Background: Fragrance substances in consumer products can cause adverse health effects such as contact allergy. In South Korea, consumer chemical products must list 26 known fragrance allergens on product labels when they contain more than 0.01%. Fragrance substances are mostly used in combination, so co-exposure can occur via use of a consumer chemical product. Co-exposure to fragrance allergens may show a synergistic effect on the human body. Objectives: The aims of the study were to analyze the characteristics of fragrance allergens in consumer chemical products available on public websites and to identify the co-occurrence patterns of fragrance allergens. Methods: The chemicals in 1,443 ingredient disclosures for consumer chemical products were collected through the Ecolife database. The 26 labelled fragrance allergens were identified by category of consumer chemical product. The co-occurrence patterns of the 26 labelled fragrance allergens were analyzed by frequent pattern mining. The unlabelled fragrance allergens presented by European Union Scientific Committee on Consumer Safety were also identified. Results: Consumer chemical products contained an average of 5.3±4.2 substances among the 26 labelled fragrance allergens. More than 85% of air fresheners, deodorizing agents, and fabric softeners contained at least one of the 26 labelled fragrance allergens. The most frequently contained fragrance allergens were limonene (50.5%), linalool (49.9%), hexyl cinnamal (34.0%), and citronellol (28.3%). 16.7% of consumer chemical products showed a co-occurrence of limonene, linalool, hexyl cinnamal, and citronellol. Thirty-eight unlabelled fragrance allergens were found in the consumer chemical products, with hexamethylindanopyran (25.2%) being the most frequently contained substance. Conclusions: The characteristics and co-occurrence patterns of 26 labelled fragrance allergens would be useful information for the management of co-exposure to fragrance allergens in consumer chemical products. It is necessary for attention to be paid to unlabelled fragrance allergens.

The recent humidifier disinfectant disaster has caused a great change in our society and lead the Korean people to lose faith in the government and corporations. To overcome this mistrust, the government and corporations have undertaken certain efforts, including a voluntary agreement on consumer product safety. All the ingredients of a consumer product should be disclosed according to this voluntary agreement. There were also unexpected benefits occuring from this process. We found that the concept of corporate responsibility for product safety differed greatly among the various actors in Korean society. Corporations believed that a product could be considered safe if it contained no regulated substances. We have come to believe that this may be an important cause of the humidifier disinfectant disaster. The Korean government, corporations, and civil organizations have reached a consensus that it is a corporation's responsibility to evaluate the risks of products before they are introduced to the market. However, the limitations of these voluntary efforts are clear, and the legal system needs to be improved. We suggest that the concept of extreme recklessness should be introduced into regulations on product safety.
