Institute Warns: "Do Not Use for Wiping Mouth or Contact with Food"

The Seoul Institute of Health and Environment announced on December 8 the results of tests for the presence of formaldehyde, fluorescent whitening agents, and benzophenone in 21 types of disposable paper napkins and 84 types of decorative napkins with colorful prints and patterns, which are sold on online platforms, traditional markets, and small household goods stores.

All 21 disposable paper napkins classified as sanitary products were domestically produced, while all 84 decorative napkins classified as manufactured goods were imported.

Test results revealed that among the 84 decorative napkin samples, formaldehyde was detected in 8, fluorescent whitening agents in 14, and benzophenone in 23. In contrast, none of these harmful substances were detected in the disposable paper napkins.

Formaldehyde and fluorescent whitening agents can cause irritation to the respiratory system or skin upon contact. Benzophenone is a carcinogenic substance that can remain in printing ink.

The institute emphasized, "Decorative napkins should not be used for wiping the mouth or hands, or for any purpose where they come into direct contact with food."
