Description

Technical Field

[0001] The present invention relates to the technical field of cosmetics, and particularly relates to an anti-aging cosmetic composition, a preparation method thereof, and an application thereof. Background Art

[0002] With the continuous improvement of people's attention to skin health and beauty, the anti-aging cosmetics market has developed rapidly. Traditional anti-aging cosmetics mostly rely on natural plant extracts or chemically synthesized antioxidants. Traditional anti-aging ingredients (such as retinoic acid and single collagen) have problems such as strong irritation and high molecular weight, which are difficult to absorb. At the same time, the action targets of single active ingredients are limited, and it is difficult to achieve multi-path anti-aging. Chinese Patent CN202310289264.2 discloses the application of collagen tripeptide in post-sun repair skin care products; Chinese Patent CN202411355106.3 discloses that collagen tripeptide provides nourishing and moisturizing effects in skin care products; Chinese Patent CN202011483838.2 discloses a natural anti-aging mask prepared with alginate oligosaccharide and volcanic rock mud as the main raw materials, supplemented with milk essence, edible glycerin, vitamin E, etc., which has strong antioxidant and moisturizing effects; however, the anti-aging effects of the above three patents are not ideal.

[0003] In summary, there is a need to provide a cosmetic composition with excellent anti-aging effect. Summary of the Invention

[0004] In order to solve the above technical problems existing in the prior art, the present invention provides an anti-aging cosmetic composition, a preparation method thereof, and an application thereof.

[0005] The technical solution of the present invention to solve the above technical problems is as follows:

[0006] The first aspect of the present invention is to provide an anti-aging cosmetic composition, comprising a collagen tripeptide-alginate oligosaccharide complex, and the collagen tripeptide-alginate oligosaccharide complex comprises collagen tripeptide and alginate oligosaccharide.

[0007] As a small molecule active peptide, after being absorbed by the skin, collagen tripeptide stimulates the proliferation of fibroblasts, promotes the production of type I and type III collagen, thereby increasing the skin thickness and elasticity; collagen tripeptide contains natural hydrophilic groups, can lock in moisture, and maintain the skin in a moist state; at the same time, it can repair damaged collagen fibers, reduce the depth of fine lines and wrinkles; it also reduces the excessive decomposition of collagen by regulating the activity of matrix metalloproteinases (MMPs). Alginate oligosaccharide molecules have strong hygroscopicity, can form a water-retaining film, enhance the water-locking ability of the stratum corneum, and relieve pseudo-wrinkles caused by dryness; alginate oligosaccharide can scavenge free radicals, inhibit the damage of oxidative stress to collagen; at the same time, by regulating inflammatory factors (such as IL-6), it reduces the collagen degradation caused by skin inflammation.

[0008] Algooligosaccharide can be used as a carrier to form a complex with collagen tripeptide through hydrogen bonding, improving the transdermal absorption rate of collagen tripeptide. The two can play a synergistic effect:

[0009] 1. Collagen tripeptide directly stimulates collagen synthesis, while algooligosaccharide reduces collagen degradation through antioxidant and anti-inflammatory effects. The two maintain collagen homeostasis from the two directions of "generation - degradation";

[0010] 2. Collagen tripeptide activates the TGF-β / Smad pathway to promote fibroblasts to secrete collagen; Algooligosaccharide reduces inflammatory interference by inhibiting the NF-κB (κ-light chain enhancer of activated B cells) pathway and prolongs the collagen degradation cycle;

[0011] 3. Algooligosaccharide inhibits ultraviolet-induced ERK (extracellular regulated protein kinases) phosphorylation and reduces photoaging damage, while collagen tripeptide enhances cell viability through the PI-3K-Akt signaling pathway. The two work together to form a synergistic effect for photoaging protection;

[0012] 4. The moisturizing effect of algooligosaccharide maintains the skin microenvironment moist and provides suitable conditions for the activity of collagen tripeptide to play;

[0013] 5. Collagen tripeptide fills the gaps in the dermis, and algooligosaccharide strengthens the epidermal barrier. The two jointly improve skin firmness and texture.

[0014] Based on the above technical solutions, the present invention can also be improved as follows:

[0015] Further, by mass percentage, it includes the following components: collagen tripeptide 0.05 - 3.0%, algooligosaccharide 0.1 - 5%, solvent 10 - 20%, oil 15 - 25%, emulsifier 5 - 12%, thickener 0.3 - 0.7%, preservative 0.4 - 0.8%.

[0016] Further, by mass percentage, the components are: collagen tripeptide 0.05 - 3.0%, algooligosaccharide 0.1 - 5%, solvent 10 - 20%, oil 15 - 25%, emulsifier 5 - 12%, thickener 0.3 - 0.7%, preservative 0.4 - 0.8%, and the balance is water.

[0017] Further, the mass ratio of the collagen tripeptide to the algooligosaccharide is 1:2 - 7.

[0018] The beneficial effect of adopting the above further technical solution is that: the mass ratio of collagen tripeptide to algooligosaccharide is limited within the range of 1:2 - 7, which increases the synthesis amount of elastic fibers and collagen fibers and improves the anti-aging effect.

[0019] Further, the molecular weight of the collagen tripeptide is 180 - 500 Da, and the degree of polymerization of the algooligosaccharide is 2 - 10.

[0020] The beneficial effects of adopting the above further technical solution are as follows: Collagen tripeptide with a molecular weight of 180 - 500 Da can penetrate the stratum corneum and play a role directly in the dermis layer; algooligosaccharide with a degree of polymerization of 2 - 10 has a simple structure and no complex spatial conformation, and the risk of allergy is lower.

[0021] Further, the collagen tripeptide - algooligosaccharide complex is prepared by the gradient cooling method.

[0022] Further, the gradient cooling method is carried out successively at 4°C and -20°C.

[0023] The beneficial effects of adopting the above further technical solution are as follows: By adopting the gradient cooling method, the collagen tripeptide - algooligosaccharide complex is stabilized.

[0024] The beneficial effects of adopting the above further technical solution are as follows: The collagen tripeptide - algooligosaccharide complex is stabilized to form a molecular self - assembly structure.

[0025] Further, the solvent is selected from at least one of water, glycerol, and diglycerol; the oil is selected from at least one of squalane, jojoba seed oil, mineral oil, and polydimethylsiloxane; the emulsifier is selected from at least one of C12 - 20 acid PEG - 8 ester, glyceryl stearate, PEG - 75 stearate, ceteth - 20, and steareth - 20; the thickener is selected from at least one of acryloyldimethyltaurate / VP copolymer and carbomer resin; the preservative is selected from at least one of phenoxyethanol and methylparaben.

[0026] The second aspect of the present invention is to provide a preparation method of the above - mentioned anti - aging cosmetic composition, which includes the following steps:

[0027] (1) According to the mass percentage, weigh collagen tripeptide and algooligosaccharide, dissolve them in deionized water, carry out gradient cooling treatment, and thaw at room temperature to obtain a collagen tripeptide - algooligosaccharide complex; weigh oil, emulsifier, and thickener and mix them, heat to obtain an oil phase; weigh solvent and water and mix them, heat.

[0028] (2) Add the aqueous phase to the oil phase and mix evenly, carry out homogenizing emulsification treatment, adjust the pH to 5.5 - 7.0, cool down, add the collagen tripeptide - algooligosaccharide complex, then add the preservative, discharge, age, fill, and package.

[0029] Further, the gradient cooling treatment includes the following technological steps: First, maintain at 4°C for 2 h, and then freeze at -20°C for 1 h.

[0030] Another aspect of the present invention is to provide the application of the above - mentioned anti - aging cosmetic composition in essence or cream.

[0031] Compared with the prior art, the present invention has the following technical effects:

[0032] Collagen tripeptide and algal oligosaccharide act synergistically, having a significant effect on anti-aging of the skin, and at the same time, having high safety and good stability; the preparation method is simple and efficient, and is suitable for industrial production.
