General description

Potassium oleate (PO), also known as oleic acid potassium salt, is an anionic surfactant characterized by a long hydrophobic hydrocarbon chain and a hydrophilic carboxylic acid end group. It is commonly utilized in organic synthesis as both a surfactant and an emulsifier.

Application

Potassium oleate can be used to synthesize uncoagulative oleic acid magnetic ultrafine particles.
