Abstract: A composition of zinc salts of carboxylic acids. The carboxylic acids of the zinc salts include 0.5 to 6.0 mass % of a component (A), 0.05 to 1.2 mass % of a component (B) and 88.0 to 98.0 mass % of a component (C) described below. A ratio [(A)/(B)] of a mass of the component (A) with respect to a mass of the component (B) is 99/1 to 75/25, where (A) is a straight chain and saturated carboxylic acid having a carbon number of 12 to 22; (B) is a strait chain and unsaturated carboxylic acid having one unsaturated bond and a carbon number of 18, said unsaturated bond comprising a trans-form double bond; and (C) is a straight-chain and unsaturated carboxylic acid having one unsaturated bond and a carbon number of 18, said unsaturated bond comprising a cis-form double bond.

Abstract: A method of manufacturing an iron soap is disclosed herein. The method comprising the steps of: reacting, at a temperature equal to or lower than a crystal transition initiation temperature of the iron soap to be manufactured, between a straight-chain saturated fatty acid alkali metal salt aqueous solution having from 12 to 22 carbons and a trivalent iron salt aqueous solution with pH of 0.1 to 5.5 so as to prepare an iron soap slurry; and adjusting pH of the prepared iron soap slurry to from 0.1 to 6.0.
