The invention discloses an efficient and stable sodium hypochlorite disinfectant, which is prepared from the following raw materials in percentage by mass: 95 to 100 percent of sodium hypochlorite, 0.1 to 5 percent of stabilizer, 0.01 to 2 percent of surfactant, 0.01 to 0.5 percent of co-stabilizer, 0.05 to 0.2 percent of photo-thermal stabilizer, 0.1 to 5 percent of pH regulator and 0.01 to 0.2 percent of essence. High-performance surfactants, namely sodium dodecyl diphenyl ether disulfonate and dodecyl dimethyl amphoteric betaine, have good compatibility in a sodium hypochlorite solution with strong alkalinity and strong oxidizing property, so that the stability of sodium hypochlorite is ensured, the sterilization performance is improved, and a certain cleaning capability is provided; the photo-thermal stabilizer can inhibit the decomposition effect of light and heat on hydrogen peroxide and reduce the decomposition rate of sodium hypochlorite, so that the sodium hypochlorite disinfectant shows better stabi
