Embodiment 4

[0037] Example 4 Preparation of nanometer jasmine essence

[0038] After adding 0.66 parts by weight of the jasmine jasmine essence prepared in Example 3 and 2 parts by weight of polyoxyethylene (20) sorbitan monolaurate magnetically stirred evenly, add 96.02 parts by weight of Deionized water, magnetic stirring at 25°C until a homogeneous and stable jasmine essence emulsion is obtained. The pH of the resulting emulsion was adjusted to 2 with 1 mol / L hydrochloric acid solution. Then, 1.32 parts by weight of n-butyl cyanoacrylate was slowly added dropwise to the system at a rate of 3 drops / min under the condition of magnetic stirring at 25°C, and the polymerization was carried out under the condition of magnetic stirring at 25°C for 5 h. Then adjust the pH value of the system to 4 with 1 mol / L sodium hydroxide solution and continue the reaction for 1 h under the condition of magnetic stirring at 25 °C. Finally, adjust the pH value to 7 with 0.1 mol / L sodium hydroxide solution ...

Abstract

The invention discloses a preparation method of a jasmine sambac essence capsule. The nanometer essence consists of the following components by weight part: 0.66 to 1.06 jasmine sambac essences, 0.54 to 2.4 NBCA, 2 to 3.2 surfactants (selected from polyoxyethylene (20) sorbitan mono-laurate, polyoxyethylene sorbitan palmitate and polyoxyethylene sorbitan monooleate), and 93.62 to 96.26 deionized water. The nanometer jasmine sambac essence emulsion prepared by the invention is milk white, blue light phenomenon is obvious, and the system is uniform and stable. Jasmine flowers have obvious perfume and graceful and delicate fragrance. Tested by dynamic laser light scattering, the nanometer jasmine sambac essence has uniform particle size distribution, the average particle size is 70.8nm and the particle size distribution coefficient is 0.210.

Description

technical field [0001] The invention relates to a preparation method of jasmine essence, more particularly to a preparation method of jasmine essence capsule. Background technique [0002] At present, jasmine essence is widely used in skin care products, perfumes, shower gels, toothpaste, soaps, cotton textiles and other daily chemical products. However, different components in Jasmine jasmine essence, such as alcohols, ethers, phenols, esters, etc., have different boiling points, and the volatility of the components varies greatly, and some components are still highly volatile even at room temperature. The volatilization loss of volatile components can lead to changes in the flavor profile. In addition, the sensitivity of many components in essence to light, heat and oxygen will also affect its characteristic aroma. Therefore, improving the stability of the fragrance and the persistence of the fragrance is an urgent problem to be solved in the current fragrance industry. ...
