and S3, sequentially adding a surfactant, a rheology regulator, a micro-nano emulsion, a preservative and a chelating agent into the mixture obtained in the step S2, uniformly mixing, stirring, cooling to 40-45 ℃, adding a pH regulator and sodium chloride, and uniformly stirring to obtain the nano-emulsion.
The washing and nursing product obtained through the intensive research not only has high foam richness, but also can release grease in the product while cleaning oil stains on hair and skin, and the product is left on the surface of the skin after being washed, so that the product has certain moistening effect and moisturizing effect.

The applicant also found that when the rheology modifier is selected from at least one of hydroxypropyl starch phosphate, acrylate/C10-31 alkanol acrylate cross-linked polymer and acrylate copolymer, and is in a certain proportion, the obtained washing care product has no delamination phenomenon even when being placed at high temperature for 3 months. The reason for guessing is: the rheology modifier contains a large number of active groups which can be mutually cooperated with other components such as sodium laureth sulfate, cocamidopropyl betaine and the like to form a mutually-crosslinked thixotropic network structure, so that the phenomenon that the particles are aggregated to be layered or form precipitates is prevented. When the concentration of one of them is out of this range, the stability at room temperature and the stability at high temperature are lowered because the formed equilibrium system is broken.
The present invention will be specifically described below by way of examples. It should be noted that the following examples are only for illustrating the present invention and should not be construed as limiting the scope of the present invention, and that the insubstantial modifications and adaptations of the present invention by those skilled in the art based on the above disclosure are still within the scope of the present invention.
