Description

Technical Field

[0001] The present invention belongs to the field of daily-use cosmetics, and particularly relates to a composition with oil control and fluffing effects and its application. Background Art

[0002] With the acceleration of the pace of life, bad habits in modern people's diet such as eating greasy and spicy foods, and bad lifestyles such as staying up late are likely to stimulate the secretion of sebum by the scalp sebaceous glands. As more and more consumers have problems such as excessive scalp sebum secretion, dandruff, and scalp sensitivity, the demand for the efficacy of hair care products by consumers is gradually increasing. Among them, the imbalance of scalp sebum secretion has led to a more urgent demand for oil control and fluffing effects of hair care products by more consumers.

[0003] In addition, when there is too much oil on the scalp and inappropriate cleansing products are used to remove oil excessively, the cutin layer is damaged and the scalp barrier will also be damaged; furthermore, the loss of scalp moisture is serious, and the scalp's self-defense system will secrete too much sebum in an attempt to prevent water loss. However, this excessive sebum has the opposite effect, damaging the skin barrier and further causing water loss, falling into a vicious cycle of getting drier and oilier, and oilier and drier. Therefore, scalp oil control not only needs to inhibit excessive sebum secretion, but also needs to do a good job in moisturizing and protecting the scalp barrier.

[0004] CN108670914A discloses a shampoo with oil control effect. This shampoo with oil control effect contains extracts of Eclipta prostrata, Paeonia lactiflora, Camellia japonica, Sophora flavescens, Dracaena cochinchinensis, Trigonella foenum-graecum seeds, and Cynara cardunculus leaves in a specific ratio. By controlling the dosage of each component, each component can synergistically enhance the effect while fully exerting its basic effect, playing a role in oil control and nourishing hair roots. This shampoo has excellent effects of oil control and nourishing hair roots, and is suitable for people with oily hair or poor hair quality.

[0005] CN118948710A discloses a highly efficient oil control, anti-hair loss and repair shampoo, which includes 1-5 parts of coconut oil diethanolamide, 20-30 parts of sodium lauryl polyether sulfate, 20-50 parts of lauryl betaine, 10-40 parts of ethylhexylglycerin, 8-20 parts of plant extraction composition, 4-18 parts of anti-inflammatory composition, 2-6 parts of hyaluronic acid, 1-5 parts of β-glucan, 2-7 parts of tremella polysaccharide, 4-10 parts of brown algae extract, 2-7 parts of retinol palmitate, 2-6 parts of squalane, 4-8 parts of hydrogenated lecithin, and 5-40 parts of deionized water by weight. The preparation process of the present invention is simple, and the prepared shampoo has the effects of oil control and anti-hair loss, can improve the growth vitality of hair follicle cells, promote hair regeneration, enhance the metabolic function of hair follicles, and at the same time can balance oil control from multiple dimensions to further improve the oil control effect of the shampoo. However, the above shampoo has complex ingredients and does not have the dual effects of simultaneously improving oil control and fluffing.

[0006] Therefore, how to develop a composition with long-lasting oil control, fluffing effects and mildness and no irritation has become a technical problem to be solved urgently at present. Summary of the Invention

[0007] Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide a composition with oil control and fluffing effects and its application. The composition has excellent long-lasting oil control and fluffing effects, and is mild and non-irritating.

[0138] Application Examples 4 - 9 each provide a shampoo with oil control and fluffing effects. The differences from Application Example 1 are only that the composition with oil control and fluffing effects in Example 1 in the formulation is successively replaced with the composition with oil control and fluffing effects in Examples 4 - 9 of equal mass; the other components in the formulation remain unchanged; the preparation method refers to Application Example 1.

[0139] Comparative Application Examples 1 - 4

[0140] Comparative Application Examples 1 - 4 each provide a shampoo with oil control and fluffing effects. The differences from Application Example 1 are only that the composition with oil control and fluffing effects in Example 1 in the formulation is successively replaced with the composition with oil control and fluffing effects in Comparative Examples 1 - 4 of equal mass; the other components in the formulation remain unchanged; the preparation method refers to Application Example 1.

[0141] Test Example 1

[0142] Oil control and fluffing effect test

[0143] (1) Test method:

[0144] Select 130 subjects aged 20 - 55 with oily scalps and scalp oil content > 350, and divide them into 13 groups evenly, with 10 people in each group.

[0145] (1.1) Before using the sample (T0):

[0146] Subjects should not wash their hair 48 hours before arrival. Sit quietly in a laboratory at a temperature of 21 ± 1°C and a humidity of 50 ± 10% RH for 30 minutes, and use the scalp oil tester Meibometer MB560 to measure the skin oil content of the subjects.

[0147] (1.2) Using the sample:

[0148] After wetting the hair, take an appropriate amount of the shampoo samples of each application example and comparative application example into the palm, lather it and apply it to the hair, gently massage the hair and scalp with the fingertips, and finally rinse it with clean water.

[0149] (1.3) Measuring the oil content after using the sample (T24 h and T48 h):

[0150] 24 hours and 48 hours after using the sample, let the subjects sit quietly in a laboratory at a temperature of 21 ± 1°C and a humidity of 50 ± 10% RH for 30 minutes respectively, and use the scalp oil tester Meibometer MB560 to measure the scalp oil content; the lower the measured value, the lower the scalp oil content.

[0151] Calculate the change rate of scalp oil content of each test sample and the average change rate of scalp oil content of the subjects:

[0152] Change rate of scalp oil content = [(scalp oil value after use) - (scalp oil value before use)] / scalp oil value before use × 100%;

[0153] The average change rate of scalp oil content of the subjects is the average value of the change rates of scalp oil content of each subject.

[0154] (1.4) Measuring the fluffiness after using the sample (T24 h and T48 h):

[0155] 24 hours and 48 hours after using the sample, let the subjects sit quietly in a laboratory at a temperature of 21 ± 1°C and a humidity of 50 ± 10% RH for 30 minutes respectively, and score the fluffiness after using each sample according to the following scoring system.

[0156] Scoring system: The score ranges from 1 to 10. 1 point means very flat, and 10 points means very fluffy. After scoring, take the average value of each sample. The higher the score, the better the fluffing effect of the shampoo.

[0157] (2) Test results:

[0158] The results of the change rate of the average scalp oil content and the fluffiness score of the subjects after using each sample for 24 h and 48 h are shown in Table 5. It can be seen that the shampoo involved in the present invention has long-lasting oil control and fluffiness effects, and still has a low oil content and excellent fluffiness after using the shampoo for 48 h.

[0159] From the data comparison between Application Example 1 and Comparative Application Examples 1-4, it can be seen that when any one of pueraria root extract, paeonol, pyridoxine hydrochloride or matrine is missing in the composition, the oil control and fluffiness effects of the composition all decrease to varying degrees, indicating that pueraria root extract, paeonol, pyridoxine hydrochloride and matrine have significant synergistic effects in terms of oil control and fluffiness.

[0160] From the data comparison between Application Example 1 and Application Example 4, it can be seen that the pueraria root extract prepared by the microfluidic extraction method can better exert the synergistic effect with paeonol, pyridoxine hydrochloride and matrine, and better improve the long-lasting oil control and fluffiness effects of the composition.

[0161] From the data comparison between Application Example 1 and Application Examples 5-7, it can be seen that in the preparation process of pueraria root extract, the combination of tannase, α-rhamnosidase and isoamylase has a certain synergistic effect in the enzymatic hydrolysis effect. Enzymatic hydrolysis of the crude pueraria root extract with this complex enzyme can further improve the oil control and fluffiness effects of the prepared pueraria root extract.

[0162] From the data comparison between Application Example 1 and Application Examples 8-9, it can be seen that based on the synergistic effect of each component in the composition in terms of oil control and fluffiness, when the composition includes 0.5-5 parts of pueraria root extract, 0.5-5 parts of paeonol, 5-50 parts of pyridoxine hydrochloride and 1-10 parts of matrine by mass, the overall oil control and fluffiness performance of the composition can be further improved.

[0166] Test Example 2

[0167] Skin irritation evaluation

[0168] In this test example, the skin irritation of the samples of each application example and comparative application example was investigated and verified by the chicken embryo chorioallantoic membrane blood vessel test. Utilizing the characteristics of the CAM (i.e., the middle chorioallantoic membrane of the fertilized chicken embryo at the embryonic age of 10-14 days) with complete, obvious and transparent blood vessels, the reaction of the human skin to irritation was objectively reflected.

[0169] Sixty-five CAM blood vessels were selected and randomly divided into 13 groups, with 5 in each group. They were respectively contacted with 13 groups of samples of Application Examples 1-9 and Comparative Application Examples 1-4 diluted 100 times. After acting for 5 minutes, the damage of CAM blood vessels was observed, and the degree of damage was scored. The larger the score, the more serious the damage. The judgment criteria and the average score results of each group are shown in Table 6 and Table 7 respectively.

[0175] It can be seen from the data in Table 7 that the shampoo with oil control and fluffing effects involved in the present invention will not cause obvious damage to CAM blood vessels, indicating that the shampoo involved in the present invention is mild and has extremely low irritation.
