Description

Technical Field

[0001] This invention relates to the field of cosmetic technology, and in particular to an anti-dandruff and anti-itch shampoo containing plant extracts and its preparation method. Background Technology

[0002] Anti-dandruff and anti-itch shampoos work by using specific ingredients to inhibit fungi, regulate oil production, and repair the scalp barrier, thereby reducing dandruff and itching.

[0003] Most existing shampoos rely on sulfate surfactants (such as sodium lauryl ether sulfate) for powerful cleaning, but these can easily damage the scalp barrier, causing dryness, itching, and redness. Although some products have introduced amino acid surfactants (such as sodium lauroyl sarcosinate) or plant extracts (such as centella asiatica and he shou wu) to improve gentleness, they still suffer from problems such as insufficient cleansing power and strong irritation. Summary of the Invention

[0017] To address the problems of insufficient cleansing power and strong irritation in existing technologies, this invention provides an anti-dandruff and anti-itch shampoo containing plant extracts, which is composed of phase A, phase B, and phase C in a mass ratio of 1:(0.2-0.5):(0.1-0.3). Phase A comprises the following components in parts by weight: 50-70 parts water, 2-5 parts cocamidopropyl hydroxysulfonate betaine, 0.01-0.1 parts tetrasodium EDTA, 5-8 parts sodium lauryl ether sulfate, 0.2-0.8 parts sodium chloride, 0.3-0.6 parts hydroxypropyl guar gum hydroxypropyl trimethylammonium chloride, and 0.1-0.3 parts citric acid; Phase B comprises the following components in parts by weight: 10-15 parts water, 1-3 parts sodium lauroyl sarcosinate, 0.1-0.3 parts sodium chloride, 1-2 parts sodium lauroyl glutamate, 0.1-0.5 parts hydrogenated castor oil, 1-1.5 parts sodium laurate taurate, 0.5-0.8 parts phenoxyethanol, 0.1-0.5 parts hydroxyethyl urea, 0.1-0.3 parts sodium PCA, 0.1-0.3 parts glycine, 0.1-0.3 parts PPG-3 octyl ether, and 0.01-0.05 parts menthol; Phase C comprises the following components in parts by weight: 10-20 parts water, 0.1-0.4 parts polyquaternium-7, 0.5-0.8 parts 1,2-hexanediol, 0.1-0.3 parts p-hydroxyacetophenone, 0.1-0.5 parts maltodextrin glucoside, 1-1.5 parts butylene glycol, 0.1-1 parts glycerin, 0.01-0.1 parts hexamididine di(hydroxyethyl sulfonic acid) salt, and 5-15 parts plant extracts; The plant extracts consist of Tremella fuciformis polysaccharide, oat alkaloids, dihydroquercetin, cinchona bark extract, wampee leaf extract, Ilex chinensis root extract, Schefflera heptaphylla extract, and rosemary leaf oil in a mass ratio of (0.1-0.3):(0.1-0.3):(0.05-0.1):(0.2-0.4):(0.05-0.08):(0.05-0.08):(0.05-0.08).

[0018] In this invention, the polysaccharide is extracted from tremella. Its molecules contain a large number of hydroxyl groups, forming a three-dimensional network structure, which has a strong water-locking ability and can reduce symptoms such as scalp redness and itching by inhibiting inflammatory responses. Oat alkaloids are extracted from oats and have the ability to scavenge free radicals, protect the integrity of hair follicle cell membranes, and relieve symptoms such as scalp redness and itching. Dihydroquercetin is extracted from larch bark, grape seeds, onions, citrus fruits, etc. It can inhibit inflammatory signaling pathways, reduce the level of pro-inflammatory factors, and alleviate scalp inflammation. Cinchona bark extract is obtained from the bark of the cinchona tree. It contains alkaloids that can astringe sebaceous glands, reduce oil secretion, and directly interfere with fungal metabolism, thus inhibiting dandruff formation. The extract of wampee leaves is obtained from wampee leaves and is rich in flavonoids, which can scavenge free radicals and protect hair follicle cells from oxidative damage. Ilex chinensis root extract, obtained from Ilex chinensis root, can reduce scalp inflammation by inhibiting the production of inflammatory factors. Schefflera heptaphylla extract, obtained from Schefflera heptaphylla, can inhibit inflammatory responses and alleviate symptoms such as scalp redness and itching. Rosemary leaf oil is extracted from rosemary leaves and is rich in polyphenolic compounds, which can scavenge free radicals and protect hair follicle cells from oxidative damage.

[0019] In the above system, the present invention uses plant extracts composed of Tremella fuciformis polysaccharide, oat alkaloids, dihydroquercetin, cinchona bark extract, wampee leaf extract, Ilex chinensis root extract, Schefflera heptaphylla extract, and rosemary leaf oil as a plant active repair system. Combined with cleansing system component A and amino acid soothing system component B, a multi-target synergistic compound is formed to achieve a precise balance between cleansing power and soothing properties.

[0020] In the embodiments, the plant extract is composed of Tremella fuciformis polysaccharide, oat alkaloids, dihydroquercetin, cinchona bark extract, wampee leaf extract, Ilex chinensis root extract, schefflera oleracea extract, and rosemary leaf oil in a mass ratio of 0.1:0.2:0.06:0.2:(0.06-0.08):(0.05-0.06):(0.05-0.06):(0.07-0.08).

This combination of plant extracts has the best effect.

[0021] In one embodiment, in phase C, the mass ratio of plant extract to polyquaternium-7 and maltodextrin is 1:(0.01-0.1):(0.08-0.1). The combination of these three components can enhance the antibacterial and anti-inflammatory effects. Preferably, the mass ratio of plant extract to polyquaternium-7 and maltodextrin is 1:0.08:0.09.

[0022] In phase A, the mass ratio of cocamidopropyl hydroxysulfonate betaine, sodium lauryl ether sulfate, and hydroxypropyl guar hydroxypropyl trimethyl ammonium chloride is 1:(1-2):(0.1-0.2). Preferably, the mass ratio of cocamidopropyl hydroxysulfonate betaine, sodium lauryl ether sulfate, and hydroxypropyl guar hydroxypropyl trimethyl ammonium chloride is 1:2:0.2, which can improve the cleaning performance of the system.

[0023] In phase B, the mass ratio of sodium lauroyl sarcosinate, sodium lauroyl glutamate, sodium laurate taurate, and PPG-3 octyl ether is 1:(0.8-1.2):(0.8-1.2):(0.1-0.3); preferably, the mass ratio of sodium lauroyl sarcosinate, sodium lauroyl glutamate, sodium laurate taurate, and PPG-3 octyl ether is 1:1:1.2:0.2 to optimize the soothing properties of the system.

Each volunteer used shampoo (Examples 1-4, Comparative Examples 1-10) to wash their hair every night, massaging their scalp thoroughly for 5 minutes before rinsing. Shampooing was performed every other day for two consecutive months. The study assessed dandruff, scalp itching, and a comprehensive evaluation (based on cleansing power and soothing effect). Volunteers self-rated their scalp using a four-level scale: 1 = no improvement, 2 = slight improvement, 3 = significant improvement, 4 = complete improvement. The test results are shown in Table 3.
