Description

Technical Field

[0001] The present invention belongs to the field of daily-use cosmetics, and particularly relates to a composition with the effects of repairing and softening hair and its application. Background Art

[0002] Hair is an important part of the human body, affecting a person's appearance and also being one of the manifestations of health. Hair is composed of complex keratin fibers, and the keratin fibers composed of keratin protein molecules are intertwined with each other through a spiral combination. However, in real life, due to improper care such as hair straightening, perming, and dyeing, as well as long-term ultraviolet radiation, the spiral structure of the hair keratin fibers is damaged, causing the hair to lose its tensile strength and extensibility, resulting in problems such as brittle, stiff, split, dry, and difficult-to-comb hair. At the same time, it also causes a decrease in hair gloss, tension, and stretchability.

[0003] CN110680761A discloses a shampoo, which includes caffeine, plant peptides, and nano gold. The plant peptides are a mixture of oat active peptides and ginkgo active peptides. The shampoo provided by this invention, through the compounding of caffeine, plant peptides, and nano gold, on the one hand, can effectively improve the elasticity and toughness of hair, enabling the hair to obtain excellent hair tensile strength and extensibility, and having better tensile strength; on the other hand, it can also repair the hair with damaged cuticle structures caused by perming, dyeing, etc., having a repair effect, making the cuticle more neat, thereby improving hair brightness and softness, and having the effect of strengthening and nourishing hair.

[0004] CN105997735A discloses a natural hair washing and care product, which includes liposomes of peony seed oil and sea kale leaf extract, hydrolyzed silk protein, and a surfactant. This natural hair washing and care product is formulated with natural ingredients, not only having the function of cleaning and softening hair like ordinary natural shampoos, but also having the function of nourishing hair and repairing damaged hair quality. At the same time, the solubility of natural ingredients is greatly improved. However, the above-mentioned shampoo has complex ingredients and does not provide multiple effects of repairing and softening dry hair strands.

[0005] Therefore, how to develop a composition with the effects of repairing and softening hair, improving the glossiness, softness, and repair ability of hair strands has become an urgent technical problem to be solved at present. Summary of the Invention

[0006] Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide a composition with the effects of repairing and softening hair and its application. This composition can significantly improve the glossiness and softness of hair strands, and at the same time can improve the tensile breaking strength of hair.

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

[0008] In a first aspect, the present invention provides a composition having the efficacy of repairing and softening hair, and the composition comprises honey extract, camellia seed oil, phenylalanine and hydrolyzed keratin.

[0009] Honey extract is an effective substance extracted from honey, containing various nutrients such as sugars, vitamins and minerals, and having multiple effects such as moisturizing and antioxidant. Camellia seed oil is a substance extracted from camellia seeds, which can penetrate deep into the hair and nourish the hair strands, repairing damaged hair cuticles. Phenylalanine belongs to aromatic amino acids and can participate in the metabolic process of proteins in the hair, helping to promote hair growth and repair. Hydrolyzed keratin has good biocompatibility, can effectively repair split hair, reduce and prevent hair splitting, and enhance the strength and elasticity of hair.

[0010] The present invention creatively discovers that honey extract, camellia seed oil, phenylalanine and hydrolyzed keratin cooperate with each other, can improve the gloss and softness of hair bundles, and at the same time can improve the tensile fracture strength of hair, having a significant synergistic effect in terms of repair and softness.

[0167] Test Example 1

[0168] Repair ability test

[0169] (1) Test samples: The shampoos of Application Examples 1 - 10 and Comparative Application Examples 1 - 4.

[0170] (2) Test method: Select 140 volunteers with dry, frizzy, dull hair and neutral scalp. The volunteers' hair is at least 20 cm long and straight. Randomly divide the volunteers into 14 groups of 10 people each, and use the above test samples to wash their hair continuously 10 times at a frequency of 2 days / time, and require to wash the head for 3 minutes each time.

[0171] (3) Test indicators:

[0172] (3.1) Glossiness growth rate test:

[0173] After combing the volunteers' hair neatly, use a glossiness analyzer to measure the glossiness of the hair on the part of the volunteer's head covering the left ear from a 60° measurement angle. Measure each volunteer 3 times and take the average. The test data is divided into two groups, namely the glossiness of the volunteers' hair before using the shampoo and the glossiness of the hair after using the shampoo ten times, and calculate the glossiness growth rate after use. Glossiness growth rate (%) = [(Glossiness after use - Glossiness before use) / Glossiness before use] × 100%, and the test data is shown in Table 5.

[0174] (3.2) Tensile fracture strength enhancement rate test:

[0175] Cut 20 cm long hair from the volunteers' heads, and use a Shanghai Xiangjie XJ810 single - hair tensile property tester to stretch the hair at a tensile speed of 0.01 N and 15 mm / min to test the elongation at break of the hair. Repeat each experiment three times and take the average. The test data is divided into two groups, namely the tensile fracture strength (N) of the volunteers' hair before using the shampoo and the tensile fracture strength (N) of the hair after using the shampoo ten times, and calculate the tensile fracture strength enhancement rate after use. Tensile fracture strength enhancement rate (%) = [(Tensile fracture strength of hair after use - Tensile fracture strength of hair before use) / Tensile fracture strength of hair before use] × 100%, and the test data is shown in Table 5.

[0177]

[0178]

[0179] As can be seen from the data in Table 5, the shampoo involved in the present invention can significantly improve the gloss and tensile breaking strength of hair bundles. From the comparison of the data between Application Example 1 and Comparative Application Examples 1-4, it can be seen that when any one of honey extract, camellia seed oil, phenylalanine or hydrolyzed keratin is missing in the composition, the gloss and tensile breaking strength of the hair strands all decrease to varying degrees, indicating that honey extract, camellia seed oil, phenylalanine and hydrolyzed keratin have significant synergistic effects in terms of repair and softness.

[0180] From the comparison of the data between Application Example 1 and Application Example 4, it can be seen that the honey extract prepared by the microwave extraction method can better exert the repair and softening effects; from the comparison of the data between Application Example 1 and Application Examples 5-6, it can be seen that doping with DAX-8 type and D3520 type macroporous resins to purify the crude honey extract, the prepared honey extract has a more excellent effect on increasing the gloss and tensile breaking strength of the hair strands.

[0181] From the comparison of the data between Application Example 1 and Application Examples 7-9, it can be seen that during the preparation process of camellia seed oil, hemicellulase, pectinase and isoamylase have certain synergistic effects in the enzymatic hydrolysis effect. Enzymatic hydrolysis of camellia seed powder with this composite enzyme can further improve the repair and softening effects of the prepared camellia seed oil; from the comparison of the data between Application Example 1 and Application Example 10, it can be seen that during the preparation process of camellia seed oil, the camellia seed oil obtained by supercritical CO2 extraction can better be compounded with honey extract, phenylalanine and hydrolyzed keratin, thereby improving the gloss and tensile breaking strength of the hair strands.
