Description

【0001】
【発明の属する技術分野】
本発明は、錠剤や錠菓に配合される滑沢剤、すなわち錠剤及び錠菓用滑沢剤に関する。詳しくは特定の形状及び粒子径を有するショ糖脂肪酸エステルからなる錠剤及び錠菓用滑沢剤に関する。
【0002】
【従来の技術及び発明が解決しようとする課題】
滑沢剤は医薬品のみならず、医薬部外品、食品においても打錠時に必要不可欠な物であるが、錠剤の形が複雑になる程、より多くの滑沢剤を必要とする。それに伴いいかに滑沢剤の添加量を少量にしかつ形状を保つかが問題となってくる。従来、通常の形状の錠剤を作るのに、滑沢剤としてショ糖脂肪酸エステルを1〜5%添加する。しかし、錠剤の形状が複雑になるに伴い従来の形状すなわち球状でないショ糖脂肪酸エステルでは添加量は増加し、添加量の増加に伴ってコスト等の問題あるいは充てん率のバラツキによる製品の重量及び崩壊性の均一化、表面の美しさ等の問題が生じていた。
【0003】
【課題を解決するための手段】
これらの問題を解決する為鋭意検討し次の知見を見出すに致った。従来のショ糖脂肪酸エステルの製法は一度固まり状にした物を粉砕して得られるが、これは形状が球状ではなく、また平均粒子径も大きいものとなっていたため、形状が複雑でかつ打錠しにくい粉体を打錠する時に添加量を増やす必要があった。そこで鋭意検討した結果、ショ糖脂肪酸エステルの形状を球状とし、かつ特定の平均粒子径とすることによって、いかなる形状の打錠物であっても低添加量で滑沢性能を向上できる事を見い出した。
【0004】
すなわち、30μm以下のものが80重量%以上である平均粒子径をもち、かつ形状が球状であるショ糖脂肪酸エステルからなる錠剤及び錠菓用滑沢剤である。
【0005】
【発明の実施の形態】
本発明の滑沢剤に使用するショ糖脂肪酸エステル(以下SEという)は形状として球状のものである。この球状とは楕円形のものから、タマゴ型あるいは真球状のものまでを含んでいる。この球形度は光学顕微鏡で確認できる。更にこの球状SEは平均粒子径30μm以下のものが80重量%以上必要である。このようなSEとした時に、従来になく滑沢性能が向上できる。この粒子径の測定はレーザー式粒度測定機にて測定される。
【0006】
前記SEを構成する脂肪酸は炭素数14〜22で、具体的にはミリスチン酸、パルミチン酸、ステアリン酸、ベヘン酸、アラキジン酸等が挙げられ、2種以上の脂肪酸であってもよい。置換度は1〜5のものが良い。
【0007】
前記したような特定SEを得るための製造法は特に限定されるわけではないが、具体例をあげると噴霧乾燥法が挙げられる。
【0008】
この噴霧乾燥法は、実施例に示されるように35重量%や40重量%というようなSE水溶液を使用し、従来公知の噴霧乾燥条件に従って実施される。乾燥温度は10〜100℃であって、回転円板上に前記水性液を落下させることにより行われる。
【0009】
このような条件のもとで、噴霧乾燥が行われた場合、得られるSEの形状は70重量%以上が球状であって、更に80重量%以上が平均粒子径30μm以下の球状SEが得られる。
【0010】
対象となる錠剤及び錠菓とはビタミン、カルシウム、鉄等を配合した健康食品や、打錠菓子などの食品錠剤等の医薬品等である。
【0011】
これらの錠剤及び錠菓には本発明の滑沢剤が0.2〜10重量%配合される。滑沢性能を損なわない範囲であれば微結晶セルロース、ステアリン酸マグネシウム、合成ケイ酸アルミニウム、脂肪酸モノグリセライドといった従来の滑沢剤も併用できる。

BACKGROUND OF THE INVENTION
The present invention, lubricant is formulated into a tablet or tablet candy, i.e. about tablets agent and tablets菓用lubricants. Specifically, the present invention relates to a tablet and tablet confectionary lubricant comprising a sucrose fatty acid ester having a specific shape and particle size.
[0002]
[Prior art and problems to be solved by the invention]
Lubricants are indispensable not only for pharmaceuticals but also for quasi-drugs and foods at the time of tableting, but the more complex the tablet shape, the more lubricants are required. Along with this, how to reduce the amount of lubricant added and keep the shape becomes a problem. Conventionally, 1-5% of sucrose fatty acid ester is added as a lubricant to produce tablets having a normal shape. However, as the shape of the tablet becomes more complex, the amount of sucrose fatty acid ester that is a conventional shape, that is, a non-spherical sucrose, increases. There have been problems such as uniformity of surface property and surface beauty.
[0003]
[Means for Solving the Problems]
We intensively studied to solve these problems and found the following knowledge. The conventional method for producing sucrose fatty acid ester is obtained by pulverizing a once-solidified product, but this is not spherical and the average particle size is large, so the shape is complicated and tableting It was necessary to increase the amount of addition when tableting difficult to powder. As a result of intensive investigations, it was found that the sucrose fatty acid ester shape can be made spherical and have a specific average particle size, so that it is possible to improve the lubrication performance with a low addition amount even for tablets of any shape. It was.
[0004]
That is, it is a tablet and tablet confectionary lubricant made of a sucrose fatty acid ester having an average particle diameter of 80% by weight or more with a particle size of 30 μm or less and a spherical shape.
[0005]
DETAILED DESCRIPTION OF THE INVENTION
The sucrose fatty acid ester (hereinafter referred to as SE) used in the lubricant of the present invention is spherical in shape. The spherical shape includes an elliptical shape, an egg shape or a true spherical shape. This sphericity can be confirmed with an optical microscope. Further, the spherical SE must have an average particle size of 30 μm or less and 80% by weight or more. When such SE is used, the lubrication performance can be improved compared to the conventional case. The particle size is measured with a laser particle size measuring machine.
[0006]
The fatty acid constituting the SE has 14 to 22 carbon atoms, and specifically includes myristic acid, palmitic acid, stearic acid, behenic acid, arachidic acid and the like, and may be two or more fatty acids. The degree of substitution is preferably 1-5.
[0007]
The production method for obtaining the specific SE as described above is not particularly limited, but a specific example includes a spray drying method.
[0008]
This spray drying method is carried out according to conventionally known spray drying conditions using an SE aqueous solution of 35% by weight or 40% by weight as shown in Examples. Drying temperature is 10-100 degreeC, Comprising: It is performed by dropping the said aqueous liquid on a rotating disc.
[0009]
When spray drying is performed under such conditions, the SE shape obtained is spherical in which 70% by weight or more is spherical and 80% by weight or more has a mean particle diameter of 30 μm or less. .
[0010]
The target tablets and tablet confectionery are health foods containing vitamins, calcium, iron and the like, and pharmaceuticals such as food tablets such as tablet confectionery.
[0011]
These tablets and tablet confectionery contain 0.2 to 10% by weight of the lubricant of the present invention. Conventional lubricants such as microcrystalline cellulose, magnesium stearate, synthetic aluminum silicate, and fatty acid monoglyceride can be used in combination as long as the lubricating performance is not impaired.

And spray drying. When the particle size of the obtained dried product was measured with a laser type particle size measuring instrument 9320-X100 (manufactured by Microtrac), the average particle size was 95% or less. Moreover, as a result of observing the particles with an optical microscope (100 times), 90% by weight or more was spherical. The obtained lubricant was added to granulated sugar at 0.3% by weight, and a tableted product was obtained under the following tableting conditions.
[0013]
Example 2
1.0% by weight of the dried product obtained in Example 1 as a lubricant was added to powdered sorbite to obtain a tableted product. The tableting conditions are as follows.

[0015]
○ Evaluation method Lubricating performance was evaluated by determining the effective tableting rate by the following formula.
