Testing

Laboratory testing

To prepare a safety assessment (CPSR) and product information file (PIF), two product tests are required. These are the challenge test and the stability test. The challenge test is performed to test the preservation of your product. The stability test is done with us in the final packaging, so that the compatibility between the product and the primary packaging is demonstrated. We are happy to provide both tests for you.

Stability test (including compatibility)

The stability test for a cosmetic product is performed to determine the shelf life of a product. With this, the responsible person of the product substantiates the declared shelf life on the packaging.

The stability test must be carried out in the final packaging in order to exclude any interaction between packaging and product.

Challenge test

The challenge test for a cosmetic product is performed to determine the shelf life after opening a product. The responsible person hereby substantiates that the product shows no risk of microbiological contamination. Supporting microbial stability is an obligation from the Cosmetic Regulation, EC 1223/2009. This makes the challenge test an obligation in the safety assessment (CPSR) and the Product Information File (PIF)
