On February 7, 2025, Japan's Ministry of Health, Labour and Welfare, Ministry of Economy, Trade and Industry, and Ministry of the Environment jointly announced that, in accordance with the Basic Policy on Risk Assessment of Priority Assessment Chemicals under the Chemical Substances Control Law, they had conducted detailed monitoring of priority assessment chemicals manufactured or imported in quantities below 10 tons annually or with anticipated emissions under 1 ton.
The priority assessment chemicals subject to quantity monitoring include:
- Disodium 4,4'-bis[(4-anilino-6-morpholino-1,3,5-triazin-2-yl)amino]stilbene-2,2'-disulphonate
- Benzyl(dimethyl)(octyl)ammonium salt
- [Dimethyl(octadecyl)azaniumyl]acetate
- Ethyl 2-phenylpropionate
- A mixture primarily consisting of 2-{dimethyl[3-(3,3,4,4,5,5,6,6,7,7,8,8,8-tridecafluorooctanesulfonylamino)propyl]ammonium} acetate (over 95%) with N,N-dimethyl-3-(3,3,4,4,5,5,6,6,7,7,8,8,8-tridecafluorooctanesulfonylamino)propylamine
- Carbamic acid,1H-benzimidazol-2-yl-,methyl ester
The substances that have been delisted include:
- 4,4'-Diamino-3,3'-dichlorodiphenylmethane
- A mixture of bicyclo[2.2.1]heptane-2,5(2,6)-diaminedinitrile
Japan aims to further reduce the potential risks of chemicals to the environment and public health through these measures.
