Viatel™ Ultrapure high-purity bioresorbable polymers for long-acting injectables and implants offer improved stability and achieve longer, more consistent drug release profiles; they are better suited for sensitive drug compounds in long-acting injectables and implants (LAII).
Removing residual monomer reduces acidic equivalents and results in a more consistent rate of water uptake and degradation kinetics. This means more reproducible performance while also creating a more neutral pH environment. Viatel™ Ultrapure polymers leverage a proprietary purification process that reduces total residual monomer content specifications to below 0.5% with typical batch results of approximately 0.1%. Furthermore, these polymers are pre-filtered during the purification process to ensure exceptional quality.
These low-monomer products are available as GMP grades across the Viatel™ platform and provide formulators greater versatility when solving challenging formulation problems.
Viatel™ Ultrapure polymers are the result of Ashland’s commitment to continuous improvement in response to customer needs.

bioresorbable polymers
A scalable technology platform with multiple applications, bioresorbable polymers serve as a vital component to long-acting injectables and provide a controlled release matrix to address chronic disease, patient compliance, and animal health.
For advanced drug delivery, bioresorbable polymers serve as a carrier that improves the delivery of mRNA to cells, and when it comes to medical devices and regenerative medicine, bioresorbable polymers function as degradable devices and fillers for a wider range of dermal fillers, sutures, screws vital to surgical procedures in every market of the world.
The platform can best be seen by visiting Ashland’s newly launched viatel™ ultrapure bioresorbable polymers.
Ashland has made a major capacity investment for bioresorbable polymers.
