Description

Shampoo and preparation method thereof

Technical Field

The application relates to the field of washing and caring products, in particular to a shampoo and a preparation method thereof.

Background

Shampoo is a hair cleansing product which is most widely used, and is used for washing away grease, sweat stain, cells detached from the scalp, foreign dust, microorganisms, residues and bad smell of styling products, etc. which are secreted from human bodies and adhered to the scalp and hair, and keeping the scalp and hair clean and beautiful.

Most young and middle-aged people today suffer from hair loss. In the period of abnormal increase of sebaceous gland secretion, sebum is easy to accumulate at hair follicles, and the propagation of fungi is promoted, so that fungi can damage hair follicle cells; and a long-term deficiency in the supply of nutrients to the hair follicles, can lead to long-term dormancy and even necrosis of the hair follicles, resulting in an increase in the amount of hair loss. Shampoo on the market today has the main functions of cleaning and removing odor, and basically has no improvement on alopecia.

Characterization test:

1. test for alopecia ameliorating Effect

Test samples: examples 1-13, comparative examples 1-3 and the blank group, for a total of 17 test samples.

Test subjects: 57 Chinese males who were healthy at 18-40 years old, had no serious chronic wasting disease, had alopecia or seborrheic alopecia, had not used products and treatments with hair-growing efficacy within one month, and had not recently taken medicines and supplements were randomly selected as subjects. Each three subjects were tested against one test sample.

The test method comprises the following steps: the test period is 7 months and 1 day to 10 months and 1 day, and the total test duration is 3 months. The subject used the common shampoo on the first day to carry out the routine self-habit hair washing procedure, which is marked as (r), the water passing through the head of the hair washing process passes through the filter screen, the hair loss is trapped and passes through the water and the foam. After the hair is cleaned, the trapped hair is washed by clear water until no foam exists, and the hair is dried and loses hair. During the test, the subject washes his hair once every 2 days, and records the last washing as two, and then carries out the hair loss interception and records the hair loss amount. Calculating and recording the reduction rate (%) of the hair loss amount of the last hair washing and the first hair washing (the hair loss amount of the last hair washing-the hair loss amount of the first hair washing)/the hair loss amount of the first hair washing; the average of the rate of decrease in hair loss of the three subjects in each group of test samples was calculated.

And (3) test results: the results of the hair loss-improving effect test are shown in table 2.

TABLE 2 Hair loss improvement test results

And (3) data analysis: as can be seen from the data of table 2, the examples and comparative examples have hair loss improving effects with respect to the blank group. The order of the alopecia-improving effect gradually decreases is: examples 12-13, examples 8-11, examples 6-7, examples 2-5 and example 1, followed by comparative example 3, comparative examples 1-2.

Comparing example 1 and comparative examples 1 to 3, it can be seen that the combination of the black mulberry leaf extract, the canola oil and the emollient oil can improve the effect of hair loss. The reasons may be: the low erucic acid rapeseed oil contains a small amount of erucic acid, which can provide an acid environment for the black mulberry leaf extract, thereby promoting the dissolution and the function of active substances of the black mulberry leaf extract, greatly improving the utilization rate of the active substances and having quick effect; ensures that the hair follicle can keep healthy when grease is accumulated, and greatly reduces head acne and hair follicle inflammation. Meanwhile, the black mulberry leaf extract can provide nutrition for hair follicles, strengthen the hair follicles and reduce dormancy and necrosis of the hair follicles. In addition, the acidity of the canola oil can play a role in smoothing hair scales and smoothening hair.

Examples 2 to 5 the preparation method of the hair follicle-conditioning agent was improved based on example 1, and the hair loss-improving effect was more excellent. The reasons may be: coating the black mulberry leaf extract with emollient oil, and mixing with canola oil; when in use, the materials in the shampoo are uniformly mixed due to rubbing and foaming, and the black mulberry leaf extract is gradually in an acidic environment to release effective substances and take effect. Compared with the direct mixing, the result is worse than that of the previously mixed emollient oil, and the effective substances in the black mulberry leaf extract can be in an acidic environment for a long time, so that the action effect of the black mulberry leaf extract can be weakened. The acidic environment is favorable for dissolving out the effective substances in the black mulberry leaf extract, but the effect of the black mulberry leaf extract is weakened after being subjected to the acidic environment for a long time. Under the condition that the black mulberry leaf extract is coated by the emollient oil, the canola oil is gradually and fully mixed with the emollient oil, and the effective substances of the black mulberry leaf extract are slowly dissolved out.

Examples 6 to 7 further limit the use amount of the canola oil and the black mulberry leaf extract on the basis of example 3, and examples 8 to 11 limit the selection of the emollient oil on the basis of example 7, which slightly improve the hair loss improving effect. Examples 12 to 13 are based on example 11 and define the composition of the antimicrobial conditioner which, in combination with the hair follicle conditioner, gives a better hair loss-improving effect.

2. Comparative test subjects for hair loss-improving effect after storage: examples 1-13, comparative examples 1-3 and the blank group, for a total of 17 test samples.

Test subjects: the test subjects were the same lot as in test "1 and alopecia improvement effect test", and the test samples corresponding to each test subject were also the same as in test "1 and alopecia improvement effect test".

The test method comprises the following steps: parallel samples of the test specimen samples were prepared, the test specimen was filled in a bottle and unsealed for 4 months and 1 day, to 10 months and 1 day, for 6 months. After the test "1, alopecia improvement effect test" was completed, the subject used the test sample unsealed for 6 months and continued to use for 3 months. The final hair loss amount in test "1, hair loss improvement effect test" was taken as the initial hair loss amount and recorded as |, and during the test, the subjects washed their hair every 2 days, and the final hair loss amount was taken as the final hair loss amount, and the hair loss amount change rate (%) (initial hair loss amount-final hair loss amount)/initial hair loss amount was calculated and recorded.

And (3) test results: the hair loss-improving effect after storage is reported in table 3, comparing the test results.

TABLE 3 comparative test results record of hair loss improvement after storage

And (3) data analysis: as can be seen from the data in Table 3, the change rates of examples 10-13 were positive and the values were the largest, the change rates of examples 2-3 were positive and the values were smaller than those of examples 10-13, and the change rate values of example 1 were the smallest. Because the test time is 10-1 month, the baldness is easily caused by season change, or the change rate of the blank group is changed in a negative value within the allowable range of test error.

Due to the effect of the stabilizer, the effective substances of examples 10-13 can continue to act after long-term storage, further improving alopecia, which indicates that the stabilizer has the effect of stabilizing the effective components, and the reason may be that: gum arabic and lactic acid can be used as a stabilizer of raw materials of the ingredients on one hand to keep the stable effect of the raw materials; on the other hand, when in use, the lactic acid and the canola oil jointly promote the dissolution of the effective substances of the black mulberry leaf extract; the storage period is prolonged and the amount of hair loss is further reduced. During storage, the stabilizing agent can slow down the dissolution of the effective substances in the black mulberry leaf extract by the canola oil and/or reduce the weakening effect of the effective ingredients by the acidic environment.

In examples 2 to 9, the subjects who originally had a small amount of hair loss had substantially only a maintenance effect, and the hair loss effect could not be further improved; the results of further improvement were slightly observed in subjects who had originally had a large amount of hair loss. Indicating that the stability in examples 2-9 is less good than in examples 10-13.

The change rate of example 1 is small compared with that of example 2, which shows that the preparation method of the hair follicle conditioning agent can influence the action effect of the stabilizing agent. The skin moistening oil agent is coated outside the black mulberry leaf extract, so that the stabilizing effect of the effective substances or the stabilizing effect of the stabilizer can be further improved.

The present embodiment is only for explaining the present application, and it is not limited to the present application, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present application.
