Problems solved by technology

[0005] At present, there are endless moisturizing products on the market, but they often only consider hydrating and moisturizing, and cannot really lock and store water, and also ignore the repair of the horny barrier. Such products cannot improve the hydration ability of the skin and maintain normal skin Function; secondly, the exogenous lipids secreted by the stratum corneum of the skin and the endogenous lipids secreted by the sebaceous glands are both oily substances. Therefore, the fat-soluble substances are more absorbed by the skin than the water-soluble substances, and the water-soluble moisturizing active ingredients are penetrated through the skin. Poor translucency, low utilization rate, and due to the skin's own barrier function, it is difficult for active ingredients such as collagen to penetrate the stratum corneum and enter the dermis, greatly reducing the moisturizing effect

preparation example Construction

[0078] The present invention provides the preparation method of the bird's nest acid moisturizing and repairing nanocomposite described in the above technical scheme, comprising the following steps:

[0079] Mix part of bird's nest acid, tetrahydromethyl pyrimidine carboxylic acid, human collagen, polyol and part of water to obtain the inner water phase;

[0080]Mix liquid lipids, emulsifiers, and co-emulsifiers to obtain an oil phase;

[0081] mixing and emulsifying the internal water phase and the oil phase to obtain a water-in-oil internal system;

[0082] Mixing the remaining bird's nest acid and the remaining amount of water to obtain the outer water phase;

[0083] mixing and emulsifying the water-in-oil internal system and the external water phase to obtain a water-in-oil-in-water bicontinuous system;

[0084] Micronizing the water-in-oil-in-water bicontinuous system to obtain a micron-scale dispersion;

[0085] Nanoscale treatment is performed on the micron-scale di...

Embodiment 1

[0107] According to the mass percentage of the ingredients, 0.08% bird's nest acid, 20% tetrahydromethyl pyrimidine carboxylic acid, 2% human collagen, 6% polyethylene glycol-200 and 56% purified water are placed in a water bath at a temperature of 50°C. Stir and mix down to obtain the inner water phase;

[0108] Mix 3% Caprylic Capric Triglyceride, 4% PEG-9 Cocoyl Glycerides, 4% Polyglyceryl-10 Myristate, and 3% Butanol-3 in a water bath at a temperature of 50°C , to get the oil phase;

[0109] Add the internal water phase dropwise to the oil phase at a rate of 3 drops / second and stir continuously at 50°C and a rotation rate of 600r / min to obtain an internal water-in-oil system;

[0110] Add 0.02% bird's nest acid to 1.9% purified water, heat and dissolve in a water bath at 50°C to obtain the outer water phase;

[0111] (Specifically, stir and mix 0.08g of bird's nest acid, 20g of tetrahydromethylpyrimidinecarboxylic acid, 2g of human collagen, 6g of polyethylene glycol-200...

Embodiment 2

[0120] Stir and mix 0.8% bird's nest acid, 12% tetrahydromethylpyrimidinecarboxylic acid, 7% human collagen, 1% glycerin and 50% purified water in a water bath at a temperature of 50°C to obtain an inner water phase;

[0121] Mix 2% triglyceride (ethylhexanoate), 6% polyoxyethylene sorbitan fatty acid ester, and 10% glyceryl polyether-2 cocoate in a water bath at a temperature of 50°C to obtain an oil phase ;

[0122] Add the inner water phase dropwise to the oil phase at a rate of 4 drops / second and stir continuously at 50°C and a rotation rate of 400r / min to obtain an oil-in-water inner system;

[0123] Add 0.2% bird's nest acid to 11% purified water, heat and dissolve in a water bath at 50°C to obtain the outer water phase;

[0124] Add the water-in-oil internal system dropwise to the external water phase at a rate of 4 drops / second and stir continuously at 50°C and a rotation rate of 400r / min to obtain a water-in-oil-in-water bicontinuous system;

[0125] The water-in-oi...

Abstract

The invention relates to the technical field of cosmetics, in particular to a sialic acid moisturizing and repairing nano composition, a preparation method thereof and a cosmetic. The sialic acid moisturizing and repairing nano composition provided by the invention is prepared from the following components in percentage by mass: 0.1 to 20 percent of sialic acid, 0.1 to 20 percent of tetrahydromethylpyrimidine carboxylic acid, 0.1 to 10 percent of human collagen, 1 to 10 percent of liquid lipid, 1 to 20 percent of emulsifier, 1 to 20 percent of co-emulsifier, 1 to 20 percent of polyhydric alcohol and the balance of water. The sialic acid moisturizing and repairing nano composition provided by the invention not only has excellent moisturizing and hydrating effects, but also can firmly lock moisture stored in skin, repair cutin barrier, promote keratinocyte differentiation and skin renewal, and maintain normal functions of skin.

Description

technical field [0001] The invention relates to the technical field of cosmetics, in particular to a nano composition of bird's nest acid for moisturizing and repairing, a preparation method thereof, and a cosmetic. Background technique [0002] The skin is located on the surface of the human body and is the first line of defense of the human body, especially the stratum corneum, which has very important functions. The stratum corneum of the epidermis is a densely packed keratinocyte, and the keratinocyte itself resists environmental adverse factors such as dryness by regulating water flux and retention. The water content of the stratum corneum accounts for 15% to 35% of the epidermis. If the water content of the stratum corneum is less than 10%, it will cause the stratum corneum to dry, scale, fall off, dry and crack, and even cause a series of skin diseases. [0003] The moisture of the skin is mainly stored in the dermis. The main component of the outer matrix of the der...
