🔬 The Science

The European Union requires disclosure of 26 specific fragrances considered potentially allergenic in cosmetic products—a rule often called the ’26 allergens rule’ (Int J Hyg Environ Health, 2012). These fragrances must be listed on product labels if they exceed 0.001% concentration in leave-on products (those you don’t rinse off) or 0.01% in rinse-off products. The reasoning is straightforward: #1: these ingredients can cause skin sensitization in some people, and consumers deserve to know they’re present. This matters especially for deodorants because #2: many people experience allergic or irritant contact dermatitis—a type of skin inflammation or allergic reaction—on their underarms from cosmetic use (Int J Hyg Environ Health, 2012).

A study analyzing 374 deodorant products sold in Germany across three years (2008–2011) found that #3: up to 83% contained at least one of the 26 allergenic fragrances, while #4: up to 30% contained strong allergens in amounts exceeding the legal labeling threshold (Int J Hyg Environ Health, 2012). Interestingly, when allergenic fragrances were present, #5: most were classified as medium or weak allergens rather than strong ones (Int J Hyg Environ Health, 2012). The research suggests that mandatory labeling alone may not adequately protect consumers, since #6: many products still contain these ingredients legally but without clear, easy-to-understand warnings (Int J Hyg Environ Health, 2012).
