Answer: According to the "Regulations", new cosmetic ingredients with antiseptic, sunscreen, coloring, hair dyeing, freckle removal and whitening functions can only be used after registration with the drug regulatory department of the State Council; Other new cosmetic ingredients shall be filed with the drug regulatory department of the State Council before use. This is based on the principle of risk management, which implements registration management for several types of relatively high-risk ingredients, and implements record management for other ingredients. In the process of research and development of new cosmetic ingredients, it is often found that a new ingredient may have multiple functions at the same time. Before applying for registration or notification, the registrant or notification person of a new cosmetic ingredient shall conduct a comprehensive combing and full study of the actual functions that the new ingredient may have, and make a scientific and reasonable judgment on whether the new ingredient should be declared for registration.
