The applicant develops a tea oil shampoo, but finds that the satisfaction degree of consumers on the shampoo in summer is low, and the applicant researches and discovers that the oily substances flocculate or float up mainly due to the fact that the temperature of the shampoo in summer is too high. A large number of researches show that the tea oil shampoo disclosed by the invention has good stability in summer. The method is probably because the surfaces of the N-lauryl-N-methylglucamide and the cationic guar gum are charged, then the N-lauryl-N-methylglucamide and the cationic guar gum form micro-emulsion with water and the tea oil under the action of other surfactants, meanwhile, a double electric layer of emulsion droplets can be formed by adding sodium chloride, so that the repulsive force between systems is reduced, then the compatibilization effect of the micro-emulsion is increased under the action of C16-18 alcohol, and the tea oil can be better fixed in the micro-emulsion and cannot be separated out.

Meanwhile, the interaction of sodium lauroyl glutamate and sodium lauroyl sarcosinate with the tea saponin reduces the greasy feeling of the tea oil, so that the refreshing feeling of the shampoo is enhanced.

Although N-lauryl-N-methylglucamide increases the stability of the system to some extent, but also the irritation of the shampoo, the applicant has found through a large number of experiments that the use of specific lauryl surfactants and coco surfactants in the present invention can reduce the irritation of the shampoo, especially the irritation of N-lauryl-N-methylglucamide, under the action of the plant extract.

In one embodiment, the C16-18 alcohol is available from Shanghai Yichuan chemical technology, Inc. under the designation 16/18 alcohol.

In one embodiment, the plant extract is a combination of lemon extract, pomegranate extract and zanthoxylum extract, and the weight ratio of the plant extract to the pomegranate extract is 1: (2-3): (4.5-5); preferably 1: 2.5: 4.8.

in one embodiment, the lemon extract, the pomegranate extract, and the zanthoxylum extract are all available from shanxi milkang biotechnology limited.

The existing shampoo contains preservatives, and the shampoo prepared previously also contains a small amount of preservatives, so the satisfaction degree of consumers is common. The applicant finds that the specific plant extract used in the system can better prolong the shelf life of the shampoo under the synergistic effect, and the residual and toxic and side effects are not easy to occur under the action of the preservative.

In one embodiment, the emulsifier is dioctyl sodium sulfosuccinate.

In one embodiment, the dioctyl sodium sulfosuccinate is available from Shanghai Bo Xueshi, Inc. under the designation Eurowet PG 70.

In one embodiment, the acidic pH adjusting agent is selected from at least one of malic acid, citric acid, fumaric acid.

In a preferred embodiment, the acidic pH adjusting agent is citric acid (CAS number 77-92-9).

The applicant has found that the stability of the shampoo is better when citric acid is used as an acidic pH regulator, probably because citric acid has a certain antibacterial property, and the citric acid and the plant extract have a synergistic effect to achieve a better sterilizing effect, so that the damage of bacterial microorganisms to the shampoo system can be reduced.

The choice of the chelating agent is not limited and all chelating agents commonly used in cosmetic shampoos are suitable for use in the present system. In a preferred embodiment, the chelating agent is disodium EDTA (CAS number: 139-33-3).

The invention selects EDTA disodium as the chelating agent and can improve the oxidation resistance of the tea oil to a certain extent.

In order to make the shampoo have better smell, in one embodiment, the raw materials of the tea oil shampoo further comprise 0.1-0.3 part by weight of essence, and the essence is commonly used in the field of shampoos and can be selected according to needs.
