What is the future outlook for chlorinated paraffins?
The EPA’s decision to regulate mid and long chain chlorinated paraffins was based on their determination that lower chain length compounds are persistent and bioaccumulative in the environment. That determination was made using the risk assessment process that relied upon modeling and assumptions. After input from the manufacturers and end users, the EPA was able to refine the risk assessment and allow the continued production and use while requiring the generation of additional data. The EPA has not necessarily changed their opinion about the possible negative environmental impact of those chemicals however they have delayed their decision pending the conclusion of these new studies.
Why did the EPA approve mid and long chain chlorinated paraffins under Section 5 of TSCA for new chemicals and not Section 6 for existing chemicals?
By designating the chemicals under section 5 the EPA can require manufacturers to fund the environmental impact studies. Since the EPA does not know the outcome of the studies at this time they will need to evaluate the test results to determine their best course of action in the future. Once the studies are concluded the EPA may choose to regulate using Section 6.
Are all chain lengths of chlorinated paraffin subject to testing and future review by the EPA?
The short answer is yes. However, there are differences in the testing programs between the carbon chain lengths. The testing program for mid and long chain chlorinated paraffins has only recently been initiated. Very long chain chlorinated paraffins are currently undergoing long term environmental testing for bioaccululation, biodegradation and fate. Those tests are expected to run 12 – 15 years. Whereas, mid and long chain testing will be on a shorter time frame.
Why are the CAS numbers changing?
The EPA has determined that mid- and long-chain chlorinated paraffins are new chemicals. The CAS numbers that previously described those chemicals were not descriptive enough, were too broad in scope, and covered multiple chlorinated substrates. The new CAS numbers are much more definitive and are based on the raw material that is used to manufacture the product.
Is there a difference between a mid chain paraffin and a mid chain alpha olefin?
Paraffin based raw materials are derived from petroleum refining while alpha olefin based material are derived from natural gas. In terms of physical properties, the alpha olefin based products are typically less viscous and are lighter in color than paraffin based products.
How sustainable and environmentally responsible is the manufacturing process at Qualice?
Qualice is committed to environmental stewardship throughout the manufacturing process. The production process does not generate any hazardous waste. The chlorine Qualice uses is produced and consumed onsite. This means:
  • Qualice's primary raw material, chlorine, is back integrated to salt, water and electric energy which is environmentally responsible and economically sustainable.
  • No energy is used to liquefy chlorine which would be required to receive this raw material by rail
  • No energy is consumed for rail transportation
  • No hazardous exposure to the public during rail transportation. Chlorine is designated as a PIH (poison by inhalation) which also contributes to higher rail rates and insurance premiums
