Abstract
The present invention relates to a process for preparing a liquid silicate carbonate antiseptic agent. According to the present invention, the liquid silicate carbonate antiseptic agent is prepared by the process which comprises a step of dissolving 80-120 g of a silicate in 1 l of purified hot water at 70-90° C. until the silicate is completely ionized; a step of homogeneously emulsifying the mixture by adding 8-15 g of a emulsifier; and a step of stabilizing the resulting mixture by adding sodium carbonate (Na2CO3) and potassium carbonate (K2CO3) as carbonates in an amount of 45-80 g, respectively, and stirring the mixture. The liquid silicate carbonate antiseptic agent according to the present invention is characterized by the fact that in preparing the carbonate in a saturation state with sodium carbonate and potassium carbonate, the saturated carbonate is stabilized in aqueous solution by the addition of an effective amount of silicate and emulsifier and the heat treatment, and it has a broad disinfecting and biocidal effects on viruses, gram-positive bacteria and gram-negative bacteria even at a relatively low carbonate concentration and can maintain a sustained biocidal …
