Q
China | How should the notifier of a new cosmetic ingredient conduct an analysis of its safe use?
A

The notifier of a new cosmetic ingredient should conduct a comprehensive investigation and clearly describe the channels and methods for collecting adverse event reports. They should also indicate whether any adverse reactions or other reports of potential harm to human health have been associated with cosmetics containing the ingredient since their launch, and perform a necessary analysis of such information. Based on this, and in conjunction with the overall market use of the ingredient, the notifier should conduct a scientific and rational assessment of the ingredient’s history of use. This assessment should lead to a clear conclusion as to whether the ingredient has caused any serious adverse reactions or widespread adverse events, and whether it may pose a risk to human health.

For new ingredients with skin-whitening or spot-removal functions, particular attention should be paid to the safety risks of long-term application to human skin. For example, information should be provided on no fewer than 100 consumers who have continuously used the same product for a long period (one year or more). If such information cannot be provided, long-term human safety trials may be conducted as an alternative, and relevant research data should be submitted.
