Description

Technical Field

[0001] The present invention relates to a ceramide-orchid extract composite composition for thickening the skin barrier and anti-aging, and a preparation method and application thereof. Background Art

[0002] As people's demand for skin health and beauty continues to rise, the skincare industry has undergone technological innovation and improvements in many areas. However, many skincare products currently on the market still have some technical deficiencies, especially in terms of skin barrier repair, anti-aging, deep moisturizing, and formula stability. The following are the main deficiencies of existing technologies:

[0003] The skin barrier is a natural barrier that protects the skin from harmful external substances. Once this barrier function is damaged, the skin is prone to dryness, sensitivity, and allergies. Although some existing skin care products contain moisturizing ingredients such as sodium hyaluronate and glycerin, which can temporarily improve dry skin, their repair effect on the skin barrier is still limited and they cannot effectively enhance the skin's natural barrier function. In particular, after long-term use, the effect may not be obvious, and the skin's hydration and protective functions are still insufficient.

[0004] As we age, the main manifestations of skin aging include sagging, wrinkles, and dullness. While some products on the market claim to have anti-aging effects, most rely on a single antioxidant or moisturizing ingredient, an approach that is often ineffective. Skin aging is a multifactorial, multi-layered process involving free radical damage, collagen loss, decreased skin hydration, and other factors. Consequently, existing skincare products struggle to effectively and comprehensively combat aging and often fail to provide comprehensive anti-aging protection at all levels.

[0005] Many current skincare products have limited active ingredient selection, failing to fully leverage the synergistic effects of their ingredients. For example, ceramides can repair the skin barrier, but when used alone, their effects may not be as expected. Vitamin C derivatives contribute to anti-aging and skin brightening, but their poor stability in water-based formulas can reduce their effectiveness. This failure to fully leverage the synergistic effects of combined active ingredients leads to deficiencies in the effectiveness and stability of existing products.

[0006] The stability of skincare product formulations is a key factor in determining their long-term effectiveness. Many active ingredients in skincare formulations are susceptible to loss of effectiveness due to factors such as oxidation, UV rays, and heat. Furthermore, the compatibility and dispersibility of different active ingredients are also crucial issues in formula stability. Existing formulations can exhibit uneven emulsification, ingredient precipitation, and active ingredient loss, which can affect product performance and stability.

[0007] To ensure that skincare products are free of microbial contamination during long-term use, the use of preservatives is crucial. While existing preservative technologies effectively inhibit microbial growth, some preservative ingredients may cause skin irritation or allergic reactions. Furthermore, some natural preservatives are less effective, leading to formulas that deteriorate quickly after opening. Therefore, ensuring long-term product safety while avoiding skin irritation remains a major challenge for skincare products. Summary of the Invention

[0008] The purpose of the present invention is to provide a ceramide-orchid extract composite composition for skin barrier thickening and anti-aging, as well as its preparation method and application, which solves multiple technical problems such as skin barrier repair, anti-aging, moisturizing, and anti-oxidation, and provides a multifunctional skin care composition that can effectively improve the health of the skin, enhance the skin's barrier function, anti-aging ability and overall appearance.

[0009] The technical solution adopted by the present invention to solve its technical problem is:

[0010] A ceramide-orchid extract composite composition for thickening the skin barrier and anti-aging, comprising the following ingredients: ceramide, orchid extract, vitamin C derivatives, sodium hyaluronate, peptide components, grape seed extract, emulsifier, thickener, pH regulator, preservative, fragrance, glycerin, butylene glycol, and the balance being water.

[0011] Preferably, the following ingredients are included in the following proportions: ceramide 3%-5%, orchid extract 1%-3%, vitamin C derivative 0.5%-2%, sodium hyaluronate 0.5%-1.5%, peptide ingredient 0.5%-2%, grape seed extract 1%-2%, emulsifier 1%-3%, thickener 0.2%-1%, pH adjuster 0.1%-0.3%, preservative 0.5%-1.5%, fragrance 0.1%-0.5%, glycerin 3%-5%, butylene glycol 1%-3%, and the balance is water.

[0012] Preferably, the peptide component is selected from copper peptide, acetyl hexapeptide-8 or a combination thereof.

[0013] Preferably, the sodium hyaluronate is low molecular weight sodium hyaluronate.

[0014] Preferably, the vegetable oil is selected from jojoba oil, grape seed oil or a combination thereof.

[0015] Preferably, the preservative is selected from phenoxyethanol, ethylhexylglycerin or a combination thereof.

[0016] Another technical problem to be solved by the present invention is to provide a method for preparing a ceramide-orchid extract composite composition for thickening the skin barrier and anti-aging, comprising the following steps:

[0017] Add deionized water to a stirring container, add glycerin, butylene glycol, sodium hyaluronate, grape seed extract, and orchid extract, and dissolve under low speed stirring at 25-30°C until the solution is uniform;

[0018] Add vegetable oil, ceramide, and emulsifier to another mixing container and heat to 60°C. Maintain the temperature for 10-15 minutes to dissolve and homogenize the ingredients in the oil phase.

[0019] Slowly add the oil phase to the water phase while keeping stirring. Use high shear stirring to mix the water and oil phases evenly. The shear rate is 5000-10000 rpm and the stirring time is 10-15 minutes to form an emulsion.

[0020] When the emulsion cools to below 45°C, add active ingredients such as peptides, vitamin C derivatives, preservatives, and fragrances and continue stirring to ensure uniform dispersion.

[0021] Add pH regulator to adjust the pH value of the formula to 4.5-6.5;

[0022] Add thickener and continue stirring to ensure that the thickener is completely dissolved and evenly dispersed;

[0023] Once all ingredients are added and mixed, slowly cool to room temperature;

[0024] During the cooling process, continue stirring to ensure the stability and homogeneity of the emulsion;

[0025] The final product is filtered to remove possible impurities and bubbles, and the product is transferred to a sterile packaging container and sealed for storage.

[0026] Preferably, a thickener is added and stirring is continued to ensure that the thickener is completely dissolved and evenly dispersed, so that the viscosity of the emulsion reaches 1000-3000 cP.

[0027] Another technical problem to be solved by the present invention is to provide a ceramide-orchid extract composite composition for skin barrier thickening and anti-aging, which is applied on the skin by skin application or external application to stimulate skin collagen synthesis.

[0028] The beneficial effects of the present invention are:

[0029] This regimen, through the application of ceramide, effectively strengthens the skin's barrier function and repairs the skin's natural barrier structure, thereby improving the skin's barrier capacity, reducing water loss, and enhancing the skin's resistance to external stimuli. The combination of orchid extract and vitamin C derivatives contributes to antioxidant protection, reducing free radical damage to the skin, promoting collagen synthesis, and slowing the aging process. Sodium hyaluronate and grape seed extract, with their powerful moisturizing and antioxidant properties, help maintain skin's elasticity and smoothness, thereby improving the skin's overall appearance.

[0030] Ingredients such as sodium hyaluronate and glycerin can provide deep hydration to the skin, helping to lock in moisture and keep the skin moisturized and plump. These ingredients can significantly enhance the softness, smoothness and elasticity of the skin, effectively reducing problems such as dryness and fine lines; the formula contains a variety of active ingredients, such as ceramides and orchid extracts, which require a good emulsification system to ensure their uniform dispersion and effectiveness. The choice of emulsifiers (such as polysorbate) and thickeners (such as carbomer and xanthan gum) can ensure the uniformity between the ingredients and the stability of the formula, so that the composition can maintain its effectiveness in different environments; the formula contains preservatives (such as phenoxyethanol, ethylhexylglycerin, etc.) to ensure that the preparation will not reduce its effectiveness due to microbial contamination during long-term use, while maintaining safety.
