Toxicity Profile
Route of ExposureOral (3) ; inhalation (3) ; dermal (4)
Mechanism of ToxicityWhile quaternium-10 itself is not toxic, it is a nitrosating agent. Nitrosating agents may decompose and/or react to cause nitrosamine contamination. Nitrosamines are produced from secondary amines and amides in the presence of nitrite ions and are believed to be carcinogenic. Once in the body, nitrosamines are activated by cytochrome P-450 enzymes. They are then believed to induce their carcinogenic effects by forming DNA adducts at the N- and O-atoms. (4, 5, 1, 2, 3)
MetabolismNitrosamines can enter the body via ingestion, inhalation, or dermal contact. Once in the body, nitrosamines are metabolized by cytochrome P-450 enzymes, which essentially activates them into carcinogens. (1, 2)
Toxicity ValuesNot Available
Lethal DoseNot Available
Carcinogenicity (IARC Classification)Not listed by IARC. Certain nitrosamines are classified by IARC as either probably or possibly carcinogenic to humans (Groups 2A and 2B, respectively). (6)
