The responsible person in cosmetics refers to the natural or legal person who is established within the European Economic Area (EEA) and who is responsible for ensuring that a cosmetic product complies with all relevant EU legislation, including the Cosmetics Regulation (EC) No 1223/2009.

The responsible person is responsible for ensuring that a cosmetic product is safe for human health and the environment, and that it is properly labeled, packaged, and marketed. This includes ensuring that the product is adequately tested and that the necessary information, such as the product ingredients and safety information, is included on the product labeling and in the product documentation.

The responsible person must also maintain a Product Information File (PIF) for each cosmetic product, which contains information about the product, its safety assessment, and its labeling. This file must be made available to the relevant authorities upon request.

In short, the responsible person is responsible for the overall compliance of a cosmetic product with EU legislation and for ensuring that the product is safe for use. The responsible person must ensure that the product complies with all relevant legislation and that the necessary information is made available to consumers and regulatory authorities.
