metal soaps some of the major role

 Metal soap a metal other than an alkali metal , a metal oxide or salt and a fatty acid , rosin acid , naphthenic acid soap derived role .
Metallic soap can not be direct saponification of fats , sodium fatty acid soap and are based on the  acrylic processing corresponding metal salt solution was prepared by metathesis reaction , also useful for fatty acid and metal powder obtained melting method , but the quality is not high. Common metallic soap of calcium , magnesium, zinc , lead, aluminum , manganese, iron , cobalt , nickel, molybdenum , barium , cadmium and so on. Generally insoluble in water, insoluble in ethanol most , some can be dissolved in turpentine or ligroin , some can be dispersed in the other organic solvents or drying oil .
Mainly used in paint industry and the plastics industry , mainly in the coatings industry as oil-based paints , coatings and  titanium dioxide anatase alkyd paints phenolic driers . In the plastics industry , can be used as stabilizers. In addition, also for the preparation of greases , waterproofing agents , preservatives , cosmetics and pharmaceutical products. Where the use of metal soap formed by metal salts and organic fertilizer can construct Wong . But as a general alkali metal soaps are dissolved in water , washed our common soap is such a case . And the other is an alkaline earth metal and heavy metal soaps generated , are not soluble in water, but soluble in organic solvent , referred to herein metallic soap , soap entails in terms of the latter category . Metallic soaps very wide range of applications , this is really special because it has a relatively structural reason. Metal soap a metal other than an alkali metal , a metal oxide or salt and a fatty acid , rosin acid , naphthenic acid soap derived role .

Mainly used in paint industry and the plastics industry , mainly in the coatings industry as oil-based paints , coatings and alkyd paints phenolic driers . In the plastics industry , can be used as stabilizers. In addition, also for the preparation of greases , waterproofing agents , preservatives , cosmetics and pharmaceutical products.
