Abstract

The invention belongs to the field of daily cosmetics, and discloses preparation of a plant essential oil microcapsule and application of the plant essential oil microcapsule in a hair product with long-acting moistening and long-lasting fragrance. The plant essential oil microcapsule is prepared by taking plant essential oil as a core material and cyclodextrin and chitosan as wall materials through spray drying, the average particle size range of the plant essential oil microcapsule is 0.4-400 microns; after the plant essential oil microcapsule is added into a hair product, consumers can adsorb and stay part of microcapsule particles containing the plant essential oil on washed hair and scalp; the microcapsule particles break in the process of combing hair and rubbing the hair to releaseplant essential oil, so that the effects of moistening scalp and hair for a long time and keeping fragrance for a long time are achieved.

Description

technical field [0001] The invention belongs to the field of daily cosmetics, in particular to the preparation of a plant essential oil microcapsule and its application in long-acting moisturizing and lasting fragrance hair products.
