Description

Technical Field

[0001] The invention belongs to the field of cosmetics, and more specifically, relates to a hair product containing emblica emblica extract, and a preparation method and application thereof. Background Art

[0002] Natural plant hair products are mainly composed of plant extracts (such as emblica, avocado fruit, nail grass, Polygonum multiflorum, etc.), with no or only a small amount of chemical ingredients. They are favored by more and more consumers because of their non-toxic, mild, and non-allergenic characteristics. However, existing natural plant hair products will still cause certain damage to the hair after dyeing, resulting in problems such as easy breakage, poor combing, dull luster, and sensitivity to ultraviolet rays. Therefore, it is very important to develop a natural plant hair product that will not cause obvious damage to the hair. Summary of the invention

[0003] The present invention aims to provide a hair product containing emblica bud extract in view of the deficiencies in the prior art. As a natural plant hair product, the hair product not only has better stability itself, but also can make the dyed hair have better elasticity, combing properties and glossiness, and can also reduce the sensitivity of the dyed hair to ultraviolet rays, indicating that the hair product can greatly reduce the damage to hair caused by dyeing.

[0004] The first object of the present invention is to provide a hair product containing the emblica extract.

[0085] Test Example 1: Stability Test

[0086] The A and / or B agents of Examples 1 to 3 and Comparative Examples 1 to 11 were subjected to low temperature (-5°C ± 2°C), high temperature (45°C ± 2°C), and high and low temperature cycle (first high temperature for 24 hours, then low temperature for 24 hours, as a cycle) tests, and the test duration was 30 days. After the test, the A and / or B agents were observed to see if there were abnormal phenomena such as discoloration and stratification, and the results are shown in Table 1.

[0087] Table 1

[0088]

[0089] It can be seen that the hair products obtained in Examples 1 to 3 did not show abnormal phenomena such as discoloration and stratification in the low temperature, high temperature, and high and low temperature cycle tests, while the hair products obtained in Comparative Examples 1 to 7, 9 to 10, which replaced the different molecular weights of the emblica extracts, different types of emulsifying thickeners, and different types of solubilizing and penetrating agents, both the A agent or the B agent showed more or less instability, that is, the stability of the hair products obtained in Examples 1 to 3 was significantly better than that in Comparative Examples 1 to 7, 9 to 10. This shows that when the molecular weight of the emblica extract is 500 to 1000 Da, it can be compounded with the specific types of emulsifying thickeners, solubilizing and penetrating agents and other ingredients of the present invention to obtain a hair product with better stability.

[0090] Test Example 2 Hair Quality Test

[0091] Hair with relatively consistent initial hair quality was collected and divided into 14 groups, with 3 bundles in each group. The A agents obtained in Examples 1 to 3 and Comparative Examples 1 to 11 were applied to different groups of hair bundles respectively (ensuring that the amount of A agent contacted per unit surface area of ​​all hair bundles was basically the same), and after keeping for 20 minutes, the A agent on the hair was brushed off without washing, and then the B agents obtained in Examples 1 to 3 and Comparative Examples 1 to 11 were applied respectively (ensuring that the amount of B agent contacted per unit surface area of ​​all hair bundles was basically the same), and after keeping for 20 minutes, they were rinsed with clean water, and then wiped dry with a lint-free paper towel, and hung in a constant temperature and humidity environment (temperature 20 to 25° C., humidity 40% to 60%) for 24 hours to dry, and then the following tests were performed:

[0092] (1) Young's modulus is a physical quantity that describes the ability of solid materials to resist deformation. The smaller the value, the more obvious the elasticity. 0.1g of hair was randomly selected from each group of hair bundles and its Young's modulus was first tested using a Young's modulus tester as the Young's modulus before irradiation. The hair was irradiated with ultraviolet light for 200 hours (intensity 5.06mW / cm 2 , wavelength 300-400nm), and then use a Young's modulus tester to test its Young's modulus as the Young's modulus after irradiation. The test was repeated 10 times, and the results were averaged. The Young's modulus increase rate was calculated according to the formula "Young's modulus increase rate (%) = (Young's modulus after irradiation - Young's modulus before irradiation) / Young's modulus before irradiation × 100%" to determine the sensitivity of the dyed hair to ultraviolet rays. The results are shown in Table 2.

[0093] (2) 10 g of hair was randomly selected from each group of hair bundles, and the combing work was measured using a hair combing tester, and the glossiness was measured using a glossiness tester. The test was repeated 10 times, and the results were averaged. The results are shown in Table 3.

[0094] Table 2

[0095]

[0096]

[0097] Table 3

[0098] Combing work (J) Glossiness(au) Example 1 <![CDATA[3.16×10 -2 ]]> 2.94 Example 2 <![CDATA[3.59×10 -2 ]]> 2.86 Example 3 <![CDATA[3.51×10 -2 ]]> 2.83 Comparative Example 1 <![CDATA[4.12×10 -2 ]]> 2.47 Comparative Example 2 <![CDATA[4.94×10 -2 ]]> 2.23 Comparative Example 3 <![CDATA[4.43×10 -2 ]]> 2.41 Comparative Example 4 <![CDATA[4.38×10 -2 ]]> 2.44 Comparative Example 5 <![CDATA[5.49×10 -2 ]]> 2.09 Comparative Example 6 <![CDATA[4.67×10 -2 ]]> 2.37 Comparative Example 7 <![CDATA[5.71×10 -2 ]]> 2.03 Comparative Example 8 <![CDATA[5.86×10 -2 ]]> 1.89 Comparative Example 9 <![CDATA[5.80×10 -2 ]]> 1.94 Comparative Example 10 <![CDATA[5.93×10 -2 ]]> 1.87 Comparative Example 11 <![CDATA[7.55×10 -2 ]]> 2.80

[0099] It can be seen that the increase rate of Young's modulus and combing work of the hair products obtained in Examples 1 to 3 are significantly lower than those in Comparative Examples 1 to 11, and the glossiness is significantly higher than that in Comparative Examples 1 to 10 and is equivalent to that in Comparative Example 11 using chemical hair dyes, indicating that the hair products containing the emblica extract of the present invention have better elasticity, combing properties and glossiness, and can also significantly reduce the sensitivity of dyed hair to ultraviolet rays, that is, can greatly reduce the damage to hair caused by dyeing.

[0100] In summary, the present invention finds that when the molecular weight of the emblica extract is 500-1000Da, it can be compounded with specific types of emulsifiers and thickeners, solubilizers and penetration enhancers, developers and other ingredients to obtain a hair product with better stability, which can not only make the dyed hair have better elasticity, combing properties and glossiness, but also reduce the sensitivity of the dyed hair to ultraviolet rays, indicating that it can greatly reduce the damage to hair caused by dyeing.

[0101] The above embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited to the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principles of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
