  • Publication number: 20160046785
    Abstract: Metallic soap compositions for use in various applications, including as adhesives, as having anti-corrosion properties on certain surfaces or materials, and as asphalt modifiers to reduce viscosity in an asphalt mixture, and process for making the same, are disclosed. The processes comprise at least a partial saponification of a mixture of an oil, often a natural oil which may be hydrogenated and/or metathesized, and a metal compound via a fusion process, or may comprise at least a partial saponification of a mixture of a similar oil and a metal compound, or optionally a fatty acid derived from a similar oil, via an aqueous process, with an optional addition of an inorganic metal salt via at least one ion exchange reaction.
