Description

Technical Field

[0001] The invention belongs to the technical field of cosmetics, and particularly relates to a fluffy oil-control composition, a preparation method and application of the composition in shampoo products. Background Art

[0002] Sebum emulsification forms a sebum membrane that protects the scalp's health. However, excessive sebum secretion provides a rich nutrient source for microbial colonization. Seborrhea is excessive sebum secretion caused by hyperfunction of the sebaceous glands. This condition manifests as a greasy, oily scalp and hair, along with increased dandruff. Furthermore, if the head is not cleaned promptly, foreign pollutants and fine dust will adhere to the scalp and hair, further irritating the scalp and leading to increased scalp lipid secretion. This is often accompanied by problems such as dandruff and itching, and can even develop into seborrheic alopecia over time, seriously impacting modern people's quality of life.

[0003] At present, there are many anti-dandruff, oil-control and anti-itching products on the market, but these products often use chemically synthesized ingredients, such as antibacterial agents, anti-dandruff agents, etc. Although these ingredients can improve the scalp condition to a certain extent, long-term use may cause scalp sensitivity, dryness, recurrent dandruff and other problems, and the chemical ingredients may pose potential risks to human health.

[0004] In contrast, plant extracts have gradually become a research hotspot in the field of toiletries due to their natural, mild and non-irritating properties. Plant extracts are rich in a variety of active ingredients, such as alkaloids, flavonoids, polyphenols,

[0005] Terpenes, etc. These ingredients have significant effects in controlling oil, relieving itching and removing dandruff.

[0006] For example, Chinese patent CN113876666A discloses an anti-dandruff and anti-itching shampoo and its preparation method. The anti-dandruff and anti-itching shampoo is made from the following raw materials in percentage by weight: 0.2%-0.8% of nasturtium root extract, 0.1%-0.5% of Sophora flavescens root extract, 0.1%-0.5% of Albizia julibrissin bark extract, 0.8%-1.2% of an anti-dandruff agent, 3%-5% of a hair conditioner, 3%-5% of a surfactant, 0.02%-0.05% of an antistatic agent, 8%-12% of a foaming agent, 2%-4% of a moisturizing agent, 0.1%-0.4% of a viscosity modifier, 0.2%-0.4% of phenoxyethanol, 0.2%-0.3% of ethylhexylglycerin, 0.1%-0.2% of sodium benzoate, 0.2%-0.4% of a fragrance, and the balance of deionized water. The anti-dandruff and anti-itching shampoo described in this invention has the effects of oil control, anti-itching, long-lasting dandruff removal, etc. By using natural plant active ingredients and mild surfactants, it can reduce irritation and is safe and reliable to use.

[0007] For example, Chinese patent CN113842342A discloses a botanical anti-dandruff and antipruritic agent, its preparation method, and use. The active ingredients of this botanical anti-dandruff and antipruritic agent include only 100-150 parts by weight of Bletilla striata extract, 15-25 parts by weight of Centella asiatica extract, 8-12 parts by weight of Gentiana scabra extract, and 8-12 parts by weight of loquat leaf extract. This botanical anti-dandruff and antipruritic agent, through the synergistic action of its components, exhibits highly effective antibacterial and anti-inflammatory effects, achieving the purpose of removing dandruff and alleviating itching. It also boasts the advantages of being natural, mild, non-irritating, and highly safe.

[0008] However, existing shampoo products pursue higher oil control and anti-itching effects, which lead to problems such as dry skin after long-term use. Therefore, there is an urgent need for a composition that takes into account oil control, anti-itching, anti-dandruff and moisturizing, and uses it in shampoo products to enable the shampoo products to have moisturizing, oil control, anti-itching and anti-dandruff effects. Summary of the Invention

[0056] Effect detection:

[0057] 1. 5α-reductase inhibition test

[0058] Seborrhea is a disorder of sebaceous gland function, resulting in excessive sebum secretion, leading to an accumulation of oil in the skin and hair, resulting in a greasy, shiny appearance and the appearance of scales. Sex hormone imbalance, primarily due to increased androgen levels, can lead to increased sebaceous gland secretion. Androgens, androgen receptors, and the activity of androgen-metabolizing enzymes can all influence oil secretion. There are two types of the androgen-metabolizing enzyme 5α-reductase: type I is found in the liver and sebaceous glands, while type II is primarily found in gonadal tissue and hair follicles in the scalp and beard area. The androgen testosterone is converted to dihydrotestosterone by 5α-reductase, which binds to the androgen receptor five times more efficiently than testosterone. Dihydrotestosterone promotes cellular processes, inducing increased sebum secretion in the sebaceous glands. 5α-reductase activity can influence oil secretion in different parts of the body. Based on this principle, the oil-control effect of the sample is preliminarily judged by the degree of inhibition of the experimental sample on the activity of 5α-reductase. The higher the inhibition rate of 5α-reductase, the stronger the oil-control effect of the sample, and vice versa.

[0059] The fluffy oil-control compositions in the Examples and Comparative Examples were each prepared into samples with a mass concentration of 15%. Testosterone was selected as a substrate, and finasteride was used as a positive control. The results were analyzed using high-performance liquid chromatography to measure the change in testosterone concentration before and after the reaction. The inhibition rate of the oil-control and fluffy compositions on 5α-reductase was calculated based on this. The results are shown in Table 3.

[0060] Table 3

[0061]

[0062] According to the test results in Table 3 above, the fluffy oil-control compositions prepared in Examples 1-4 of the present invention have better effects in inhibiting 5α-reductase.

[0063] In Example 2, by controlling the mass ratio of the plant extract to lauroyl alanine to 8:2 and the mass ratio of the rice husk extract, sage extract, ginkgo leaf extract and rosemary extract to 4:2:3:1, the obtained fluffy oil-control composition has the highest inhibitory effect on 5α-reductase.

[0064] In Comparative Example 1, replacing the sage extract with the rice hull extract reduced the inhibitory effect of the fluffy oil-control composition on 5α-reductase to 52.1%.

[0065] In Comparative Example 2, replacing the Ginkgo biloba extract with the Rosemary extract reduced the inhibitory effect of the fluffy oil-control composition on 5α-reductase to 50.7%.

[0066] In Comparative Example 3, changing the mass ratio of rice husk extract, sage extract, ginkgo leaf extract and rosemary extract to 1:4:1:4 will reduce the inhibitory effect of the fluffy oil-control composition on 5α-reductase to 55.9%.

[0067] In Comparative Example 4, replacing the Ginkgo biloba leaf extract with the Albizia julibrissin bark extract reduced the inhibitory effect of the fluffy oil-control composition on 5α-reductase to 53.6%.

[0068] This indicates that only by using the components disclosed in the present invention in a specific ratio can a better effect of inhibiting 5α-reductase be achieved.

[0069] 2. Malassezia furfur inhibition test

[0070] Malassezia furfur can cause oily hair. On the one hand, when Malassezia reproduces on the scalp, it stimulates the sebaceous glands to secrete more sebum, resulting in greasy hair. On the other hand, when Malassezia grows on the scalp, it destroys the barrier function of the scalp, making the scalp susceptible to infection by other bacteria and fungi, further aggravating the symptoms of oily scalp. Based on this, the degree of inhibition of the experimental sample on Malassezia furfur is used to preliminarily judge the oil-control effect of the sample. The higher the inhibition rate on Malassezia furfur, the stronger the oil-control effect of the sample, and vice versa.

[0071] Test strain: Malassezia furfur (ATCC44344).

[0072] Culture medium: Pityrosporum culture medium.

[0073] Test method: According to QB / T2738-2012 "Evaluation method for antibacterial and antimicrobial effects of daily chemical products", the fluffy oil control composition in the embodiment and the comparative example were respectively prepared into samples with a mass concentration of 15% for antibacterial effect evaluation. The number of viable bacteria was 3.0×10 4 CFU / mL, the test substance was exposed for 10 min. The antibacterial results are shown in Table 4 below.

[0074] Table 4

[0075]

[0076] According to the test results in Table 4 above, the fluffy oil-control compositions prepared in Examples 1-4 of the present invention have better effects in inhibiting Malassezia furfur.

[0077] In Example 2, by controlling the mass ratio of the plant extract to lauroyl alanine to 8:2 and the mass ratio of the rice husk extract, sage extract, ginkgo leaf extract and rosemary extract to 4:2:3:1, the obtained fluffy oil-control composition has the highest inhibitory effect on Malassezia furfur, which can reach more than 95%.

[0078] In Comparative Example 1, replacing the sage extract with the rice hull extract will reduce the inhibitory effect of the fluffy oil-control composition on Malassezia furfur to 86.4%.

[0079] In Comparative Example 2, replacing the Ginkgo biloba extract with the rosemary extract reduces the inhibitory effect of the fluffy oil-control composition on Malassezia furfur to 85.2%.

[0080] In Comparative Example 3, changing the mass ratio of rice husk extract, sage extract, ginkgo leaf extract and rosemary extract to 1:4:1:4 will reduce the inhibitory effect of the fluffy oil-control composition on Malassezia furfur to 88.4%.

[0081] In Comparative Example 4, replacing the Ginkgo biloba leaf extract with the Albizia julibrissin bark extract reduced the inhibitory effect of the fluffy oil-control composition on Malassezia furfur to 85.3%.

[0082] This shows that only by using the components disclosed in the present invention in a specific ratio can a better effect of inhibiting Malassezia furfur be achieved.
