    Formaldehyde is classified as a human carcinogen (Category 1) by IARC and a Category 1B carcinogen by ECHA due to its reactivity and potential health effects.

  • 2

    Formaldehyde releasers are substances that release formaldehyde upon decomposition and are assumed to have similar effects as formaldehyde itself.

  • 3

    The MAK Commission derived specific MAK values for formaldehyde releasers based on inhalation data, hydrolysis rates, and formaldehyde release rates.

  • 4

    TMAD and EDAO were classified as Carcinogen Category 4, with MAK values derived from substance-specific inhalation studies and analogies to formaldehyde.

  • 5

    THT's carcinogen classification may not be protective enough, as studies indicated significant adverse effects on the respiratory tract.
