[0050] In a specific embodiment, the present application provides a method for preparing a silicone oil-free sulfate-free shampoo with high conditioning, which is characterized in that it comprises the following steps:
[0051] (1) Add water, sodium lauroyl sarcosinate, cocamidopropyl betaine, disodium EDTA, glyceryl laurate, cocoamidomethyl monoethanolamine in a stirring pot, and heat and stir;
[0052] (2) When the temperature rises to 70°C, add polyquaternium-10, and stop heating after stirring evenly;
[0053] (3) When the temperature is lowered to 60°C, add PCA glycerol oleate, mustard oil, xylitol glucoside, anhydroxylitol and xylitol, and stir evenly;
[0054] (4) When the temperature is lowered to 45° C., add preservatives, essence, and citric acid, stir evenly, and then stop stirring to obtain the silicone-free, sulfate-free shampoo with high conditioning properties.

Embodiment 4
[0080] Embodiment 4 Hair combing performance test evaluation:
[0081] Experimental equipment: INSTRON static carding instrument
[0082] Test Methods:
[0083] All the natural untreated Asian hair tresses to be tested were first washed with Comparative Example 1 until there was no foam, and then wet combed and dry combed on the INSTRON static combing instrument. Then use the shampoos of Examples 1-3 and Comparative Examples 2-3 to perform a wet combing test; after the hair tresses are naturally dried at a room temperature of 25° C. and a humidity of 60%, a dry combing test is performed. According to the dry and wet hair combing work of each hair bundle twice before and after, the improvement rate of dry and wet hair combing ability is calculated.
[0084] Table 2 lists the hair combing force test data of Examples 1-3, Comparative Examples 1-3 and a commercially available shampoo. This commercially available shampoo is Head & Shoulders anti-dandruff shampoo containing silic...
