Description

Technical Field

[0001] This invention relates to the field of shampoo products, and in particular to a plant extract complex with oil-controlling and dandruff-removing effects, its preparation method, and its application. Background Technology

[0002] Shampoo is a product used to clean hair. Its main purpose is to remove dust, oil and other impurities from the hair, restoring it to a clean state.

[0003] However, because the scalp continuously secretes oil, which adheres to the hair and becomes nutrients for bacteria, leading to an increase in bacterial secretions, the hair will become "unclean" again after a period of time after washing, seriously affecting people's energy and spirit. Therefore, shampoos that focus on oil control and dandruff removal have become one of the mainstream products.

[0004] Existing oil-controlling and dandruff-removing shampoos primarily achieve their effects by adding ingredients with oil-controlling and antibacterial properties. These ingredients reduce sebum secretion and kill Malassezia fungi. However, dandruff can also be caused by excessive shedding of scalp keratinocytes in addition to bacterial secretions. When the scalp is in an allergic state, irritation can trigger a stress response, accelerating the shedding of keratinocytes and leading to dandruff. Dryness can also cause accelerated keratinocyte shedding, resulting in dandruff. Unlike regular skincare products, shampoos do not remain on the skin's surface for extended periods. Therefore, while moisturizing ingredients are added to shampoos, their moisturizing effect is limited because they cannot form a protective film on the scalp. Consequently, the dandruff-removing effect of existing shampoos often fails to meet consumer needs, indicating room for improvement. Summary of the Invention

[0005] In order to enable shampoos to have good oil control and antibacterial effects, as well as good soothing and skin barrier repair effects, thereby improving the long-lasting dandruff removal effect, this application provides a plant extract complex with oil control and dandruff removal effects, its preparation method and application.

[0006] In the first aspect, this application provides a plant extract complex with oil-controlling and dandruff-removing effects, employing the following technical solution: A plant extract complex with oil-controlling and dandruff-reducing effects comprises the following components in parts by weight: Solvent: 74.6-81.4 parts; Oil-controlling and dandruff-removing composition: 17.8-24.2 parts; Preservative: 0.8-1.2 parts; The oil-controlling and dandruff-removing composition is a compound of succinic acid, Coptis chinensis root extract, Sophora flavescens root extract, Polygonum cuspidatum root extract, Zanthoxylum bungeanum fruit extract, and Viola yedoensis extract.

[0007] By employing the above-mentioned technical solution, and through the compounding of succinic acid, Coptis chinensis root extract, Sophora flavescens root extract, Polygonum cuspidatum root extract, Zanthoxylum bungeanum fruit extract, and Viola yedoensis extract, the synergistic effect of these active ingredients achieves excellent oil control, effectively inhibiting scalp sebum secretion for a long time. Simultaneously, it possesses strong antibacterial properties, exhibiting a high inhibition rate against Malassezia, significantly reducing the excessive secretions caused by Malassezia and thus reducing dandruff. Furthermore, it has a good soothing effect, quickly relieving scalp discomfort, repairing allergic reactions, and making the scalp less prone to stress responses due to irritation, thus reducing the occurrence of keratosis pilaris caused by stress. This product addresses the issue of dandruff caused by abnormal shedding of keratinocytes. Furthermore, it effectively promotes skin barrier repair, eliminating the need for a moisturizing film on the scalp. After the scalp's skin barrier is repaired, its own water-locking ability is significantly enhanced, preventing dryness and reducing the likelihood of abnormal keratinocyte shedding and dandruff formation due to dryness. Through this multi-dimensional combination of effects, shampoos containing plant extract complexes with oil-controlling and dandruff-removing properties achieve long-lasting oil control and dandruff-removing effects, keeping hair clean for extended periods and effectively meeting consumer needs.

[0097] Test sample: 0.3g of plant extract complex with oil-controlling and dandruff-removing effects, 99.7g of deionized water, mixed evenly.

[0098] Experiment 3 Several volunteers were recruited. The volunteers had symptoms of itchy scalp and excessive dandruff. They were male and aged 20-40. The volunteers were divided into groups and used the shampoos of the application cases and control cases to wash their hair once a day. Each time they washed their hair, they applied the shampoo evenly, massaged their scalp for 3 minutes, and then rinsed it with water. They did not use any other hair care products and continued to use the products for 60 days.

[0099] Immediately after the first shampoo, test the scalp oil content on the top of the head and record it as the initial scalp oil content before the experiment. After 12 hours of free activity, test the scalp oil content on the top of the head again and record it as the scalp oil content 12 hours before the experiment. Calculate the increase in scalp oil content 12 hours before the experiment using the following formula.

[0100] Increase in skin oil 12 hours before the experiment = Skin oil content 12 hours before the experiment - Initial skin oil content before the experiment.

After 12 hours of free activity, the scalp oil content on the top of the head was tested again and recorded as the 12-hour scalp oil content after the experiment. The increase in scalp oil content after 12 hours was calculated according to the following formula.

[0102] Increase in skin oil 12 hours after the experiment = Skin oil content 12 hours after the experiment - Initial skin oil content before the experiment.

[0103] The MPA580 multifunctional skin analyzer with an SM815 probe was used to test the skin's oil content.

[0104] The probe contains matte tape, which becomes translucent after absorbing grease. The more grease present, the greater the transparency. The amount of grease transmitted through the probe indicates the grease content, measured in μg / cm². 2 .

[0105] Experiment 4 Several volunteers were recruited. The volunteers had symptoms of itchy scalp and excessive dandruff. They were male and aged 20-40. The volunteers were divided into groups and used the shampoos of the application cases and control cases to wash their hair once a day. Each time they washed their hair, they applied the shampoo evenly, massaged their scalp for 3 minutes, and then rinsed it with water. They did not use any other hair care products and continued to use the products for 60 days.

[0106] Immediately after the first shampoo, test the skin moisture content of the scalp on the top of the head and record it as the initial skin moisture content before the experiment. After 4 hours of free activity, test the skin moisture content of the scalp on the top of the head again and record it as the skin moisture content 4 hours before the experiment. Calculate the skin moisture loss over time in the 4 hours before the experiment using the following formula.

[0107] Skin moisture loss over time 4 hours before the experiment = initial skin moisture content before the experiment - skin moisture content 4 hours before the experiment.

[0108] Immediately after the 60th shampoo, the skin moisture content of the scalp on the top of the head was tested and recorded as the initial skin moisture content after the experiment. After 4 hours of free activity, the skin moisture content of the scalp on the top of the head was tested again and recorded as the skin moisture content 4 hours after the experiment. The skin moisture loss over time 4 hours after the experiment was calculated according to the following formula.

[0109] Skin moisture loss over 4 hours after the experiment = initial skin moisture content after the experiment - skin moisture content 4 hours after the experiment.

[0110] When testing skin moisture content, a Corneometer CM825 is used. The higher the measured value, the higher the skin moisture content.

[0111] The detailed experimental data for Experiments 1-4 are shown in Tables 1 and 2.

[0112] Table 1

[0113] Table 2

[0114] According to Tables 1 and 2, all examples and comparative examples have good inhibitory effects on Malassezia furfur. However, the soothing effect of each example is significantly higher than that of the comparative example. At the same time, the oil control effect and the skin barrier repair effect of each application example are significantly better than those of the comparative application examples.

[0115] The results demonstrate that the combination of succinic acid with extracts of Coptis chinensis root, Sophora flavescens root, Polygonum cuspidatum root, Zanthoxylum bungeanum fruit, and Viola yedoensis not only effectively kills Malassezia furfur to reduce dandruff caused by bacterial secretions, but also alleviates scalp allergies, reducing dandruff caused by abnormal shedding of scalp keratinocytes due to allergic reactions. Simultaneously, it reduces sebum secretion, preventing Malassezia furfur from multiplying and forming dandruff more quickly, and promotes scalp barrier repair, making the scalp less prone to dryness and reducing abnormal shedding of keratinocytes caused by dryness. Thus, through the synergistic effect of multiple dimensions, it achieves long-lasting oil control and dandruff removal.

[0116] While each ratio also has good antibacterial effects and can solve the dandruff problem caused by Malassezia furfur secretions, its oil control effect is relatively average, and the hair is prone to becoming oily. Moreover, it is difficult to solve the dandruff problem caused by scalp damage, allergies, and dryness, resulting in a short duration of oil control and dandruff removal effects, which is difficult to meet the needs of consumers.

[0117] This specific embodiment is merely an explanation of this application and is not intended to limit it. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.
