The packaging of a cosmetic product must not release dangerous substances which could compromise the safety of consumers: the study of the case-by-case interaction is of utmost importance as is the highlighting of the elements relevant for an estimate of the toxicological risk:
Screening tests: a valid support particularly when the exact composition of packaging materials is unknown.
Mass Spectrometry: it characterizes all the substances which can potentially migrate in the cosmetic product, namely volatile, semi-volatile and non-volatile organic molecules that are identified in the applicability of the method and on the basis of known mass profiles conditions.
ICP-MS and X-ray Fluorescence Techniques: they highlight the presence of metals and are useful with colored packaging.
The goal is to identify the substances that the packaging may potentially transfer.
