Feature Story

An Expanding World of Solutions Through Science and Polymer Technology

When you choose to work with The Dow Chemical Company, you choose an excipient solutions provider, not just a source of excipients. With Dow, you have access to technologies, experience, and a range of excipient products that can help your project move faster toward success.

Dow’s Expertise Can Speed Development and Approvals

The Water Soluble Polymers business group of The Dow Chemical Company offers an unusually broad body of excipient knowledge. We have a diverse, experienced team of individuals who are actively engaged in product development, technology development, and pharmaceutical applications support. So when you need help with technical issues involving excipient behavior, product selection, and formulation optimization, our organization can respond in surprisingly powerful ways.

Broad Experience with Many Excipient Technologies

In our work supporting METHOCEL*, ETHOCEL*, and POLYOX™ excipients, The Dow Chemical Company has conducted in-depth studies of excipient behavior in a wide variety of pharmaceutical systems and processing environments. The many technologies in which we’ve done pioneering work include:

Granulation Processing Technologies

Fluid bed granulation
Low shear granulation
High shear granulation
Roller compaction granulation
Foam binder granulation

Tablet Coating Technologies

Aqueous tablet coating
Solvent-based tablet coating
Compression coating

Controlled Release Technologies

Controlled release matrix systems
Controlled release coatings

Other Excipient Technologies

Hot melt extrusion
Mucosal bioadhesion
Immediate release systems
Direct compression technologies

Three Excipient Polymer Choices to Cover a Wide Range of Formulation Variables

Our excipient line includes METHOCEL Premium hypromellose and methylcellulose used in tablet coating, granulation, and controlled release; ETHOCEL Premium ethylcellulose used in tablet coating, direct compression binding, and controlled release; and POLYOX Water-Soluble Resins NF Grade used in controlled release, granulation, and mucosal bioadhesives. Within those product families are many variations on molecular weight and molecular substitution that allow a broad range of functional properties in formulation systems.
