    Take home:

    Because several types of quasi-drugs converted into functional cosmetics in first half year of 2017, ingredients standard for cosmetics have to revise for the integration. MFDS has revised “Cosmetic Safety Standard” which includes ingredients requirements more than twice recently. Chemlinked help sorted out all these changes in this article.

    Dear Jo, many thanks for posting this. very helpful. but I have a few questions here: 1) Are you going to update Korea cosmetics chem-list? 2) For Changes to Restricted Ingredients List (Add conditions for ingredients used in hair dye products), actually they were prohibited in korea cosmetics but now the new entries to restricted list. Is it correct? 3) For Other amendments of restricted ingredients, the original restriction of those ingredients are not included in your list above. Is it right to say that the original restriction are not revised, and the new amendment has incorporated additional restriction? 4) what is the restriction of CHITOSAN GLYCOLATE? it appears in Other amendments of restricted ingredients, besides of thioglycolic acid. 5) Zinc Pyrithione has new restriction for hair loss... it refers to anti hair loss product or hair remover? 6) You mentioned a few restricted ingredients with their upper limits % allowed in oxidized hair dyes, are those limits% referring to the product (before mixing with peroxide and applying on hair) or the percentage ready-for-use (after mixing)? 7) Some restricted ingredients are allowed to use in hair dyes without specifying the oxidized dyes or non-oxidized dyes. could you clarify whether it is allowed to use in both types? Look forward to your clarification, Thanks Regards Roy Lu
    Thanks for your comments Roy, your questions help improve us as well. Let me explain to you one by one:1) we will update the list in some time, but the original lists are in Korean, plus the whole version is really long, so it will cost us a period to prepare; 2) correct; 3)for amendments list, we only point out the revised part, other restrictions that not mentioned remain still; 4)Sorry indeed for the typo, there is no CHITOSAN GLYCOLATE in the original list, we mistype this and now we delete it; 5) here refers to anti hair loss product, we will clarify it clearer. I hope these answers will be helpful, cheers.
    Thanks Jo, Your comments to #1-#5 are clear!! How about #6 and #7? 6) You mentioned a few restricted ingredients with their upper limits % allowed in oxidized hair dyes, are those limits% referring to the product (before mixing with peroxide and applying on hair) or the percentage ready-for-use (after mixing)? 7) Some restricted ingredients are allowed to use in hair dyes without specifying the oxidized dyes or non-oxidized dyes. could you clarify whether it is allowed to use in both types?
    6) the upper limits refers to concentration after mixing; 7) some ingredients (not mentioning used as oxidized dyes or non-oxidized substances) are compound allowed to use in either hair dye products. Cheers.
