ChemLinked Notes

South Korea adopts the negative list to regulate the ingredients used in cosmetics. This means if an ingredient is not listed in the prohibited ingredient list or is used under the limitation for the restricted ingredient list, then the ingredient can be used for manufacturing a cosmetic product.

The addition of CAS No. and chemical names are expected to help enterprises look up the ingredients more quickly and correctly.
