Anti-aging composition and preparation method and application thereof

Technical Field

The invention relates to the technical field of skin care products, in particular to an anti-aging composition and a preparation method and application thereof.

Background

Aging is a natural phenomenon that human beings have to undergo in life, and is a very complex physiological process, and aging can be divided into two categories: physiological aging and pathological aging. Physiological aging refers to a physiological degenerative process occurring after the maturation period, and pathological aging is a change in aging due to various external factors (including diseases, environments, living habits, etc.).

With the progress and development of society, people live more and more at night, people stay up more and more at night, and long-term bad work and rest bring various skin problems. The skin aging is accelerated, collagen is lost, water is deficient and dry, the skin color is dark, and sensitivity, acne and the like are caused after the skin is decocted all the time.

The anti-aging products on the market at present have a wide range, few and few anti-aging products after being absorbed in the night, and the problems that active ingredients are easy to run off or unstable in the long-term use process of the anti-aging products at present affect the use of the anti-aging products.

(1) the anti-aging composition provided by the invention can effectively repair damaged skin after being decocted for a long time by using the combined action of hydrolyzed sodium hyaluronate, ectoin, hydroxyethyl piperazine ethanesulfonic acid, polypeptide and the like, and can delay aging after being used daily for a long time.

(2) The invention uses the ultralow molecular hydrolyzed sodium hyaluronate as an anti-aging component, has the effects of promoting cell proliferation, wound repair, skin photodamage repair, free radical removal, transdermal absorption and the like, and the traditional macromolecular sodium hyaluronate only has water retention, viscoelasticity and lubricity.

(3) In addition, the invention also adds the combined action of ectoin, hydroxyethyl piperazine ethane sulfonic acid and polypeptide, wherein the ectoin can play the roles of anti-inflammation, anti-allergy, anti-pollution, anti-photoaging, anti-wrinkle and long-acting moisture retention, and can comprehensively protect, prevent, repair and strengthen the skin; the hydroxyethyl piperazine ethanesulfonic acid can mildly promote the old keratinocyte peeling of the epidermis of the skin, thereby smoothing and softening the skin and brightening the skin color; the acetyl tetrapeptide-2 can induce the synthesis of elastin and type I collagen, improve the cohesion and tightness of skin and rebuild a dermis structure, thereby achieving the effects of delaying senility and resisting senility.

(4) The anti-aging composition prepared by the invention not only plays a role in repairing damaged skin after staying up, but also has the effects of delaying aging, brightening skin color, moisturizing and moisturizing, and plays multiple skin care roles.

(5) The invention also adds the components such as compound grease and the like, and the anti-aging components act on the skin, so that the effects of moistening the skin and forming a film can be achieved, the permeation and absorption of the anti-aging components are promoted, and the water loss is reduced, thereby achieving the long-acting anti-aging effect.

(6) Because the oil solubility of the compound grease is different from the water solubility of the anti-aging ingredients, the emulsifier and the humectant are respectively added to promote the emulsification and dissolution of the compound grease and the anti-aging ingredients in the water carrier and promote the compound grease and the emulsifier to be dispersed in water to form tiny emulsified liquid drops, thereby avoiding the existence of visible particles in the composition.

(7) In addition, by selecting a proper emulsifier and performing combined action with the compound grease formed by the silicone oil and the natural grease, the obtained composition has high stability, does not generate emulsification layering, off-flavor and color change under the conditions of long-time light, high temperature, low temperature and the like, avoids aggregation of small particles in the composition, and ensures stable appearance.

(8) In addition, the inventor finds that although the polypeptide, such as acetyl tetrapeptide-2 and the like, has better water solubility, compared with the polypeptide which is mixed and homogenized with other anti-aging components to form phase A, the polypeptide has higher anti-aging, repairing and moisturizing effects when being added finally.

Anti-aging component

In one embodiment, the anti-aging ingredient of the present invention comprises at least one of hydrolyzed sodium hyaluronate, ectoin, hydroxyethylpiperazine ethanesulfonic acid, and polypeptide.

The chemical formula of the hydrolyzed sodium hyaluronate is (C)₁₄H₂₀NO₁₁Na)_nThe collagen protein is an inherent component in a human body, is a glucan aldehydic acid, is easy to be absorbed through skin, can permeate into a corium layer, promotes blood microcirculation, regulates skin metabolism, improves skin nutrition, has the functions of resisting wrinkles, beautifying, protecting health, preventing skin aging and maintaining collagen protein. In one embodiment, the hydrolyzed sodium hyaluronate has a weight average molecular weight of less than 10000 and a degree of polymerization of less than 25; preferably 5000 to 10000, excluding 10000. In one embodiment, the hydrolyzed sodium hyaluronate is obtained from Huaxi Biotech corporation (weight average molecular weight 8926, degree of polymerization less than 25)

The molecular weight is the weight average molecular weight, statistically averaged over the molecular weight. The average value of the number of repeating units contained in the macromolecular chain of the polymer is the degree of polymerization. In the hydrolyzed sodium hyaluronate, the size of one molecular repeating unit is about 1nm, the polymerization degree of the hydrolyzed sodium hyaluronate is controlled to be less than 25, namely the size of the hydrolyzed sodium hyaluronate is controlled to be less than 25nm, the moisture retention and anti-aging performance is exerted, meanwhile, the sticky feeling of the skin is avoided, and the inventor finds that the low molecular hydrolyzed sodium hyaluronate is also beneficial to the high and low temperature and illumination stability of the composition, and the gel state aggregation of the composition is avoided to form small particles.

Ectoin (Ectoin), also known as 2-methyl-1, 4,5,6, -tetrahydropyrimidine-4-carboxylic acid, is an amino acid derivative and belongs to an extreme enzyme component. Ectoin (Ectoin) is a strongly hydrophilic substance. These small amino acid derivatives bind to their surrounding water molecules and produce the so-called "Ectoin hydroelectrical complexation". These complexes then once again surround cells, enzymes, proteins and other biomolecules, forming a protective, nourishing and stable hydrated shell around them. The excellent stability and protection of ectoin bring about visible and long-term anti-aging effects to our skin, promote the sustained enhancement of skin functions such as increasing elasticity, reducing wrinkles or improving skin roughness, and restore and regulate the moisture content of the skin by repairing the skin. Ectoin also calms and soothes irritated and damaged skin, and promotes skin regeneration.

Hydroxyethyl piperazine ethane sulfonic acid (Bioactive HES) is a very effective biological buffer, can reform the stratum corneum, promotes the metabolism of skin keratinocytes, and is an important flexible exfoliating component; the weakly acidic system, like keratolytic enzyme, macromolecular fruit acid, etc., can soften cutin, but can very gently promote the peeling of old cutin cells of the skin epidermis. The skin can be smooth and soft, the skin color can be brightened, and the absorption of functional components can be promoted; absorb ultraviolet rays and partial visible light and synergistically prevent sunlight.

Examples of polypeptides, including but not limited to acetyl tetrapeptide-2, acetyl tetrapeptide-5, acetyl hexapeptide-8, palm tetrapeptide-7, preferably acetyl tetrapeptide-2, promote the growth and differentiation of keratinocytes, enhance the immune defenses of the skin and promote epidermal regeneration, and enhance the immune system of the skin. In one embodiment, the acetyl tetrapeptide-2 is purchased from Lipotec, spain.
