Huber’s Silica Thickener Products
The rheological properties of dentifrice applications are critical in the manufacture/filling of toothpastes, and to long term stability and key consumer attributes and aesthetics. Huber Zeodent® thickeners can be used to develop the optimum rheological profile to support production and drive consumer preference for a toothpaste product. Dependent upon a customer’s need, Huber thickeners can be used from 2 to 12 percent to provide the desired viscosity. These thickeners are also compatible with commonly used organic hydrocolloids. Huber thickener products deliver over the entire range of rheological properties. Viscosity is a key predictor of long term product stability.
Stability is dependent on the formulation as a whole and is influenced by all of the toothpaste ingredients. A constant rheological profile over time and no syneresis (liquid separation) is the ideal combination that toothpaste formulators attempt to achieve. When using Zeodent dental cleaning silicas and thickeners in toothpaste, excellent storage stability critical for long product shelf life can be achieved (see graph below). When properly formulated, toothpaste products with Zeodent thickeners show no sign of liquid separation even after storage up to 50°C for long periods of time. In all cases, Zeodent silica-based formulations have proven to be stable with no long term change in the toothpaste properties once equilibrium has been achieved.
