    ca. 150 g/L (20 ºC)

    Toxicity:

    LD50 orally in rats: 1288 mg/kg (Walker)

    Odor:

    Slight fatty odour

    PH:

    Air and Water Reactions:

    Insoluble in water.

    Reactivity Profile:

    DODECYL SULFATE is incompatible with strong oxidizers. Sodium dodecyl sulfate is also incompatible with cationic materials and with acids with pH below 2.5. Salts, basic, such as DODECYL SULFATE, are generally soluble in water. The resulting solutions contain moderate concentrations of hydroxide ions and have pH's greater than 7.0. They react as bases to neutralize acids. These neutralizations generate heat, but less or far less than is generated by neutralization of the bases in reactivity group 10 (Bases) and the neutralization of amines. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible.

    Critical Temperature & Pressure:

    2-8°C
