FIELD: medicine.
SUBSTANCE: group of inventions concerns oral care compositions. The presented compositions contain an amorphous silica abrasive having a particle size characterised by the fact that 90% of the particles have a particle size less than 50 mcm, and a fluoride source. One version of the composition also contains stannous ions and peroxide, and pH of the composition is less than 5. The use of amorphous silica with these characteristics provides improved fluoride stability and other active agents in the oral care composition. The compositions with pH lower than usual, e.g. falling within the range of 3.5 to 5 is allowed to be used.
EFFECT: using the presented compositions enables the effective and safe oral cleansing.
