Do you have any products containing “imidazolium” ionic solvents at home or work?

This is an opportunity to help research in Primary Biliary Cholangitis.

Primary biliary cholangitis (PBC) is an autoimmune disease of the liver. It leads to progressive damage to the intrahepatic bile ducts, cholestasis and eventual liver fibrosis. An autoimmune component is well described. However, since the disease is common in specific geographic areas, including the north of England, this suggests an environmental component. 

Research over the last 15 years has suggested that PBC might be triggered by exposure to certain chemicals (e.g. chemicals present in hair dyes, nail varnish etc.)

The liver theme in the National Institute for Health Research-funded Health Protection Research Uni ( is focused on examining and potentially identifying these chemicals. Since the project began, the work has included taking soil samples in the region. A chemical has been identified but the researchers do not know how it got into the soils.

The chemical found is one of many hundreds of similar solvent molecules, some of which are manufactured in the EU in large quantities. 


The purpose of this opportunity is to find out whether there are any products in the home or work containing the type of chemical the HPRU researchers found in the environment.

What will I be asked to do?

The researchers are looking for products with IMIDAZOLIUM chemicals listed on ingredients lists of any product at home or work.

If you find any, please take a photograph of the label and email it to Your email address will be kept strictly confidential.

Alternatively photographs can be sent direct to LIVErNORTH either by text to 07555951105 (this number is for text messages only) or be email:

If in doubt - please take a photograph and sent it anyway.

Results will be posted on the HPRU website and in LIVErNEWS, when they have been analysed.
