Abstract

We tested six brands of tarter control gel toothpastes with the TA.XTPlus Texture Analyzer to measure how toothpaste’s firmness, stringiness, and adhesiveness change when exposed to air. We all experience this change in texture when others fail to replace the toothpaste tube’s cap. The tarter control gels tested included Colgate, Aim, CVS brand, Arm & Hammer, Listerine, and Crest. The tarter control gels were tested at four intervals after extrusion: immediately, thirty minutes, sixty minutes and sixteen hours.
