Description

【００１９】
【表２】

（製法）Ａ相を混合溶解し、Ｂ相に加えて攪拌した。
【００２０】
表１のように、ＭＭＢを２重量％配合しただけでは、透明な組成物を調製することはできない。また、非イオン型界面活性剤のみを配合した場合も同様である。
これに対して、表２のようにＭＭＢと、ＨＬＢが１０〜１３の非イオン型界面活性剤を併用した場合には、透明な組成物が得られ、これらは低温保存後も白濁を生じなかった。そこで、各成分についてさらに検討を行った。
【００２１】
【表３】

（製法）表１に同じ。
【００２２】
表３に示されるように、ＭＭＢが２重量％未満でも特定の非イオン型界面活性剤を併用することにより、製造直後及び低温保存後の透明性が改善される。なお、このような効果を得るためには、ＭＭＢの配合量は組成物中０．１重量％以上であることが好適である。
【００２３】
【表４】

（製法）表１に同じ。
【００２４】
表４に示されるように、非イオン型界面活性剤が油性成分に対して少なすぎると透明性が維持できないことがある。一方、非イオン型界面活性剤を過剰に配合しても効果の増大は望めない。従って、非イオン型界面活性剤の配合量は油性成分に対して０．５〜２倍重量、さらには０．５〜等倍重量であることが好ましい。
【００２５】
【表５】

（製法）Ａ相を混合溶解し、Ｂ相に加えて攪拌した。
【００２６】
表５の非イオン性界面活性剤は、何れも少量のＭＭＢを併用することにより、製造直後、低温保存後ともに透明性の高い組成物を与えた。
【００２７】
【表６】

（製法）表１に同じ。
【００２８】
表６のように、油性成分の少なくとも一部を炭化水素とすることによって、製造直後や低温保存後の透明性をさらに改善することができる。ただし、炭化水素の配合量が多くなるとかえって透明性が低下するので、炭化水素配合量は組成物中０．０１〜２重量％が好適である。
【００２９】
以上のように、本発明によれば、２重量％未満のＭＭＢと、特定のＨＬＢの非イオン型界面活性剤とを併用することにより、透明で、低温保存後の白濁がない水系組成物を得ることができる。また、油性成分の少なくとも一部を炭化水素とすれば、透明安定性をさらに改善することができる。
また、特開平９−２５５９８６においては、溶解性改善にエタノールの配合が有効である旨記載されている。本発明においてもエタノールを配合することは可能であるが、上記のように、特に配合しなくとも低温保存に対して透明安定性の良好な組成物を得ることができる。
【００３０】
本発明の透明水系組成物は、化粧料や医薬品、医薬部外品等に好適である。例えば、化粧水、美容液、芳香用組成物の他、各種液状製剤が挙げられる。なお、本透明水系組成物は、公知の方法により、スプレー、ジェル、ムースなどの剤型とすることも可能である。また、不織布等に含浸させて、シート状製剤とすることも可能である。

Since it will be difficult to solubilize transparently if these oil components are too much, the blending amount is 0.01 to 10% by weight, preferably 0.01 to 5% by weight in the composition.
In the composition of the present invention, when at least a hydrocarbon is blended as an oil component, the transparency can be further improved. In order to obtain such an effect, the hydrocarbon is preferably blended in an amount of 0.01 to 2% by weight in the composition.
[0016]
In the composition of the present invention, the blending amount of the nonionic surfactant is preferably 0.5 to 2 times, more preferably 0.5 to 1 times the weight of the oil component. When the amount of the surfactant is too small, the effect of the present invention cannot be sufficiently obtained, while when the amount is excessively added, the increase in the effect cannot be expected, and the feeling of use may be adversely affected.
The composition of the present invention contains a large amount of water. The blending amount of water is 60% by weight or more, preferably 70% by weight or more because of the relationship with other components.
[0017]
Hereinafter, the present invention will be described with specific examples. The appearance was evaluated immediately after production (25 ° C.) and after storage for 1 week at a low temperature of −10 ° C. with the naked eye, and indicated as transparent ○, translucent Δ, and cloudiness ×.
First, it investigated using the rose type floral-like fragrance | flavor as an oil-based component. Unless otherwise specified, the blending amount is expressed in weight%.
[0018]
[Table 1]

[0019]
[Table 2]

(Production method) Phase A was mixed and dissolved, added to phase B, and stirred.
[0020]
As shown in Table 1, a transparent composition cannot be prepared only by blending 2% by weight of MMB. The same applies when only a nonionic surfactant is blended.
On the other hand, as shown in Table 2, when MMB and a nonionic surfactant having an HLB of 10 to 13 are used in combination, a transparent composition is obtained, which does not cause cloudiness even after low-temperature storage. It was. Therefore, each component was further examined.
[0021]
[Table 3]

(Production method) Same as Table 1.
[0022]
As shown in Table 3, the transparency immediately after production and after low-temperature storage is improved by using a specific nonionic surfactant in combination even when the MMB is less than 2% by weight. In addition, in order to acquire such an effect, it is suitable that the compounding quantity of MMB is 0.1 weight% or more in a composition.
[0023]
[Table 4]

(Production method) Same as Table 1.
[0024]
As shown in Table 4, when the nonionic surfactant is too small relative to the oil component, the transparency may not be maintained. On the other hand, an increase in the effect cannot be expected even if the nonionic surfactant is added excessively. Therefore, the blending amount of the nonionic surfactant is preferably 0.5 to 2 times the weight, more preferably 0.5 to 1 times the weight of the oil component.
[0025]
[Table 5]

(Production method) Phase A was mixed and dissolved, added to phase B, and stirred.
[0026]
All of the nonionic surfactants in Table 5 were used in combination with a small amount of MMB to give a highly transparent composition immediately after production and after low-temperature storage.
[0027]
[Table 6]

(Production method) Same as Table 1.
[0028]
As shown in Table 6, the transparency immediately after production or after low-temperature storage can be further improved by making at least a part of the oil component a hydrocarbon. However, since the transparency is lowered when the amount of the hydrocarbon is increased, the amount of the hydrocarbon is preferably 0.01 to 2% by weight in the composition.
[0029]
As described above, according to the present invention, an aqueous composition that is transparent and free from white turbidity after low-temperature storage can be obtained by using a combination of less than 2% by weight of MMB and a specific nonionic surfactant of HLB. Can be obtained. Further, if at least a part of the oil component is a hydrocarbon, the transparency stability can be further improved.
Japanese Patent Application Laid-Open No. 9-255986 describes that blending of ethanol is effective for improving solubility. In the present invention, it is possible to blend ethanol, but as described above, a composition having good transparency stability against low-temperature storage can be obtained without blending.
[0030]
The transparent aqueous composition of the present invention is suitable for cosmetics, pharmaceuticals, quasi drugs and the like. For example, various liquid preparations may be mentioned in addition to lotions, cosmetic liquids and fragrance compositions. In addition, this transparent water-system composition can also be made into dosage forms, such as a spray, a gel, and a mousse, by a well-known method. Moreover, it can also be impregnated into a nonwoven fabric or the like to form a sheet-form preparation.
