Radical reaction inhibitors, method for inhibition of radical reactions, and use thereof

摘要

The present invention has an object to provide a radical reaction inhibitory agent for inhibiting unsaturated compounds from decomposing through radical reactions, a method for inhibiting the formation of free radicals from unsaturated compounds and radical reactions thereof, and a composition which is suppressed in radical formation, radical reaction, or progress thereof. The object is solved by establishing a radical reaction inhibitory agent containing as an effective ingredient cyclotetrasaccharide or a mixture of cyclotetrasaccharide and its saccharide derivative(s), a method for inhibiting the formation of free radicals from unsaturated compounds and radical reactions thereof, and a composition which contains the agent and which is suppressed in radical formation, radical reaction, or progress thereof.
