These three Irganox compounds are all primary phenolic antioxidants, but they differ in their molecular structure and performance: - **1010**: a tetrafunctional molecule offering high resistance to extraction. - **1076**: a monofunctional molecule, valued for its low volatility and excellent long-term thermal stability. - **3114**: a trifunctional molecule that often provides better thermal protection compared to monofunctional compounds. The choice depends on the polymer and the processing method. Does the analysis allow us to determine if the antioxidant has degraded? Yes. Sensitive techniques such as LC-MS/MS or HPLC allow us to quantify the amount of remaining additive, as well as the presence of its degradation products (oxidized metabolites). A high proportion of degradation products indicates a significant depletion of antioxidant capacity. Are there specific regulatory limits for Irganox in cosmetics? In the absence of a direct active ingredient status, these compounds are primarily controlled as impurities or substances originating from packaging. There is no listed limit as there is for a preservative. The laboratory will ensure that the detected concentration is below the toxicological threshold deemed acceptable within the framework of the product safety assessment (P&I). Are they considered active ingredients or contaminants? In the final cosmetic product, they are generally considered impurities or contaminants (leachable substances). They are not added for cosmetic purposes (hydration, UV protection, etc.), but their presence must be assessed for toxicological risk as part of the Product Information File (PIF).
