The pharmaceutical industry is constantly seeking methods to increase manufacturing efficiency and reduce environmental impact. NINGBO INNO PHARMCHEM CO.,LTD. is at the forefront of this innovation with its specialized Ethyl Cellulose (EC) grades, designed for solvent-less dry powder layering processes. This advanced technique leverages EC to achieve faster coating times, reduced solvent usage, and improved sustainability.

Traditional spray-coating methods for Ethyl Cellulose often involve dissolving the polymer in organic solvents, which presents environmental, safety, and cost challenges. While aqueous dispersions offer an alternative, they typically require extended drying and curing times. Dry powder coating, however, revolutionizes this by applying the polymer directly from a dry state, significantly streamlining the process.

Our high-productivity (HP) grades of Ethyl Cellulose are specifically engineered for dry powder layering. In this method, substrates are wetted with a tacking agent, and then the dry EC powder is applied. The plasticizer in the tacking agent facilitates particle fusion during a subsequent curing step, creating a robust film without the need for solvents or extensive drying. This process can dramatically reduce total production time, potentially by 40% to 70% compared to conventional methods.

The advantages of using NINGBO INNO PHARMCHEM CO.,LTD.'s Ethyl Cellulose in dry powder coating are manifold. Firstly, it eliminates the need for organic solvents, contributing to a safer and more environmentally friendly manufacturing process. Secondly, the significantly reduced processing times translate into lower energy consumption and higher throughput, offering substantial cost savings. This approach is particularly beneficial for applications requiring ethyl cellulose for controlled-release coatings or taste masking, where efficiency is key.

Moreover, the dry powder layering technique, when used with our precisely milled Ethyl Cellulose particles, ensures efficient particle packing and improved film formation. This results in stable, reproducible drug release profiles and effective taste-masking, comparable to or even exceeding those achieved with traditional methods. The ability to perform drug layering, polymer coating, and film curing within a single piece of equipment further enhances process efficiency.

NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to pushing the boundaries of pharmaceutical manufacturing through innovative excipient solutions. Our Ethyl Cellulose in dry powder coating technology represents a significant leap forward in efficiency, sustainability, and performance. We invite manufacturers to explore this advanced approach and partner with us to unlock the full potential of solvent-less coating technologies.
