HIGH-FLUORIDE ORAL CARE COMPOSITION AND METHOD FOR MAINTAINING ANTI-CARIES ACTIVITY Russian patent published in 2014 - IPC A61K8/19 A61K8/21 A61K8/73 A61Q11/00 

FIELD: medicine, pharmaceutics.

SUBSTANCE: group of inventions refers to oral care compositions and a method for maintaining the fluoride ion activity in such compositions. The presented composition contains a fluoride ion source in an amount adequate to provide at least 2,500 portions per one million fluoride ions, the effective amount of a desensitising agent (potassium nitrate), at least 40 wt % water and a humidifying agent. A version of the composition contains at least 2,500 portions per one million fluoride ions, potassium nitrate 5 wt % to 10 wt %; water 40 wt % to 75 wt %; hydrocolloid 0.5 wt % to 15 wt % specified in a group consisting of xanthan gum, carrageenan and a combination thereof; and a humidifying agent. The method for maintaining the fluoride ion activity of the oral care composition involves introducing into the composition containing at least 5,000 portions per one million fluoride ions, an effective amount of the desensitising agent (potassium nitrate), at least 40 wt % water and the humidifying agent, hydrocolloid in the amount of 0.5 wt % to 15 wt %.

EFFECT: implementing the group of inventions provides maintaining the fluoride ion anti-caries activity in the composition containing high concentration of fluoride ions, an effective amount of potassium nitrate and water.
