Title:
MARINE BIODEGRADATION PROMOTER HAVING HYDROCARBON GROUP, AND MARINE BIODEGRADABLE COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2023/100257
Kind Code:
A1
Abstract:
Provided is a marine biodegradation promoter that is a hydrophobic, thermoplastic powder composed of a compound in which ionic bonds bond a metal cation having a valence of two or higher and a monovalent organic anion derived from a substance selected from among monovalent carboxylic acids containing a monovalent hydrocarbon group having 10-25 carbon atoms, monovalent sulfonic acids containing a monovalent hydrocarbon group having 10-25 carbon atoms, monovalent sulfate esters containing a monovalent hydrocarbon group having 10-25 carbon atoms, and monovalent phosphate esters containing a monovalent hydrocarbon group having 10-25 carbon atoms, wherein the powder dissolves in a 3 mass% aqueous sodium chloride solution, or exhibits hydrophilicity in a 3 mass% aqueous sodium chloride solution.
