Embodiment

[0015] Embodiment: a capsule release agent, which is prepared by adding the following components into every 1500ml of liquid paraffin: 250g of calcium stearate, 250g of stearic acid, and 100g of lecithin.

[0016] The preparation method of capsule release agent of the present invention, comprises the steps:

[0017] (1), pour 1500ml liquid paraffin into a 3000ml beaker, and place it on an electric stove for heating;

[0018] (2), add calcium stearate 250g earlier in heating process, make it dissolve completely;

[0019] (3), when the temperature reaches 80°C, under constant stirring, start to add 250g of stearic acid to make it completely dissolved, and the temperature of the stearic acid dissolution process is controlled between 80°C-100°C;

[0020] (4), put the beaker containing the above solution into a 90°C constant temperature water bath, add 100 g of lecithin in the beaker under constant stirring, and the whole stirring process takes 2 hours to completely dissolve the l...

Abstract

The invention discloses a capsule mold release agent and a preparation method thereof. The mold release agent is prepared by adding components, namely 230 to 270g of calcium stearate, 230 to 270g of stearic acid and 90 to 110g of lecithin into every 1,450 to 1,550ml of liquid paraffin. The preparation method comprises the following steps of: sequentially adding the calcium stearate, the stearic acid and the lecithin in the process of heating the liquid paraffin; and continuously stirring to obtain the mold release agent. The mold release agent is smectic, can be uniformly coated on an oil coating pipe felt of a capsule production line during use, and has a better effect after being coated once every 12 hours. Due to the adoption of the mold release agent, the transparency and the luminance brightness of a capsule can be greatly improved, so that the aesthetic appearance of the capsule is improved, and product yield can be improved; and the preparation method has a simple process, is easy to operate and low in cost, is beneficial to large-scale production and makes cost reduced.

Description

technical field [0001] The invention relates to a capsule release agent and a preparation method, which are applied to the production of transparent hollow capsules in the pharmaceutical industry. Background technique [0002] Capsules are one of the oldest dosage forms of medicines. They originated in ancient Egypt and account for about one-third of all dosage forms in the pharmaceutical industry. Therefore, the hollow capsules used in capsules are one of the important packaging materials in the pharmaceutical industry. [0003] Hollow capsules can be divided into two types: transparent and opaque according to their appearance. During the production process, a mold release agent needs to be applied so that the capsules can be detached from the mold smoothly. Generally, the release agent is light yellow liquid, which can be used in the production of opaque capsules. And if the production of transparent capsules uses this light yellow release agent, the transparency and brig...
