BACKGROUND: Preservatives and fragrances are important and frequent skin sensitizers, found in a wide range of products intended for personal and occupational use. OBJECTIVES: To examine the use of preservatives and fragrances in certain cosmetics and detergents on the market. The product types studied were shampoos, hair conditioners, liquid soaps, wet tissues, washing-up liquids, and multi-purpose cleaners. MATERIALS/METHODS: Ingredient labels of 204 cosmetic products and ingredient data sheets of 97 detergents, available on company websites, were examined. RESULTS: The preservatives most frequently identified were phenoxyethanol, methylparaben, sodium benzoate, propylparaben, and methylchloroisothiazolinone/methylisothiazolinone. Parabens were found in 44% of cosmetics and 9% of detergents; formaldehyde-releasers in 25% of cosmetics and 8% of detergents; and isothiazolinones in 23% of cosmetics and 28% of detergents. The fragrances most frequently identified were linalool, limonene, hexyl cinnamal, butylphenyl methylpropional, and citronellol. Eighty-eight per cent of the products contained fragrances, and any of the 26 fragrances requiring labelling were found in half of the cosmetics and one-third of the detergents. CONCLUSIONS: Several preservatives and fragrances with well-known skin-sensitizing potential were common in the examined product types. Such products may be used several times a day by consumers and workers.
