Chlorinated Paraffins are straight-chain hydrocarbons that have been chlorinated. They are being widely used in industry throughout the world since their introduction nearly 40 years ago. They are needed where chemical stability is highly desire in metalworking fluid formulations.

Chlorinated paraffins have been the subject of numerous health and environmental reviews. Regulatory attention was first focused on chlorinated paraffins in the United States in the mid-1970s when the US Environmental Protection Agency (EPA) undertook a comprehensive environmental and health review. Starting in the 1990's, Environment Canada began a similar review.
