Description

Technical Field

[0001] The invention relates to the technical field of shampoo preparation, in particular to an anti-dandruff and antipruritic shampoo containing a Corydalis root extract and a preparation method thereof. Background Art

[0002] With the rapid development of science and technology, the development of anti-dandruff products in the market today is gradually segmented and diversified. How to use anti-dandruff products and achieve better anti-dandruff effects is an important topic in the field of cosmetology. In view of the different causes of dandruff, the compound plant anti-dandruff and antipruritic agent made from Chinese herbal plant extracts can promote blood circulation, improve the vitality of scalp cells, regulate the metabolism of scalp cells, improve the microenvironment of scalp cells, and prolong the life cycle of scalp cells, thus reducing the production of dandruff and itching from the internal causes; from the external causes, it not only contains effective plant ingredients that can kill Malassezia, but also contains a large amount of alkaloids that can effectively remove the excessive sebum secreted on the scalp, and sebum is the breeding ground for the survival of Malassezia. In this way, by killing and inhibiting Malassezia from the external causes, the number of Malassezia on the scalp is controlled within the normal range, the peroxide that affects the production of dandruff is reduced, and the external channels of dandruff production are fundamentally blocked, thereby effectively removing dandruff and stopping itching. Plant anti-dandruff and antipruritic agents mainly block the external channels of dandruff production through methods such as sterilization, antioxidant effects and decomposition of peroxides. At the same time, after being absorbed by the skin, the plant anti-dandruff and anti-itching agent will not accumulate in the skin. On the contrary, it will be quickly decomposed without any residue. Therefore, it has no adverse effects on the skin after being absorbed by the skin. It is a mild and safe anti-dandruff and anti-itching agent.

[0003] Corydalis yanhusuo is a plant of the genus Corydalis in the family Papaveraceae, which has a long history of use as a traditional Chinese medicine. Corydalis yanhusuo root extract has anti-inflammatory and antibacterial effects, soothing and anti-allergic effects, and rapid redness and itching reduction. Making full use of Corydalis yanhusuo root extract, making it into a plant anti-dandruff and antipruritic agent, and designing and developing shampoo products that can improve the scalp microenvironment, reduce dandruff and itching, has important application prospects and economic value.
