The Government of Canada has officially repealed the 2-Butoxyethanol Regulations (SOR/2006-347) and replaced them with new, updated rules under the Certain Products Containing Toxic Substances Regulations (SOR/2025-36). The move is part of a broader effort to simplify and streamline toxic substance regulations under the Canadian Environmental Protection Act (CEPA), 1999.
What Is 2-Butoxyethanol?
2-Butoxyethanol (2-BE), a chemical compound used in many cleaning and coating products, has potential health and environmental impacts. The original regulation limited 2-BE levels in certain indoor consumer products such as cleaners, paints, and strippers.
Key Changes in the New Regulation
Under SOR/2025-36, the previous rules are maintained with minor adjustments and now fall under a broader regulatory framework. The scope still applies only to ready-to-use indoor products, excluding those meant for export, industrial processing, scientific research, or laboratory use.
Updated Concentration Limits

Manufacturing and Import Restrictions
Manufacturing or importing products that exceed the above limits is prohibited, with exceptions if:
• The product is meant to be diluted, and post-dilution it complies with the limits.
• The manufacturer or importer holds a government permit.
• The product is only for export or is transiting through Canada.
Sales Rules
Selling non-compliant products is also banned, unless:
• They are made for dilution, and meet limits when diluted.
• They were manufactured or imported under a permit, and sold within one year of its expiry with proper instructions.
Compliance and Testing
2-BE content must be measured using standardized testing methods published by Environment Canada, applicable across relevant product categories.
Industry Obligations & Transition
Although the old regulation is repealed, the requirements remain active under the new regulation. Companies must now refer to the Certain Products Containing Toxic Substances Regulations for updated compliance details related to 2-BE and other regulated substances.
Why This Matters?
This update aligns with Canada’s push to make chemical safety rules more clear, efficient, and harmonized across product types. Businesses must stay informed to maintain compliance and avoid enforcement actions.
