Abstract

A dental care composition for the prophylactic dental hygiene (prophylactic paste) comprises as principal components the following: from 10 to 80% by weight, preferably from 35 to 55% by weight, of a polishing body containing plate shaped rock particles, preferably perlite particles; from 20 to 80% by weight, preferably from 40 to 50% by weight, of a nonionic, preferably polymeric surface active agent; and from 0 to 20% by weight, preferably from 1 to 10% by weight, of an emulsifier or emulsifier blend. Polyethylene glycols (Macrogol) having molecular weights of from 200 to 1,000, preferably of from 200 to 600, are particularly suited as pure compounds or as a blend of different variants having different molecular weights. The dental care composition shows a smooth and soft consistency and has only a weak tendency of being splashed during its application in the mouth.
