Abstract

The present invention relates to functional composite particles for the oral care sector, more particularly for toothpastes and mouthwashes, which are charged with active ingredients which ensure a long-term antimicrobial or antibacterial effect in the oral cavity and hence reduce the formation of plaque and halitosis. The invention further relates to a process for producing these composite particles and also to their use for producing oral hygiene articles.
