Zhejiang Haishen New Materials Steps Up R&D of Pharmaceutical-Grade Cellulose to Empower High-Quality Development of the Biopharmaceutical Industry

With the further advancement of the consistency evaluation work in China's pharmaceutical industry and the accelerated R&D of innovative preparations, the market demand for high-quality pharmaceutical-grade cellulose has been surging. Against this backdrop, relying on over 30 years of accumulated experience in cellulose R&D and production, Zhejiang Haishen New Materials gives full play to its technical advantages as a participating unit in formulating industry standards. It has targeted and overcome multiple technical difficulties in the production of pharmaceutical-grade cellulose, and successfully built a product system covering multiple categories such as hydroxypropyl methylcellulose (HPMC) and methylcellulose (MC).

Zhejiang Haishen's pharmaceutical-grade cellulose products boast three core strengths.

First, the quality control of hydroxypropyl methylcellulose (HPMC) is strict and precise. The product complies with multiple standards including the Chinese Pharmacopoeia, United States Pharmacopeia, and European Pharmacopoeia. It features excellent biocompatibility and safety, and is suitable for various dosage forms such as tablets, capsules, transparent soft capsules, eye drops, and topical gels. With strong adaptability and outstanding processing performance, it is an indispensable and important pharmaceutical excipient in the modern pharmaceutical industry.

Second, the technology and processes are advanced and mature. Relying on the scientific research strength of the provincial-level R&D center, the enterprise has optimized and upgraded its production processes and adopted a green and low-carbon production technology path. While improving product performance, it has achieved energy conservation and environmental protection in the production process, which is in line with the national "dual carbon" strategy and the development plan of the bioeconomy.

Third, mEthyl Cellulose (MC) is a safe, non-toxic non-ionic cellulose ether with excellent thickening, film-forming, moisturizing, and emulsifying properties. It is widely used in pharmaceuticals, food, daily chemicals, building materials, and other fields. In pharmacy, it can be used as a tablet binder and coating material to enhance stability and controlled-release effects; in other industries, it is used to improve product texture and processing performance. MC has excellent thermal gel properties and meets the pharmacopoeia standards of many countries, making it a highly functional and widely applicable polymer excipient.

At present, China's pharmaceutical excipient industry is in a critical transition period from "basic guarantee" to "high-end upgrading". Relying on over 30 years of technical accumulation and rigorous quality control, Zhejiang Haishen has launched pharmaceutical-grade cellulose products that precisely meet market demands. The launch of these products will not only further enhance the enterprise's core competitiveness, but also provide strong support for the quality upgrading and import substitution of the domestic pharmaceutical excipient industry, propelling the high-quality development of China's pharmaceutical industry to a new level.

Zhejiang Haishen has established a professional sales and technical service team for its pharmaceutical-grade cellulose products, which can provide customers with full-chain services ranging from product selection and technical consultation to customized R&D, helping them improve the efficiency of preparation R&D and product quality.
