Composition, thermoplastic resin composition using same, and molded article of same

A thermoplastic resin composition, comprising:

• a thermoplastic resin;
• (A) a cyclic organophosphate aluminum salt;
• (B) a sodium carboxylate;
• and
• (C) a fatty acid metal salt,
• wherein the (A) cyclic organophosphate aluminum salt is aluminum hydroxybis[2,2′-methylene-bis(4,6-di-tert-butylphenyl)phosphate],
• wherein the (B) sodium carboxylate is at least one selected from the group consisting of a sodium aromatic carboxylate and a sodium-fatty acid having 10 to 21 carbon atoms,
• wherein the (C) fatty acid metal salt is represented by the following Formula (2):
• wherein R6 represents a group which is introduced to an aliphatic organic acid having 10 to 30 carbon atoms, and M1 represents lithium or potassium,
• wherein a molar ratio of the (C) fatty acid metal salt to the (B) sodium carboxylate, (C),/(B), is in a range of 0.30 to 5.00, and
• wherein a molar ratio of the (A) cyclic organophosphate aluminum salt to the (B) sodium carboxylate and the (C) fatty acid metal salt, (A)/{(B)+(C)}, is in a range of 0.15 to 0.70.
