TolueneCAS 108-88-3
Common paint and lacquer solvent — neurotoxic, ototoxic, and a confirmed developmental hazard.
Toxic Chemical Databases
Substance-specific listings — these flags are for Toluene alone, not for the broader family.
Chemical Type
Aromatic Hydrocarbon Solvent
Chemical Description
Toluene is benzene with a methyl substituent — less carcinogenic than benzene but still a serious neurotoxin and a confirmed developmental hazard in humans (fetal solvent syndrome is documented in chronic-exposure mothers). Used as a paint solvent, lacquer thinner, and contact-cement carrier. NIOSH identifies toluene as ototoxic at chronic levels — combined exposure to toluene and workplace noise causes more hearing loss than either alone. Chronic exposure also causes color-vision deficits and slowed reaction time.
Biological Activity
Severity scores specific to this substance, NOT the parent family average. Differences between siblings are real and meaningful.
Top Health Consequences
- Central nervous system toxicity (acute and chronic)
- Fetal solvent syndrome — irreversible developmental damage
- Ototoxicity, especially combined with workplace noise
- Color-vision deficits at chronic occupational exposure
- Liver enzyme elevation in chronic exposure
Pathways of Exposure
- Inhalation during paint, stain, and adhesive application
- Off-gassing during cure window for solvent-based products
- Dermal contact during contact-cement application
