Gamma-Butyrolactone (GBL): Uses, Health Risks & Global Regulations

Gamma-Butyrolactone (GBL) is a colorless, hygroscopic liquid with a wide range of legitimate industrial uses—from solvents and cleaning agents to chemical intermediates in pharmaceuticals and polymers. However, GBL has a darker side: when ingested, the body converts it into gamma-hydroxybutyrate (GHB), a controlled substance with sedative and euphoric effects. This dual-use nature makes GBL a valuable industrial chemical but also a public health and regulatory challenge. Industrial & Commercial Uses of GBL 1. Solvent Applications Paint removers & cleaners: GBL is a powerful solvent for polymers, resins, and coatings. Electronics & battery industry: Used in lithium-ion battery electrolytes and as a cleaning agent for precision parts. 2. Chemical Intermediate BDO precursor: GBL is closely tied to the C4 chemical chain, where it is converted into 1,4-Butanediol (BDO). Pharmaceuticals & agrochemicals: Functions as an intermediate in drug synthesis and crop protection products. 3. Specialty Applications Found in ink removers, adhesives, and superglue removers, where strong solvency is required. If your business sells GBL for industrial cleaning or specialty chemical use, optimize for long-tail keywords such as “GBL solvent for electronics” or “GBL in battery applications.”
