Pale yellow chunky solid or a light yellow viscous liquid (at 150.1°F). Isopropyl alcohol-like odor. A quaternary ammonium salt of formula (R2(CH3)2N).O2SOCH3 where R represents saturated long-chain alkyl groups derived from fatty acids (groups such as C16H33 or C18H37).
Quaternary ammonium compounds, bis(hydrogenated tallow alkyl)dimethyl, Me sulfates may may react vigorously with strong oxidizing agents and with strong reducing agents. May generate heat with acids.
ACUTE/CHRONIC HAZARDS: Materials soaked with Quaternary ammonium compounds, bis(hydrogenated tallow alkyl)dimethyl, Me sulfates may spontaneously combust.
Quaternary ammonium compounds, bis(hydrogenated tallow alkyl)dimethyl, Me sulfates is combustible.
