Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of cosmetics, and particularly relates to a scalp care serum, especially to a plant extract scalp serum taking naringin as a core active ingredient, and also relates to a preparation method of the serum and application of the serum in oil control, anti-inflammatory soothing, barrier repair, hair loss reduction and hair root strengthening. BACKGROUND

[0002] With the acceleration of life pace and the aggravation of environmental pollution, problems such as excessive oil secretion, sensitivity, itching, barrier damage and increased hair loss on the scalp are increasingly common. Currently, commercially available scalp care products have the following defects: first, they mainly focus on cleaning and moisturizing, have single active ingredients, and have limited repair effects on hair follicles and scalp barriers; second, some products contain chemical ingredients and are too irritating for sensitive scalps; and third, natural active ingredients have poor solubility and insufficient stability, and thus cannot achieve actual effects.

[0003] Naringin is a natural flavonoid compound extracted from natural plants such as naringin and bitter orange fruit, and has excellent antioxidant, anti-inflammatory, microcirculation regulating and skin microenvironment improving effects. It is natural, mild and safe, and has high application value in the field of scalp care. In the prior art, naringin is mainly used in food preservation, medicine preparation or general skin care products, and there is no technical solution for compounding naringin with plant extracts in a specific ratio to prepare a special scalp serum and achieving the synergistic effects of oil control, anti-inflammatory, hair loss prevention and barrier repair.

[0004] Therefore, there is an urgent need in the field for a mild, efficient and stable special serum with multiple scalp repair effects to make up for the deficiencies of the prior art. SUMMARY

[0005] 1. Technical problem to be solved In view of the problems of single effect, strong irritation, low utilization rate of natural active substances and poor effect of existing scalp care products, the present application provides a naringin plant extract scalp serum, which achieves the technical effects of natural mildness, synergistic multiple effects, high stability and good penetration and absorption. The preparation method and application of the serum are also provided, which are suitable for industrial production and market application. TECHNICAL SCHEME

[0006] A naringin plant extract scalp serum, which is composed of the following components in percentage by weight: 0.5% to 4.5% of naringin, 2% to 8% of plant extract compound, 3% to 12% of humectant, 1% to 4% of solubilizer, 0.1% to 0.8% of mild preservative, and the balance of deionized water; The plant extract compound is a compound of cypress leaf extract and ginseng extract at a mass ratio of 1:1, or a compound of rosemary extract and ginger extract at a mass ratio of 2:1. The moisturizer is a combination of two or more of glycerin, panthenol, and sodium hyaluronate. The solubilizer is PEG-40 hydrogenated castor oil; The mild preservative is a compound system of phenoxyethanol and ethylhexylglycerin.

[0007] Preferably, the naringin content is 1.5% to 3.5%.

[0008] The present invention also provides a method for preparing the above-mentioned scalp-specific serum, comprising the following steps: (1) Heat deionized water to 45℃~55℃, add humectant and solubilizer in sequence, and stir at 300~500r / min until completely dissolved; (2) Keep the temperature constant, add naringin and plant extract compound extract, and continue stirring for 20-40 minutes until the system is uniform and transparent; (3) Cool down to below 30°C, add mild preservative, stir for 10-15 minutes, filter through a 0.22μm filter membrane to obtain naringin plant extract scalp-specific essence.

[0009] The present invention also provides the use of the above-mentioned essence in the preparation of scalp care products that control oil, reduce inflammation and soothe, repair the scalp barrier, reduce hair loss, and strengthen hair roots. Beneficial effects

[0010] 1. Natural and gentle, non-irritating: With naringin and plant extracts as the core active ingredients, it contains no alcohol, pigments, or irritating preservatives, making it suitable for oily scalps, sensitive scalps, and people with hair loss.

[0011] 2. Synergistic effects of multiple benefits: Naringin exerts anti-inflammatory, antioxidant and scalp microenvironment-regulating effects, and when combined with specific plant extracts, it achieves oil control, strengthens hair roots and repairs the hair barrier, solving a variety of scalp problems.

[0012] 3. Excellent stability and solubility: Through specific formulation and process, the solubility and stability of naringin in aqueous system are significantly improved, and it is not easy to separate, change color or become inactive.

[0013] 4. Fast penetration and absorption: The serum formulation is thin and easily penetrates into the dermis and hair follicles of the scalp, resulting in high utilization of active ingredients.

[0014] 5. Simple process and mass production: The preparation conditions are mild and the steps are simple, requiring no complex equipment, making it suitable for large-scale industrial production. Detailed Implementation Example

[0015] Naringin 1.5%, Platycladus orientalis leaf extract 1.0%, ginseng extract 1.0%, glycerin 5%, panthenol 1.5%, sodium hyaluronate 0.2%, PEG-40 hydrogenated castor oil 1.5%, phenoxyethanol 0.4%, ethylhexylglycerin 0.1%, deionized water to 100%.

[0016] Preparation method: (1) Heat deionized water to 50°C, add glycerin, panthenol, sodium hyaluronate and PEG-40 hydrogenated castor oil, and stir to dissolve; (2) Add naringin, arborvitae leaf extract and ginseng extract, keep warm and stir for 30 minutes; (3) Cool down to 28°C, add phenoxyethanol and ethylhexylglycerin, stir for 15 minutes, and filter to obtain the product. Example

[0017] Naringin 3.0%, rosemary extract 4.0%, ginger root extract 2.0%, glycerin 6%, panthenol 2.0%, PEG-40 hydrogenated castor oil 2.5%, phenoxyethanol 0.4%, ethylhexylglycerin 0.1%, deionized water to 100%.

[0018] The preparation method is the same as in Example 1. Example

[0019] Naringin 2.0%, Platycladus orientalis leaf extract 1.5%, ginseng extract 1.5%, glycerin 4%, sodium hyaluronate 0.15%, PEG-40 hydrogenated castor oil 2.0%, phenoxyethanol 0.4%, ethylhexylglycerin 0.1%, deionized water to 100%.

[0020] The preparation method is the same as in Example 1.

[0021] Comparative Example 1 Compared with Example 1, no naringin was added, but the remaining components, contents, and preparation methods were exactly the same.

[0022] Effect Experiment: Sixty volunteers with oily scalp, sensitive and itchy scalp, and prone to hair loss were randomly divided into four groups. They used the products from Examples 1, 2, and 3, and Comparative Example 1, respectively, once daily for 28 consecutive days. The results are as follows: 1. Sebum secretion: The sebum reduction rate in the example group was 42.6%–58.3%, while that in the comparative group was only 12.1%; 2. Scalp itching score: The itching relief rate in the example group was over 75%, while it was only 23.3% in the control group; 3. Hair loss amount: Hair loss was reduced by 38% to 51% in the example group, while there was no significant improvement in the control group; 4. Safety: No allergic reactions, redness, or irritation were observed in any of the example groups.

[0023] Experimental results show that the essence of this invention is significantly effective in controlling oil, reducing inflammation, reducing hair loss, and repairing the scalp, and is superior to conventional formulas that do not contain naringin, demonstrating outstanding practicality and technical effectiveness.
