Water-soluble sodium carboxymethyl cellulose, methyl cellulose, hydroxypropyl methyl cellulose, hydroxypropyl cellulose, hydroxyethyl cellulose and oil-soluble ethyl cellulose are all used as Adhesives, disintegrants, sustained and controlled release materials for oral preparations, coating film-forming agents, capsule materials and suspending agents are used in pharmaceutical excipients. Looking at the world, several foreign multinational companies (Shin-Etsu Japan, Dow Wolfe and Ashland Cross Dragon) have realized the huge future market of pharmaceutical cellulose in China, either increasing production or merging, and have increased their efforts in this field. application input within. Dow Wolfe announced that it will strengthen its focus on the formulation, ingredients and demand of the Chinese pharmaceutical preparation market, and its applied research will also strive to get closer to the market. Dow Chemical Wolff Cellulose Division and Colorcon Corporation of the United States have established a sustained and controlled release formulation alliance on a global scale, with more than 1,200 employees in 9 cities, 15 asset institutions and 6 GMP companies, a large number of Applied research professionals serve clients in approximately 160 countries. Ashland has production bases in Beijing, Tianjin, Shanghai, Nanjing, Changzhou, Kunshan and Jiangmen, and has invested in three technical research centers in Shanghai and Nanjing.

According to statistics from the website of China Cellulose Association, in 2017, the domestic production of cellulose ether was 373,000 tons, and the sales volume was 360,000 tons. In 2017, the actual sales volume of ionic CMC was 234,000 tons, an increase of 18.61% year-on-year, and the sales volume of non-ionic CMC was 126,000 tons, an increase of 8.2% year-on-year. In addition to HPMC (building material grade), non-ionic products, HPMC (pharmaceutical grade), HPMC (food grade), HEC, HPC, MC, HEMC, etc. have bucked the trend and their production and sales have continued to increase. Domestic cellulose ether has grown rapidly for more than ten years, and its output has become the first in the world. However, the products of most cellulose ether companies are mainly used in the middle and low-end fields of the industry, and the added value is not high.

At present, most domestic cellulose ether enterprises are in the critical period of transformation and upgrading. They should continue to increase product research and development efforts, continuously enrich product varieties, make full use of China, the world’s largest market, and increase efforts to develop foreign markets, so that enterprises can quickly Complete the transformation and upgrading, enter the middle and high-end field of the industry, and achieve benign and green development.
