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 floret essence, in particular to a preparation method of jasmine floret essence capsule. Background technique [0002] At present, jasmine floret essence is widely used in skin care products, perfume, shower gel, toothpaste, soap, cotton textiles and other daily chemical products. However, different components in Jasmine floret essence, such as alcohols, ethers, phenols, esters, etc., have different boiling points, and the volatility of components varies greatly, and some components still have strong volatility even at room temperature. The volatilization loss of volatile components will lead to the change of fragrance type. In addition, the sensitivity of many ingredients in essence to light, heat and oxygen will also affect its characteristic aroma. Therefore, improving the stability of essence and the persistence of fragrance is a problem that needs to be solved urgently in the fragrance ind...
