If you introduce a cosmetic product on the European market for the first time, you must notify this product to the European Cosmetic Products Notification Portal (CPNP). This makes information about cosmetic products electronically accessible to authorities of the member states. With emphasis: a CPNP notification is not an “approval” of your product. CPNP also does not reject products. A product is signed up and ready. Nothing more, nothing less.
The idea behind CPNP is that at European level insight is gained about the products that are present on the European market. Authorities can find information about compounds if, for example, health problems occur.
