Abstract: This invention provides a water-reducible oil paint, capable of maintaining a stable suspension of coloring pigment during storage, and having the mechanical, coloring and drying properties of a traditional oil paint and methods for making same. The oil paint comprises a pigment, a base gel composition and an emulsifier-amine soap composition; the base gel composition comprises a traditional drying or semi-drying oil or oil acid, a nonionic or mixed nonionic-anionic emulsifier, having an HLB value in the range of from about 8 to about 18, and a thixotropic gel stabilizer; the emulsifier-amine soap compositon comprises at least one amine soap of an acid, selected from mono- and di-unsaturated drying oil acids, and a nonionic or mixed nonionic-anionic emulsifier. In another embodiment of the invention, the oil paint comprises at least one pigment, a complementary stabilizer, an emulsifier, a polymeric dispersant, a traditional stabilizer, optionally a wetting agent, and a drying oil.
