Process for Preparing Microcapsules Having a Polyurea Shell and a Lipophilic Core Material
The application describes a process for the preparation of microcapsules, wherein the microcapsules have a volume average diameter d of 15 to 90 μηη and a percentage of the shell weight of 3 to 40%, with reference to the total weight of capsules, wherein the shell of the microcapsules comprises at least one polyurea and the core comprises at least one lipophilic component, comprising the step of adding hydroxyalkylcellulose to a dispersion of polyurea microcapsules, microcapsules and their uses.
ENCAPSULATED COMPOSITION COMPRISING CORE-SHELL MICROCAPSULES AND PROCESS FOR ITS PREPARATION
The present invention relates to a process for obtaining an encapsulated composition, to encapsulated compositions obtainable by this process, to products comprising these encapsulated compositions and to the use of these encapsulated compositions to provide consumer products.
Microencapsulation
An improved process of making a benefit agent delivery particle and an improved microcapsule made by such process are disclosed. The process comprises the steps of providing a first composition of water phase 1, water phase 2, water phase 3 and an oil phase, where a water phase multifunctional (meth)acrylate monomer is selected to have a hydrophilicity index of least 25, or even at least 30 and the oil phase multifunctional (meth)acrylate monomer has a hydrophilicity index of 25 or less, or even 20 or less. The water phases comprise water, initiator, a water-soluble or dispersible amine(meth)acrylate or hydroxyl(meth)acrylate, a multifunctional (meth)acrylate and one water phase comprises water, carboxyalkyl(meth)acrylate and a base or quaternary ammonium acrylate. Water phases are combined to prereact the hydroxy- or amine(meth)acrylate and the multifunctional (meth)acrylate to form a multifunctional hydroxyl-amine(meth)acrylate pre-polymer. The pre-polymer is combined with the remaining water phase and an emulsion is formed by emulsifying under high shear agitation, an oil phase comprising a multifunctional (meth)acrylate monomer and a benefit agent core material thereby forming a wall surrounding the benefit agent core material.
