The significant new activity (SNAc) provisions of CEPA apply to this substance. It is suspected that new activities involving this substance could result in the substance becoming toxic under CEPA.

The SNAc provisions of CEPA trigger an obligation for a person to provide the Government of Canada with information about a substance when proposing to use, import or manufacture the substance for a significant new activity. The government then assesses the substance for potential risks to the environment and/or human health. If risks are identified, the government may impose risk management measures.

The significant new activities with respect to this substance are defined in the order as follow:

3(1) Subsection 81(3) of the Act applies with respect to a substance set out in the table to this subsection in respect of

(a) the use of the substance in the manufacture of any of the following products, if the product contains the substance at a concentration equal to or greater than 1.0% by weight:

(i) a consumer product to which the Canada Consumer Product Safety Act applies,

(ii) a cosmetic as defined in section 2 of the Food and Drugs Act;

(b) the importation of the substance in any of the following products that contain the substance at a concentration equal to or greater than 1.0% by weight, if the total quantity imported in all such products in a calendar year is greater than 10 kg:

(i) a consumer product to which the Canada Consumer Product Safety Act applies,

(ii) a cosmetic as defined in section 2 of the Food and Drugs Act; and

(c) any other activity involving the substance, if the total quantity of the substance involved across all activities, other than those referred to in paragraphs (a) and (b), in a calendar year is greater than 1 000 kg.

(2) Despite subsection (1), an activity is not a significant new activity if

(a) the substance is a research and development substance or site-limited intermediate substance as those terms are defined in subsection 1(1) of the New Substances Notification Regulations (Chemicals and Polymers); or

(b) the substance, or the product that contains the substance, is intended only for export.



To access the full description of the significant new activity requirements for this substance, including the information required to be submitted to the government, refer to the Canada Gazette publication or the Canada's Open Government Portal.

This substance was added to the DSL as an “Existing Substance” given that it was in commerce in Canada between 1984 and 1986 or it was in a product regulated under the Food and Drugs Act that was in commerce in Canada between 1987 and 2001.

The significant new activity (SNAc) provisions of CEPA apply to this substance. It is suspected that new activities involving this substance could result in the substance becoming toxic under CEPA.

The SNAc provisions of CEPA trigger an obligation for a person to provide the Government of Canada with information about a substance when proposing to use, import or manufacture the substance for a significant new activity. The government then assesses the substance for potential risks to the environment and/or human health. If risks are identified, the government may impose risk management measures.

The significant new activities with respect to this substance are defined in the order as follow:

2(1) Subsection 81(3) of the Act applies with respect to a substance set out in the table to this subsection in respect of

(ii) a cosmetic as defined in section 2 of the Food and Drugs Act; and

(c) any other activity involving the substance, if the total quantity of the substance involved across all activities, other than those referred to in paragraphs (a) and (b), in a calendar year is greater than 1 000 kg.
