4 phenolic substances need attention! Draft evaluation of replacement phenols in Canada
On January 13, 2024, Canada conducted a risk assessment of 15 alternative phenolic substances based on the Canadian Environmental Protection Act (CEPA) and issued a draft risk management assessment. The main purpose of this draft is to assess whether these substances pose a risk to the environment or human health. The public opinion period for the draft is until March 13, 2024.
The evaluation of 15 replacement phenols is announced as follows:
Evaluation Summary
According to the Canadian government's announcement, four out of these 15 replacement phenols (specific CAS numbers 118-82-1, 128-37-0, 36443-68-2, and 61788-44-1) are considered to have potential harmful effects on the environment. The remaining 11 substances are considered not to cause environmental damage at the current assessed exposure level.
Specific hazards of substances
Specifically, for the two chemical substances with CAS numbers 128-37-0 and 36443-68-2, although they do not fully meet the bioaccumulation requirements in CEPA, the Canadian government is considering implementing regulatory or non regulatory measures to limit their emissions due to their toxic and persistent characteristics. This is aimed at limiting its emissions and other related requirements. The Canadian Department of Environment has recommended adding these two to Part 2 of CEPA Schedule 1 to prevent environmental pollution and, if necessary, to prohibit related production activities.
The other two substances (CAS numbers 118-82-1 and 61788-44-1) have been identified as toxic and meet the standards for persistence and bioaccumulation in CEPA. Therefore, the Ministry of Environment is considering implementing more mandatory control measures. These measures may include gradually phasing out the production, use, sale, supply, or import of these substances, while also requiring control of their emissions to the minimum level of reliable testing. According to the instructions of the Ministry of Environment, these two substances will be added to Part 1 of CEPA Annex 1 in order to propose management measures for ecological and human health risks related to these substances.
Draft Summary
Phenolic substances are mainly used in industrial formulations as antioxidants and processing aids, helping to extend the service life of various industrial and consumer products. In Canada, these substances are widely used in lubricants, fuel additives, plastic products, as well as paints and coatings. In addition, they have limited applications in fields such as personal care products, food packaging, adhesives, sealants, and textile manufacturing.
These substances do not meet the standards of the Canadian Environmental Protection Act as they may have harmful effects on the environment. The draft is currently in a 60 day public consultation period, with a deadline of March 13, 2024.
