Physical DescriptionN,n-dimethyl-1-octadecanamine appears as a clear yellow liquid with a fishlike odor. Insoluble in water and less dense than water. Hence floats on water. Contact may irritate skin, eyes and mucous membranes. May be toxic by ingestion, inhalation or skin absorption. Used to make other chemicals.CBIOther Solidmp = 22.89 deg C[ChemIDplus] Clear yellow liquid with a fishy odor[CAMEO] Colorless to yellow liquidClear or slightly cloudy with a fishy odor[MSDSonline]
