The composition of the shampoo base was the same as that of example 4.
Comparative example 2 shampoo base
This comparative example provides a shampoo base having the same formulation as the shampoo base of example 4.
Experimental example Hair repair function test of Tricholoma matsutake Strain TriMatT35 fermented product
The shampoos of example 4 and comparative example 1 and the shampoo base of comparative example 2 were tested for hair restoration function, and the test methods and test results were as follows:
1. experiment for repairing damaged hair external hair scale damage effect by shampoo
Selecting healthy hair of a volunteer, washing with a sodium dodecyl sulfate solution, rinsing, and naturally drying for later use. Taking 4 parts of original hair, 10g of each part, soaking the original hair for 1h at 30 ℃ by using 0.5g/L NaOH, then taking out the original hair, rinsing the original hair to be neutral, and naturally airing the original hair to prepare damaged hair.
The damaged hair was subjected to a washing treatment using the shampoos of example 4 and comparative example 1 and the shampoo base of comparative example 2, respectively, in an amount of 0.5g for 3min, washed with clean water, and naturally dried.
The hair tresses which are not treated (blank sample) and are washed and treated by shampoo are respectively soaked in 0.2mol/L copper sulfate solution for 15min, and then the adsorption quantity of the hair to copper ions is tested.
TABLE 3 copper ion adsorption amount
Note: p <0.05, P <0.01, P <0.001vs. blank.
When the hair is damaged, the hair is negatively charged to adsorb copper ions, and the damage degree of the hair can be represented by measuring the amount of the copper ions adsorbed by the hair. The more damaged the hair, the more copper ions are adsorbed. As can be seen from table 3, compared with the blank sample, the adsorption amount of copper ions of the hair treated by the shampoo was significantly reduced, while compared with the shampoo containing the tricholoma matsutake strain T35 fermented product, the adsorption amount of copper ions of the hair treated by the shampoo containing the tricholoma matlt 35 fermented product was significantly reduced, which indicates that the tricholoma matsutake strain trimat 35 fermented product has a more significant repairing effect on the damage of the hair scales outside the hair.
2. Experiment for repairing damaged hair by shampoo in hydrophilic and lipophilic properties
Selecting 30 volunteers who are subjected to over-dyeing and ironing within three months, testing the hair contact angle (68-72 degrees for dry hair and 66-70 degrees for wet hair) of each volunteer, randomly dividing the hair into 3 groups, collecting the hair of each volunteer as a blank group, respectively cleaning the damaged hair by using the shampoos of example 4 and comparative example 1 and the shampoo of comparative example 2, using the shampoo water for 3 times every week, collecting the hair of the volunteer once every week, after the experiment of 3 weeks is finished, inserting the hair of each group into water under the two states of dry hair and wet hair by adopting a Wilhelmy balance method, calculating the contact angle of the water on the hair surface according to the force, and obtaining the result shown in Table 4.
TABLE 4 Hair contact Angle
Note: p <0.05, P <0.01, P <0.001vs. blank.
The damage degree of hair is directly related to the hydrophilic and hydrophobic properties of the hair surface, and the larger the damage degree of hair is, the stronger the hydrophilic property is. After the liquid spreads on the solid surface, the solid/liquid interface passes through the angle from the inside of the liquid to the gas/liquid interface, which is called the contact angle. The smaller the contact angle of water on the hair surface, the easier spreading and the stronger hydrophilicity. As shown in table 4, compared with the hair dyed and ironed (blank group), the hair using the shampoo of example 4 has a significantly increased contact angle and a statistical significance (P <0.05), which indicates that the tricholoma matsutake strain trimat 35 leavening can significantly repair the hair damage and restore the lipophilicity of the hair.
3. Effect of shampoo restoration on hair combing
The effect of the shampoo restoration of example 4 on the hair combing performance was analyzed by the following specific method:
30 volunteers who were subjected to over-dyeing and ironing within three months were selected, randomly divided into 3 groups of 10 persons each, and hair of each volunteer was collected before the start of the test and left, and each group of volunteers were washed with the shampoos of example 4 and comparative example 1 and the shampoo base of comparative example 2, respectively, used for 1 week, once every other day, and the hair of the volunteers was collected after the end of the test.
The collected hair was rinsed with tap water, the towel was wiped off the excess water until the hair strands did not drip, combed smoothly with a comb, and the wet combing property was tested with a tensile tester. The test results are shown in fig. 2.
Then, the hair is blown to be half-dry at a position 20cm away from the hair bundle by a blower, combed smoothly by a comb, naturally dried, and the combing property of the dried hair is tested by a universal tension tester. The test results are shown in fig. 3.
The results showed that the shampoo of example 4 was significantly superior in the effect on the combing property (wet combing property and dry combing property) of hair to the shampoo containing the fermented product of tricholoma matsutake strain T35 (comparative example 1) and the shampoo base (comparative example 2).
4. Shampoo repairing, dyeing and ironing damaged hair effect experiment
In order to verify the effect of the shampoo in example 4 on repairing, dyeing and perming damaged hair, 30 volunteers aged 25-60 years, dyed and permed hair within one year and having certain damage to hair during dyeing and perming are randomly divided into 3 groups, 10 people in each group are respectively provided with the shampoo in example 4, the shampoo in comparative example 1 and the shampoo matrix in comparative example 2, the using time is 2 months, the using frequency is once every two days, and the effects of the shampoo on repairing the internal structure of hair and strengthening hair are examined. The volunteers measured the maximum force and work of breaking of the hair before the start of the experiment, and 2 months after shampoo application, the maximum force and work of breaking of the hair were measured, and the change in hair strength was compared. The hair strength was tested using a Diastron tensiometer.
TABLE 5 Hair breaking Strength Change
As shown in table 5, the maximum breaking force and breaking work of the hair were significantly increased after using the shampoo of example 4 compared to before use, indicating that the tricholoma matsutake strain trimat 35 fermented product can significantly repair the internal structure of the hair and improve the hair strength.
