Safety

CIR Status
Insufficient data
Sensitization risk High

Formaldehyde, released by this compound, is classified as Carcinogen Category 4 by SCCS due to its potential to cause nasal tumors at concentrations exceeding detoxification capacity. The ingredient itself is noted to be highly irritating and corrosive to both skin and eyes, and a significant irritant to the respiratory tract. Company classifications further describe it as potentially fatal if inhaled and capable of causing severe skin burns, eye damage, and organ damage with prolonged or repeated exposure. Evidenced by positive sensitization reactions reported at a 1% concentration, indicating a high risk of allergic skin reactions. It is crucial to note that this substance is not intended for use in consumer products, significantly limiting consumer exposure.
