Described herein are plant-based coacervate core-shell microcapsules, where the shell includes a plant protein extract, as well as methods and uses of the same.

Coacervate core-shell microcapsules

Described herein is a composite microcapsule slurry including at least one microcapsule having an oil-based core including a hydrophobic material, preferably a perfume, and a composite shell including a first material and a second material. The first material and the second material are different, the first material is a coacervate, the second material is a polymeric material, and the weight ratio in the slurry between the first material and the second material is between 50:50 and 99.9:0.1.

Composite microcapsules

The present invention relates to plant-based coacervate core-shell microcapsules, wherein the shell comprises a plant protein extract, as well as methods and uses of the same.

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.

Process for drying a suspension of hydrogel microcapsules

A flavor composition of a mixture of a) a first powder that includes a liquid flavor having a log P of up to about 3.5 loaded onto a first solid matrix material; and b) a second powder that includes a solvent loaded onto a second solid matrix material. The second solid matrix material is different than first solid matrix material and the flavor composition is in the form of a free-flowing powder. Also, methods of making a plated flavor powder and food compositions that include the powder.

Plated flavor powders

The invention relates to a process for preparing a hybrid coacervate capsule by mixing a first polymer with particles to form particle/polymer complexes; interacting a second polymer with the particle/polymer complexes to form a mixture comprising hybrid complex coacervates which contain particulate inclusions; and adding a core material to the mixture so that the hybrid complex coacervates deposit as a coating layer around the core material. The capsules form another embodiment of the invention.

Hybrid coacervate capsules

The invention relates to a method of making multilayer core/shell microcapsules for delivery of active agents such as fragrance components of perfume oils. The method includes forming an outer shell by coacervation surrounding an internal phase which contains the active agent; and forming an inner shell by interfacial polymerization at the interface between the internal phase and the outer shell. The internal phase contains the active agent. The microcapsules are typically incorporated in a consumer product wherein the multilayer shell prevents the active agent from release until desired, generally during use of the consumer product.

Multilayered core/shell microcapsules

The present invention relates to organic-inorganic hybrid core-shell microcapsules encapsulating an active ingredient such as a perfume and having a shell made from the hydrolysis and condensation reaction of particular polyalkoxysilane macro-monomeric compositions.
