Description

Technical Field

[0001] The invention belongs to the technical field of skin care products, and particularly relates to a herbal plant extract anti-dandruff and anti-itching shampoo. Background Art

[0002] Scalp itching is a common scalp health problem with complex and diverse causes, including microbial imbalance (such as excessive proliferation of Malassezia), inflammatory responses (such as seborrheic dermatitis or contact dermatitis), impaired scalp barrier function, environmental irritants (such as pollutants or hard water), and chemical residues (such as accumulation of silicone oil or sulfate surfactants). Existing shampoo products for scalp itching mainly achieve their anti-itching function through the following mechanisms, but they still have significant limitations: Antimicrobial ingredients, such as zinc pyrithione (ZPT) and ketoconazole, are widely used to inhibit Malassezia. However, long-term use can lead to the development of drug-resistant strains, and ZPT's use has been restricted in some countries due to environmental toxicity concerns. Furthermore, while ingredients like climbazole can rapidly kill bacteria, they are indiscriminately destructive to the scalp's commensal flora, potentially causing secondary imbalances in the microbiome.

[0003] Anti-inflammatory and antipruritic active ingredients, such as salicylic acid and dipotassium glycyrrhizate, work by inhibiting histamine release or blocking the TRPV1 itch receptor pathway. However, salicylic acid can exacerbate barrier damage during exfoliation, while synthetic antihistamines like diphenhydramine suffer from low transdermal absorption (<2%) and a short duration of action (<8 hours). Natural plant extracts (such as menthol and tea tree oil) offer an instant cooling effect but lack long-lasting anti-inflammatory mechanisms, and their volatile components are easily lost during rinsing.

[0004] Physical barrier repair technology, using lipid supplements like ceramides and squalane, can repair the stratum corneum structure. However, traditional emulsification systems struggle to achieve targeted deposition of lipid components on a moist scalp, resulting in a bioavailability of less than 5%. Silicone film-forming agents, while providing temporary relief from dryness, can also form a hydrophobic film that hinders the penetration of active ingredients, creating a vicious cycle of "relieving itching, blocking it, and then further itching."

[0005] Existing products often utilize a single mechanism of action, lacking the coordinated regulation of multiple pathways: antibacterial, anti-inflammatory, and barrier repair. Therefore, there is an urgent need to develop a novel anti-itch shampoo system to address these issues. Summary of the Invention

[0006] The purpose of the present invention is to provide a herbal plant extract anti-dandruff and anti-itching shampoo, which, through the synergistic effect of multiple plant extracts and the optimization of the formula, achieves multi-dimensional blocking of itching factors and long-term regulation of the scalp microenvironment while ensuring the washing and care performance.

[0031] Anti-dandruff and anti-itching effect test Test subjects: those with high sebum secretion 60 volunteers (15 males and 15 females aged 18-40; 15 males and 15 females aged 41-58) with itchy scalps and excessive dandruff were selected as trial subjects and divided into 6 groups of 10 subjects each. Before the test, there was no statistical difference in the conditions of the subjects in each group.

[0032] Instructions: Each group used the shampoo prepared in the example and comparative example, washing their hair every two days. Each time, ensure that the shampoo was massaged for 200 seconds and rinsed for 100 seconds. This was continued for 30 consecutive days. The evaluation results were recorded on the 2nd, 10th, 20th, and 30th day after use.

[0033] Evaluation criteria: Using the sensory evaluation method, if the scalp is not itchy and there is no dandruff, the effect is significant, which is recorded as Grade A; if the scalp is slightly itchy with a small amount of dandruff, it is recorded as Grade B; if the scalp is moderately itchy with a lot of dandruff, it is recorded as Grade C; if the scalp is severely itchy with a lot of dandruff, it is recorded as Grade D.
