Abstract: A striped dentifrice stable color bleeding, wherein at least one component contains a colorant entrained in the matrix of substantially non-fracturable, partially cross-linked melamine-urea-formaldehyde condensation polymer particles, whereby on storage the colorant does not bleed any color into any other dentifrice component. The dentifrice may also contain a formaldehyde scavenger to bind-up any formaldehyde released from the particles.

Abstract: An aqueous dentifrice composition comprising an aqueous vehicle containing at least two active ingredients reactive with each other, at least one of the active ingredients being encapsulated in a substantially water immiscible, pressure rupturable shell which is rupturable during use of the dentifrice, causing the same to be released for interaction with the other active ingredient, the shell being formed from a plasticized alkyl cellulose polymer. The dentifrice exhibits increased efficacy for fluoridation of teeth when the active ingredients are soluble fluoride salt and a calcium salt encapsulated in the plasticized alkyl cellulose polymer.

Abstract: 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.
