PROBLEM TO BE SOLVED: To obtain a block-like metallic soap without deteriorating functions as a lubricant and without being broken at the time of production and use. SOLUTION: This block-like metallic soap is obtained by compounding a metallic salt of a higher fatty acid with another metallic salt of a higher fatty acid having a number of straight-chain carbon atoms different from that of the metallic salt of the fatty acid in the blocklike metallic soap comprising the metallic salt of the higher fatty acid as a principal component. When the metal forming the metallic salt of the higher fatty acid is an alkaline earth metal, stepwise solidification can be carried out even when the cooling rate of a metallic mold is raised. When the metal forming the other metallic salt of the fatty acid is of the same kind as that of the metal forming the metallic salt of the higher fatty acid which is the principal component, the affinity of the mixture is raised to provide the block-like metallic soap better in mechanical strength. |
