Abstract:
Aromas can give smell and/or flavor to a variety of products in the cosmetic and food industry. They are also used as e-cigarette additives. Some of those substances are recognized as fragrance allergens and can cause allergic reactions so there is a need to control their use. Gas chromatography is the method of choice for analyzing fragrance allergens because of their low boiling points. This study aimed to develop and validate a robust and simple method for the analysis of fragrance allergens in aromas for e-cigarettes. A method using gas chromatography coupled with a flame ionization detector was developed for 25 fragrance allergens. Optimized parameters were sample diluent, internal standard, and carrier gas. The output method was the one previously developed and optimized. The linearity of the method was >0.994 over the range of 0.5-40 μg/mL. Accuracy and precision were within the acceptance range. Limits of detection and quantification were determined, and calibration curves were plotted. The method was applied to three real samples of aromas. Thirteen fragrance allergens were detected. Concentrations varied in the range of dozens to thousands of μg/mL showed that concentrations of fragrances in aromas for e-cigarettes can be high and varies among products.
