摘要:
Flavored chewable foams for the oral care sector are produced from a polyurethane-polyurea and a sensorially active substance (e.g., taste substance and/or aroma substance) by foaming a polyurethane-urea dispersion, drying that dispersion and incorporating the sensorially active substance into the polyurethane-urea dispersion before, during or after foaming of the dispersion.

摘要:
The present invention relates to a strand-like profile body for dental cleaning, wherein the cross-section of the profile body comprises a bottom section (10) and first wall sections (12) and second wall sections (14), which adjoin the bottom section and are arranged opposite of each other, and wherein furthermore the bottom section (10) together with the first and second wall sections (12, 14) forms at least one recess (16, 18) in the profile body for receiving a tooth. The invention further relates to a method for the production thereof and the use thereof for cleaning teeth.
