Why is silica used in toothpaste?
Silica has two important roles in toothpaste. One role is to clean your teeth, dental abrasives remove the pellicle layer on the enamel exposing the stain and abrade it away. The second role is thickening, dental silica thickeners help create a matrix in toothpaste that helps with smooth mouth feel, viscosity, and reduced water loss.
How does ZEODENT® thickening silica work?
ZEODENT® thickening silica works by building a cohesive matrix with the hydrocolloids (gums) in the formulation. This matrix helps reduce water loss and stabilize viscosity of the toothpaste over time. Thickening silica also gives a smooth mouth feel to the toothpaste that is pleasing to consumers. Thickening silica also helps with formulation aesthetics by decreasing stringiness so that the customer has a clean break when applying the toothpaste ribbon to their toothbrush. Currently Evonik has two precipitated dental thickeners ZEODENT® 165 and ZEODENT® 153. Ask our experts which one will be right for your application.
Why is silica beneficial to oral health?
Dental silica, ZEODENT®, has a range of cleaning levels. Evonik creates dental silicas with gentle cleaning for sensitive or children’s toothpaste to strong cleaning for whitening toothpaste and everything in between. Even with Evonik’s strong dental cleaners there is no risk to scratching the enamel or eroding the dentin. It has better purity so there is less interaction with actives in the formulation, making the actives more available in the mouth. ZEODENT® also has optical properties if you are looking to make a gel or add a stripe to your toothpaste formulation.
How do I know my toothpaste formulation whitens?
To know if your formulation whitens it needs to be tested at a third-party testing facility for PCR (pellicle cleaning ratio). this will give you the best approximation for whitening of your formulation. At Evonik, our experts can give you formulation guides to help you achieve the cleaning you desire. Evonik has tested our abrasive silicas for PCR and can give you a range of dental silica needed in your formulation to achieve the industry standard of “Whitening”. According to research PCR above 90 is considered a whitening toothpaste.
