According to the Gazette on April 3, 2023, Japan added six substances to the List of Priority Assessment Chemical Substances (PACs) following the removal of six substances on March 31. This brings the total number of PACs to 218.
The details of changes to the list are presented in the table below.
Substance name | |
Six substances added into list | Sodium salt of 2,2',2'',2'''-(ethane-1,2-diyldinitrilo)tetraacetic acid |
alpha,alpha'-[(Alkyl(C=8-18, normal chain)azanediyl)bis(ethane-2,1-diyl(or methylethane-2,1-diyl))]bis{omega-hydroxypoly[oxyethane-1,2-diyl/oxy(methylethane-1,2-diyl)]} (The repeating number of repeating unit is an integer 1 or more.) (It is limited that the number-average molecular weight of the polymer is less than 1,000.) | |
Salt of {ester of 2-hydroxy-N-(2-hydroxyethyl)-N,N-dimethylethan-1-aminium and [saturated fatty acid(C=10-18, normal chain)(or unsaturated fatty acid(C=18, normal chain))]} or salt of {ester of 2-hydroxy-N-(2-hydroxypropyl)-N,N-dimethylpropan-1-aminium and [saturated fatty acid(C=10-18, normal chain)(or unsaturated fatty acid(C=18, normal chain))]} | |
alpha-(Alkyl(C=6-18))-omega-hydroxypoly[oxyethane-1,2-diyl/oxy(methylethane-1,2-diyl)](It is limited that the number-average molecular weight of the polymer is less than 1,000.) | |
alpha-Hydro-omega-[(3-methylbut-3-en-1-yl)oxy]poly(oxyethane-1,2-diyl) (The repeating number of repeating unit is an integer 1 or more.) (It is limited that the number-average molecular weight of the polymer is less than 1,000.) | |
[alpha-(Alkanoyl(C=8-18, normal chain))-omega-methoxypoly(oxyethane-1,2-diyl) or alpha-(alkenoyl(C=8-18, normal chain))-omega-methoxypoly(oxyethane-1,2-diyl)] (The repeating number of repeating unit is an integer 1 or more.) (It is limited that the number-average molecular weight of the polymer is less than 1,000.) | |
Six substances removed from the list (now classified as general chemicals) | Methyl dodecanoate |
o-Dichlorobenzene | |
Ethylamine | |
Benzyl benzoate | |
Camphene | |
Chlorodifluoromethane |
Under the framework of Chemical Substance Control Law (CSCL), manufacturers and importers of PACs need to report to the Ministry of Economy, Trade and Industry (METI) during the period from April to June each year the production and/or import volume in the previous calendar year, the use category, and the production site, etc.
It should be noted that the six deleted substances and the six added substances can be reported as general chemicals this year.
