Introduction
PEG-75 is a polyethylene glycol polymer with an average molecular weight of 75 kDa. Its high molecular weight confers properties like viscosity enhancement and controlled release, making it suitable for use as a solubilizer, stabilizer, and binder in pharmaceutical manufacturing. The compound's biocompatibility and non-toxicity underpin its regulatory acceptance globally, primarily governed by agencies like the FDA and EMA.
Market Drivers for PEG-75
1. Rising Demand for Biologics and Parenteral Drugs
The global shift towards biologic therapies necessitates excipients that support stability and solubility of complex molecules. PEG-75's high molecular weight renders it ideal for:
- Lyophilization processes
- Enhancing protein stability
- Serving as a viscous carrier in injectable formulations
Statistics: The global biologics market expanded from $277 billion in 2020 to $460 billion in 2026, with anticipated compounded growth fueling excipient requirements [1].
2. Regulatory Favorability and Safety Profile
PEGs with higher molecular weights, like PEG-75, are recognized for their low toxicity and minimal immunogenicity. Regulatory agencies are increasingly endorsing PEG-based excipients, especially in parenteral formulations, which require stringent safety evaluations [2].
3. Expansion in Drug Solubilization and Delivery Technologies
Advancements in nanotechnology and delivery systems leverage PEG-75 to enhance solubilization of hydrophobic drugs. Its viscosity-modifying capabilities further optimize controlled-release formulations.
4. Growth in Cosmetic and Topical Applications
Apart from pharmaceuticals, PEG-75 finds use in cosmetic formulations as a thickening agent and moisturizer, expanding its market beyond pharmaceuticals.
