RESUMO
Ingredient chemicals like fragrances may cause adverse health effects. Frequent health risk assessments and stringent management of consumer products are of paramount importance to reduce these serious occurrences. In this study, the respiratory and dermal health effects were assessed in relation to air fresheners. Twenty six fragrance ingredients, thirty four biocidal ingredients, and sixteen hazardous ingredients were analyzed and assessed according to their risk to human health on five groups by application type in eighty two air fresheners. For hazard characterization of ingredients, toxicological information on the intrinsic properties of the ingredients was collected, and reference values were determined as chronic NOAEL. Exposure assessment was performed in two steps. The 95th exposure factor values were used to estimate exposure to assume the worst-case scenario and the maximum concentration determined by the product purpose and application type was used type in tiered 1 assessment. The values input into the exposure algorithms were developed via the exposure route. In the tiered 2 assessment, the 75th exposure factor values were used to estimate the assumed reasonable exposure to ingredients. Six ingredients for the inhalation and twelve ingredients for the dermal route were conducted for tiered 2 assessment. This study showed that the assessed ingredients have no health risks at their maximum concentrations in air fresheners. The approach should be used to establish improved guidelines for specific ingredients that may pose inhalation and dermal hazard.
