Problems solved by technology

[0005] Although gelatin has good properties in the preparation of hard capsules, gelatin as a heterologous protein may be antigenic
For example, imported bovine-derived gelatin materials may contain prions, and soft capsules made from them may cause the spread of mad cow disease
And gelatin enteric-coated hard capsules have other defects, such as its tolerance to temperature and humidity is relatively strict, so its application is limited; and gelatin enteric-coated hard capsules can only swell in cold water and cannot be dissolved; The hard capsule shell is easy to deform when exposed to high humidity and heat, and it is easy to become brittle under low temperature and low water content conditions and cannot be filled with aldehyde drugs; in addition, its transparency is not satisfactory

preparation example Construction

[0143] The preparation method of the non-gelatin enteric hard capsule shell of the present invention can be carried out on the existing equipment for preparing the gelatin hard capsule shell. Under the condition that no additional equipment is required, the required non-gelatin enteric-coated hard capsule shell can be produced by adjusting the parameters such as drying temperature, humidity, coating film thickness, operating speed, and mold size according to the formula.

[0144] Compared with the prior art, the main advantages of the present invention are:

[0145] (1) The colloid material used in the preparation of the enteric-coated capsule shell is mainly hydrophilic non-gelatin colloid, and does not contain animal protein and fat, thereby avoiding possible pollution caused by animal protein.

[0146] (2) Optionally add plasticizers listed in the present invention.

[0147] (3) The hydrophilic non-gelatin gel is easy to dissolve, which can save the necessary water absorpt...

Abstract

The invention provides a composition used for preparing a non-gelatin enteric hard capsule shell material. The composition contains non-gelatin hydrophilic jellies, an enteric type material, a pH conditioning agent, water and optional coagulant aid, plasticizer and adhesive, and does not contain any organic solvent basically. The invention also discloses a method for producing the enteric hard capsule shell material. The composition does not contain the organic solvent basically, and the enteric hard capsule shell has the advantages of good mouthfeel, high clarity, fast capsule cracking and reduced requirement on storage condition of the capsule.

Description

technical field [0001] The invention relates to the field of materials, in particular to the components and production method of non-gelatin enteric hard capsule shells. Background technique [0002] At present, enteric-coated materials need to be used in the preparation of the capsule shell of enteric-coated hard capsules. Examples of enteric materials are shellac, polyvinyl acetate phthalate, acrylic resins, cellulose derivatives (examples of said cellulose derivatives are: cellulose acetate phthalate, 1,2 , cellulose acetate 4-benzenetricarboxylate, hydroxypropylmethylcellulose phthalate, hydroxypropylmethylcellulose 1,2,4-benzenetricarboxylate, cellulose acetate succinate and hydroxypropyl acetate succinate base methyl cellulose), etc. [0003] The above-mentioned enteric-coated hard capsules using enteric-coated materials all require a large amount of organic solvents, so fires and explosions are likely to occur. In addition, the speed of its rupture and complete dis...
