Description

Shower gel and preparation method thereof Technical Field The application relates to the field of daily chemical products, in particular to a shower gel and a preparation method thereof. Background The bath lotion is a liquid cleanser applied to the body during bath. The body sebum amount and perspiration amount are smaller than those of the face, but apocrine sweat glands which produce body odor by perspiration are almost spread over the whole body, and the body wash is essentially a skin cleanser for cleaning and moisturizing the skin outside the face, and can remove dirt, grease, perspiration and the like on the skin surface. Along with the continuous improvement of the living standard of people, the bath cream is popular with people due to the advantages of convenient use, good detergency and the like, and gradually replaces perfumed soap, thereby becoming a necessary article for families. The prior shower gel comprises water, a surfactant, a pH regulator, a viscosity regulator and the like. The surfactant forms micelle in water, the volume of micelle is easy to expand along with the rise of temperature, the movement resistance is reduced, the viscosity of the bath foam is reduced, the bath foam becomes thinner, the dosage is difficult to control, the bath foam is difficult to knead and foam, in addition, the viscosity is reduced, the sedimentation layering phenomenon is easy to occur, and the cleaning effect is further influenced. On the contrary, at low temperature, the micelle shrink and intertwining are enhanced, so that the viscosity is increased, the extrusion is difficult, even if the extrusion is laborious, the too thick system is difficult to rapidly and uniformly spread, fine foam is difficult to generate, and the cleaning effect and the experience are affected. Disclosure of Invention The application mainly aims to provide a shower gel and a preparation method thereof, and aims to solve the problems that the viscosity of the existing shower gel is obviously increased at low temperature and is obviously reduced at high temperature.

Wherein, cocoamide MEA can significantly increase the viscosity of the liquid and form a stable foam liquid film. PEG-120 methyl glucose dioleate is a mild surfactant, and the molecular structure of the PEG-120 methyl glucose dioleate can interfere with the crystallization process of cocamide MEA at low temperature, so that the uniformity and fluidity of the product at low temperature are ensured. Sodium carboxymethyl starch is a thixotropic thickener which provides excellent suspending ability, prevents precipitation of certain functional ingredients in the product, and also imparts excellent suspension flowability and sag resistance to the product. The acrylic acid-acrylic ester copolymer is thickened by swelling in water to form a three-dimensional network structure, is similar to carboxymethyl starch sodium, has excellent suspending capability, and improves the high-temperature and low-temperature stability of the product. Sodium chloride as a low cost thickener can increase viscosity, improve emulsion stability and reduce cost at proper concentrations. The bacteriostat formed by compounding the macleaya cordata extract and the tea polyphenol has broad-spectrum bacteriostasis. The macleaya cordata extract has high content of alkaloid such as sanguinarine and the like, can realize strong and rapid cell membrane destruction and enzyme inhibition, and has antibacterial effect.
