Benzoic acid contained in tailor's chalk was identified as the cause of nasal hyperreactivity among the students of a fashion school. This result was obtained by interviewing the manufacturer of the chalk and the 87 students of the school subsequent to the complaints. In addition, provocation tests with healthy volunteers were conducted. Benzoic acid is added to chalk to facilitate its removal from clothes during ironing.
