| Resumo: | The European regulation on cosmetic products identifies 26 fragrance-related substances classified as likely to cause allergenic reactions. The regulation makes mandatory to declare the presence of these 26 substances on the cosmetic label when present at concentrations exceeding those stipulated. Of these 26 substances, known as potentially allergenic substances, 24 are well-defined volatile compounds whereas the other two are natural extracts. The present manuscript deals with analytical methods present in the literature that are applied for the quantification of those 24 potentially allergenic substances in cosmetics.; Kosmetikoei buruzko Europako araudian, erreakzio alergikoak eragin ditzaketen 26 substantzia identifikatzen dira. Araudiaren arabera, derrigorrezkoa da 26 substantzia horien presentzia kosmetikoaren etiketan agertzea, araudiak ezarritako kontzentrazioak gainditzen badira. 26 substantziatatik, 24 ondo definitutako konposatu lurrunkorrak dira, eta beste biak estraktu naturalak dira. Artikulu honetan, 24 substantzia alergeniko horiek kosmetikoetan kuantifikatzeko garatu diren metodo analitikoak aztertzen eta laburtzen dira.
