Description

Technical Field

[0001] The invention belongs to the field of daily cosmetics, and in particular relates to a nourishing hair care composition and application thereof. Background Art

[0002] Hair is an important part of the human body, affecting a person's appearance and also a manifestation of health. Hair is composed of complex keratin fibers, which are composed of keratin molecules and entangled with each other in a spiral combination. However, in real life, due to improper care such as hair pulling, hair perming, hair dyeing, and long-term ultraviolet radiation, the spiral structure of hair keratin fibers is destroyed, causing the hair to lose its tensile strength and extensibility, resulting in brittle, stiff, split, dry, difficult to comb, etc., and also causing the hair's luster, tension and extensibility to decrease.

[0003] CN106726753A discloses a hair mask and a preparation method thereof. The hair mask provided by the invention comprises the following components and their weight percentages: 1-5% betaine, 10-20% behenyl trimethyl ammonium chloride, 1-5% polydimethylsiloxane, 1-3% menthol, 10-15% moisturizer, 15-25% conditioning agent, 1-5% climbazole, 1-3% patchouli alcohol, 0.1-0.5% EDTA-disodium, 0.1-0.5% citric acid, 0.1-0.5% methylparaben, 0.1-0.5% essence, 1-5% cetyl hydroxyethyl cellulose and 12-58.6% water. The hair mask can repair damaged hair, enhance hair toughness, moisturize scalp and hair, relieve itching and remove dandruff, and is refreshing and comfortable, mild to the skin and non-irritating.

[0004] CN107296787A discloses a deep repairing moisturizing hair mask and its preparation method, comprising the following components in weight percentage: ginseng extract: 5%-30%; cationic conditioning agent: 2.6%-9.5%; thickening emulsifier: 0.7%-3%; fat excipient: 1.8%-8%; hair repair agent: 1.5%-11.5%; anti-allergic agent: 0.1%-1%; moisturizer: 2%-10%; preservative: 0.015%-0.11%; pH regulator: 0.1%-0.5%; essence: 0.5%-1%, and the balance is deionized water. The hair mask provided by the invention is added with a composition of hydrolyzed silk and sericin with deep repairing effect and hydroxyethyl urea and glycerin with high-efficiency moisturizing effect, which can make the hair fully absorb nutrients to achieve the effect of deep repairing hair and keep the hair moisturized and smooth.

[0005] However, the hair masks in the prior art are still not effective in improving the smoothness and glossiness of hair after use. Therefore, developing a product that can improve the smoothness and glossiness of hair and achieve deep nourishment and hair care has become one of the technical problems that need to be solved urgently. Summary of the Invention

[0006] In view of the deficiencies of the prior art, the object of the present invention is to provide a nourishing hair care composition and its application. The nourishing hair care composition has excellent hair nourishing effects and can well improve the softness and gloss of hair strands.

[0007] To achieve the object of the present invention, the following technical solutions are adopted:

[0008] In the first aspect, the present invention provides a nourishing hair care composition, which comprises macadamia nut oil, leontopodium alpinum extract, cetrimonium chloride and glycine.

[0009] Macadamia nut oil is a natural plant component extracted from macadamia nuts (Hawaiian nuts), rich in unsaturated fatty acids, vitamin E and phytosterols, and has effects such as antioxidant, nourishing and softening. Leontopodium alpinum extract is the active ingredient of leontopodium alpinum, rich in active ingredients such as polyphenols and flavonoids, which can reduce the damage of hair caused by environmental pollution or ultraviolet rays, and has effects such as anti-inflammatory and soothing, and toughening. Cetrimonium chloride can adsorb damaged hair strands, reduce hair friction, improve combability, and at the same time can fill the defects of hair scales and has a repair effect. Glycine is a mild amino acid component, which can help hair maintain moisture balance, reduce irritation and participate in keratin maintenance.

[0010] The present invention creatively discovers that macadamia nut oil, leontopodium alpinum extract, cetrimonium chloride and glycine have significant synergistic effects in nourishing hair. Each component cooperates with each other and synergistically enhances the efficacy, and can greatly improve the nourishing and repairing efficacy of the composition.

[0011] Preferably, by mass parts, the nourishing hair care composition comprises 1-10 parts of macadamia nut oil, 0.5-5 parts of leontopodium alpinum extract, 5-20 parts of cetrimonium chloride and 0.5-5 parts of glycine.

[0143] Test Example 1

[0144] Carding force test:

[0145] The carding force refers to the frictional resistance of the hair against the comb. The smaller the carding force, the better the hair softness.

[0146] (1) Samples to be tested: Hair masks prepared in each application example and comparative application example.

[0147] (2) Test method:

[0148] Fix the standard hair bundle to the carding instrument with a splint. After combing 10 times with a comb, measure the carding force (F1) using a hair carding instrument; turn on the shower head to start rinsing, with the water temperature at 40 ± 5°C, and start combing with the comb; then evenly coat 4 ± 0.5 g of the sample to be tested on the standard hair bundle. After 10 minutes, turn on the shower head to start rinsing, and comb 10 times while rinsing; dry the hair in a constant temperature and humidity chamber at a temperature of 21 ± 1°C and a humidity of 50 ± 5% RH, then comb 10 times with a comb, and then measure the carding force (F2) using a hair carding instrument. Calculate the carding force change rate. The test results are shown in Table 2.

[0149] Carding force change rate = (F2 - F1) / F1 × 100%.

[0150] Test Example 2

[0151] Glossiness test:

[0152] (1) Samples to be tested: Hair masks prepared in each application example and comparative application example.

[0153] (2) Test method:

[0154] Select 150 volunteers aged 18 - 45 years with comparable hair volume and hair length, randomly divide them into 15 groups with 10 people in each group, and use the above samples to be tested respectively. Each group of volunteers uses the sample to be tested once every night, 4 ± 0.5 g each time. Using a Novo - Gloss glossiness meter, measure the glossiness of the volunteers' hair on the 0th day and the 15th day respectively, calculate the glossiness change rate. The test results are shown in Table 2.

[0155] Glossiness change rate = (G2 - G1) / G1 × 100%. Where G1 is the average glossiness of the volunteers' hair in each group on the 0th day of the test, and G2 is the average glossiness of the volunteers' hair in each group on the 15th day of the test.
