Description

Technical Field

[0001] The invention relates to a double nanometer composition capable of repairing, stabilizing and resisting skin aging and a preparation method thereof. Background Art

[0002] With the changes in modern lifestyles, especially in urban environments, women's skin faces increasingly complex challenges. Urban women are usually exposed to pollution, ultraviolet rays, pressure, air conditioning and dry environments for a long time, which leads to the diversification and complexity of skin problems. Especially under the interaction between the physiological structure of the skin and environmental changes, urban women's skin often has the following three major problems: problematic skin, hormone-dependent skin and damaged skin. These problems directly affect the health and beauty of the skin.

[0003] In the context of the above problems, moisturizing has become one of the core needs of modern skin care. Urban women's skin often lacks sufficient moisturizing factors, resulting in rapid water loss, long-term dryness, and prone to fine lines, cracks, tightness and other problems. Especially in dry or extreme climate environments, the skin's hydration is more fragile and requires more in-depth repair and moisturizing care.

[0004] Although many skin care products on the market have certain moisturizing and repairing functions, they often face the following technical challenges:

[0005] Moisturizing effect is not long-lasting: Many products only form a moisturizing film on the surface, but cannot penetrate deep into the skin to provide lasting moisture and nourishment. The moisturizing factors are few and unstable, making it difficult to keep the skin moisturized and soft for a long time.

[0006] Irritating ingredients and allergic reactions: The chemical ingredients used in some skin care products may cause skin allergies, especially for sensitive skin or hormone-dependent skin, which is more likely to produce adverse reactions. These products may cause uncomfortable symptoms such as dryness, redness, itching, etc., further damaging skin health.

[0007] Insufficient skin barrier repair: Most commercially available skin care products can relieve dryness and sensitivity symptoms in the short term, but have limited effect in repairing the skin barrier function. Once the skin is stimulated or damaged by external factors, it is difficult for traditional skin care products to fundamentally repair the skin barrier, and long-term use may make the skin more fragile.

[0008] Insufficient special care for hormone-dependent skin: There is a lack of targeted and mild skin care products on the market for hormone-dependent skin. Existing products often fail to effectively regulate the skin's internal and external environment to avoid excessive stimulation and dependence, resulting in a violent reaction after hormone withdrawal, and even further aggravation of skin damage. Summary of the invention

[0009] The purpose of the present invention is to provide a dual nanocomposition that can repair, stabilize and resist skin aging and a preparation method thereof, which can provide a comprehensive skin care solution for urban women, effectively alleviate the troubles of problematic skin, hormone-dependent skin and damaged skin, restore the skin's moisture, smoothness and health, and meet the needs of modern women for efficient, safe and deep care.

[0010] The technical solution adopted by the present invention to solve its technical problem is:

[0011] A dual nano-composite for repairing, stabilizing and anti-aging the skin, comprising: nano-diamonds, nano-gold, avocado oil, tocopherol, ectoine, calendula extract, panthenol, xylitol moisturizer, sodium hyaluronate, saccharide isomers, panthenol, saccharide isomers, 1,3-propylene glycol, citric acid, sodium citrate, sodium sulfite and water.

[0012] Preferably, nanodiamond: 0.1%-1.0%, nanogold: 0.1%-0.5%, avocado oil: 1.0%-5.0%, tocopherol: 0.1%-1.0%, ectoine: 0.05%-1.0%, calendula extract: 0.1%-2.0%, panthenol: 0.1%-2.0%, xylitol moisturizer: 0.5%-2.0%, sodium hyaluronate: 0.1%-1.0%, carbohydrate isomers: 0.1%-2.0%, 1,3-propylene glycol: 1.0%-5.0%, citric acid: 0.05%-0.5%, sodium citrate: 0.1%-0.5%, sodium sulfite: 0.05%-0.2%, and the balance is water.

[0013] Preferably, the particle size of the nano-diamond is 10-100 nanometers.

[0014] Preferably, the particle size of the nano-gold is 10-50 nanometers.

[0015] Preferably, the avocado oil is pure natural oil extracted by cold pressing.

[0016] Preferably, the tocopherol is vitamin E from natural sources.

[0017] Preferably, the calendula extract is calendula petal extract.

[0018] Preferably, the molecular weight of the sodium hyaluronate is 5000-10000 Daltons.

[0019] Another technical problem to be solved by the present invention is to provide a method for preparing a dual nanocomposite capable of repairing, stabilizing and anti-aging the skin, comprising the following steps:

[0020] Dispersing nano-gold and nano-diamond in water respectively, and subjecting the nano-gold to an ultrasonic treatment, so that the nano-gold particle size is 5-30 nanometers and the nano-diamond particle size is 10-50 nanometers, ensuring that they are evenly dispersed;

[0021] Dissolve sodium hyaluronate, xylitol moisturizer, 1,3-propylene glycol, sodium citrate, sodium sulfite and sugar isomers in water and stir evenly to form an aqueous phase;

[0022] Mix avocado oil, tocopherol, ectoine, calendula extract, and panthenol, and heat to 50-60°C to ensure that they are completely dissolved to form an oil phase;

[0023] Slowly add the water phase into the oil phase and emulsify using high-speed stirring or an emulsifier to form an emulsion;

[0024] Slowly add the prepared nano-gold and nano-diamond into the emulsion and continue stirring;

[0025] Use citric acid to adjust the pH of the lotion to 4.5-5.5;

[0026] The mixed emulsion was cooled to room temperature and filtered using a 0.22 micron filter to remove insoluble matter and impurities to obtain the final product.

[0027] Preferably, the power of the ultrasonic treatment is 50-200 W, and the treatment time is 5-15 minutes.

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

[0029] Nanodiamonds and nanogold, as nano-scale particles, can penetrate deep into the skin, promote blood circulation, and accelerate cell metabolism and regeneration. Nanodiamonds have strong antioxidant capacity, which can effectively neutralize free radicals, slow down skin aging, improve skin texture, and enhance skin barrier function; Ecdoin helps to enhance skin hydration, promote cell repair, and effectively reduce the skin's reaction to external stimuli. It is a powerful moisturizing factor and can help stabilize the skin's barrier function and resist external environmental pressure.

[0030] Nanogold has a significant anti-aging effect, can improve skin elasticity, promote collagen synthesis, and reduce the formation of fine lines and wrinkles. It can also activate the self-repair function of skin cells and resist oxidative damage during the aging process; tocopherol, as a powerful antioxidant ingredient, can remove free radicals and prevent skin aging caused by external factors such as ultraviolet rays and pollution. It can also enhance the skin's barrier function, delay the aging process, and keep the skin young.

[0031] As an excellent moisturizer, sodium hyaluronate can form a protective film on the skin surface, lock in moisture, keep the skin moisturized, and relieve dryness and dehydration. Its efficient water absorption ability helps the skin stay moisturized for a long time; xylitol moisturizer has moisturizing and soothing effects, can penetrate deep into the skin surface to retain moisture, reduce skin moisture loss, and avoid irritation caused by dryness; sugar isomers and panthenol also help keep the skin moist and soft, promote skin hydration, and enhance skin barrier function.

[0032] Calendula extract is a natural plant ingredient with strong anti-inflammatory and anti-allergic effects. It can soothe the skin, reduce discomfort such as redness, swelling and itching, and improve adverse skin reactions caused by skin sensitivity or external stimuli; the addition of citric acid and sodium citrate can not only adjust the pH value of the formula, but also gently remove aging cuticles, promote skin renewal, and enhance skin smoothness and brightness; sodium sulfite, as an antioxidant ingredient, helps prevent the skin from being damaged by environmental pollutants, while reducing pigmentation and promoting skin recovery.

[0033] Avocado oil is rich in vitamins and fatty acids, which can nourish and repair dry, damaged skin, and improve skin radiance and elasticity. It helps keep the skin soft and strengthens the skin's natural barrier function; 1,3-propylene glycol, as a moisturizer, can effectively moisturize and enhance the penetration of other active ingredients, enhancing the effect of the entire formula.
