Description
【発明の詳細な説明】 ［産業上の利用分野］ 本発明は、無孔質球状シリカを配合した化粧品に関す
るものである。Description: TECHNICAL FIELD The present invention relates to cosmetics containing non-porous spherical silica.
［従来の技術］ 従来、メーキャップ用化粧品において伸展性や付着性
を向上させることを目的として、微細な球状無水ケイ酸
（特開昭54−55739）や、球状シリカゲル（特公昭62−1
4525）を配合することが提案されている。しかし、これ
らはいずれも多孔質で高い吸油性を有するために、他に
配合される油脂や有効成分を吸収吸着してしまう。この
ため、油脂等の配合量が多くなってしまう問題点があ
る。[Prior Art] Conventionally, in order to improve the extensibility and adhesiveness of makeup cosmetics, fine spherical silicic anhydride (JP-A-54-55739) and spherical silica gel (JP-B-62-1) have been used.
4525) has been proposed. However, all of them are porous and have high oil absorbing properties, so that they absorb and adsorb other fats and oils and active ingredients. For this reason, there is a problem that the amount of fats and oils is increased.
一方、多孔質のシリカゲルを、電気炉やガス炉で焼成
して、無孔質のシリカを製造する方法が知られている。
しかし、このような方法で製造したシリカは、焼成中に
粒子同士が融着焼結を起こし、再分散させるには粉砕お
よび分級操作が必要であった。また、粒子の形状も概ね
球状であるがいびつな形状のものが少なくないという問
題点がある。このため、特に化粧品の用途には不適当で
あった。On the other hand, there has been known a method of producing porous silica by firing porous silica gel in an electric furnace or a gas furnace.
However, silica produced by such a method causes fusion sintering of the particles during firing, and requires pulverization and classification operations for redispersion. In addition, the shape of the particles is generally spherical, but there is a problem that there are many irregular shapes. For this reason, it was unsuitable especially for use in cosmetics.
［発明が解決しようとする課題］ 本発明の目的は、軟らかく伸びが良好な化粧品を提供
することである。[Problem to be Solved by the Invention] An object of the present invention is to provide a cosmetic product that is soft and has good elongation.
［課題を解決するための手段］ 本発明は、多孔質シリカゲルを高温の気体中に分散さ
せて焼成し無孔質化することにより得られた単分散性の
無孔質球状シリカを３〜70重量％配合したことを特徴と
する化粧品を提供するものである。[Means for Solving the Problems] The present invention provides a monodisperse nonporous spherical silica obtained by dispersing porous silica gel in a high-temperature gas, firing and making it nonporous, from 3 to 70%. An object of the present invention is to provide a cosmetic product characterized by being blended by weight.
本発明の化粧品に配合するシリカは、気体中に分散さ
せてシリカゲルを焼成することにより得たものである。
このため、シリカゲル同士が融着して二次粒子を形成し
ないので、単分散性の優れた無孔質シリカが得られる。
また、ここで得られるシリカ粒子の形状は、焼成が固体
と接触しない状態で行われるので真球度の高い球状体が
得られる。焼成の方法としては、種々採用可能である
が、例えばシリカゲルを空気輸送によって高温気体中に
導入する方法等が挙げられる。The silica compounded in the cosmetic of the present invention is obtained by dispersing in a gas and firing silica gel.
For this reason, since the silica gels do not fuse with each other to form secondary particles, nonporous silica having excellent monodispersity can be obtained.
In addition, the shape of the silica particles obtained here is a sphere having a high sphericity because the calcination is performed in a state of not contacting the solid. Various firing methods can be employed. For example, a method of introducing silica gel into a high-temperature gas by pneumatic transportation can be used.
高温気体としては、1000℃以上の温度が好ましい。10
00℃未満の場合は、無孔質化が進行しにくく、目的の球
状無孔質シリカが得られない場合があるので好ましくな
い。また、気体の温度が2000℃を超えると、シリカの結
晶化が進行するおそれがあるので好ましくない。As the high-temperature gas, a temperature of 1000 ° C. or more is preferable. Ten
If the temperature is lower than 00 ° C., it is not preferable because the formation of nonporous hardly proceeds, and the desired spherical nonporous silica may not be obtained. On the other hand, if the temperature of the gas exceeds 2000 ° C., crystallization of silica may proceed, which is not preferable.
本発明の化粧品に配合するシリカにおいて、焼成処理
をする原料多孔質シリカゲルの形状は、特に限定されな
いが、粒径１〜100μｍ程度の球状のシリカゲルを使用
する場合は、容易に球状の無孔質シリカ粒子を得ること
ができるので好ましい。また、原料多孔質シリカゲルと
して、粒径の大きなシリカゲルを破砕して得られる不定
形のシリカゲルも、好適に用いることができる。In the silica to be incorporated into the cosmetic of the present invention, the shape of the raw material porous silica gel to be subjected to the calcination treatment is not particularly limited. It is preferable because silica particles can be obtained. As the raw material porous silica gel, amorphous silica gel obtained by crushing silica gel having a large particle diameter can also be suitably used.
本発明の化粧品において、無孔質シリカの配合割合
は、３〜70重量％である。配合量が３重量％未満の場合
は、十分な伸展性が得られない。また、70重量％を超え
る場合は、化粧品が固くなりすぎる。In the cosmetic of the present invention, the mixing ratio of the nonporous silica is 3 to 70% by weight. If the amount is less than 3% by weight, sufficient extensibility cannot be obtained. On the other hand, if it exceeds 70% by weight, the cosmetics become too hard.
無孔質シリカの平均粒径は、１〜20μｍであることが
好ましい。平均粒径が１μｍ未満の場合は、十分な伸展
性が得られないので好ましくない。平均粒径が20μｍを
超える場合は、ざらついた感覚を与えるので好ましくな
い。平均粒径が３〜10μｍである場合は、さらに好まし
い。The average particle size of the nonporous silica is preferably 1 to 20 μm. If the average particle size is less than 1 μm, it is not preferable because sufficient extensibility cannot be obtained. When the average particle size exceeds 20 μm, it is not preferable because it gives a rough feeling. It is more preferable that the average particle size is 3 to 10 μm.
無孔質シリカの吸油量は、JIS K5101の測定法で80ml/
100g以下であることが好ましい。吸油量が80ml/100gを
超える場合は、化粧品中に油分を多量に配合する必要が
あるので好ましくない。より好ましい吸油量は40ml/100
g以下である。The oil absorption of non-porous silica is 80 ml /
It is preferably 100 g or less. If the oil absorption exceeds 80 ml / 100 g, it is not preferable because a large amount of oil must be incorporated into cosmetics. More preferred oil absorption is 40ml / 100
g or less.

About half of the liquid paraffin and sorbitan monooleate are added to the mixture, and the mixture is uniformly dispersed with a homomixer. The remaining components are heated and melted, and mixed well. This was poured into a container and solidified by cooling to obtain a makeup cosmetic.

す。評価項目は、１）化粧品を手に取るときの固さ（5:
軟らかい〜1:固い）、２）化粧品の伸び（5:良好〜1:不
良）、３）塗布時の油っぽさ（5:ある〜1:ない）、４）
塗布後の透明感（5:良好〜1:不良）である。The three makeup cosmetics thus obtained were used by cosmetics passengers (seven women), and the following points were evaluated relative to each other on a five-point scale. Table 2 shows the results. Evaluation items were: 1) Hardness when picking up cosmetics (5:
Soft ~ 1: hard) 2) elongation of cosmetics (5: good ~ 1: bad) 3) oiliness at application (5: 1 ~ 1: no) 4)
Transparency after application (5: good to 1: bad).
表２より、実施例１の化粧品は、軟らかく伸びが優れ
ていることがわかる。比較例１の化粧品は、使用中の油
っぽさはないが、逆にやや粉っぽい感じがするという意
見があった。これは、配合したシリカゲルの吸油量が大
きいために、配合した油分が吸収されているためと考え
られる。 Table 2 shows that the cosmetic of Example 1 is soft and has excellent elongation. There was an opinion that the cosmetic of Comparative Example 1 did not have oiliness during use, but felt somewhat powdery. This is presumably because the blended silica gel had a large oil absorption and the blended oil was absorbed.
［発明の効果］ 本発明の化粧品に配合されるシリカは、粒子の形状が
