preparation example Construction

[0091] The present invention also provides a preparation method for co-transporting nanocomposites of phenylethylresorcinol described in the above technical solution, comprising the following steps:

[0092] A. Dissolving phenylethyl resorcinol, other water-insoluble whitening active ingredients, emulsifiers, and co-emulsifiers with complex lipids to obtain an oil phase;

[0093] B. Dissolving other water-soluble whitening active ingredients and polyols in water to obtain an aqueous phase;

[0094] 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;

[0095] D, the micron-scale dispersion obtained in step C is subjected to nano-processing to obtain a nano-scale dispersion, which is a co-transport nanocomposite of phenylethyl resorcinol;

[0096] There is no sequence between the steps A and B.

[0097] According to the water solubility of other whitening active ingredients, the presen...

Abstract

The invention relates to the field of cosmetics and provides a co-conveying nano composition of phenylethyl resorcinol. The co-conveying nano composition comprises phenylethyl resorcinol, other skin whitening active components, a nano medicine carrier as well as solvent complex lipid and water, wherein the phenylethyl resorcinol accounts for 0.1-10% of the total mass of the co-conveying nano composition; the other skin whitening active components comprise at least one of an antioxidant, a cutin peeling type active substance, a melanosome transferring inhibition active substance, an anti-glycation active substance and an anti-allergic agent; the nano medicine carrier comprises raw materials of an emulsifier, a Anti-allergic agent and polyhydric alcohols. Due to compounding of different skinwhitening components and carrying of the nano medicine carrier, a remarkable synergetic effect can be achieved, irritation of high-concentration phenylethyl resorcinol can be remarkably reduced, andthe co-conveying nano composition is good in stability, excellent in skin whitening effect, good in water solubility, good in skin permeability and widely applicable to cosmetics.

Description

technical field [0001] The invention relates to the field of cosmetics, in particular to a co-delivery nano composition of phenylethyl resorcinol 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 fo...
