Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of shampoo preparation, and relates to a plant-extracted herbal anti-dandruff and antipruritic shampoo and a preparation method thereof. Background Art
[0002] Dandruff and scalp itching are the two most common problems, which not only affect personal image, but also may cause psychological pressure and decreased quality of life. Studies have shown that the generation of dandruff is closely related to factors such as impaired scalp barrier function, fungal infection (such as Malassezia) and excessive oil secretion of the scalp. In addition, the stimulation of the external environment, the improper use of chemical products and long-term mental stress can also aggravate the severity of scalp problems. Although traditional anti-dandruff and anti-itching shampoo products can relieve scalp discomfort to a certain extent, some products contain highly irritating chemical ingredients, and long-term use may further damage the scalp barrier and cause new health problems. Therefore, the development of a gentle and efficient anti-dandruff and anti-itching shampoo has become an urgent need of the market and consumers.
[0003] In recent years, the application of plant extracts in the field of personal care has received widespread attention. Unlike traditional chemical active agents, plant-derived herbal ingredients are ideal for improving scalp health due to their natural, mild and multifunctional properties. Many herbs have significant antibacterial, anti-inflammatory, antipruritic and oil secretion regulating effects. For example, Gleditsia sinensis extracts are rich in saponin compounds, which can gently clean the scalp; traditional Chinese herbal medicines such as Polygonum multiflorum and Platycladus orientalis are widely used in traditional Chinese medicine to prevent hair loss and promote hair growth; Salvia miltiorrhiza and Sophora flavescens extracts have good anti-inflammatory and antibacterial properties, which help inhibit scalp infections; and Dictamni cortex is used to relieve scalp sensitivity and itching problems due to its unique antipruritic effect. Through scientific proportions, these herbal ingredients can play a synergistic role in scalp care, effectively inhibiting the main causes of dandruff and repairing damaged scalp barriers, providing consumers with safer and more natural solutions.
[0004] Although there are many anti-dandruff and anti-itching shampoo products on the market, many existing technologies still have shortcomings in product performance and user experience. First, many products use chemical active agents or drug ingredients, such as pyrithione zinc and selenium sulfide. Although they can inhibit dandruff and relieve itching in the short term, these ingredients are highly irritating to the scalp, which can easily lead to dry scalp or further damage the scalp barrier. Secondly, in existing plant-based shampoos, the activity of many herbal ingredients is unstable and they are easily lost due to light, oxidation or long-term storage. In addition, since herbal extracts are generally poorly soluble, it is difficult to evenly distribute them in shampoo products, resulting in poor use effects. Traditional preparation processes also often ignore the bioavailability of herbal active ingredients and cannot fully exert their efficacy. Therefore, it is particularly important to develop an efficient, stable and mild anti-dandruff and anti-itching shampoo using plant extracts, which will fill the gaps in existing technologies and meet consumers' demand for natural and healthy products. Summary of the invention
[0005] The invention relates to a plant extract herbal anti-dandruff and antipruritic shampoo and a preparation method thereof, and belongs to the technical field of shampoo preparation. The invention uses piroctone ethanolamine salt as an anti-dandruff agent, which can effectively inhibit the fungi that cause dandruff, and at the same time, compound herbal active ingredients to adjust the balance of scalp flora, improve the water-oil balance of the scalp, and thus improve the immunity of the scalp; the surfactant adopts a compounding scheme of sodium laureth sulfate and sodium lauroyl sarcosinate, which not only ensures the cleaning power but also reduces the stimulation to the scalp; in the preparation process, chitosan is used to microencapsulate the herbal active ingredients, that is, to delay the oxidative degradation of the active ingredients, and also to achieve the sustained release of the active ingredients, thereby extending the duration of the efficacy.
