Metal naphthenates are salts of these naphthenic acids1 having the formula M(Naphthenate)2.2 They can be found naturally from the combination of naphthenic acids in crude oil with metal ions contained in water.
These naphthenate salts are soluble in certain organic carrier liquids and are an effective source of metal ions in organic media. Traditional applications2 include use in paint drying, wood treatment, anti-fouling agents, detergents, insecticides, fungicides, wetting agents, lubricants, surfactants, and corrosion inhibitors.
