To ensure the safety of ingredients used in cosmetics, raw materials undergo chemical analysis. Despite safety measures taken by producers, impurities may still occur in the raw materials.
Using chemical analysis, occurence and levels of impurities are measured in the raw materials. An example of such a test is Mass Spectrometry. We check whether levels of impurities comply with regulatory standards, and assess the safety by using the information in our database. Aside from assessing all impurities, we take special care when we find impurities which contain heavy metals, or are carcinogenic, mutagenic or toxic to reproduction (CMR substances).
