Carbopol® polymers can be used in oral care applications such as toothpastes and gels, desensitizing and whitening products. These polymers primarily function as efficient thickeners and co-binders at low usage levels in both aqueous and anhydrous systems. They provide suspension of non-soluble actives or excipients and are capable of thickening peroxide gel systems while maintaining product stability.
The viscoelastic structure of Carbopol polymers imparts shear-thinning rheology and low thixotropy which enables a clean ribbon of toothpaste to be extruded from the tube. These polymers:
