Evaluation of use of the compositions prepared in test example two and comparative examples 1 to 9

In accordance with the first judgment mode of the test example, the related toxicology tests of the comparative examples 1 to 9 are carried out, and the test is washed by an acute eye irritation test (30 s), so that the test is non-irritating; through an acute skin irritation test, the result shows that the skin irritation is free; the result of the skin phototoxicity test shows that no skin phototoxicity is seen; the skin allergy test shows that no skin allergy is found.

Evaluation of use: according to the first evaluation method of the test example, 90 persons with 25-35 years old, healthy head skin without allergy or scars and without local systemic other diseases have certain scalp problems (such as excessive dandruff, excessive grease secretion, scalp itching sensitivity and the like), 45 men and 45 women are randomly divided into 9 groups, 5 men and 5 women in each group are respectively corresponding to one group of compositions in comparative examples 1-9, the compositions used are evaluated after two weeks every other day, in the use process, the subjects are required to keep the compositions on hair for 2-3 minutes according to normal hair washing habit, and then the hair can be washed out with water, and the evaluation indexes comprise cleaning effect, scalp comfort, dandruff improvement degree, carding effect and glossiness, and the specific evaluation results are shown in Table 6.

Table 6: the compositions prepared in comparative examples 1 to 9 were evaluated using the results of evaluation

As can be seen from the results of table 6, the compositions prepared in comparative examples 1 to 9 were significantly inferior to the hair care composition prepared in example 3 in terms of the evaluation, and the results of the evaluation in comparative example 1 revealed that the polygonum multiflorum extract had a significant effect of improving dandruff and nourishing scalp, and in addition, the conventional ginger washing and caring was able to improve the dandruff effect, but had a greater irritation to the scalp, so that the addition of the polygonum multiflorum extract significantly improved the defect; in addition, the hair care composition prepared by the invention can improve the permeation effect of active ingredients (namely polygonum multiflorum extract, aloe extract and ginger extract) by adding the methyl propylene glycol and the C12-14 secondary alkanol polyether-9 in the mass ratio of (1.2-2), and the use evaluation results of comparative examples 2-4 show that the C12-14 secondary alkanol polyether-9 has larger influence on the use effect of the hair care composition, the moisturizing effect of the hair care composition is reduced due to the lack of the components, the cleaning effect is also reduced, scalp oil is discharged quickly after use, the maintenance effect is poor, and the hair follicle cleaning effect is reduced; in a third aspect, the invention adopts the PEG-8 ester of C12-20 acid and the C12-15 alkanol polyether-2 phosphate with the mass ratio of 1 (0.5-3) to obtain the hair care composition with good stability, and the results of comparative examples 5-9 in Table 6 show that the PEG-8 ester of C12-20 acid and the C12-15 alkanol polyether-2 phosphate have obvious improvement effect on the cleaning effect of the composition within the range of the ratio, can maintain better cleaning effect and improve the hair quality effect to a certain extent; the hair care compositions of the present invention exhibit optimum efficacy at a pH in the range of 5.5 to 5.8.

Test example III, effect of composition on scalp lipid and moisture content

The compositions prepared in example 3 and comparative examples 1 to 9 were tested for scalp grease and moisture content as follows:

(1) Scalp grease test

According to the principle of a grease testing photometer, an MB560 scalp grease tester is adopted for testing, two ends of a tape strip are folded and fixed on a grease probe, the probe is pressed and contacted with a scalp to-be-tested part for 30 seconds, the grease on the scalp changes the transparency of the testing tape, a light transmittance distribution curve on the tape can be obtained through testing by a photoelectric tube in the instrument, the peak value of the light transmittance distribution curve represents the content of the grease on the scalp, and 3 parallel data are taken to obtain an average value.

(2) Scalp moisture content test

The scalp moisture loss rate is measured by pressing a probe of the tester on the less hair and scalp at the temple of the volunteer through a Vaponter percutaneous moisture loss tester for 30 seconds, and 3 parallel data are taken to obtain an average value.

The experimental process comprises the following steps: the composition is selected to be used for 25-35 years old, the skin of the head is healthy and has no allergy or scars and no local systemic other diseases, 55 people with scalp problems (such as excessive dandruff, excessive grease secretion, scalp itching sensitivity and the like) are randomly divided into 11 groups of 3 men and 2 women, each group corresponds to one group of compositions in the embodiment 3 and the comparative examples 1-10, the composition is required to be used once every day, during the use process, the subject is required to keep the composition on the hair for 2-3 minutes and perform proper massage, then the scalp can be washed cleanly by water, the scalp can be cleaned before the use (common shampoo washing), after the use for one week and two weeks, the test time is immediately after the hair is cleaned, the volunteer needs to sit still for 30 minutes in a room with the indoor temperature of 20-22 ℃ and the humidity of 55% +/-5%, the test sites cannot be exposed to water and drink, the test sites are placed in a test state, the test time is kept, the test time is 0h and the scalp is 6h, and the scalp secretion amount of the scalp is calculated after the scalp is lost after the scalp is cleaned.

The specific evaluation results are shown in Table 7.

Table 7: effect of the composition on scalp oil and moisture content

As can be seen from the results of table 7, the hair care compositions of the present invention have good effects in controlling oil and retaining water compared to the compositions prepared in comparative examples 1 to 9, the scalp oil secretion amount is reduced by 3.07% and 1.87% respectively within 6 hours after one week and two weeks using the hair care composition prepared in example 3, the scalp moisture loss amount is reduced by 4.22% and 6.94% respectively, and the scalp oil secretion amount is reduced by about 1.71% to 2.76% and 1.07% to 1.62% respectively within 6 hours after one week and two weeks using the compositions of comparative examples 1 to 9, and the scalp moisture loss amount is reduced by about 2.26% to 4.01% and 1.55% to 2.59% respectively, thereby it can be seen that the hair care composition of the present invention has remarkable effects of inhibiting scalp oil secretion and retaining scalp moisturization.
