Description

Disinfectant composition comprising fulvic acid {GERMICIDE COMPOSITION INCLUDING FULVIC ACID}

The present invention relates to a disinfectant composition comprising fulvic acid.

Chlorination means adding chlorine to water for the purpose of sterilization, algae, organic matter, iron, manganese, ammonia, and the like. Sterilization using chlorine can be carried out by gaseous chlorine (Cl ₂ ) passing through the cell membrane and destroying intracellular enzymes, and at the same time, hypochlorous acid (HClO, Hypochlorous acid) destroying the cell membrane and oxidizing the enzyme. have.

In general, chlorine disinfectants include chlorine dioxide (ClO ₂ ), sodium hypochlorite (NaOCl, Sodium hypochlorite), calcium hypochlorite (Ca(OCl) ₂ , Calcium hypochlorite), hypochlorous acid (HClO, Hypochlorous acid), etc. This can be used.

For example, in Korean Patent Registration No. 10-0737951, an aqueous solution having a pH of 6 to 7 containing hypochlorous acid and/or its alkali metal salt (A), a surfactant (B), and a pH adjuster (C) is used. It is disclosed for a liquid disinfectant composition having an effective chlorine concentration of 5 to 500 ppm in the aqueous solution.

However, in the case of hypochlorous acid (HOCL) disclosed in the registered patent, there is a problem harmful to the human body by generating a large amount of free residual chlorine, combined residual chlorine such as chloramine, and by-products such as trihalomethane (THM). It is classified as an orally toxic substance and its use is regulated for disinfectants for children.

Accordingly, in recent years, various attempts have been made to use chlorine dioxide instead of hypochlorous acid. Although such chlorine dioxide has the advantage that the occurrence of carcinogenic organochlorine compounds of trihalomethane (THM) is significantly less and it is not greatly influenced by pH, most disinfectant compositions using chlorine dioxide developed so far have a stable formulation. There was a problem that the sterilization effect and its persistence could not be maintained as expected.

On the other hand, although the demand for a composition having an effect of removing heavy metals at the same time as sterilization is increasing, development of a composition having an effect of removing heavy metals while using chlorine dioxide is insufficient at present.

Accordingly, the present applicant uses chlorine dioxide instead of hypochlorous acid, which generates a large amount of harmful substances, but has excellent formulation stability, sterilization effect, and durability thereof, and at the same time has heavy metal removal performance. By developing a composition, the present invention was completed.
