Why Vertrel specialty fluids are a suitable replacement for N-propyl bromide and Trichloroethylene

Why are Vertrel fluids a suitable replacement for nPB?

Recently, the National Toxicity Program issued a report, dated August 2011, “Toxicology and Carcinogenesis Studies of 1-Bromopropane in F344/N Rats and B6C3F1 Mice (Inhalation studies).” https://ntp.niehs.nih.gov/ntp/htdocs/LT_rpts/TR564.pdf

The report concluded that there was “clear evidence of carcinogenic activity” in female mice and rats. As a result of this finding, Cal/OSHA has set an 8-hour worker permissible exposure limit (PEL) of 5 ppm. In addition, the American Conference of Governmental Industrial Hygienist (ACGIH) in 2011 has proposed a TLV of 0.1 ppm. Vertrel specialty fluids can replace nPB, providing the cleaning efficacy needed while addressing safety and health concerns. Here are five reasons it is an excellent replacement for nPB:

  1. Exposure Limit: Vertrel fluids have exposure limits around 200 ppm. By comparison, Isopropyl alcohol (rubbing alcohol) has an exposure limit of 200 ppm. The exposure limit of nPB exposure limit is measured between 5 ppm – 10 ppm by varying standards organizations.
  2.  Cleaning Performance: Vertrel specialty fluids have the broadest range of cleaning power of any solvent family. KB values (a measure of cleaning power) range from 11 to a high of 110. Vertrel can match nPB’s cleaning power.
  3. Solvent Maintenance: Vertrel fluids are inherently stable and do not need acid acceptance testing or stabilizer maintenance unlike nPB. In addition, the relatively high exposure limit of Vertrel enables the use of open top vapor degreasers, and solvent air monitoring can be kept to a minimum.
  4. Solvent Usage: Today’s cleaning equipment manufacturers have improved system design resulting in significant reductions in the amount of solvent emissions and reducing overall operating costs. Vertrel is cost competitive with nPB as a result of the emissions reduction.
  5. Global Acceptance: These specialty fluids are globally accepted as a safe cleaning material. Many countries have classified nPB as a reproductive toxin. In Europe, nPB is labeled as R60 (may impair fertility); R63 (possible risk of harm to the unborn child); and R48/20 (harmful: danger of serious damage to health by prolonged exposure through inhalation).


Vertrel specialty fluids have similar solvency strength as nPB. It is non-flammable, safe, and requires no stabilizers, making it an ideal replacement for nPB. Opteon™ products are also a great replacement for nPb.
