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.

Composite particles for use in oral hygiene

A silica comprising at least two silica fractions, wherein the at least two silica fractions differ by at least 10% in at least one of their BET surface area values, their CTAB surface area values or their DBP absorption values, the ranges of these three physicochemical properties being as follows:

Inhomogeneous silicas in dental care compositions

Paper containing a filler which is synthetic silica, which can be precipitated, spray-dried and ground. The synthetic silica reduces show through.
