- Physical Description: N,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. Source: CAMEO Chemicals

- First Aid: Excerpt from ERG Guide 153 [Substances - Toxic and/or Corrosive (Combustible)]:; Refer to the "General First Aid" section. Specific First Aid: For corrosives, in case of contact, immediately flush skin or eyes with running water for at least 30 minutes. Additional flushing may be required. Removal of solidified molten material from skin requires medical assistance. (ERG, 2024) Source: CAMEO Chemicals
