Description

Essence composition for delaying skin aging and preparation method thereof

Technical Field

The invention belongs to the technical field of cosmetics, and particularly relates to an essence composition for delaying skin aging and a preparation method thereof.

Background

With the development of economy and the continuous improvement of living standard of people, the pursuit of the youth of faces is the expectation of the elder people, and the pursuit of women for life is continuous, and the pursuit of women for life is the career for fighting for life.

Facial aging is not a sudden, cumulative process in which the facial skin and structures are constantly changing by extrinsic and intrinsic effects, such as: thickening and aging of epidermis, reduction of water content of epidermis, generation of color spots, drooping of eyelids and cheeks, generation of raised lines, fishtail lines, and stature lines, etc. The manifestation of such facial aging is influenced by several major factors, in addition to the limitation of the life span of stem cells by individual genetic genes.

First, facial muscles are not distributed continuously, but are regionally distributed in a lump. The muscle groups include forehead, eye periphery, nasal wing, cheek, lip periphery, etc. We know that above the muscle is the fat layer, then the dermal collagen layer, the epidermal layer. In the infant period, the whole face is relatively uniform in the process of establishing facial motor muscles, and mainly consists of epidermis, dermis and subcutaneous fat. With age and facial expression, the connective muscles develop gradually. Since muscles are not continuous but massive, discontinuities in the facial contour occur with age. The aging characteristics of the face such as lower eye sagging, cheek bulging, cheek sagging and lip muscle dislocation, facial wrinkle generation and the like gradually appear along with the aging of the face, and the aging is remarkable in that the aging is represented by aging in a block type, and the face loses the smoothness and smoothness.

Second, the second important factor affecting the aging process of the face is ultraviolet rays. The american dermatologist Albert Kligman suggested that "photoaging is a chronic skin disorder" is a high generalization of photoaging. Ultraviolet rays, particularly UVA ultraviolet rays with the wavelength of 320-400nm, can reach the dermis, can activate melanocytes, promote skin blackening and color spot formation, damage Langerhans immune cells, reduce the immunity of the skin, damage fibroblasts, reduce the collagen generation capacity of endoplasmic reticulum of cells, cannot supplement new collagen, influence the fullness and elasticity of the dermis, and cause irreversible wrinkles after long-term development.

Thirdly, the third important influencing factor of the facial aging process is the reduction of the filling degree of the cuticle and the reduction of the water content. The moisture content of the infant cuticle is as high as 60%, and the moisture content of the infant cuticle is reduced to below 30% and even below 10% for adults. In the aging development process, the synthesis of lipid among epidermal cells is reduced, the expression of aquaporin-3 is reduced, the synthesis capacity of hyaluronic acid is reduced, the water content of stratum corneum is reduced, the skin lacks the filling degree, the related cell biological functions of the epidermis are also reduced, the appearance of the skin is rough and not fine, and the generation of fine wrinkles is further initiated.

However, the existing facial essence composition, such as a composition for promoting skin collagen production with publication number CN109260454A, is prepared by a method comprising two components, i.e. a component a and a component b; the component A is an oral preparation and comprises the following raw materials in parts by weight: vitamin C1-2 parts, collagen peptide 4-6 parts, traditional Chinese medicine extract 12-15 parts, sustained-release gel 1-2 parts, and deionized water 10-12 parts; the component B is an injection preparation and comprises calcium hydroxyapatite and physiological saline, and the mass ratio of the calcium hydroxyapatite to the physiological saline is 1: 8-12; the mass ratio of the first component to the second component is 10: 3-4. Said invention uses oral preparation to attain the goal of whitening, moistening skin and resisting senility, and utilizes subcutaneous injection to possess biological potential, attract fibroblast to enter and produce new collagen, and make them supplement each other to promote generation of skin collagen.

The main purpose of the invention is to generate collagen, but the component B needs to meet the requirement of hypodermic injection, so the cost is high, the operation difficulty is high, and an operator can hardly perform hypodermic injection operation by himself; if the subcutaneous injection is performed by self operation, bacteria can be easily infected, and even some accidents such as tetanus occur, so a new technical scheme needs to be proposed to solve the problems.

Disclosure of Invention

Aiming at the defects in the prior art, the invention aims to provide the essence composition for delaying skin aging, which is safe and convenient to operate, can delay skin aging, promote the generation of collagen, improve the fullness of skin, increase the moisture content of stratum corneum and has good anti-aging effect.

In order to achieve the purpose, the invention provides the following technical scheme: the essence composition for delaying skin aging comprises the following components in parts by weight:

the compound ceramide is selected from one or more of ceramide 3, ceramide 6II, ceramide 1 and ceramide 2.

Further, the compound ceramide comprises 0.005-0.05 part of ceramide 3, 0.0025-0.025 part of ceramide 6II, 0.000005-0.00005 part of ceramide 1 and 0.004-0.08 part of ceramide 2.

By adopting the technical scheme, the astaxanthin is one of carotenoids, belongs to a fat-soluble and water-soluble pigment, and is a strong natural antioxidant. The chemical name of the astaxanthin is 3, 3 '-dihydroxy-4, 4' -diketone-beta, and the chemical formula is as follows: c ₄₀ H ₅₂ O ₄ . The special molecular structure of astaxanthin can penetrate through the outer wall of human cells, directly remove oxygen free radicals in the cells, enhance the regeneration capacity of the cells, maintain the functional balance of the human body, reduce the accumulation of aged cells and protect the health of the cells and DNA from inside to outside. The strong antioxidant property of astaxanthin makes it a potential photo-protecting agent, effectively scavenging free radicals which cause skin aging, protecting cell membranes and mitochondrial membranes from oxidative damage, and preventing skin photo-aging. Therefore, astaxanthin has effects of preventing ultraviolet radiation, preventing skin photoaging, enhancing body metabolism, and improving immunityHas antiaging effect. The ginger root extract is concentrated solution with biological active components extracted from ginger, and has the functions of enhancing immunity, resisting bacteria, killing pests and diminishing inflammation.

Ceramide naturally exists in the intercellular substance of stratum corneum, plays a key role in the physiological function of stratum corneum, makes the skin smooth and delicate, and prevents the skin from drying due to water loss; meanwhile, ceramide is also involved in various physiological processes such as cell differentiation. The compounded ceramide is a composite product of various ceramides (such as ceramides 1-3), and the cetyl N-palmitoyl hydroxyproline is synthetic ceramide (namely ceramide-like), can overcome the defects of natural ceramide, and has a structure similar to that of the natural ceramide. The cetyl N-palmitoyl hydroxyproline has the effects of moisturizing and removing fine lines, and can effectively repair the skin and play a role in skin barrier when being matched with the compound ceramide.

Moisturizers are hydrophilic skin moisturizing substances that have the ability to bind water in the lower humidity range, moisturize the skin, and they can help maintain the skin in a more than normal equilibrium moisture content by controlling the exchange of moisture between the product and the surrounding air, and thus, reduce skin dryness.

Acetyl hexapeptide-8 is also called as ayurrin, is a neurotransmitter inhibitory peptide, and has high anti-wrinkle activity and small side effect. The anti-wrinkle mechanism is as follows: acetyl hexapeptide-8 is involved in competing for the site of SNAP-25 at the vacuolar complex, thereby affecting complex formation; when the vesicle complex is slightly unstable, the vesicle cannot effectively release neurotransmitters, thereby causing the reduction of muscle contraction and preventing the formation of wrinkles.

The hydrolyzed collagen is small molecular weight collagen (the molecular weight collagen is collagen with the molecular weight of less than 1500 daltons) which is subjected to hydrolysis treatment, is very easy to absorb, can fully meet the requirements of human bodies on repairing skin and connective tissues, and has the effects of inhibiting melanin, whitening skin, delaying aging, improving microcirculation, removing freckles and wrinkles, tightening skin, repairing fine wrinkles and the like.

The p-hydroxyacetophenone is prepared by acetic acid and phenyl vinegar through aluminum trichloride catalytic rearrangement, plays a role of an antioxidant in cosmetics, while the tocopherol is a product obtained after vitamin E hydrolysis and is one of the most main antioxidants, and the antioxidant effect of the tocopherol, the p-hydroxyacetophenone, the astaxanthin and the ginger root extract can be further improved through compound use.

The campesterol can be used as humectant with moisture keeping effect and anti-inflammatory effect.

In conclusion, the cholesterol, the caprylic/capric triglyceride, the hexyldecanol and the rape sterol are common emollients, not only can play a role in moisturizing, but also can form a structure similar to an oil film on human skin when the moisturizer is coated on the human skin, and the formed oil film is compounded with four kinds of ceramide to play a good role in skin barrier.

Further, the humectant is selected from one or more of ethylhexyl glycerin, butanediol, glycerin, sodium hyaluronate, 1, 2-pentanediol, 1, 2-hexanediol, and caprylyl glycol.

By adopting the technical scheme, the ethylhexyl glycerin, the butanediol, the glycerin, the sodium hyaluronate, the 1, 2-pentanediol, the 1, 2-hexanediol and the caprylyl glycol are common humectants, and various humectants can be matched with four ceramides and similar ceramides for use, so that the skin fullness is improved, and the moisture content of the horny layer is greatly increased.

Further, the preservative also comprises 0.02-0.2 part of a chelating agent, wherein the chelating agent is disodium EDTA.

By adopting the technical scheme, the EDTA disodium is a common chelating agent, and the EDTA disodium can play a role in chelating heavy metal ions, so that the phenomenon of skin heavy metal poisoning is effectively reduced.

Further, the inulin comprises 0.09-1.8 parts of inulin and 0.01-0.2 parts of brown algae extract.

Further, the main component of the brown algae extract is fucoidan.

By adopting the technical scheme, the inulin is reserve polysaccharide in plants and is water-soluble dietary fiber. Brown algae extract is a common bioactive substance (such as fucoidan sulfate) extracted from marine algae, and can help human cells to improve autophagy function and kill or consume dead cells. Wherein the fucoidan has immunomodulatory activity, and can be used for producing cytokine and chemokine by macrophage and splenocyte; meanwhile, the fucosan sulfate can also inhibit the production of active oxygen free radicals and promote the elimination of the active oxygen free radicals, and has obvious antioxidant activity. In conclusion, the prebiotics such as inulin and brown algae can form a biological film on the surface of skin, so that the skin micro-ecology can be effectively improved, and the skin is healthier.

Further, the thickening agent is selected from one or more of carbomer, xanthan gum, acrylic acid (ester)/C10-30 alkanol acrylate cross-linked polymer and polyacrylic acid.

By adopting the technical scheme, the carbomer is a pharmaceutic adjuvant and has no special side effect. The acrylic crosslinked resin obtained by crosslinking pentaerythritol and acrylic acid has important applications such as thickening and suspending. Xanthan gum is an extracellular microbial multi-pool produced by drunkenness of saccharides by xanthomonas. Due to the special structure and colloid characteristics of macromolecules, the product has multiple functions and can be used as an emulsifier, a stabilizer, a gel thickener and the like.

In addition, the acrylic acid (ester)/C10-30 alkanol acrylate cross-linked polymer is a film forming agent, can replace an emulsifier to be used in cosmetics, not only reduces the irritation effect of the emulsifier on skin, but also has good anti-irritation effect and good safety because the acrylic acid (ester)/C10-30 alkanol acrylate cross-linked polymer has larger molecular weight and can not be absorbed through skin. Polyacrylic acid is used as a binder, an emulsion stabilizer and a film forming agent in cosmetics.

Therefore, carbomer, xanthan gum, acrylic acid (ester)/C10-30 alkanol acrylate cross-linked polymer and polyacrylic acid are all the participating thickening agents, and can play a role in improving and increasing the viscosity of the essence composition.

Further, the skin conditioner is one or more selected from phytosphingosine, 4-tert-butylcyclohexanol, bisabolol, dipotassium glycyrrhizinate, beta-glucan, hydroxyphenylpropionamide benzoic acid, humic acid, and mineral salt.

Further, the beta-glucan can be oat beta-glucan-or highland barley beta-glucan.

By adopting the technical scheme, the phytosphingosine is a precursor of phospholipids (Ceramides), is relatively similar to skin lipids, and is an important component for water retention and barrier function. The phytosphingosine is one of important oil components in human epidermis, the phytosphingosine in the human skin is gradually reduced along with the increase of age and the aging period, so that dry skin and rough skin are caused, and the external phytosphingosine has the effects of efficiently keeping the skin soft and moist and protecting the cortex; the phytosphingosine has antibacterial and antiinflammatory effects, and can be used for preventing and treating skin diseases such as acne. While 4-tert-butylcyclohexanol is white needle-like or powdery crystal. It has patchouli-like fragrance of radix aucklandiae, and the active substance can effectively relieve sensitive skin, thereby inhibiting prickling and burning.

Furthermore, the beta-glucan may be oat beta-glucan-or highland barley beta-glucan. It can be used for keeping moisture, removing wrinkle, relieving inflammation, and promoting stratum corneum regeneration. The bisabolol is extracted from chrysanthemum plants, has the functions of resisting inflammation and inhibiting bacteria, has good stability and good compatibility with skin, reduces skin inflammation, relieves skin acne, prevents acne, improves the anti-irritation capability of the skin, repairs the skin with inflammation injury, and improves the SPF value in a sun-screening product. The bisabolol has obvious anti-inflammatory and antispasmodic effects, and on the function, the natural bisabolol has twice of the effects of a synthetic product, has the functions of relieving pain, alleviating irritation and resisting allergy, and has skin care effect on allergic skin or children skin. The bisabolol has high permeability on the skin cortex, and the action of the bisabolol is dozens of times of that of a common penetrant; can be used as main agent or adjuvant for preventing and treating skin diseases such as acne, and also has skin conditioning effect.

Therefore, the essence composition does not adopt common soothing agents, such as dipotassium glycyrrhizinate or hydroxyphenyl propionamide benzoic acid and the like, and meanwhile, the brown algae extract is extracted from natural plants, so that the raw materials are green and environment-friendly, and have no stimulation to skin and muscle of a human body. Meanwhile, the excellent activities of the brown algae extract and the fucoidan sulfate are combined, the production of active oxygen free radicals can be inhibited, the active oxygen free radicals can be cleared, the inflammation problems of skin allergy, redness and the like can be improved, and the skin can be repaired.

Humic acid is the main component of organic matter in natural water, and is mainly derived from low molecular weight components (for example, less than 1500 daltons) of soil humus and decomposition and lower plankton of aquatic plants, and the basic structure of the humic acid is aromatic ring and alicyclic ring, and the ring is connected with carboxyl, hydroxyl, carbonyl, quinonyl and methoxyl functional group. Due to the influence of various functional groups on the complexity of the molecular structure of the humic acid, the humic acid has a plurality of physical and chemical properties and has good colloid property, solubility, ion exchange property, adsorbability, precipitability, complexation, oxidation-reduction property and thermal stability. Because the water that uses in this application does not contain the halide, the humic acid that adds this moment can promote the good anti-oxidant of essence composition and accuse oily performance on the contrary. The mineral salt is a mineral component containing more than 70 trace elements, such as selenium element, magnesium element, zinc element, silicon element, calcium element, sodium element and the like, can supplement various trace element nutrients required by skin cells of the head, enhance the activity of the cells, improve the tolerance of the cells and improve the skin hydration, thereby being beneficial to prolonging the aging, providing prebiotics for skin microorganisms and maintaining the balance of skin biofilms.

Test subjects: the purification compositions obtained in examples 1 to 6 were used as test samples 1 to 6, and the purification compositions obtained in comparative examples 1 to 3 were used as control samples 1 to 3.

The test method comprises the following steps: randomly selected 45 persons of 18-40 years old in the same area, each group having 5 test samples. Firstly, facial cleanser (commercially available Nivea condensed water is used for collecting 150g of foam facial cleanser actively) is adopted, then the test samples 1-6 and the control samples 1-3 are respectively smeared on the skin after facial moisture is wiped off, after complete absorption, the moisture content of the stratum corneum of the skin at the position of nonuse, 0.5h, 1h, 2h, 3h and 4h is respectively tested by adopting a skin moisture content tester (Hengda technology), and real-time moisture loss data statistics is respectively carried out.

And (3) test results: as is clear from Table 2 and FIG. 1, the water content of the stratum corneum of each of the samples 1 to 6 was higher than that of the control sample 1. The stratum corneum water loss was greatest with test sample 4 within 1 hour, and the test sample 4 was relatively steep. Whereas the moisture content of the stratum corneum of the skin using test sample 4 decreased slowly over a period of 1-4 hours, the curve of test sample 4 was relatively flat.

As is apparent from fig. 1, the water content curves of control sample 1 and control sample 2 are significantly lower than those of test sample 4 and control sample 3. The curves for test sample 4 and control sample 3 show that: the water content of control sample 3 was higher than that of test sample 4 before 1.5h, and the water content of control sample 3 was significantly lower than that of test sample 4 after 1.5h, indicating that the water-holding capacity of test sample 4 was higher than that of control sample 3.

It can be seen from the combination of table 2 and fig. 1 of this experiment that the moisturizing capabilities of the sample samples 1-6 are generally higher than those of the control samples 1-3. Thus, samples 1-6 can significantly increase the water content of the stratum corneum as seen from the curve.

And (3) test III: radical scavenging test

Test subjects: the cleaning composition obtained in example 4 was used as test sample 4; the cleaning compositions prepared in comparative examples 1-3 were used as control samples 1-3.

The test method comprises the following steps:

the experiment is based on the characteristic that DPPH free radical has single electron, strong absorption is generated at 517nm, and alcoholic solution is purple. In the presence of a free radical scavenger, its absorption gradually disappears by pairing with its single electron, and its degree of discoloration is quantitatively related to the number of electrons it receives, so that a rapid quantitative analysis can be performed with a spectrophotometer.

Preparing the tested test sample 1 and the control samples 1-3 into solutions with mass concentrations of 0.1mg/ml, 0.2mg/ml, 0.4mg/ml, 0.6mg/ml and 0.8mg/ml by using distilled water respectively, adding 2ml of diluent and 2ml of 0.2mg/ml DPPH 50% ethanol solution into the same test tube, shaking uniformly, standing for 30min in a closed manner at room temperature, measuring absorbance at a wavelength of 517nm, and calculating the removal rate, thereby evaluating and discussing the antioxidant capacity of the refined carving, namely the face moistening essence milk and other products.

A ₀ the absorbance was DPPH.50% ethanol solution + distilled water.

TABLE 6

TABLE 7 measurement results of radical scavenging rates of test sample 4 and control sample 1

And (3) test results: as can be seen in table 6, table 7 and fig. 5, the ability to scavenge free radicals becomes stronger with increasing concentration. The curves for control sample 1 and control sample 2 mostly coincide, with clearance for control sample 1 being less than control sample 2 between concentrations of 0.1mg/ml and 0.2 mg/ml. The curve of the control sample 3 is relatively zigzag, the clearance rate of the control sample 3 is greater than that of the control sample 1 within the concentration range of 0.1mg/ml to 0.3 mg/ml; between 0.4mg/ml and 0.8mg/ml, the clearance of control sample 3 was less than that of test sample 4. The clearance curve for test sample 4 is much higher than the clearance curves for control samples 1-3.

Compared with the control samples 1-3, the highest clearance is the test sample 4, the second is the control sample 3 and the control sample 2, and the lowest clearance is the control sample 1 between the concentrations of 0.2mg/ml and 0.4 mg/ml. The greater the clearance, the greater the antioxidant capacity, so the antioxidant capacity is in turn test sample 4 > control sample 3 > control sample 2 > control sample 1. At higher concentrations, the highest clearance was found in test sample 4, the worst was found in control sample 3, and the clearance was not much different between control samples 1 and 2.

From this, it can be seen that the antioxidant ability of the test sample 4 of the present application is far stronger than that of the control samples 1 to 3.
