Description

TECHNICAL FIELD

[0001] The present application relates to a shampoo, in particular a shampoo with tea saponin and tea oil and a preparation method thereof. BACKGROUND

[0002] In industrial production, the current market shampoo is mainly synthesized by using sodium fatty alcohol polyoxyethylene ether sulfate, alkyl glucoside, ammonium lauryl sulfate, coconut oil fatty acid diethanolamide, polyquaternary ammonium salt, sulfate, pearl double fat and other compounds as raw materials. The surfactant is a key factor affecting the shampoo, which requires high foaming, good emulsifying, strong detergency, good stability, easy cleaning, non-toxic and harmless, and easy storage.

[0003] Experiments show that a large amount of tea saponin can be extracted from tea dregs, and tea saponin is a natural non-ionic surfactant with good foaming, dispersing, emulsifying, wetting and other functions. Combined with the functional characteristics of tea saponin itself, tea saponin can be widely used in traditional Chinese medicine shampoo. Tea saponin is a natural surfactant, which is non-toxic and harmless, and can not only improve the performance of the shampoo, but also reasonably utilize the tea dregs resources, which meets the current national resource recycling principle, that is, environmental protection and convenience.

[0004] At present, tea saponin has been applied to shampoo, but basically it is by adding pure tea saponin and other component structures, but there is no more prior research on how to make tea saponin and tea oil cooperate well. SUMMARY

[0079] Optimization experiment of tea saponin tea oil microemulsion

[0080] The tea oil was used as oil phase, tea saponin and fatty alcohol polyoxyethylene ether sodium sulfate 1:1 mixed as emulsifier, 1,2-propanediol as co-emulsifier. First, the complex emulsifier was prepared according to the mass ratio of emulsifier to co-emulsifier = 4:1, 3:2, 2:3, 1:4, 1:1, then the complex emulsifier and tea oil were mixed according to the mass ratio of 8:2, 6:4, 5:5, 4:6, 2:8, and the total mass of the complex emulsifier and tea oil was fixed at 1.0 g. The emulsion was formed by adding appropriate amount of distilled water to the complex oil phase mixture, and the emulsion stability was observed. The phase inversion point of the system (i.e. from turbidity to clear and stable state) was recorded, and the pseudo-ternary phase diagram was drawn. By comparing the area size of the microemulsion region, the formation ability of the microemulsion was analyzed, and the results were used as the basis for establishing the tea saponin-tea oil complex shampoo and conditioner formula.

[0081] Preparation of emulsifier and co-emulsifier: 2.0 g of fatty alcohol polyoxyethylene ether sodium sulfate and 2.0 g of tea saponin were weighed into a 50 ml beaker, 1.0 g of 1,2-propanediol was added to the beaker, a magnetic stirrer was added, and it was dissolved in a 60°C water bath with stirring to prepare a complex emulsifier.

[0082] Complex emulsifier and tea oil complex: the complex emulsifier and tea oil were mixed in a mass ratio of 8:2, 6:4, 5:5, 4:6, 2:8 and added to a 25 ml beaker, the total mass of the complex emulsifier and tea oil was fixed at 1.0 g, a magnetic stirrer was added, and it was heated and stirred in a 60°C water bath. The emulsion was formed by slowly adding an appropriate amount of distilled water, and the emulsion stability was observed.

[0083] Figures 1-5 For emulsifier and co-emulsifier mass ratio of 4:1, 3:2, 2:3, 1:4, 1:1, the corresponding pseudo-ternary phase diagram of tea oil-emulsifier-co-emulsifier microemulsion tea oil under different ratios was drawn.

[0084] According to the pseudo-ternary phase diagram, the microemulsion region was determined, and it can be seen that the microemulsion area with emulsifier and co-emulsifier mass ratio of 4:1 is the largest, so the emulsifier and co-emulsifier mass ratio of 4:1 is determined as the basic formula. An appropriate amount of distilled water was added to the complex oil phase mixture to form an emulsion

[10] , and the emulsion stability was observed to see if there was a layering phenomenon.

[0085] 2.0 ml of distilled water was added to 5 test tubes and shaken for 1 min Figure 6 , it can be observed that Figure 6 (1) the 5 test tubes were in emulsion state; after 2 h, it can be observed that Figure 6 (2) a, e test tubes began to separate; after 4 h, it can be observed that (3) c, d test tubes also began to separate.

[0086] By Figure 6 It can be seen that the emulsion with the mass ratio of composite emulsifier to tea oil of 6:4 is not layered, indicating that the emulsion has the best stability, and it can be determined that the mass ratio of 6:4 of the composite emulsifier to tea oil is the best compounding ratio.

Therefore, the washing and caring sample has the highest DPPH free radical scavenging rate, which is 30% higher than that of Pantene, and 57.88% higher than that of the commercially available traditional Chinese medicine hair shampoo. The greater the DPPH free radical scavenging rate is, the stronger the antioxidation is. Therefore, the washing and caring sample prepared in the laboratory has the highest antioxidation performance.

[0165] From Figure 11 It can be known that the transmittance of the washing and caring sample under ultraviolet light is 30%, the Pantene hair shampoo is 31.67%, and the traditional Chinese medicine hair shampoo reaches 55%. Tea oil has the ability of anti-ultraviolet radiation. The washing and caring product is compounded with tea oil, and the anti-ultraviolet radiation performance is designed. According to the preliminary data, the transmittance of the washing and caring sample under ultraviolet light is the lowest, which is 1.67% lower than that of Pantene, and 25% lower than that of the commercially available traditional Chinese medicine hair shampoo. The lower the transmittance of ultraviolet light is, the better the anti-ultraviolet radiation performance is. Therefore, the washing and caring sample prepared in the laboratory has the highest anti-ultraviolet radiation performance. As Figure 12 shown.

[0166] The repair ability of the tea saponin-tea oil compounded hair washing and caring product.

[0167] The keratin formed in the hair has rich high-sulfur proteins, so that the hair surface has polar groups and negative charges and has adsorption properties

[12] , the concentration of methylene blue before and after adsorption can represent the damage degree of the hair, the higher the concentration of adsorbed methylene blue, the more serious the damage degree of the hair, and the concentration after washing the hair with the washing and protecting sample and the TRESemme shampoo can represent the repair ability of the product. A certain gradient concentration of 40mg / L methylene blue solution is set, and the standard curve is determined at the characteristic absorption wavelength (662nm), as shown in Figure 13 .

[0168] The absorbance of the undamaged hair, damaged hair and damaged hair washed with the washing and protecting sample and the TRESemme shampoo is determined, and the adsorption amount of the hair sample to methylene blue is calculated, and the results are shown in Figure 12 .

[0169] It can be known from Figure 13 that the adsorption amount of the hair to the methylene blue solution increases with the increase of the adsorption time. After the damaged hair is washed with the washing and protecting sample and the TRESemme shampoo, the adsorption amount of the hair sample is obviously reduced, which indicates that the washing and protecting sample and the TRESemme shampoo both have a certain repair function for the damaged hair scale. Then, the adsorption amount data of the washing and protecting sample and the TRESemme shampoo are compared. Because the TRESemme shampoo contains a silicon oil component, the silicon oil has a repair function for the hair, so the repair effect of the TRESemme shampoo is better. However, the tea saponin also has a repair function for the hair, and compared with the silicon oil, the tea saponin is more cost-effective and has a wider source. The experiment shows that the tea saponin can be used to replace the silicon oil to achieve the required effect.

[0170] In summary, the tea saponin and the tea oil have many good properties. In the present application, the tea saponin and the tea oil are compounded in a specific ratio, and the pseudo-three-phase diagram is used to compound the tea saponin and the tea oil, which provides a theoretical basis for the stability of the tea saponin and the tea oil in the washing and protecting product. The performance of the prepared tea saponin-tea oil shampoo is detected, and the results show that the sensory and physical and chemical indexes of the shampoo meet the national standards, and the shampoo has good foam performance, decontamination, rheological property, antioxidant property, anti-ultraviolet radiation property and repair ability, and all the indexes meet the national standard requirements. In addition, the tea saponin and the tea oil are natural substances, and the shampoo prepared by compounding the tea saponin and the tea oil can meet the demand of people for natural and green daily chemicals, and the functions of the tea saponin and the tea oil can be exerted to provide excellent performance in the shampoo.
