  • the color particles were well preserved as such; the surrounding toothpaste base showed no visible bleeding.
  • the paint particles were easy to rub and therefore suitable for the application described above.
  • the color particles were placed in water (1 g in 20 ml of water) and rated after one week. The color particles had turned into a cloudy mass and were no longer perceptible as particles.
  • the color particles were produced as described in Example 3.
  • the color particles were applied in various toothpaste bases in a dosage of 1% by weight, stored at 45 ° C. and assessed after three weeks.
  • Three toothpaste bases (silica base, carbonate base, gel base), which were prepared as described in Examples 2 to 4, served as toothpaste bases.
  • the starch powders were each made up as a 10% suspension in water at room temperature.
  • the viscosity of the starch has an influence on the stability of the color particles during use.
  • the viscosity of the starch used is preferably from 10 mPa s to 50,000 mPa s, measured as a 10% strength solution in water at 90.degree.
