Abstract

This article briefly outlines the evolution of metal soaps over the years from an art form to a reliable quality raw material. Methods of manufacture and the analytical tests utilized to ensure specificity of properties are described. Also included are tables indicating the volume of the various carboxylates manufactured and figures on the individual metals produced. A general description of the health and safety factors associated with these products is provided.

In application the specific metals and the attributes they provide are stated. Emphasis is placed on their use as driers for paint and printing inks as well as heat stabilizers and lubricants in plastics. Governmental legislation responding to environmental pressures has promoted the development of new technologies, yet metal soaps still remain an integral ingredient in coatings.
