Updates to the Japanese Positive List Proposed


New draft Tables 1 and 2 of the Japanese Positive List have been posted on Japan’s Ministry of Health, Labour, and Welfare (MHLW) website. The updates are based on requests submitted by interested parties between April 26 and July 15 of 2022, to add new substances to Table 2 (List of Additives), and to confirm the inclusion of some substances that were on the “pending” list.
