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:

1(1) The use of the substance 1,2-cyclohexanedicarboxylic acid, 1-(phenylmethyl) ester, ester with 2,2,4-trimethyl-1,3-pentanediol mono(2-methylpropanoate) in the manufacture of any of the following products, if the substance is present in the product in a concentration greater than or equal to 0.1% by weight:
