Prevention of dye-bleeding and transfer during laundering

A striped dentrifrice 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.

Dental hemostatic composition

The present invention is directed towards microcapsules, uses and methods of microencapsulation with improved properties regarding agglomeration, bleeding and control of the reaction. The invention is especially suitable for chemical compounds with at least one carboxamide group, preferably for microencapsulation of those compounds wherein the carbonyl group is attached to a nitrogen atom or nitrogenated heterocycle and wherein the microencapsulation reaction may be too vigorous. The microcapsules are characterized by a mixed glycoluril-polyurea polymer wall, wherein the polyurea groups come from a urea-formaldehyde resin and not from isocyanate monomers or prepolymers. The process of making such microcapsules a dispersant in the oil phase of the type of block copolymer of vinylpyrrolidone/vinylalkene and/or vinylpyrrolidone/vinyl acetate and the microencapsulation reaction may be carried out without the presence of any polyamine/polyol acting as a catalyst.
