Import Ethyl Cellulose(Ec) — Buy in wholesale FOB from Supplier in China

Ethyl Cellulose(EC) is a white to light tan, free-flowing powder with CAS number 9004-57-3, derived from the etherification of cellulose with ethyl groups. It is insoluble in water but dissolves readily in alcohols, esters, and other organic solvents. The material functions as a binder, film former, and thickener in pharmaceutical and cosmetic formulations, with a typical substitution degree of 45-49% ethoxy groups, as commonly observed in industrial-grade EC.

This product is manufactured to meet standard pharmaceutical and cosmetic industry requirements for purity and flowability. The powder has a bulk density of approximately 0.35-0.45 g/cm³ and a particle size distribution typical for direct compression applications. It does not contain residual solvents above acceptable limits per ICH Q3C guidelines. Unlike lower-grade EC, this material shows consistent viscosity in ethanol solutions, making it suitable for controlled-release tablet coatings and topical formulations requiring uniform film integrity.

Buyers include pharmaceutical tablet manufacturers, cosmetic formulators, and specialty chemical distributors sourcing sustained-release excipients. It is typically packed in 25kg multi-wall paper bags with inner polyethylene lining, sealed under nitrogen to prevent moisture absorption. Trade terms are generally FOB Cangzhou Port, with MOQ starting at 500kg. Lead time is 15-20 days after order confirmation. Buyers should request a Certificate of Analysis for ethoxy content, viscosity, and moisture levels before shipment.

Anxin Cellulose Co., Ltd. operates from Lingang Chemical Park in Cangzhou, Hebei Province, China, with a registered address confirming its physical presence in a dedicated industrial zone. The company is listed with harbor-tier trust verification, indicating documented business registration and facility inspection. There is no public data on production volume, workforce size, or export history. The listing confirms active supply of Ethyl Cellulose but provides no evidence of certifications such as USP, EP, or ISO.

The supplier does not claim ISO certification, GMP compliance, or third-party audit results. Response metrics show no recorded replies to buyer inquiries, which may indicate limited customer service capacity. Buyers should treat this as a direct manufacturer without verified quality systems, and request independent lab reports for each batch. The absence of client names or export records suggests the company serves niche or regional markets rather than global pharmaceutical supply chains.
