ABSTRACT:
Disclosed is a makeup material for human use containing a shape memory polymer shaped into fine spheres. The shape memory polymer used is a polyurethane that is obtained by polymerizing with the prepolymer method a composition of a bifunctional diisocyanate, a bifunctional polyol, and a bifunctional chain extender with active hydrogen groups in the mole ratio of diisocyanate:polyol:chain extender=2.00-1.10:1.00:1.00-0.10. The polyurethane is preferred to have approximately equal amounts of NCO groups and OH groups at its ends, and a glass transition point above the human body temperature, and a crystallinity value between 3 to 50 wt %.
