Abstract
Abstract Preparation of a dentifrice composition containing an insolubilized salt of 1,6-di-(p-chlorophenyl biguanido) hexane antimicrobial agent such as the disarcosinate monomeric salt or monofluorophosphate polymeric salt. The insolubilized salt may be pre-formed or formed in situ in the dentifrice composition. The insolubilized material is antimicrobially effective and provides desirable cosmetic effect.
