Abstract

The invention discloses a micro-capsule essence with two-layer capsule walls and a preparation method and an application thereof. The essence comprises inner oil essence, a first micro-capsule wall inthe middle and an outer capsule wall located on outermost layer. The micro-capsule essence with two-layer capsule wall of the invention has two-layer capsule wall structure , good mechanical strengthand flexibitity; in addition, when used in cloth the micro-capsule essence has the advantage of strong washing resistance, long fragrance holding time and easy storage. The preparation method of themicro-capsule essence with two-layer capsule walls adopts complex coacervation phase separation method to prepare the essence, the technological design is seasonable, the maneuverability is strong, micro-capsule essence with different fragrances can be designed according to different demands; in the preparation process, the mechanical strength of the micro-capsule essence can be effectively controlled so as to control the duration time and degree of the frangrance of the micro-capsule essence; in addition, the finished product of the micro-capsule essence with two-layer capsule walls preparedin the invention has high qualification rate and the micro-capsule essence with two-layer capsule can realize industrialized production.
