what is Perchloroethylene (PCE) CAS 127-18-4?
CAS 127-18-4 PCE Perchloroethylene (also known as tetrachloroethene) is a chlorocarbon with the molecular formula of C2Cl4. It is a colourless liquid with a sweet odour that is most commonly used as a dry cleaning product of fabrics. Perchloroethylene is a non-flammable liquid, having no measurable flashpoint or flammable limits in air. It is miscible with most organic solvents but only slightly miscible in water.

What is PCE Used for?
PCE perchloroethylene is used primarily for metal degreasing and for dry cleaning, scouring, and sizing fabrics. PCE (CAS 127-18-4) is also used to make other chemicals (specifically Chlorofluorocarbons) and as an insulating fluid in electrical transformers.
Furthermore, PCE is also an ingredient in several products including:
- Aerosols
- Solvent Soaps
- Printing Inks
- Adhesives
- Glues
- Sealants
- Paint Removers
- Paper Coatings
- Rubber Coatings
- Water Repellent
- Leather Treatments
Is PCE perchloroethylene safe?
The chemical is toxic to humans at very low concentrations. People may be exposed to PCE by inhaling it, absorbing it through the skin, or ingesting it. It can cause dizziness, headaches, liver and kidney damage in people who've had chronic exposure.
Safety Precautions of PCE
- Keep containers tightly closed and store in a well-ventilated area.
- Keep away from food, beverages, and animal feed.
- Keep away from fire and do not smoke.
- In case of eye contact, immediately flush with plenty of water and seek medical advice.
- Wear appropriate protective clothing, gloves, and eye/face protection.
