2,2-Dimethylpropane

CAS RN: 463-82-1

Range of Toxicity

A) TOXICITY: Toxic dose is not established. A single swallow of a hydrocarbon with low viscosity and high volatility can cause pneumonitis if aspirated. Significant systemic toxicity (CNS, renal, hepatic, bone marrow) has been described after exposure to trichloroethane, trichloroethylene, carbon tetrachloride, methylene chloride, and petroleum distillates, or hydrocarbons with toxic additives (eg, pesticides, heavy metals, nitrobenzene, aniline).
B) The following compounds are unlikely to produce systemic symptoms following accidental ingestion: gasoline, kerosene, charcoal lighter fluid, petroleum ether (benzine), petroleum naphtha, VM and P naphtha paint thinner, mineral spirits (eg, Stoddard solvent, white spirit, mineral turpentine, petroleum spirits), turpentine, and aromatic hydrocarbons (xylene, toluene).
C) The following hydrocarbons are not associated with systemic toxicity, but they have the highest risk of severe aspiration pneumonitis: mineral seal oil, signal oil, oils found in furniture polish, or oil polishes.
D) The following generally do not cause CNS or pulmonary problems. They are generally considered nontoxic, although with frank aspiration (very rare) they may cause a low grade lipoid pneumonia: asphalt or tar, lubricants (eg, motor oil, transmission oil, cutting oil, household oil, heavy greases), mineral oil or liquid petrolatum (eg, laxatives, baby oil, suntan oil, white petroleum).
