Application:

Solvent:

Its high polarity makes it an effective solvent for many applications, including as a component in the electrolyte for lithium batteries (when mixed with a lower-viscosity solvent).

Cosmetics:

It can be found in some cosmetics and is considered to have low irritation and sensitization potential at typical use concentrations.

Industrial:

It is used in products like paint and adhesive removers and can act as a plasticizer.

Other:

It is also used in electrospray ionization mass spectrometry to improve analyte charging in low-surface-tension solutions.

Safety Profile:

Propylene Carbonate is generally considered to have low toxicity. May cause mild eye irritation. Use appropriate personal protective equipment including gloves and safety glasses when handling. The substance is biodegradable and has low environmental impact. For detailed safety information, consult the full Safety Data Sheet (SDS).

Storage Requirements:

Store in a cool, dry, well-ventilated area away from direct sunlight. Keep containers tightly closed and sealed. Maintain storage temperature between 5-35°C. Protect from moisture.

Transport & Packaging:

Propylene Carbonate is packaged in HDPE plastic drums (25 kg or 200 kg net weight per drum). Transport as non-hazardous material under normal conditions. Ensure containers are properly sealed and protected from physical damage during transportation. Store away from incompatible materials.
