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

The present invention relates to a new process for the preparation of powdered microcapsules encapsulating active volatile active ingredients, in particular a perfume or a flavour, said process being performed at room temperature. Powdered microcapsules obtainable by said process are also an object of the invention. Perfuming and flavouring compositions as well as consumer products comprising said capsules are also part of the invention.

Process for drying a suspension at room temperature

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