According to the present invention, there are provided microcapsules comprising an emulsion droplet encapsulated by a metallic film, wherein the emulsion droplet comprises an emulsifier disposed around a liquid core material. The present invention also provides processes for preparing the microcapsules, as well as formulations comprising the same. The present invention further provides for certain consumer products comprising: an adjunct material; and a plurality of microcapsules, said microcapsules comprising: an emulsion droplet encapsulated by a metallic film, wherein the emulsion droplet comprises an emulsifier disposed around a liquid core material.

Microcapsules and compositions providing controlled release of actives

Consumer products including compositions that include coated microcapsules, said coated microcapsules including a polymeric shell and a liquid core material encapsulated therein; and a metallic coating surrounding said microcapsules and methods related thereto.

Compositions providing delayed release of actives

Accordingly, there are provided coated microcapsules including: a microcapsule including a polymeric shell and a liquid core material encapsulated therein; and a metallic coating surrounding said microcapsule, wherein the metallic coating comprises particles of a first metal adsorbed on said polymeric shell and a film of a second metal formed thereon; wherein said particles of the first metal are charge-stabilized nanoparticles; processes for preparing the coated microcapsules, as well as formulations related thereto are also included.

Coated microcapsules

Accordingly, there are provided coated microcapsules including: a microcapsule including a polymeric shell and a liquid core material encapsulated therein; and a metallic coating surrounding said microcapsule, wherein the metallic coating includes particles of a first metal adsorbed on said polymeric shell and a film of a second metal formed thereon; wherein the particles of the first metal are sterically-stabilized nanoparticles; processes for preparing the coated microcapsules, as well as formulations related thereto are also provided.

Accordingly, there are provided coated microcapsules including a microcapsule, said microcapsules including a polymeric shell and a liquid core material encapsulated therein; and a metallic coating surrounding said microcapsules; wherein the metallic coating includes particles of a first metal adsorbed on said polymeric shell and a film of a second metal formed thereon; and wherein the metallic coating has a maximum thickness of 1000 nm; and methods and formulations related thereto.

Accordingly, there are provided coated microcapsules including: a microcapsule including a polymeric shell and a liquid core material encapsulated therein; and a metallic coating surrounding said microcapsule, wherein the metallic coating includes particles of a first metal adsorbed on said polymeric shell and a film of a second metal formed thereon; wherein the particles of the first metal are adsorbed on said polymeric shell by contacting the polymeric shell with a reducing agent and a solution comprising ions of the first metal, thereby reducing said ions and forming particles of the first metal adsorbed on said polymeric shell; method and formulations related thereto are also provided.
