Detailed Description
The technical solutions of the present invention will be described clearly and completely with reference to the following embodiments, and it should be understood that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
According to one aspect of the invention, the hawthorn beauty skin cream is mainly prepared by adding an extract of hawthorn fruits coated by liposome into a cream matrix.
In the invention, the hawthorn fruit extract is rich in various substances such as procyanidine, plant organic acid, tannin and the like, wherein:
procyanidine in fructus crataegi extract has multiple phenolic hydroxyl groups, has super strong reducibility, and can exert strong free radical scavenging effect after entering skin tissue and blood vessel, thereby protecting new skin cell and mature cell, and improving human facial cell state to a certain extent. In addition, according to research, it is found that acne and alopecia are closely related to a biological enzyme generated by excessive secretion of male hormones in human beings, which is usually present in the root of hair follicle, and causes the pores to be excessively opened to cause external bacterial invasion to form folliculitis, and normal passage to be closed, and finally causes the generation of pox and the failure of normal growth (which grows out but dies soon). Epicatechin dimer in fructus crataegi procyanidine has the effects of inhibiting and weakening the expression of biological enzyme, and can be used for treating acne and alopecia;
the tannin in the hawthorn fruit extract can generate good convergence on skin, and can resist the invasion of external environment microorganisms by tightening the skin and shrinking pores;
the organic acids such as fruit acid, citric acid and the like contained in the hawthorn fruit extract have small molecular weight, can permeate into the root of hair follicle, inhibit and kill anaerobic bacteria, and also can play a certain role in treating folliculitis;
meanwhile, the procyanidine in the hawthorn fruit extract has a plurality of phenolic hydroxyl groups in the molecular structure and large polarity, so that the hawthorn fruit extract has strong hydrophilicity, and epicatechin oligomers and polymers are stored in the hawthorn fruit extract, so that the molecular weight difference is large, the oligomers are easily oxidized and are particularly oxidized in an aqueous medium to lose effectiveness. Therefore, the skin care product is prepared after the skin care product is coated with the stable liposome-coated hawthorn fruit extract.
Therefore, the hawthorn beauty skin cream is mainly prepared by adding the hawthorn fruit extract coated by the liposome into a cream matrix. The hawthorn fruit extract is rich in various substances such as procyanidine, plant organic acid, tannin and the like, has the effects of resisting skin aging, removing acne, whitening, brightening and the like, and can achieve the effects of clearing free radicals of human skin, whitening and firming skin and reducing pores. However, procyanidins have strong hydrophilicity, and epicatechin oligomers in procyanidins are easily oxidized in water and thus are ineffective. Therefore, the skin care product must be prepared after being wrapped into a stable lipid coating.
In a preferred embodiment of the present invention, the content of procyanidins in the hawthorn fruit extract is 90 to 95wt%, and the content of total organic acids in the plant is 1 to 1.5 wt%.
As a preferred embodiment, the content of procyanidine in the hawthorn fruit extract is 90-95 wt%, so that the prepared skin cream has stronger anti-free radical activity; the content of the plant organic total acid is 1-1.5 wt%, and the better effect of inhibiting and killing anaerobic bacteria can be achieved.
According to the invention, researches show that when the content of procyanidine in the hawthorn extract is lower than 90%, the content of organic acid is higher, the pH value is less than or equal to 4, the polarity is very high, and the lipid is extremely difficult to wrap the extract, even cannot wrap the extract. With the increase of the content, the wrapping rate gradually increases. When the content is higher than 95%, the pH value of the extract is more than or equal to 6, and if the purity of the procyanidin is continuously improved, the acidic environment created by the organic acid is gradually lost, so that the procyanidin is rapidly denatured and ineffective, the organic acid can inhibit and kill bacteria, epidermal cells aged by skin are removed, and the effect of cleaning the skin is poor.
In a preferred embodiment of the invention, the liposomes are submicron liposomes.
In a preferred embodiment, the liposome is a submicron liposome, and the stability of the procyanidine in the beauty skin cream can be greatly improved after the submicron liposome is used for stably wrapping the hawthorn fruit extract.
In a preferred embodiment of the present invention, the skin cream further comprises salicylic acid.
Preferably, the salicylic acid accounts for 1-3% of the total mass of the hawthorn beauty skin cream.
As a preferable embodiment, the salicylic acid has weak corrosivity to skin, accounts for 1-3% of the total mass of the hawthorn beauty skin cream, and can effectively remove aged and apoptotic epidermal cells.
In a preferred embodiment of the present invention, the cream base is an O/W type emulsion comprising an oil phase base and an aqueous phase base, wherein:
the oil phase matrix mainly comprises, by weight, 20-30 parts of white vaseline, 8-12 parts of octadecanol, 2-6 parts of glyceryl monostearate, 1-5 parts of sodium dodecyl sulfate, 4-8 parts of shea butter and 202-6 parts of ceteareth-202;
the water-phase matrix mainly comprises 12-16 parts by weight of glycerin, 0.2-1 part by weight of ethyl p-hydroxybenzoate and 180-22 parts by weight of distilled water.
In a preferred embodiment, the cream base is an O/W emulsion, which is more easily absorbed by human skin.
In the above preferred embodiment, the oil phase base further comprises a perfume.
Preferably, the essence is rose essential oil.
As a preferred embodiment, essence is added into the oil phase matrix to mask the unpleasant taste of the extract.
According to one aspect of the invention, the preparation method of the hawthorn beauty skin cream comprises the following steps:
(a) preparing a cream base: respectively mixing an oil phase matrix and a water phase matrix uniformly, heating to 70-80 ℃, preserving heat for 15-25 minutes, and then slowly adding the oil phase matrix into the water phase matrix, wherein the mass ratio of the oil phase matrix to the water phase matrix is 1: 3-5, stirring while adding to form a cream matrix;
(b) and (3) liposome coating: grinding the hawthorn fruit extract, sieving the ground hawthorn fruit extract by a sieve of 100-150 meshes, and then coating the hawthorn fruit extract by using liposome to prepare the hawthorn fruit extract coated by the liposome;
(c) uniformly mixing and preparing: and (c) adding salicylic acid and the hawthorn fruit extract coated by the liposome prepared in the step (b) into the cream matrix prepared in the step (a), and fully and uniformly stirring to prepare the hawthorn beauty skin cream.

In a preferred embodiment of the present invention, the coating rate of the haw apple extract in step (b) with liposome is 3-5%.
As a preferred embodiment, it has been found that procyanidins extracted from other plants such as grape seeds have a high epicatechin multimer (5 polymers or more) content, i.e., a high average degree of polymerization and a high molecular weight, and thus it is difficult for liposomes to encapsulate them, and the encapsulation rate is low, usually 2% or less, and the cream procyanidins obtained do not reach a certain effective amount and hardly exert their effects. The epicatechin oligomer (less than 4 polymers) in the procyanidine extracted from the hawthorn has high content, small molecular weight and small volume, and can effectively improve the coating rate of the liposome to 3-5%.
In a preferred embodiment of the present invention, the content of the liposome-coated hawthorn fruit extract in the hawthorn cosmetic skin cream prepared in step (c) is 5 to 15 wt%.
As a preferred embodiment, the content of the liposome-coated hawthorn fruit extract in the hawthorn beauty skin cream is 5-15 wt%, so that the hawthorn beauty skin cream has better effects of resisting skin aging, removing acne, whitening, brightening and the like.
Preferably, the content of the hawthorn fruit extract coated by the liposome in the hawthorn beautifying skin cream is 10 wt%.
According to one aspect of the invention, the hawthorn beauty skin cream is used as day cream.
In the invention, because the free radical damage of human skin in daytime is greatly more than that in night, the beauty skin cream rich in procyanidine with super-strong anti-free radical activity is applied as day cream.
