Abstract

The invention discloses a sodium hypochlorite gel. The sodium hypochlorite gel comprises, by weight, 0.3 to 2.0% of sodium hypochlorite, 3 to 5% of a thickening agent, 0.1 to 2% of a stabilizing agent, and the balance water. According to a preparation method, sodium hypochlorite aqueous solution is prepared into the sodium hypochlorite gel, so that molecule movement in the system is reduced greatly, sodium hypochlorite stability is improved greatly. In using process, the sodium hypochlorite gel can be smeared at needed places, is convenient and safe to use, and is convenient for transportationand storage. It is confirmed by later embodiment and test that the sodium hypochlorite gel is stable in properties; the self life is as long as two years; compared with liquid sodium hypochlorite, the advantages of the sodium hypochlorite gel are that: the irritation performance is relatively low, using is convenient and safe, and transportation and storage are convenient; and in addition, the sodium hypochlorite gel possesses excellent killing effects on Escherichia coli 8099, Staphylococcus aureus ATCC6538, Pseudomonas aeruginosa ATCC15442, and Candida albicans ATCC10231. The invention also relates to a preparation method of the sodium hypochlorite gel.

Description

technical field [0001] The invention belongs to the technical field of disinfectant and bactericide, and in particular relates to a sodium hypochlorite gel. In addition, the invention also relates to a preparation method of the sodium hypochlorite gel. Background technique [0002] Sodium hypochlorite, with the chemical formula NaClO, is the hypochlorite of sodium. It is also a strong oxidant, bleach, disinfectant and deodorant. It is corrosive and is used in papermaking, textile, light industry, etc., and has the functions of bleaching, sterilization and disinfection. [0003] Sodium hypochlorite aqueous solution is commonly known as bleaching water. It is slightly yellow and has a chlorine-like smell. It is very pungent and extremely unstable. It is a by-product of the chlor-alkali industry. It is mainly used for bleaching of pulp and textiles, water treatment, hospitals, catering, agriculture, and animal husbandry. Disinfection and sterilization of industries, hotels and ...
