Abstract

The invention discloses a multifunctional liquid soap containing an amino propanesulfonic acid inner salt structure, and a preparation method for the multifunctional liquid soap. The preparation method comprises the following steps of: firstly, carrying out enzymatic degradation on starch to prepare degrading starch; under a function of horseradish peroxidase, carrying out modified starch graftingby 3-[ Dimethyl- [ 2-(2-methylprop-2-enoyloxy) ethyl ] azaniumyl ] propane-1-sulfonate; then, preparing a copolymer of acrylic acid, the 3-[ Dimethyl- [ 2-(2-methylprop-2-enoyloxy) ethyl ] azaniumyl] propane-1-sulfonate and allyl alcohol ethoxylate; enabling animal oleic acid to react with methoxypolyethylene glycol to react to prepare animal oleic acid methoxypolyethylene glycol ester; and compounding the prepared grafted modified starch, copolymer and animal oleic acid methoxypolyethylene glycol ester with lauryl sodium sulfate, acrylic acid, sodium methallyl sulfonate, sodium tripolyphosphate, triterpenoid saponin, isothiazolinone, citric acid, essences, pigments and the like to prepare an ecological liquid soap containing the amino propanesulfonic acid inner salt structure. The product is friendly to environment, exhibits small irritation on the skin of the human body and the like, has powerful sterilization and detergency and has high cost performance.

Description

technical field [0001] The invention relates to detergents, in particular to a multifunctional hand sanitizer containing aminopropanesulfonic acid internal salt amphoteric structure and a preparation method thereof. Background technique [0002] Washing your hands frequently and knowing how to wash your hands is the most effective, simplest and feasible way to control the spread of diseases and prevent infection. It has a good preventive effect on diseases transmitted by the digestive tract and diseases transmitted by the respiratory tract. The SARS epidemic in 2003 made people generally improve their self-protection awareness in daily life. The most common self-protection habit is to wash their hands frequently and know how to wash their hands. The spread of the new crown pneumonia epidemic that began around the Spring Festival in 2020 is another reminder People should start from their daily habits to improve their awareness and behavior of self-protection. Washing hands fr...
