Problems solved by technology

[0004] Although both lipoic acid and vitamin E have good antioxidant properties, their water solubility is poor, resulting in low bioavailability of both
In addition, because lipoic acid and vitamin E have strong antioxidant capacity, they are easily oxidized by oxygen in the air when exposed to the air, and lipoic acid will have a pungent smell after oxidation, so this has also become a bottleneck in application

Abstract

The invention relates to a water-dispersible oil-in-oil lipid nanocapsule containing lipoic acid and vitamin E oil and a preparation method of the water-dispersible oil-in-oil lipid nanocapsule. The preparation method includes: sequentially evenly mixing, by weight percentage, 0.1-5% of the lipoic acid, 0.1-20% of vitamin E oil, 1-10% of phospholipid, 2-20% of dipropylene glycol, 50-80% of glycerin and the like at 40-80 DEG C, and performing high-pressure homogenizing treatment to obtain the transparent or semitransparent water-dispersible oil-in-oil lipid nanocapsule containing the lipoic acid and the vitamin E oil, wherein the particle size of the water-dispersible oil-in-oil lipid nanocapsule is 250 nanometers. The water-dispersible oil-in-oil lipid nanocapsule is simple to prepare, good in water dispersity, good in bioavailability, good in repeatability, and the like.

Description

technical field [0001] The invention relates to a method for preparing water-dispersible oil-in-oil lipid nanocapsules containing lipoic acid and vitamin E oil, and belongs to the technical field of cosmetics. Background technique [0002] Lipoic acid is a coenzyme that exists in the mitochondria, similar to vitamins. After being absorbed by the human body, it can be quickly converted into dihydrolipoic acid in the cell, and then excreted from the cell membrane to participate in the extracellular metabolic cycle. Lipoic acid and dihydrolipoic acid can scavenge almost all oxygen free radicals in the body. Lipoic acid is widely used in cosmetics and pharmaceutical and healthcare industries due to its strong oxidizing ability. In the medical and health care industry, lipoic acid is mainly used to treat diabetes and its complications, acute coronary syndrome, protect ischemia-reperfusion injury, strengthen liver function, and improve dementia. In the field of cosmetics, people...
