Toxicity Profile
Route of ExposureOral (6) ; inhalation (6) ; dermal (6)
Mechanism of ToxicityBronidox likely acts as an oxidizing agent that leads to oxidation of free sulfhydryls in essential enzymes. One of the most probable protein targets is the TRPA1 ion channel that is expressed in sensory nerves (trigeminal nerve) of the eyes, nose, mouth and lungs. This compromises their activity and can lead to cell damage, cell death and/or apoptosis. It may also react with amines and amides to form nitrosamines or nitrosamides. Nitrosamines can be carcinogenic.
MetabolismBronidox can be metabolized to 2-bromo-2-nitropropane-1,3-diol, a well known nitrosating agent.(6)
Toxicity ValuesLD50: 590 mg/kg (mouse, Oral); LD50: 455 mg/kg (rat, Oral) LD50: 31 mg/kg (rat, ipr.); LD50: 2500 µg (mouse, skin); LD50: 2500 µg (rat, skin)
Lethal DoseNot Available
Carcinogenicity (IARC Classification)No indication of carcinogenicity (not listed by IARC). (7)
Uses/SourcesBronidox is used as a stabilizer, surfacant, bactericide, and preservative in immunology and cosmetics. (4)
Minimum Risk LevelNot Available
Health EffectsCan cause significant skin and eye irritation at concentrations >0.1%. A formaldehyde releaser, bromonitrodioxane can cause allergic contact dermatitis in hairdressers and in workers handling cleaners containing bromonitrodioxane. It is neither mutagenic nor teratogenic.
SymptomsAcute doses cause skin and eye irritation. May cause respiratory tract and mucous membrane irritation if inhaled. Harmful if ingested. May affect behavior/central nervous system (tremor, convulsions, excitement).
TreatmentEYES: irrigate opened eyes for several minutes under running water. INGESTION: do not induce vomiting. Rinse mouth with water (never give anything by mouth to an unconscious person). Seek immediate medical advice. SKIN: should be treated immediately by rinsing the affected parts in cold running water for at least 15 minutes, followed by thorough washing with soap and water. If necessary, the person should shower and change contaminated clothing and shoes, and then must seek medical attention. INHALATION: supply fresh air. If required provide artificial respiration.

General Function:
Temperature-gated cation channel activity
Specific Function:
Receptor-activated non-selective cation channel involved in detection of pain and possibly also in cold perception and inner ear function (PubMed:25389312, PubMed:25855297). Has a central role in the pain response to endogenous inflammatory mediators and to a diverse array of volatile irritants, such as mustard oil, cinnamaldehyde, garlic and acrolein, an irritant from tears gas and vehicule exhaust fumes (PubMed:25389312, PubMed:20547126). Is also activated by menthol (in vitro)(PubMed:25389312). Acts also as a ionotropic cannabinoid receptor by being activated by delta(9)-tetrahydrocannabinol (THC), the psychoactive component of marijuana (PubMed:25389312). May be a component for the mechanosensitive transduction channel of hair cells in inner ear, thereby participating in the perception of sounds. Probably operated by a phosphatidylinositol second messenger system (By similarity).
