Abstract

The invention provides a pterostilbene submicron lipid particle and a preparation method thereof, and belongs to the technical field of a carrier system in cosmetic preparation technology. The pterostilbene submicron lipid particle consists of pterostilbene, lipid, an emulsifier, a co-emulsifier, a stabilizer and water. According to the invention, the color change situation of the pterostilbene caused by long-time illumination is solved. The pterostilbene submicron lipid particle prepared by the invention can be well dispersed in the water, with high stability, and the pterostilbene submicron lipid particle, after dispersed in hot water, is fully transparent while the lipid particle is not separated out at low temperature; and the pterostilbene submicron lipid particle can be optionally matched with any cosmetic formulas.

Description

technical field [0001] The invention relates to the technical field of carrier systems in cosmetic preparation technology, and more specifically relates to pterostilbene submicron lipid particles and a preparation method thereof. Background technique [0002] Pterostilbene is a chemical component contained in Pterostilbene, but scientists have also discovered the existence of Pterostilbene in other plants, but because it was first discovered in Pterostilbene species, it is named Pterostilbene. Pterostilbene is a white or off-white powder crystal, which has rich medicinal value. It belongs to the antifungal active ingredient in dried blood products. It has certain effects on the treatment of cancer, hypertension, and hyperlipidemia. Recently, researchers have mastered the industrial synthesis method of pterostilbene. [0003] Pterostilbene is widely found in many natural plants such as grapes, blueberries, and dracaena. It has anti-oxidant and anti-inflammatory effects, and ...
