Argan powder, used in the cosmetic industry for the production of foundation, may be linked to occupational asthma.
A small study, presented at the European Respiratory Society (ERS) Annual Congress in Barcelona today (9 September 2013), has found the first evidence of a risk associated with the use of argan powder during the industrial production of cosmetics.
A sample of nine patients from a cosmetic factory in France were analysed in the study. All participants were exposed to the product in three different forms: crude granules, powder or liquid.
Out of the nine workers, four displayed asthma or rhinitis symptoms and had a blocked nose when handling argan powder. The results found that three of them had occupational asthma caused by argan powder, proved by specific challenge tests. Two of the four also had a positive allergy skin prick-test to argan powder.
Dr Emmanuelle Penven, lead author of the study, said: "Occupational asthma can be a debilitating condition if it prevents a person from working. This study is very preliminary but does suggest an association between argan powder and occupational asthma. Our initial findings warrant further research to understand any health risks associated with the compound."
