Abstract

The invention relates to an alcohol-free perfume based on a microfluidic technology and a preparation method thereof, and belongs to the technical field of cosmetics. According to the invention, O/W type liquid drops containing sodium alginate are prepared by utilizing a two-phase flow liquid drop generation technology in a microfluidic chip, and perfume microbeads are prepared by utilizing a cross-linking solidification technology of sodium alginate and calcium chloride. According to the invention, the sodium starch octenyl succinate, mannoprotein, jojoba gum and acacia are added into the perfume micro-beads, so that the embedding rate of the perfume micro-beads to plant essential oil and the slow release effect to aroma molecules are synergistically improved, and the storage stability of the perfume micro-beads is improved. As the raw materials and the preparation process of the perfume micro-beads do not involve alcohol components, the perfume micro-beads are safe and non-irritating, and therefore, the perfume micro-beads have important application value in preparing the alcohol-free perfume with high stability and long-acting slow release.

Description

Alcohol-free perfume based on microfluidic technology and preparation method thereof Technical Field The invention relates to the technical field of cosmetics, in particular to alcohol-free perfume based on a microfluidic technology and a preparation method thereof. Background The traditional perfume usually uses high-concentration alcohol as a solvent and a volatile booster, but is easy to cause skin irritation, dryness and anaphylactic reaction, and is not suitable for consumers such as alcohol sensitive people, infants and the like. Meanwhile, alcohol perfume belongs to inflammable liquid because of inflammable alcohol, so that the alcohol perfume is classified as a '3 rd dangerous article' in the using and transporting processes, and has high transportation and storage safety risks and high cost. In addition, the perfume containing alcohol volatilizes relatively quickly, the fragrance is kept relatively short, the original fragrance can be influenced by the alcohol, and the user can be provided with bad experience due to the fact that the alcohol smell is generated too much. At present, alcohol-free perfumes have become an important subdivision of the fragrance market. However, the existing alcohol-free perfume also has the problems of insufficient fragrance retention durability, easy layering, precipitation or turbidity of products during storage and the like. Therefore, the alcohol-free perfume product which is stable and high and has lasting fragrance has important application value. Disclosure of Invention The invention aims to overcome the defects of the prior art and provide alcohol-free perfume based on a microfluidic technology and a preparation method thereof. In order to achieve the above purpose, the technical scheme adopted by the invention is as follows: In a first aspect, the present invention provides a method for preparing perfume microbeads, comprising the steps of: S1, respectively weighing bergamot essential oil, orange flower essential oil, jasmine essential oil, mugwort essential oil, rose essential oil and patchouli essential oil, and uniformly mixing to obtain a dispersed phase, wherein the mass ratio of the bergamot essential oil, the orange flower essential oil, the jasmine essential oil, the mugwort essential oil, the rose essential oil and the patchouli essential oil is (3-2): 1-3): 0.5-1.5; S2, respectively weighing sodium starch octenyl succinate, mannoprotein, glycerol, nux-bang gum, acacia, sodium alginate and deionized water, and uniformly mixing to prepare a continuous phase, wherein the mass ratio of the sodium starch octenyl succinate, the mannoprotein, the glycerol, the nux-bang gum, the acacia, the sodium alginate and the deionized water is (2-4): 0.5-1): 0.1-2): 0.5-1): 0.5-1.5: 100; s3, shearing and emulsifying the disperse phase prepared in the step S1 and the continuous phase prepared in the step S2 through a microfluidic chip to form O/W type liquid drops; S4, introducing the O/W type liquid drops obtained in the step S3 into a calcium chloride collecting liquid to carry out a crosslinking reaction to form solidified particles, washing and drying the solidified particles to obtain the perfume micro-beads.
