Quantitative risk assessments of skin sensitization for 26 allergens in different consumer products in the Saudi market.

Fragrance chemicals are ubiquitous in cosmetics; however, they have been linked to allergic contact dermatitis. Allergy prevention involves two main strategies. Firstly, consumers are protected by limiting the maximum concentration of fragrance in a given product to avoid inducing allergies. Secondly, consumers who are already sensitized are protected by having the presence of such fragrance communicated to them. In this study, a validated GC-MS method was employed to quantify 26 allergens in 108 products marketed in Saudi Arabia.Additionally, a quantitative risk assessment (QRA) was performed on the studied cosmetics to determine the risk of inducing allergies. The results indicated that most allergens were present at acceptable concentrations, while 19 products carried a risk of inducing allergies. Furthermore, Lilial and Lyral, two prohibited fragrances, were detected in 97 products. It should be emphasized that this is the first study conducted in Saudi Arabia to evaluate the safety of the well-known 26 fragrance allergens. Hence, this study can potentially serve as a regional standard for future research.
