A. Schuttelaar Cecilia Svedman Matthias Vey Marléne Isaksson Bo Niklasson Thomas Rustemeyer Magnus Bruze Contact Dermatitis AbstractBackgroundQuantitative risk assessment (QRA) for skin sensitization is used to derive safe use levels of sensitising fragrance ingredients in products. Post‐marketing surveillance of the prevalence of contact allergy to these ingredients provides relevant data to help evaluate the performance of these measures.ObjectivesTo determine a suitable patch test concentration for five fragrance materials that had hitherto not been tested on a regular basis. These concentrations are then to be used in a surveillance study with patch testing consecutive patients over an extended monitoring period.Materials and MethodsFuraneol, CAS.3658‐77‐3; trans‐2‐hexenal, CAS.6728‐26‐3; 4,8‐dimethyl‐4,9‐decadienal, CAS.71077‐31‐1; longifolene, CAS.475‐20‐7; benzaldehyde, CAS.10052‐7, were patch tested with other fragrance allergens in four clinics. Patch testing was conducted in three rounds, starting with the lowest concentrations of the five ingredients. The doses were increased in the subsequent rounds if no late‐appearing positive reactions and virtually no irritant reactions were reported.ResultsOverall, 373 patients were tested. No positive allergic reaction was reported to the five ingredients. Patch test results of other fragrance allergens are reported.ConclusionsThe highest test concentrations are each considered safe for patch testing consecutive patients. Further surveillance based on these preparations will evaluate the hypothesis that QRA‐driven consumer product levels of these fragrances can prevent sensitization. 10.1111/cod.14525 http://creativecommons.org/licenses/by-nc/4.0/ |
