An ultra low density film and an ultra low density solid material are produced by the steps of providing a vessel, introducing two immiscible fluids into the vessel, adding nanocrystals to at least one of the two immiscible fluids, applying a shear force to the two immiscible fluids and the nanocrystals in a manner that causes the nanocrystals to self-assemble and form colloidosomes. The colloidosomes amass and evaporation of the two fluids produces dried colloidosomes. The ultra low density self-assembled colloidosomes are hollow self-assembled colloidosomes, which are formed into the ultra-low density film and the ultra-low density solid.

This invention relates to a process for colloidosome-type microcapsules elaboration from solid particles microcapsules obtained by ionic gelation. In the process, an (O/W) type emulsion is initially generated stabilized with the solid particles microcapsules, and then the particles are fixed to the interface by adsorption of polyelectrolytes, cross-linking, heat treatment or fatty coating, generating the colloidosome with the water-insoluble phase encapsulated in the core and covered by the shell particles.

The present invention relates to compositions comprising a hollow glucan particle or cell wall particle encapsulating a terpene component, methods of their manufacture and their use. The compositions are suitable for preventing and treating infections in plants and animals, including humans.

An encapsulated perfume composition comprising at least one perfume-containing aminoplast core-shell microcapsule dispersed in an aqueous suspending medium, the microcapsule being characterized in that it bears a positive charge.

Described herein is a new process for the preparation of powdered microcapsules encapsulating active volatile active ingredients, in particular a perfume or a flavour, the process being performed at room temperature. Powdered microcapsules obtainable by the process are also described. Perfuming and flavouring compositions as well as consumer products including the capsules are also described.

Microcapsules and techniques for the formation of microcapsules are generally described. In some embodiments, the microcapsules are formed in an emulsion (e.g., a multiple emulsion). In some embodiments, the microcapsule may be suspended in a carrying fluid containing the microcapsule that, in turn, contain the smaller droplets. In some embodiments, the microcapsules comprise a shell and a droplet at least partially contained within the shell (e.g., encapsulated within the shell), and may be suspended in a carrier fluid. In certain embodiments, the shell is a hydrogel comprising a poly(acid). In some cases, the poly(acid) is a polyanion. In some cases, the shell does not comprise a poly(base) or polycation (e.g., a polycationic poly electrolyte). In some embodiments, the microcapsules comprise a shell comprising a poly(acid) and a poly(anhydride).

The invention relates to stable dispersion of negatively-charged aminoplast microcapsules in non-suspending detergent compositions containing an anionic surfactant. The microcapsules are stably dispersed by means of a cationic polyampholyte, which is embedded in the shells of said microcapsules.

An object of the invention is to provide a method for producing a capsule or microbead having high encapsulation efficiency of an encapsulated substance, high production efficiency, and high versatility. The invention relates to a method for producing a microcapsule or microbead, comprising: a step of disposing a monomer droplet or polymer droplet containing a substance to be encapsulated, which has a surface coated with a plurality of solid fine particles, on a flat surface; and a step of solidifying the monomer droplet or polymer droplet disposed on the flat surface in a gas phase so as to form an outer shell of a capsule or microbead, thereby forming a region enclosed by the outer shell, wherein the substance is encapsulated in the region.
