The application of cellulose ether is very extensive, and the overall development of the national economy will directly drive the development of the cellulose ether industry. At present, the application of cellulose ether in China is mainly concentrated in industries such as building materials, oil drilling and medicine. With the application and promotion of cellulose ether in other fields, the demand for cellulose ether in downstream industries will grow rapidly.

In addition, the country’s increased investment in fixed asset construction and energy development, as well as the country’s urbanization construction, and the increase in residents’ consumption in housing, health and other fields, will all have a positive impact on cellulose ether through the conduction of construction materials, oil drilling and pharmaceutical industries. Industry growth produces an indirect pull.

HPMC products are mainly used in various fields of the national economy in the form of additives, so HPMC has the characteristics of wide consumption and scattered consumption, and downstream end users mainly purchase in small quantities. Based on the characteristics of scattered end users in the market, HPMC product sales mostly adopt the dealer model.

Nonionic cellulose ethers are widely used in the pharmaceutical industry as pharmaceutical excipients, such as thickeners, dispersants, emulsifiers and film-forming agents. It is used for film coating and adhesive on tablet medicine, and it can also be used for suspension, ophthalmic preparation, sustained and controlled release matrix and floating tablet, etc. Because pharmaceutical grade cellulose ether has extremely strict requirements on product purity and viscosity, the production process is relatively complicated and there are many washing procedures. Compared with other grades of cellulose ether products, the collection rate of finished products is low, the production cost is high, and the added value of the product is relatively high. high.

At present, foreign pharmaceutical excipients account for 10-20% of the output value of the entire pharmaceutical preparations. Since my country’s pharmaceutical excipients started late and the overall level is low, domestic pharmaceutical excipients account for a relatively low proportion of the entire drug, about 2-3%. Pharmaceutical excipients are mainly used in preparation products such as chemical preparations, Chinese patent medicines and biochemical products. From 2008 to 2012, the total output value of pharmaceuticals was 417.816 billion yuan, 503.315 billion yuan, 628.713 billion yuan, 887.957 billion yuan and 1,053.953billion yuan respectively1. According to the proportion of my country’s pharmaceutical excipients accounting for 2% of the total output value of pharmaceutical preparations, the total output value of domestic pharmaceutical excipients from 2008 to 2012 was about 8 billion yuan, 10 billion yuan, 12.5 billion yuan, 18 billion yuan and 21 billion yuan .

During the “Twelfth Five-Year Plan” period, the Ministry of Science and Technology included key technologies for the development of new pharmaceutical excipients as research topics. In the “12th Five-Year Development Plan of the Pharmaceutical Industry” issued by the Ministry of Industry and Information Technology, strengthening the development and application of new pharmaceutical excipients and packaging materials is listed as a key area for the development of the pharmaceutical industry. In accordance with the goal of an average annual growth rate of 20% in the total output value of the pharmaceutical industry in the “Twelfth Five-Year Plan” of the Ministry of Industry and Information Technology, the market size of pharmaceutical excipients will grow rapidly in the future, and at the same time promote the growth of the pharmaceutical grade HPMC market.
