A striped dentifrice stable to color bleeding, wherein at least one dentifrice component contains a colorant entrained in a matrix of synthetic wax particles having a melting point range as measured by DSC is between about 40 ~C and about 135 ~C and the peak endotherm temperature is at least about 65 ~C, whereby on storage no off-taste is detected in the dentifrice nor is there any observable colorant bleeding into any other dentifrice component.

L'invention concerne un dentifrice à bandes de couleur stabilisé pour éviter l'étalement des couleurs, dans lequel au moins un constituant a un colorant occlus dans une matrice de particules de cire artificielle dont le point de fusion est compris entre environ 40· C et environ 135· C (mesure par analyse enthalpique différentielle) et dont la température endothermique de pointe est au moins égale à 65· C environ. Dans ces conditions, le stockage du produit n'entraîne ni dénaturation organoleptique détectable ni bavure de couleur observable d'un constituant sur l'autre.
