Market Overview
What is PEG-400 and Why Is It Significant?
PEG-400 (Polyethylene glycol with an average molecular weight of 350–600) is a colorless, hygroscopic, viscous liquid. It acts as a solvent, plasticizer, and binder. Its pharmaceutical uses include:
- Use as a carrier or solubilizer for poorly water-soluble drugs
- Laxative formulations (e.g., Miralax)
- Component in topical and injectable formulations
- Vehicles in biotech applications, such as drug conjugation and controlled-release systems
Market Size (2023): USD 700 million
Based on global sales, manufacturing capacities, and application expansions.
Projected Growth (2023-2030): USD 1 billion; CAGR: 5-6%
Regulatory Landscape Impact
Regulatory agencies like the FDA (U.S.) and EMA (Europe) classify PEGs, including PEG-400, as Generally Recognized As Safe (GRAS). However, increasing scrutiny over PEG-related hypersensitivity risks and impurities influences manufacturing and quality standards. Expanded approvals in biologics and personalized medicine bolster PEG-400 demand, with evolving policies promoting innovation.
