Method for producing microcapsule without melamine formaldehyde

摘要

Problem: there is no melamine formaldehyde, and at the same time, for example, in the surfactant based consumer product, it functions more olfactory than the polyurea based capsule Providing an alternative capsule to the prior art known capsules that are stable as well as current melamine formaldehyde and / or polyurea based capsulesFlavored oil or flavor oilBy mixing at least one polyisocyanate having at least three isocyanate functional groupsForming an oil phase2) dissolved ionic surfactant or ionic colloidal stabilizer in waterForming the aqueous phase3) oil phase was added to the aqueous phase.Forming an oil dispersion system in water4) hardening process was carried out.Including forming a microcapsule slurryMethod for producing microcapsule without melamine formaldehydeNo selection
