质构仪牙膏挤压装置

In toothpaste manufacture three characteristics of importance in consumer acceptance are absence of lumps or graininess, absence of air bubbles, and the proper consistency. All of these are greatly influenced by the manufacturing procedure and its control, and the selection of raw ingredients.

In terms of consistency the binders play a very important role. The purpose of the binder is to hold all of the ingredients of a paste together and to provide the proper consistency and texture. It is desirable that a toothpaste be easily squeezed out of the tube, break off cleanly when the desired amount has been extruded, but should not be so soft as to sink quickly into the brush.

This imitative test indicates the ease of extrusion of toothpaste as a result of the product formulation or the extrusion temperature.
