Abstract: An object is to provide a wax dispersant capable of improving the resin composition in the fluidity in a molten state, the transparency and the storage stability, when adding the wax to a thermoplastic resin. The wax dispersant is a copolymer (A) which has a copolymerization composition comprising structural units respectively derived from: an aromatic monomer (A1) within 40 to 94% by mass; a (meth)acrylic acid long chain alkyl ester (A2) represented by the formula (1) (an alcohol residue R2 is C9 to C22 alkyl) within 5 to 40% by mass; and a (meth)acrylic acid alkyl ester (A3) represented by the formula (2) (an alcohol residue R4 is C1 to C8 alkyl) within 1 to 20% by mass, and also has a weight average molecular weight within 3,000 to 50,000.

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.

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.
