ABSTRACT:
A polyurethane composition containing (A) a urethane compound obtained by reacting 100 parts by weight of a polyol with a polyisocyanate such that the NCO/OH equivalent weight ratio is greater than 0.5 but smaller than 15, and (B) a compound selected from a linear olefin compound having at least 6 carbon atoms, an oligomer of a linear olefin compound having at least 6 carbon atoms or an epoxy compound of an oligomer of a linear olefin compound having at least 6 carbon atoms, wherein the content of said compound (B) per 100 parts by weight of said polyol is greater than 5 parts by weight but smaller than 400 parts by weight. This composition is a composition with no suspicions that it contains an endocrine-disrupting chemical.
