Description

Poly(caprolactone) Triol

Poly(caprolactone) triol is a pharmaceutical-grade, biodegradable trifunctional polyester used as a versatile excipient and polymeric precursor for biomedical, controlled-release, and implantable drug delivery systems. Its tri-hydroxyl functionality enables advanced crosslinking and copolymerization, supporting the creation of highly tunable, bioresorbable scaffolds and extended-release drug matrices. It

• Is a high-purity trifunctional aliphatic polyester with three terminal hydroxyl groups
• Enables crosslinking, network formation, and hydrolytically degradable polymer architectures
• Is suitable for injectable depots, implantables, wound healing scaffolds, and regenerative medicine applications
• Biodegrades hydrolytically into non-toxic metabolites

Poly(caprolactone) triol is synthesized via ring-opening polymerization of ε-caprolactone using tri-functional initiators, resulting in highly branched, terminal hydroxyl-functional polymers. This allows for flexible chemical derivatization, crosslinked network formation, and incorporation into advanced hydrogel, polyurethane, or composite biomaterials tailored for controlled degradation and mechanical strength.

In pharmaceutical controlled-release formulations, Poly(caprolactone) triol enables the production of injectable microspheres, long-acting implants, and depot systems that release therapeutic agents over extended periods while minimizing burst release. Its slow, predictable degradation supports consistent drug release for months post-administration.

In regenerative medicine and biomedical device fabrication, it serves as a scaffold precursor for soft tissue engineering, cartilage repair, bone regeneration, and bioresorbable wound healing matrices where tailored porosity and degradation timelines are critical for tissue integration and healing.

Procurement teams and formulators looking to purchase Poly(caprolactone) triol benefit from CarboMer’s strict molecular weight control, narrow polydispersity, validated manufacturing, and full regulatory documentation for global submissions.

Material is packaged in sealed, moisture-controlled, tamper-evident containers to ensure storage stability and product integrity. Minimum order quantities (MOQ), lead times, and complete technical data packages are available for clinical development and commercial manufacturing.

Each lot undergoes validated analytical testing for hydroxyl functionality, molecular weight, residual monomers, heavy metals, and microbial limits to ensure reproducibility and compliance with regulatory standards.

As with all CarboMer excipients and biomaterials, Poly(caprolactone) triol is fully supported by technical consultation, formulation guidance, and regulatory assistance to streamline pharmaceutical development programs and regulatory submissions.
