The microcapsule essence is an essence microcapsule which can achieve the effect of controlling release and comprises a core material, a slow release layer and a quick release layer, wherein the slow release layer and the quick release layer sequentially wrap the core material.

The microcapsule essence is a double-wall type microcapsule essence, and has a structure that the capsule core is coated with an inner wall layer and a quick release layer, and the fragrance of the quick release layer is similar to that of the capsule core by using fragrant substances; which dissolves when immersed in water for a long time. The quick release layer is dispersed in the dose, and when the aerosol actuator is pressed, the quick release layer is directly sprayed in the air along with the dose, and the fragrance is rapidly burst.

Furthermore, the inner wall layer of the microcapsule essence is hydrophobic and insoluble in water, and can be stably stored in a water-based formula for a long time when the quick release layer is ablated in water.

Furthermore, the particle size of the microcapsule essence is micron grade, so that the microcapsule essence is easy to disperse in the dosage and is not easy to separate.

The dispersing agent is formed by combining sodium naphthalenesulfonate formaldehyde condensate and sodium dodecyl sulfate according to a ratio of 4: 1.

The fill dose is filtered into a sealed binary packed empty can by high pressure. Water bath leakage detection: soaking in 50 deg.C water bath, sealing with the edge of the aerosol can, keeping air bubbles from emerging, detecting leakage in water bath for 5min, adding touch actuator, large cover, etc., and detecting.

The slow-release air freshener has the following advantages:

1. the selected essence microcapsules endow the product with the core advantages of long aroma duration and good aroma outbreak;

2. the production process is simple, and the raw materials are environment-friendly and easy to degrade;

3. the pressure is stable, and the use effect is stable.
