set retention on hair and are insufficient. In order to improve the set retention, adding a large amount of these oils is not satisfactory, such as a sticky feeling and an unnatural luster.
[0003]
Moreover, polymer compounds having various film forming ability are used in hair cosmetics for the purpose of setting hair. In particular, acetic acid amphoteric products of dialkylaminoethyl methacrylate polymers, octyl acrylate acrylate / hydroxypropyl acrylate / butyl aminoethyl methacrylate copolymers, quaternized products of vinylpyrrolidone / dimethylaminoethyl methacrylate, and the like are widely used. However, although these polymer compounds are excellent in set retention, they are stiff, and there is also a drawback that it is difficult to re-hair when the film once formed is broken.
[0004]
In order to solve these drawbacks, hair cosmetics (Japanese Patent Laid-Open No. 2-111711) in which an oil such as silicone is combined with a polymer compound have been proposed. However, it was not satisfactory.
[0005]
[Problems to be solved by the invention]
Accordingly, an object of the present invention is to provide a hair cosmetic that has no stickiness to the hair, has a supple feel, good set retention, and styling.
[0006]
[Means for Solving the Problems]
As a result of diligent research in view of such circumstances, the present inventor does not contain a polymer compound having film-forming ability and a water-soluble polymer having spinnability , and (A) an oil agent 20 having a specific melting point. Containing 50 to 50% by weight, (B) an oil agent having a specific melting point of 1.0 to 30% by weight and (C) 10 to 79% by weight of water, and the weight ratio of component (A) to component (B) It has been found that a hair cosmetic composition having (A) / (B) of 1.0 or more achieves the above object, and has completed the present invention.
That is, the present invention does not contain a polymer compound having film-forming ability and a water-soluble polymer having spinnability, and (A) an oil agent having a melting point of 35 to 90 ° C. and 20 to 50% by weight and (B) a melting point. Containing 1.0 to 30% by weight of an oil whose temperature is less than 35 ° C. and (C) 10 to 79% by weight of water, and the weight ratio (A) / (B) of component (A) and component (B) Is a hair cosmetic, characterized in that it is 1.0 or more.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
Component (A) which is a component of the present invention includes oils and fats such as hardened oil and mole, wax such as beeswax, carnauba wax, candelilla wax, whale wax and lanolin, paraffin wax, microcrystalline wax, ozokerite, Hydrocarbon oils such as petrolatum, higher fatty acids such as stearic acid and myristic acid, higher alcohols such as cetanol and stearyl alcohol, esters such as butyl stearate and cetyl lactate, etc., melting point 35 to 90 ° C. Select and use. The thing whose melting | fusing point is 40 degreeC or more is especially preferable. These substances can be used singly or in combination of two or more. The blending amount thereof is 20 to 50% by weight, and 25 to 45% by weight is particularly preferable. If the blending amount is less than 20% by weight, the set retention is insufficient, and if it exceeds 50% by weight, the flexibility is lacking. Moreover, when the oil agent whose melting | fusing point exceeds 90 degreeC is used, it is difficult to obtain a stable composition and it is difficult to manufacture hair cosmetics.
[0008]
As component (B) which is a constituent element of the present invention, oils and fats such as olive oil, coconut oil, safflower oil, castor oil and cottonseed oil, hydrocarbon oils such as liquid paraffin, squalane and volatile isoparaffin, oleyl alcohol, Examples include alcohols such as isostearyl alcohol, silicones such as dimethylpolysiloxane and methylphenylpolysiloxane, and esters such as isopropyl myristate, and those having a melting point of less than 35 ° C. are selected and used. Those having a melting point of less than 30 ° C. are particularly preferred. The above substances can be used alone or in admixture of two or more, and the blending amount thereof is 1.0 to 30% by weight, particularly preferably 5.0 to 25% by weight. If the blending amount is less than 1.0% by weight, the hair styling property is inferior, and if it exceeds 30% by weight, a sticky feeling is produced. The blending amount of component (B) is equal to or less than the blending amount of component (A), that is, the weight blending ratio (A) / (B) of (A) and (B) is 1.0 or more. 1.5 or more is particularly preferable. If the weight blending ratio (A) / (B) with the component (A) is less than 1.0, a sticky feeling is produced.
[0009]
In this invention, melting | fusing point is based on the cosmetics raw material standard 2nd edition comment (Pharmaceutical Daily) company melting point measuring method. Basically, the first method is used. However, the second method is used for samples that are mainly a mixture and are non-crystalline, insoluble in water and have a specific gravity of 1 or less, and the third method is used for petrolatums.
[0010]
The amount of component (C) water, which is a component of the present invention, is 10 to 79% by weight, and 20 to 70% by weight is particularly preferable. If it is less than 10% by weight, it will be difficult to give the hair suppleness, and if it exceeds 79% by weight, the set retention will be poor.
[0011]
Further, the hair cosmetic composition of the present invention, as long as it does not impair the effects of the present invention, in addition to the above essential components, a surfactant, alcohols, polymers, plant extracts, injection Ysaye, preservatives, It is also possible to blend chelating agents, antioxidants, ultraviolet absorbers, pH adjusting agents, pigments, fragrances and the like.
[0012]

[0013]
【Example】
Hereinafter, the present invention will be described with reference to examples and comparative examples. In addition, this invention is not limited by these.
[0014]
Test methods for set retention and sensory tests shown in Examples and Comparative Examples are as follows. In addition, the compounding quantity of the composition shown in the following table | surfaces is each shown by weight%.
[0015]
(1) Hair-styling retention effect 0.5 g of a hair cosmetic sample is evenly applied to a hair bundle having a length of 15 cm and a weight of 1 g, wound on a rod having a diameter of 2 cm, and left in a constant temperature room at 45 ° C. for 6 hours. , Completely dried. After drying, the rod was removed and the apparent length (L) of the hair bundle was measured. Next, the hair bundle was hung in a constant temperature and humidity chamber at a temperature of 25 ° C. and a humidity of 90%, taken out after 30 minutes, and the apparent length (L 0 ) of the hair bundle was measured again.
[0016]
Hair styling (set) retention was determined by the following equation.
Set retention (%) = (15−L 0 ) ÷ (15−L) × 100
Therefore, the closer this value is to 100, the higher the set retention.
[0017]
The evaluation criteria are as follows.
◎: Very good set retention 80% or more ○: Good set retention 50% or more, less than 80% △: Slightly poor set retention 30% or more, less than 50% ×: Bad set retention 30% or less [0018]
(2) Sensory test Hair conditioning was performed by using 20 hair samples using hair cosmetic samples. After that, the subject himself made a sensory evaluation of non-stickiness, suppleness (non-stiffness), and re-styling. The evaluation criteria are as follows.
[0019]
No stickiness ◎: Very good No more sticky subjects 18 or more ○: Good No sticky subjects 12 or more, less than 18 △: Somewhat bad no stickiness The number of subjects who were 8 or more and less than 12 ×: The number of subjects who answered that there was no bad stickiness <8
Suppleness ◎: Very good The number of subjects who answered that there was no wrinkle 18 or more ○: Good The number of subjects who answered that there was no wrinkle 12 or more, less than 18 people △: Somewhat bad I answered that there was no wrinkle The number of subjects is 8 or more and less than 12 ×: The number of subjects who answered that there is no badness is less than 8
Re-hair styling ◎: Very good The number of subjects who answered that it is easy to re-hair is 18 or more ○: Good The number of subjects who answered that it is easy to re-hair is 12 or more, less than 18 △: Slightly bad The number of subjects who answered that hair styling is easy is 8 or more and less than 12 ×: bad The number of subjects who answered that styling is easy is less than 8
