Challenge
Test
Putting cosmetic innovations through their paces – with our challenge test service for your formulations.
Quality assurance for your cosmetic products
A modern formulation must not only fulfil the growing expectations of consumers but above all guarantee the requirements for microbial stability.
Stability can be jeopardised by microbiological contamination that can occur during the manufacture of the product and, in particular, by the consumer himself. In order to ensure reliable preservation of your formulation in the event of possible microbial contamination,challeng tests are not only extremely important for the authorisation of cosmetic products, they are also required.
According to the European Cosmetics Regulation, the performance of challenge tests is mandatory as part of the safety assessment.
RELIABLE. SIMPLE. TRANSPARENT.

Challenge Test at Cosphatec: ISO 11930 and Ph. Eu. 5.1.3
We offer you precise challenge tests based on the established ISO 11930 and Ph. Eu. 5.1.3. methods. The two methods differ in terms of Test times and the Acceptance criteria for the valuation levels.
The selection of the test method and the customisation of the preservation system are carried out individually according to your needs and preferences.
challenge tests according to ISO 11930
ISO 11930 is an internationally recognised standard that defines the challenge test for cosmetic products. Our CFT according to ISO 11930 is widely recognised and offers you comprehensive control of the microbiological stability of your cosmetic products. The standard covers comprehensive test parameters, including bacteria, yeasts and moulds. The test evaluates bacteria from day 7, yeasts from day 7 with a slightly lower inoculation and moulds from day 14. Thanks to our transparent communication, you are always in control of the process.
pH. EU. 5.1.3: pH testing of cosmetic products
The pH.EU.5.1.3. standard is a proven pharmaceutical method for testing the microbiological stability of non-sterile pharmaceutical products. It can also be successfully applied to cosmetic products. The test evaluates bacteria at four test times and yeasts and moulds only after two weeks. The inoculation quantities vary between the test organisms and the two methods. The pH. EU. 5.1.3. sets stricter acceptance criteria for bacteria on day 2 and requires a higher log level reduction for yeasts and moulds.
Here you will find further information on the test methods.
