Cosmetic stability testing at a UK lab
Do you sell cosmetics and require stability testing? We offer cosmetic stability testing at UK labs. Read on to learn more.
Cosmetic stability testing involves storing a cosmetic under controlled conditions and reporting changes in product characteristics at pre-determined timepoints. Results are presented in a stability test report and submitted as part of the cosmetic safety assessment process.
There are typically two main types of conditions under which stability testing takes place: room temperature and elevated temperature. Room temperature is, as it sounds, at around 20 degrees Celsius, where as elevated temperature – or ‘accelerated’ – testing takes place at 45 degrees Celsius.
The purpose of stability testing is to identify safety or quality issues that might arise over time. For example, after 6 months does the colour or odour change? Do the ingredients of the cosmetic interact with the container to produce harmful chemicals or an undesirable appearance? This information is reported in a cosmetic stability test report. Cosmetic stability testing is required under UK and EU cosmetic regulations.
Price depends on a number of factors: accreditation status of the lab, duration of the test, parameters of the test, number of timepoints. You can spend anything from £200 to £5000 for a stability test. But you should not need to spend more than £500 for a stability test especially if you choose a non-accredited testing lab.
The duration of the stability test depends on scope of test.
To undertake a cosmetic stability test you should provide 50 ml or 50g of sample in the marketed pack.
