Abstract

The invention is suitable for the field of daily chemical products, and provides a shower gel, and a preparation method and application thereof. The shower gel comprises the following ingredients: sodium laureth sulfate, sodium lauryl sulfate, alkyl polyether quaternary ammonium salt, alkylamine or ammonium chloride with an amide group, alkyl amide group betaine, alkyl amide, sodium chloride, essence and purified water. In the shower gel provided by the embodiment of the invention, the alkyl polyether quaternary ammonium salt of which the molecular structure contains an ethylene oxide group, an alkylammonium salt cationic surface active agent containing an amide group and ampholytic surfactant of alkyl dimethyl betaine are selected to be compounded and added into a shower gel product, theproduct is free from problems, including phase separation, sedimentation and the like, in addition, the viscosity of the shower gel can be favorably stabilized, and therefore, a phenomenon that a shower gel product is low-temperature "jelly-like" can be effectively solved.

Description

technical field [0001] The invention belongs to the field of daily chemical products, and in particular relates to a shower gel and its preparation method and application. Background technique [0002] Shower gel formulations currently on the market are mainly composed of anionic surfactants (such as fatty alcohol polyether sulfate sodium AES, N-acyl amino acids and their salts), nonionic surfactants (such as alkyl alcohol amide 6501, alkyl glycosides APG), amphoteric surfactants (such as betaines, imidazolines), compound emollients, moisturizers and essences. [0003] All shower gels produced with similar formulas have a sharp increase in viscosity at low temperatures (about 5-8°C). At 5°C, the viscosity usually exceeds 60,000mPa.s, showing a "jelly" phenomenon, which is difficult for consumers to use. Pump or squeeze out, and because this "jelly" liquid does not have good fluidity, it is difficult to knead and foam during use, which affects consumers' pleasure in use. Co...
