Problems solved by technology

However, according to the Material Safety Data Sheets (MSDS), sodium hydroxide may cause irritation through skin and eye contact, and since it is a toxic chemical, care must always be taken
In addition, sodium hydroxide is less effective against (combat) viruses such as foot-and-mouth disease, the causative virus of this international infectious veterinary disease

Embodiment

[0016] Embodiment: the preparation of liquid carbonate antiseptic

[0017] 100 g of sodium silicate was added to 1 L of hot pure water (maintained at 80° C.), and then thoroughly ionized by dissolving the sodium silicate therein by sufficiently mechanical stirring. 10 g of glycerin was added thereto to emulsify the mixture. Then add sodium carbonate (Na 2 CO 3 ) and potassium carbonate (K 2 CO 3 ) each 60 g, and the resulting mixture was stirred in order to obtain an antibacterial agent stable in aqueous solution.

[0018] test 1 : Virucidal activity against foot-and-mouth disease virus

[0019] The virucidal activity of the liquid carbonate antibacterial agent prepared according to Example 1 of the present invention was checked with FMDVO type virus as the virus of foot-and-mouth disease.

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 DEG 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 activity.

Description

field of invention [0001] The present invention relates to a method for preparing a liquid silicate carbonate antiseptic agent. More specifically, the present invention provides a method for preparing non-toxic, function-improved, high-concentration, liquid carbonate antibacterial agents, wherein when sodium carbonate and potassium carbonate are used to prepare saturated carbonate, the supersaturated carbonic acid The salt is stabilized in aqueous solution by addition of effective amounts of silicate and emulsifier and heat treatment. Background of the invention [0002] Sodium hydroxide, which is usually used as an alkaline antibacterial agent in the prior art, is highly corrosive. In order to exhibit an effective antiseptic effect, it is recommended to use a concentration of up to 2%. But according to the Material Safety Data Sheets (MSDS), sodium hydroxide can cause irritation through skin and eye contact, and because it is a toxic chemical, care mu...
