PROBLEM TO BE SOLVED: To eliminate or minimize one or more of drawbacks of encapsulated benefit agents, namely, formulation limits, permeability, releasability and depositability, and provide additional perfume delivery opportunities.SOLUTION: Microcapsules are obtained through either oil in water (O/W) or water in oil (W/O) emulsification. The microcapsules are obtained by steps including dispersing an oil soluble amine modified polyfunctional polyvinyl monomer (or oligomer) and an oil soluble bi- or polyfunctional vinyl monomer or oligomer along with a free radical initiator, such as an azo or peroxy initiator, and an organic acid into an internal phase oil which is a non-solvent for a water phase.COPYRIGHT: (C)2016,JPO&INPIT【課題】カセル化有益剤の欠点である、配合制限、透過性、放出性および沈着性の1つ以上を排除又は最小化し、更なる香料送達機会を提供する。【解決手段】マイクロカプセルは、水中油(O/W)乳化又は油中水(W/O)乳化のいずれかにより得られる。アゾ又はペルオキシ開始剤等のフリーラジカル開始剤及び有機酸とともに、油溶性アミン変性多官能性ポリビニルモノマー(又はオリゴマー)及び油溶性二官能性若しくは多官能性ビニルモノマー又はオリゴマーを、水相では非溶媒である内相油に分散させる工程を含む工程によって得られる。【選択図】なし
