Patent granted for oral care composition with fluoride and silica
A recently granted patent (Publication Number: US11883511B2) discloses an innovative oral care composition designed to enhance oral health. The composition includes an orally acceptable vehicle, a thickening silica, and a fluoride ion source, with the fluoride being absorbed on the thickening silica. The thickening silica used in the composition has specific characteristics, including a particle size distribution (D95) of less than or equal to 7 µm and a BET surface area of greater than or equal to 150 m2/g. The pH of the composition is maintained below 5.5 to ensure efficacy. The fluoride ion source can be selected from various options such as sodium fluoride, stannous fluoride, and potassium fluoride, among others. Importantly, the release of fluoride from the composition plateaus at approximately 400 seconds when measured at 24°C.
Furthermore, the patent claims cover various aspects of the oral care composition, including the specific properties of the thickening silica, the amount of fluoride absorbed on the silica, and the pH range of the composition. The composition aims to address multiple oral health issues such as reducing dental caries, inhibiting plaque formation, promoting remineralization of teeth, and reducing hypersensitivity. The method of application involves applying the oral care composition to the oral cavity to achieve the desired benefits. The patent also specifies the types of products the composition can be used in, such as toothpaste, gel, toothpowder, and dental varnish. Overall, the patented oral care composition offers a unique combination of ingredients and properties to improve oral health outcomes effectively.
