Description

Glycine-Lactic Acid Copolymer is a synthetic, biodegradable polymer formed from the condensation of glycine and lactic acid monomers. This copolymer is valued for its biocompatibility and controlled degradation profile, making it a critical material for advanced biomedical and controlled-release applications. It is primarily utilized by manufacturers in the pharmaceutical, medical device, and specialty chemical sectors seeking innovative polymer solutions.

Application

• Biodegradable Medical Implants: Used as a resorbable material for sutures, bone fixation devices, and tissue engineering scaffolds.
• Controlled Drug Delivery Systems: Serves as a matrix for the sustained and targeted release of active pharmaceutical ingredients (APIs).
• Cosmetic & Personal Care Formulations: Functions as a film-forming agent, moisturizer, or carrier for active ingredients in advanced skincare products.
• Specialty Adhesives & Coatings: Employed in the development of bio-based, degradable adhesives and protective coatings.
• Agricultural Technology: Utilized in controlled-release systems for fertilizers, pesticides, and plant growth regulators.
• Research & Development: Acts as a key intermediate or model polymer for studying biodegradation kinetics and polymer-drug interactions.

Quality Control

Our Glycine-Lactic Acid Copolymer is produced under a strict quality management system. Each batch is tested to ensure compliance with critical parameters such as molecular weight distribution, inherent viscosity, residual monomer content, and biodegradation rate. Certificates of Analysis (COA) detailing these specifications are provided with every shipment to guarantee traceability and consistency for your R&D and production needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and should be kept under dry conditions to prevent hydrolysis and maintain polymer integrity.
