About low boiling point naphthas

Low boiling point naphthas (LBPNs) are a group of petroleum substances produced by distilling crude oil. In addition to uses within the petroleum sector, LBPN substances are used as solvents. They are present in a wide variety of products available to consumers, including:

Some LBPNs may also be used in the manufacture of food packaging materials and in other products used in food processing establishments, like lubricants and cleaners.

Safety of low boiling point naphthas

Under Canada’s Chemicals Management Plan, we review and manage the potential risks that chemical substances can pose to consumers and the environment. The first stage of the review process is a draft chemical risk assessment.

We have completed the draft assessment of a group of 27 LBPN substances. We are proposing that 17 of these substances may cause developmental and nervous system effects if they  are inhaled or come into contact with skin.

Some products available to consumers contain these LBPNs and may be harmful to human health. These include:

We are also proposing that LBPNs do not pose a risk to the environment.

What we’re doing

Our assessment is not yet final. We are continuing to evaluate the potential risk posed by LBPNs before we publish our final conclusion. This includes:

If the final assessment confirms our proposed findings, we will consider taking measures to reduce your exposure to LBPN substances from certain products available to consumers. This may include adding the LBPNs of concern to:
