CarCareTruth tracks o-Dichlorobenzene (CAS 95-50-1) as a car-care ingredient. It is classified as a VOC.
Moderate acute toxicity by inhalation and ingestion (H302, H332). Skin irritant (H315), eye irritant (H319), and respiratory irritant (H335) at occupational exposure levels. OSHA PEL ceiling 300 mg/m³. ACGIH TLV-TWA 25 ppm. Not currently Prop 65 listed but subject to SARA 313 reporting.
1,2-Dichlorobenzene (o-dichlorobenzene, o-DCB) is a chlorinated aromatic solvent. It is a liquid at room temperature, denser than water (SG ~1.3), and miscible with most organic solvents. In automotive additive formulations its role is typically as a co-solvent or carrier for other active components. At occupational exposure levels it is a respiratory and skin irritant; at high concentrations it causes CNS effects. It is listed under EPA SARA Section 313 for environmental release reporting. Aquatic toxicity is significant at concentrations above 1–10 mg/L in surface water. The compound is moderately persistent and bioaccumulates in aquatic organisms.
