Abstract

A glabridin-cladded nano solid lipid carrier contains 0.02-8% of glabridin, 2-20% of a solid emulsifier, 2-15% of solid lipid, 1-15% of liquid lipid, 2-10% of polyols, 0.5-5% of phospholipid, 0.02-1% of inorganic salt, 0.01-0.8% of a preservative and deionized water. The invention further provides a preparation method of the glabridin-cladded nano solid lipid carrier. The stability of the glabridin is improved by the glabridin-cladded nano solid lipid carrier, the infiltration of the glabridin into the skin is promoted, and the skin whitening and anti-oxidation effects are improved.

Description

[0001] This application is based on the Chinese patent application number 201410713479.3, the applicant is Infinitus (China) Co., Ltd., and the name is "a nano-solid lipid carrier coated with glabridin and its preparation method and application" as a priority document. Apply. technical field [0002] The invention belongs to the technical field of carrier systems in cosmetic preparation technology, and in particular relates to a nanoscale carrier and a preparation method thereof, in particular to a nanometer solid lipid carrier coated with glabridin and a preparation method thereof. Background technique [0003] With the improvement of living standards, more people's demand for cosmetics has changed from a single care type to a functional type, such as whitening, freckle removal, and anti-acne. Fair skin has always been admired by oriental women, and the concept of whitening is gradually changing. In the 1970s, people relied on physical masking whitening agents such as "whi...
