Process for the preparation of microcapsules

The present invention relates to a one-shell aminoplast core-shell microcapsule stabilized by a polyisocyanate. It also provides a method for stabilizing aminoplast microcapsules in liquid aqueous surfactant-rich consumer products.

Process for preparing polyurea microcapsules

The present invention relates to a process for producing microcapsules with a polyurea wall, as well as to the microcapsules themselves and consumer products comprising these microcapsules. The process of the invention uses 3,5-diamino-1,2,4-triazole as a specific polyamine for forming the wall with the polyisocyanate.

The present invention relates to a process for producing perfume-containing microcapsules with a polyurea wall that can be used in home or personal care products, as well as to the microcapsules themselves and consumer products that contain these microcapsules. The process of the invention uses a combination of aromatic and aliphatic polyisocyanates in specific relative concentrations.
