1. plant capsules main ingredients for the medicine hydroxypropyl methyl cellulose (HPMC), namely 2-hydroxypropyl methyl cellulose. Natural polymer cellulose is the most abundant natural resources, HPMC is usually short cotton wool or wood pulp as raw material, made by etherification. 2. gelatin capsules main ingredients include high quality gelatin and gelatin derived from animal collagen in the skin, muscles and bones, from animal tissue or partially hydrolyzed collagen protein in the epidermis.
2. gelatin capsules main ingredients include high quality gelatin and gelatin derived from animal collagen in the skin, muscles and bones, from animal tissue or partially hydrolyzed collagen protein in the epidermis. 2 method for the determination of capsules and gelatin capsules capsules traits and characters the same gelatin capsules. Capsule plant raw material for hydroxypropyl methyl cellulose, plant identification and identify different gelatin capsules capsule. Identification test plant capsules according to! People's Republic of China 2005 version ∀ identification method of hydroxypropyl methyl cellulose, and drafting capsules features. Plant inspection and gelatin capsules capsule inspection project is basically the same, capsules weight loss on drying criteria for 2%~7%, loss on drying criteria for 12.5%~17.5% gelatin capsule, this is due to the loss on drying of hydroxypropyl methyl cellulose #5%
Capsules of this standard for the 2%~7%.
Hollow gelatin capsules capsules compared with the traditional wide adaptability and Crosslinking reaction of risk-free and the advantages of high stability, release rate is relatively stable, individual differences, and survive after disintegrating in the human body and excreted with feces. In terms of storage, and after a lot of testing in low humidity conditions hardly friability, shell characters remain stable under high humidity, extreme capsule indicators under the storage conditions are not affected. Gelatin capsules capsule adhesion in high humidity conditions, water hardening under low humidity conditions or fragility, the storage temperature and humidity dependent and packaging materials.
