Description

Shampoo with dandruff removing, itching relieving and oil control effects and preparation method thereof

Technical Field

The invention belongs to the technical field of cosmetics, and particularly relates to a shampoo with effects of removing dandruff, relieving itching and controlling oil and a preparation method thereof.

Background

Dandruff is a common disease of the scalp, clinically manifested by excessive fine, grey, dry or slightly greasy pieces of pityrosporum which are on the scalp or hair, with itching, usually the process of desquamation of dead cells of the skin is manifested by separate clusters or flakes which are invisible to the naked eye, whereas in dandruff patients they are manifested by a continuous, coherent aggregation, forming small fragments which are visible to the naked eye, and the only or typical symptom of certain skin diseases such as seborrheic dermatitis, psoriasis and pityriasis rosea is desquamation of the scalp. Dandruff can also occur in inflammatory skin diseases such as allergic dermatitis, discoid lupus erythematosus, lichen dermalis of the lichen type, and tinea capitis. Dandruff, pityriasis capitis and seborrheic dermatitis of the scalp are not strictly defined conceptually, and dandruff is generally considered to be mild non-inflammatory seborrheic dermatitis.

Long-term research shows that the colonization of malassezia is one of the important causes of dandruff; in addition, dandruff is also related to the obvious reduction of the levels of free fatty acid, cholesterol and ceramide in the horny layer, so that the water barrier of the scalp is damaged, the hydration of the horny layer is reduced, the volume and the area of the horny layer are reduced, and the horny layer cracks to form scale, therefore, the healthy microecology of the scalp can be maintained by adjusting the microecological balance of the scalp, the bacterial infection of the scalp is reduced, the effect of resisting the bacterial invasion of the scalp barrier is enhanced, the scalp is further degraded to contain more grease, and the seborrheic dermatitis is improved.

For example, Chinese patent application 201910582207.7 discloses a allergy-relieving and nourishing shampoo and a preparation method thereof. The shampoo is prepared from the following raw materials in parts by weight: 1-3% of sea buckthorn oil, 1-3% of perilla oil, 20-40% of black tea rose ferment, 1-2% of whey protein hydrolysate, 0.01-0.05% of rose essential oil, 3-5% of L-arginine, 6-9% of sucrose ester, 10-15% of potassium myristate, 2-6% of salicylic acid, 3-5% of Chinese honeylocust fruit powder, 0.01-0.5% of preservative and the balance of deionized water. The application achieves the effect of removing dandruff and controlling oil by adding salicylic acid as an effective component into shampoo, but the salicylic acid is not designed for resisting fungi, does not have obvious antifungal effect, has poor dandruff removing effect and high irritation, and is easy to damage the skin.

Further as disclosed in chinese patent application 202110766391.8, an anti-dandruff oil control composition, and its preparation method and application, comprises an anti-dandruff component selected from one or more of sulfur, colloidal sulfur, and piroctone olamine salt, or/and an oil control component selected from one or more of capryloyl glycine, undecylenoyl glycine, and zinc gluconate. The anti-dandruff oil-control composition comprises an anti-dandruff component or/and an oil-control component, and although the anti-dandruff component contains sulfur, the sulfur can cause certain damage to hair quality and scalp although the anti-dandruff component has a good bactericidal effect.

Therefore, the shampoo which has good anti-dandruff effect, strong oil control capability, mildness and no irritation and the preparation method thereof need to be developed.

Step 3: after culturing for 4 days at 30 ℃, counting colonies and calculating the bacteriostasis rate.

The test results are shown in Table 1 below

TABLE 1

According to the detection data in the table 1, the shampoos prepared in the examples 1 to 3 and the comparative examples 1 to 2 and 5 of the present invention have good antibacterial performance, but the shampoo prepared in the example 1 has the best antibacterial performance, and the content and the mass ratio of the components are controlled, particularly the mass ratio of the POLYGONUM HYDROPIPER (POLYGONUM HYDROPIPER) extract to the antibacterial agent is 3:13, so that the obtained shampoo has the antibacterial performance fully exerted, and the antibacterial effect is improved.

2. Oil control efficacy evaluation experiment

(1) Principle of experiment

The skin was tested for oil content using the oil tester SebumeterSM 815. Based on the principle of a photometer, a special extinction adhesive tape with the thickness of 0.1mm can be changed into a semitransparent adhesive tape after absorbing grease on human skin, the light transmission quantity of the semitransparent adhesive tape can be changed, the more grease is absorbed, the greater the light transmission quantity is, and the content of the grease on the skin can be measured.

(2) Test method

In a shampoo shop in a certain market, 60 oily scalp subjects were randomly searched, 10 subjects per group. The subjects were stood still in a laboratory at a temperature of 22. + -. 3 ℃ and a relative humidity of 50. + -.5% for 30 minutes, and the skin oil content of the left and right forehead was measured with an oil tester SebumetersM815, respectively, as data D0, and the shampoo samples prepared in application examples 1-3 and comparative examples 1-2, 4 were distributed to each subject, shampooed once a day for 28 days, and the skin oil content was measured in the laboratory at constant temperature on days 14 and 28, respectively, as data D14 and D28. Respectively calculating the oil content change rate of D14 and D28 according to the following formula:

the change rate of the oil content { (oil content after use of sample-oil content before use of sample)/oil content before use of sample } × 100%, and the detection results are shown in table 2 below.

TABLE 2 Rate of change of oil content of shampoos prepared in examples 1-3 and comparative examples 1-2, 4
