 Potassium oleate (CAS NO.143-18-0) is also named as 9-Octadecenoic acid (Z)-, potassium salt ; Caswell No. 698B ; EPA Pesticide Chemical Code 079095 ; HSDB 5643 ; Oleic acid, potassium salt ; Potassium 9-octadecenoate, (Z)- ; Potassium cis-9-octadecenoate ; Potassium cis-9-octadecenoic acid ; Trenamine D-200 ; Trenamine D-201 ; UNII-74WHF607EU . Potassium oleate (CAS NO.143-18-0) is brown solid or clear to amber liquid with a soapy odor. It can sinks and mix slowly with water. Salts, basic, such as Potassium oleate , 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. Inhalation of dust causes irritation of nose and throat, coughing, and sneezing. Ingestion causes mild irritation of mouth and stomach. Contact with eyes causes irritation. Irritating vapors and toxic gases, such as carbon dioxide and carbon monoxide, may be formed when involved in fire.
