Description

Technical Field

[0001] The invention belongs to the technical field of cosmetics, and particularly relates to an essence containing liquorice root concentrate and a preparation method thereof. Background Art

[0002] Licorice root, known as the "king of herbs", is rich in whitening and antioxidant ingredients, which are the core strength of this essence. This product combines four major effects: whitening and brightening, anti-oxidation and anti-aging, deep hydration and repair. Through core plant extracts and synergistic ingredients, it can effectively inhibit melanin and brighten the skin tone, while providing powerful antioxidant and anti-aging effects, and can achieve the effect of deep hydration and skin repair. Summary of the invention

[0003] The present invention discloses an essence containing licorice root concentrate and a preparation method thereof. Aiming at the deficiencies existing in the prior art, the present invention provides a licorice root essence, which adopts a herbal formula, through core plant extracts and synergistic ingredients, can effectively inhibit melanin, brighten skin tone, provide powerful anti-oxidation and anti-aging effects, and deeply hydrate and repair the skin.

[0004] The present invention achieves the purpose through the following detailed technical solutions:

[0005] A liquorice root extract essence, the composition of which contains liquorice root extract: the liquorice root extract is prepared by the following steps:

[0006] S1. Pretreatment of licorice root: washing, slicing, drying, crushing and sieving the licorice root to obtain licorice root powder;

[0007] S2. Licorice root concentrate extraction: Soak licorice root powder with 2-20 times the weight of water, heat and stir to extract, filter, collect the extract, and concentrate under reduced pressure at low temperature to obtain a licorice root concentrate;

[0008] The liquorice root extract essence comprises plant extracts, 2-5% arbutin extract, 1-4% green tea extract, 0.5-2% echinacea extract, and 0.5-1% ginkgo leaf extract;

[0009] The licorice root extract essence further comprises a moisturizer, which is a mixture of one or more of jojoba oil, squalane, butylene glycol, propylene glycol and glycerin.

[0010] Wherein, the liquorice root extract essence further comprises a thickener, wherein the thickener comprises carbomer with a final concentration of 0.6-1% in the essence;

[0011] The licorice root extract essence further comprises a conditioning agent, niacinamide 0.2-0.5%, sodium hyaluronate (hyaluronic acid) 0.5-2%, collagen peptide 0.5-1%, panthenol (vitamin B5) 0.1-0.5%, retinol palmitate (vitamin A ester) 0.01%-0.1%, coenzyme Q10 0.01-0.05%;

[0012] The licorice root extract essence also includes phenoxyethanol, ethylhexylglycerin and sodium lactate as preservatives and pH regulators.

[0013] The present invention also provides a method for preparing the liquorice root extract essence, which comprises the following steps:

[0014] Step S1, add deionized water, licorice root extract, plant extract, moisturizer, and conditioner into a main pot in sequence, heat to 40-80° C., stir evenly and fully dissolve;

[0015] Step S2, when the temperature drops below 45°C, add a thickener, a preservative, and a pH adjuster, and stir for 10-30 minutes;

[0016] Step S3, cooling to room temperature, filtering the material using a filter screen with a mesh size of 200 or more to obtain an essence.

[0017] The present invention (1) whitens and brightens the skin: the glycyrrhizic acid and arbutin extracts in the licorice root extract have the effect of inhibiting the activity of tyrosinase, which is a key enzyme that controls the production of melanin, and can help reduce the production of melanin, thereby fading spots and even skin color. Niacinamide can inhibit the transport of melanosomes from melanocytes to surrounding keratinocytes, thereby reducing the synthesis of melanin and regulating melanin metabolism. Ultimately, a whitening effect is achieved.

[0018] (2) Anti-inflammatory and soothing: Glycyrrhizic acid and flavonoids in licorice root extract have anti-inflammatory effects and can effectively relieve skin redness, swelling and irritation. They are especially beneficial for patients with sensitive skin and rosacea. They inhibit the release of inflammatory mediators, reduce the inflammatory response of the skin, and help restore the skin's barrier function. Active ingredients in Echinacea extract, such as polysaccharides, polyphenols, alkylamides, and echinacoside, can inhibit the production of inflammatory factors, reduce the infiltration of inflammatory cells, and inhibit cyclooxygenase, thereby helping the skin relieve redness, swelling, pain and other discomforts.

[0019] (3) Anti-aging: Chicoric acid in Echinacea extract shows significant antioxidant and lipid peroxidation resistance. Reactive oxygen plays an important role in promoting the aging process of the human body. Chicoric acid can inhibit the oxidation of low-density lipoprotein by reducing the accumulation of reactive oxygen species (ROS) and lipid peroxide malondialdehyde in cells and scavenging free radicals, thereby improving the body's antioxidant function and playing a role in slowing down aging. Retinyl palmitate can also promote the metabolism of growth factors, thereby improving skin metabolism, promoting the production of collagen in the dermis, increasing skin tension, and helping to delay skin aging. Coenzyme Q10 achieves the purpose of delaying skin aging, reducing wrinkles, and protecting the skin by inhibiting lipid peroxidation, anti-oxidation, and promoting cell metabolism.

[0020] (4) Hydration and repair: Sodium hyaluronate is a highly effective moisturizer that attracts and retains a large amount of water, provides deep hydration to the skin, and helps maintain the skin's moisture balance. Collagen is an important component for maintaining the structure of the skin. Supplementing with collagen peptides helps improve the overall structure of the skin and make it firmer. When sodium hyaluronate and collagen peptides are used together, they can enhance each other and jointly improve the skin care effect. Sodium hyaluronate provides an immediate moisturizing effect, while collagen peptides strengthen the skin's support structure from the inside by promoting collagen production. This combination can not only improve the appearance of the skin, but also enhance the health of the skin, making the skin more youthful and vibrant. DETAILED DESCRIPTION
