In this online survey, information is collected to determine the level of suffering of fragrance-sensitive people. This is not a representative study, but rather a data collection from   fragrance-sensitive people aged at least 18. Participation in the online survey is voluntary. The survey is anonymous and does not allow any conclusions to be drawn about individual persons. Survey results are used for scientific publications, lectures or other communication channels. The conduct of the study was approved by the data protection officer of Ulm University of Applied Sciences and the ethics committee of Ulm University of Applied Sciences. Ulm University of Applied Sciences (THU) uses the online portal LimeSurvey for the online survey as part of order processing in accordance with Art. 28 of the General Data Protection Regulation. THU is responsible for the lawfulness of the data processing described above. The session cookies used by LimeSurvey as standard are necessary for the secure operation of the website and the implementation of the survey and therefore do not require the user's consent. No data is collected that could be used to identify you.

This study is conducted by Professor Dr Ursula Klaschka (Duftstoffe@thu.de) at University of Applied Sciences, Ulm, Germany (THU), represented by Prof. Dr Volker Reuter.  Mrs Heidi Wagner from the MCS support-group in Rosenheim (www.mcs-rosenheim.de) is involved to the creation and subsequent evaluation of the questionnaire from the perspective of those affected.

In the interests of better readability, we have refrained from using double designations and gendered terms. The abbreviated form of language does not imply any judgment.
