Embodiment 1

[0101] (A) component, (B) component, 50 g of ion-exchanged water, and an appropriate amount of alkaline pH adjuster (sodium carbonate) shown in Tables 1 to 5 were stirred and mixed in a 200 mL beaker for 20 minutes. Make the pH value at this time reach 8-12. Afterwards, an acidic pH regulator (citric acid) was used to adjust to the target pH to obtain a fungicide composition. The change with time of the concentration of the organic peracid at this time was measured. The concentration of organic peracids was determined by the following method. The results are shown in Tables 1-5.

[0123]Stir and mix in a 200 mL beaker with (A) component, (B) component, 50 g of ion-exchanged water, and an appropriate amount of alkaline pH regulator (sodium carbonate) shown in Tables 6 to 9 for 20 minutes. Make the pH value at this time reach 8-12. Afterwards, an acidic pH regulator (citric acid) was used to adjust to the target pH to obtain a fungicide composition. Using the obtained bactericide composition, the bactericidal effect was measured by the following method. The results are shown in Tables 6-9.

Embodiment 3

[0133] (A) component, (B) component, organic phosphonic acid (trade name: D イ Cuest 2010 (Solu-Siaji ヤ Pan Co., Ltd.) and alkaline pH adjuster were added with ion-exchanged water so that the total weight was 100 g. This was stirred and mixed in a 200 mL beaker for about 10 minutes. Make the pH value at this time reach 8-12. Thereafter, the acidic pH adjuster of the weight shown in Table 10 was quickly adjusted to the target pH, and ion-exchanged water was added to make the total amount 110 g. The concentration of the organic peracid and the concentration of hydrogen peroxide at this time (immediately after preparation) were measured, and the sterilizing aqueous solution about 30 minutes after the start of stirring was adjusted so that the concentration of the organic peracid was 3000 ppm, and the bactericidal effect was confirmed. In addition, although the method of measuring the concentration of hydrogen peroxide and the concentration of organic peracid is carried out acco...

Abstract

The invention provides a composition for production of a sterilizer having a water content of 1 to 25% by weight and comprising (A) an ester of a polyhydric alcohol and an organic acid having a hydrocarbon group which may have a hydroxyl group and (B1) hydrogen peroxide. From the composition, a sterilizer is obtained as an aqueous solution containing an organic peracid.

Description

technical field [0001] The present invention relates to a composition for producing a bactericide, a bactericide composition, and a sterilizing method. Moreover, this invention relates to the manufacturing method of the organic peracid used for a bactericide, a bleach, etc., and the manufacturing method of a bactericide composition. Background technique [0002] At present, various agents exhibiting effects such as bleaching, sterilization, and disinfection are known. In particular, hypochlorites such as sodium hypochlorite are mainly used as chlorine-based bactericides, and hydrogen peroxide and hydrogen peroxide in water are mainly used as oxygen-based bactericides. Sodium percarbonate, sodium perborate, etc. that produce hydrogen peroxide. However, these bactericides have various problems, for example, hypochlorite has the problem of corroding metals and the like and the problem of chlorine gas generation due to misuse, and hydrogen peroxide has the problem of high bacte...
