Project: Consumers, cosmetics and skin sensitizers

Preservatives, hair dyes and fragrances are frequent causes of contact allergy. Information on allergens in consumer products is scarce, and ingredient labels on cosmetics are often difficult to read.

The aim is to create a scientific basis for preventive measures to reduce contact allergy and dermatitis affecting consumers, workers and dermatitis patients. Hair dye substances, preservatives, and fragrances in products used by consumers and workers are of special concern. The composition of large samples of products is studied according to ingredient labelling. Readability of ingredient labelling is investigated. The reactivity to a preservative is assessed by exposure mimicking normal use. The project will increase knowledge on exposure to important allergens and is expected contribute to improved risk assessment, prevention and diagnosis of contact allergy.

Collaboration is performed with Professor Jeanne Duus Johansen, National Allergy Research Centre and Copenhagen University Hospital Gentofte, Denmark, Professor Wolfgang Uter, Friedrich-Alexander-University Erlangen/Nürnberg, Germany, and Dr Ian R White, St Thomas’ Hospital London, UK.
