PROPIONATE ENHANCES TRAVEL TOOTHBRUSHES

Comments Email Print

Trisa AG injection molds a traveler's toothbrush that contains its own toothpaste in the handle. The consumer manually pumps the toothpaste to penetrate the bristles.

The Triengen, Switzerland, firm chose Tenite propionate resin from Eastman Chemical Co. of Kingsport, Tenn., for the body and neck of its DentXpress toothbrush. The resin resists toothpaste chemicals, and provides stiffness and a variety of color options.
