Hazard InformationBack Directory
【General Description】

White to pale yellow paste or liquid with a mild odor. Sinks and mixes with water.
【Reactivity Profile】

DODECYL SULFATE is incompatible with strong oxidizers. DODECYL SULFATE, [SODIUM SALT](151-21-3) 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.
【Air & Water Reactions】

Insoluble in water.
【Health Hazard】

Inhalation of dust causes sneezing and coughing. Ingestion of large amounts causes irritation of stomach. Dust irritates eyes and may cause burns on prolonged contact. Contact with skin causes some irritation; continued exposure to water solution causes drying out and cracking.
【Fire Hazard】

Flash point data for this chemical are not available; however, DODECYL SULFATE, [SODIUM SALT] is probably combustible.
