Background: The National Institute of Environmental Research (NIER)’s classification of and airborne fraction ratio for consumer chemical products (CCP) does not ref lect the characteristics of various product classifications.
Objectives: The purpose of this study was to reclassify the types of spray products according to the diverse spray characteristics of CCPs to evaluate the airborne fraction ratio of representative spray types and to compare them with previous CCPs types and airborne fraction ratios.
Methods: One thousand seven hundred two products were selected through market research, and 932 newly reported products were selected. After that, 200 were selected to evaluate products with potential inhalation exposure. After classifying six product types that are expected to show differences in the airborne fraction ratio according to the type of product, a final 38 products were selected for use in the airborne fraction ratio through random sampling.
Results: CCP has been reclassified from two to six types so that the characteristics of all products are well- ref lected. The NIER simply had two airborne fraction ratios, but the results of experiments with six types of products showed a significant difference in values (p<0.01). Airborne fraction ratios of propellant general foam, pump general aerosol, and pump trigger foam in spray type, which were not previously present in NIER, were 7.1%, 24.4%, and 3.5%, respectively.
Conclusions: For the diversified types of CCPs, the newly proposed classification was more appropriate than the existing
NIER classification. The airborne fraction ratio was also different for each type, so a new value was suggested.
