Perchloroethylene (PERC)


Perchloroethylene, commonly referred to as PERC or PCE is a clear and non-flammable liquid solvent that emits a pleasant, ether-like fragrance. It is a chlorinated hydrocarbon with the chemical formula C2Cl4 & Cas No: 127-18-4. Perchloroethylene has long been the dominant solvent used in global dry cleaning operations, particularly in the Dry Cleaning & Laundry Industry. Its main purpose is in the removal of persistent residues such as dirt, dust, greases, stains, mud, and oil from various materials during the dry cleaning process. Lets have a look at few of its Advantages, Disadvantages, Alternatives, Packing details & Handling in depth.

Advantages of PERC or PCE

  • Non-combustible
  • Eliminates stubborn and tough stains from organic residues
  • When used with caution, it avoids causing any damage or corrosion to the dry cleaning equipment
  • Capability to disassemble or dissolve accumulated dirt, effectively facilitating its removal
  • Its low viscosity allows for improved cleaning performance
  • Possesses the capability to undergo numerous cycles of recycling and reuse without any issues
  • It is a textile-friendly chemical that does not negatively affect dyes or react with the fabric of the garment.
  • Clear Colorless Appearance


Disadvantages of PERC or PCE

  • THREAT TO HUMAN AND ANIMAL HEALTH: This substance poses a carcinogenic risk to humans. Human studies suggest that being exposed to PERC may elevate the likelihood of developing various cancers, including but not limited to bladder cancer, liver cancer, lung cancer, multiple myeloma, and non-Hodgkin’s lymphoma. The International Agency for Research on Cancer (IARC) has categorized PERC as a Group 1 carcinogen for humans. Supporting evidence is provided by the Centers for Disease Control and Prevention here.
  • Neurological Impact: Prolonged exposure to PERC can lead to neurological effects, presenting as headaches, dizziness, and lack of coordination. In instances of heightened exposure, there is a potential for central nervous system depression to occur.
  • Stringent Regulations: Owing to the health and environmental hazards linked with PERC, regulatory bodies in various nations have enforced strict prohibitions on its utilization, management, and disposal. As a result, certain dry cleaning establishments utilizing this solvent have been compelled to cease their operations.
  • Groundwater Contamination and Hazard: Perchloroethylene has a persistent presence in the environment, posing a risk of contaminating groundwater. Inadequate disposal or unintended releases can result in enduring environmental harm.
  • Indoor Air Quality Concerns: The utilization of Perchloroethylene in Indoor processes can contribute to indoor air pollution. Residues may be emitted during the cleaning procedure, exposing both workers and customers to potential health risks.


Alternatives to Perchloroethylene

Addressing the aforementioned highlighted issues, there is an ongoing initiative to gradually eliminate or diminish the utilization of PERC across diverse industries. The emphasis is on embracing safer alternatives to safeguard both human health and the environment. If you are searching for a substitute for PERC that avoids health and environmental risks, consider choosing from the following alternatives:


Packaging & Storage Information of Perchloroethylene

  • 300 kilograms of brand new intact barrels
  • It should be stored in original tightly closed container, in dry conditions.
  • The selection of containers, such as storage barrels, can impact the accumulation and dissipation of static electricity. It is important to keep containers tightly closed and handle them with care. When opening containers, it is advisable to do so slowly to control any potential pressure release. Store the containers in a cool and well-ventilated area. Additionally, it is crucial to ensure that storage containers are properly grounded and bonded. This applies to fixed storage containers, transfer containers, and associated equipment to prevent the build-up of static charge.
