Canada Approves Eight Hydrocarbon-Based Substances after Environmental Assessment

On April 20, 2024, the Canadian government announced the approval of eight hydrocarbon-based chemicals following a thorough assessment under the Canadian Environmental Protection Act, 1999 (CEPA). According to the findings, these substances are safe in terms of their effects on human health and the environment and do not meet the strict toxicity criteria of CEPA.

Substances Evaluated

The assessment, conducted by the Minister of Health and the Minister of the Environment, examined substances that are widely used in industries ranging from construction materials to household products. The substances include:

- Petroleum resins and hydrocarbon resin used primarily in adhesives.

- Polymerized C5-12 distillates, a petrochemical used in intermediate stages of manufacturing.

- Oxidized hydrocarbon waxes containing EA and 2-MAE, substances previously evaluated and found to be safe.

- Alkylated naphthalene sulfonate sodium salt polymers with formaldehyde, used in pest control products and industrial applications.

- Heavy oxo ends, used in applications such as industrial defoamers.

- Sulfurized petroleum, used in metalworking and other industrial applications.

Low Environmental and Health Risks

These assessments ensure that none of the substances pose significant risks to the environment or human health under current use and disposal practices. The investigation confirmed the low ecological and human health risks associated with these materials and supports their continued use in Canada under regulated conditions.

Government Commitment

This decision is consistent with ongoing efforts to ensure environmental safety and public health and reflects the government’s commitment to uphold the standards set by CEPA.
