Description

Technical Field

[0001] The invention belongs to the field of daily chemicals, and particularly relates to a head care composition containing a spikenard root extract. Background Art

[0002] According to the "2023 National Scalp Care Health White Paper", there are three main scalp problems commonly encountered by consumers: greasy, hair loss, and dryness. Although the oil secreted by the scalp can moisturize the hair, if the secretion is too much, it is easy to induce dandruff, dermatitis, and even hair loss. When using shampoo products to clean the scalp, excessive cleaning, incomplete cleaning resulting in surfactant residues on the scalp, or scratching hard may aggravate scalp problems and disrupt the balance of scalp microorganisms. In addition, daily perming and dyeing, ultraviolet rays, and air pollutants can easily cause hair damage, causing the protein in the hair to decompose and nutrients to be lost, resulting in rough, yellow, dry, dull, lack of elasticity, and even easy to break. These injuries may also indirectly affect the health of the scalp. Therefore, more and more consumers prefer hair care products that can solve scalp health problems such as dandruff, strong oil secretion, severe hair loss, and dry, frizzy, and yellow hair. Currently, hair care products on the market usually use dimethyl silicone oil to make hair smooth and shiny, but long-term use may cause the silicone oil to deposit on the hair, forming a thick oil film, making the hair greasy and the effect is poor, which does not solve the existing hair problems well.

[0003] Therefore, there is an urgent need to develop a head care product containing plant-derived active ingredients, which can not only improve the imbalance of scalp microecology, provide a good growth environment for hair, and solve the problems of dullness, dryness, hardening and brittleness, split ends and breakage, and frizziness caused by loss of nutrition, but also give hair better conditioning, improve hair quality, and enhance hair gloss. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a head care composition containing a root extract of Nardostachys grandiflora.

[0045] Wherein, the freezing time is 18 hours.

[0046] The finished product yield of the Nardostachys grandiflora root extract obtained by the above preparation method is 82.18%.

[0047] The Nardostachys grandiflora root extract prepared as above was applied to prepare the head care compositions of Examples and Comparative Examples. The specific formulas of the head care compositions of Examples 1-3 and Comparative Examples 1-4 are shown in Table 1 below.

[0048] Table 1:

[0049]

[0050] In an optional embodiment, the preparation method of each head care composition can be conventional mixing and stirring in the art, but the present invention is not limited thereto.

[0051] The preparation method of the head care composition of the above embodiment comprises the following steps:

[0052] S1. Mix the root extract of Nardostachys grandiflora and hot water evenly and keep warm at 80°C;

[0053] S2. After cooling to 40°C, add hair conditioner (cetrimonium chloride, polyquaternium-7, quaternium-80) and snail extract and stir evenly;

[0054] S3. Continue to add ethanol, anti-dandruff factor (ADS anti-dandruff agent), chelating agent (EDTA-2Na), hair moisturizer (1,3-butylene glycol), preservatives (phenoxyethanol, sodium benzoate), and fragrance, stir evenly, add pH adjuster (lactic acid) to adjust the pH value to 4.5-5.0, and obtain a head care composition containing nard root extract.

[0055] The preparation method of the head care composition of the comparative example can be obtained in the same way.

[0056] Using in vitro hair bundles, the head care compositions prepared in Examples 1-3 and Comparative Examples 1-4 were subjected to laboratory instrument efficacy evaluation and consumer sensory evaluation. The evaluation results are shown in Table 2.

[0057] The experimental instrument efficacy evaluation includes: washing and drying the separated hair bundles for use, treating the separated hair bundles with the hair care compositions prepared in the above-mentioned embodiments and comparative examples, and then rinsing with water and drying. Testing the dry and wet combing properties, oil control, tensile strength, glossiness, and scalp moisture content of the separated hair bundles before and after treatment with the hair care compositions using the experimental instrument, and calculating the change rate based on the before and after test data. Change rate (%) = (data after treatment - data before treatment) / data before treatment.

[0058] The consumer sensory evaluation includes: selecting 35 female volunteers with medium and long hair, randomly dividing them into 7 groups, and trial-using the hair care compositions of the embodiments and comparative examples for two weeks. During the trial period, the hair was washed every two days, and after washing the hair with the same shampoo product, an appropriate amount of the hair care composition was applied, and then rinsed with water. The volunteers scored the scalp irritation, scalp dryness, anti-dandruff effect and other indicators of the hair care composition according to their own feelings of use, with the highest score being 10 points, and the higher the score, the better the effect, and all the results were added up and the average was taken.

[0059] Table 2:

[0060]

[0061] As can be seen from Table 2, compared with Comparative Examples 1-3 in which no spikenard root extract and / or snail extract are added, Examples 1-3 of the present invention have a synergistic effect by combining spikenard root extract and snail extract and applying them to a head care composition containing ethanol, a hair conditioner, an anti-dandruff factor, and a hair moisturizer, thereby obtaining more excellent oil control and moisturizing, improving the combing of dry and wet hair, enhancing the glossiness of hair, anti-oxidation, and preventing hair breakage. The applicant unexpectedly discovered that the technical effect of combining spikenard root extract and snail extract and applying them to a head care composition is superior to the sum of the effects of applying spikenard root extract and snail extract alone to the head care composition. The head care compositions of Examples 1-3 have a good conditioning effect on the combing of dry and wet hair, reduce scalp irritation, enhance the suppleness of hair, and control oil, remove dandruff, and moisturize. They can provide a good growth environment for the scalp microecology and reduce scalp irritation. The best preferred proportion of the head care composition of the present invention is 2-5% of nard root extract, 0.5-2.5% of snail extract, 1-6% of ethanol, 0.1-3% of hair conditioner, 0.5-1.2% of anti-dandruff factor, 1-5% of hair moisturizer, and the balance of deionized water.

[0062] Compared with Example 3, Comparative Example 4 selects to apply the snail extract and the wheat bran extract in combination in the head care composition. It can be found that compared with Example 3, the composition of Comparative Example 4 has a very obvious difference in improving the dry and wet hair combing properties, tensile strength, hair glossiness and scalp moisture content of the hair. At the same time, the composition of Comparative Example 4 will slightly increase the irritation to the scalp, and even has a greater adverse effect on the dry and wet hair combing properties and oil control effect.

[0063] In summary, the present invention obtains a head care composition with excellent antioxidant and antibacterial effects on the scalp and hair by rationally constructing the composition system and selecting and controlling the key parameters of the raw materials. The head care composition has the effects of antioxidant, anti-hair breakage, oil control and moisturizing, and can solve the problems of scalp itching, dry hair, frizzy and easy breakage, split ends, etc., while giving the hair better dry and wet combing properties and improving the hair gloss.

[0064] The preferred embodiments of the present invention are described in detail above. However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, a variety of simple modifications can be made to the technical solution of the present invention, and these simple modifications all belong to the protection scope of the present invention.

[0065] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present invention will not further describe various possible combinations.

[0066] In addition, various embodiments of the present invention may be arbitrarily combined, and as long as they do not violate the concept of the present invention, they should also be regarded as the contents disclosed by the present invention.
