preparation example Construction

[0090] The present invention also provides a method for preparing the α-arbutin co-delivery nano composition described in the above technical solution, comprising the following steps:

[0091] A. Dissolving α-arbutin, other water-insoluble whitening active ingredients, emulsifiers, and co-emulsifiers in oil to obtain an oil phase;

[0092] B. Dissolving other water-soluble whitening active ingredients with water to obtain an aqueous phase;

[0093] C. Mix and emulsify the oil phase obtained in step A with the water phase obtained in step B, and micronize to obtain a micron-scale dispersion;

[0094] D, the micron-scale dispersion obtained in step C is subjected to nano-processing to obtain a nano-scale dispersion, which is a co-delivery nano composition of α-arbutin;

[0095] There is no sequence between the steps A and B.

[0096] According to the water solubility of other whitening active ingredients, the present invention is divided into water-soluble other whitening acti...

Abstract

The present invention relates to the field of cosmetics, and provides a co-delivery nanocomposition of α-arbutin, including α-arbutin, other whitening active ingredients and nano drug-carrying carriers; the α-arbutin accounts for the co-delivery 0.05-20.0% of the total mass of the nano composition; the other whitening active ingredients include tyrosinase inhibitors, melanosome migration inhibitors, antioxidants, anti-glycation active substances and At least one of the anti-inflammatory agent; the raw material of the nano-loaded drug carrier includes emulsifier and co-emulsifier; also includes oil and water. The present invention achieves a significant synergistic effect through the compounding of different whitening mechanisms and the loading of nano drug-loaded carriers, and significantly reduces the skin melanin content through multi-target effects, and the co-delivery nanocomposition can realize the sustained release of drugs And controlled release, large drug loading, good stability, good water solubility and skin permeability, excellent whitening effect, and can be widely used in cosmetics.

Description

technical field [0001] The invention relates to the field of cosmetics, in particular to an α-arbutin co-delivery nanocomposition and its preparation method and application. Background technique [0002] Healthy and fair skin is the focus of most women's attention. Oriental women have always advocated the whitening effect of "skin like snow, condensed like fat". However, the current whitening skin care products on the market generally have the following problems: [0003] 1. Single whitening mechanism: most products only target one melanin formation and transfer mechanism, and cannot achieve full-effect whitening; [0004] 2. Poor product stability: When making most whitening products on the market, whitening ingredients are directly added to the formula, which can easily lead to discoloration and odor change of the product, and even layering and thickening of the paste; [0005] 3. Low whitening efficiency: Due to the skin's own barrier, it is difficult for whitening acti...
