Yes, Trichloroethylene (TCE) CAS 79-01-6 is heavier than water. With a density of approximately1.46 g/mL at 20°C, compared to water's 1 g/mL, it is classified as a DenseNonaqueous Phase Liquid (DNAPL). This high density, combined with strong solvency, makes TCE highly effective for industrial cleaning, metal degreasing, and chemical applications.
Why Trichloroethylene TCE Is Heavier Than Water?
- TCE contains three chlorine atoms, which significantly increase its molecular weight.
- Its density of 1.46 g/mL means it sinks in water and does not mix easily, making it ideal for targeted cleaning.
- The high density also helps vapor degreasing systems condense solvent on surfaces for thorough cleaning.
What Is Trichloroethylene (CAS 79-01-6)?
High Quality 99.9% Trichloroethylene, commonly referred to as TCE, is a nonflammable, colorless liquid that is primarily used to degrease metal parts. This synthetic solvent is found in certain consumer products including adhesives, wood finishes, paint remover and stain remover.
Common Synonyms:
- Ethylene trichloride
- Trichloroethene
- 1,1,2-Trichloroethylene
- Triclene

What is industrial Trichloroethylene used for?
1. Industrial Cleaning & Metal Degreasing
Trichloroethylene solvent is widely used to clean and degrease metal parts like zinc, aluminum, brass, bronze and steel during manufacturing and assembly.
2. Textile Extraction & Processing
It dissolves grease, oil, fat, wax and tar easily. In textile industry, it cleans and treats cotton, wool and other fabrics.
3. General Industrial Solvent
Solvent TCE works for extraction, waterless drying and surface finishing. It is also added into adhesives, lubricants, paints, varnishes, paint removers, pesticides and cold metal cleaners.
4. Daily & Automotive Care Products
Trichloroethylene CAS 79-01-6 can be used in furniture care items, craft spray coatings, automotive maintenance products such as brake cleaners, and other common cleaning goods.
Is Trichloroethylene (CAS no: 79-01-6) Safe?
EPA has identified Trichloroethylene as "carcinogenic to humans" and has established regulatory limits for TCE in air and water.
The recommended threshold limit value for industrial exposure to TCE is 50 parts per million (ppm),8 and the Federal OSHA standard for TCE exposure in occupational settings is 100 ppm. Some states have stricter limits, such as California, where the exposure limit is set at 25 ppm.
