Embodiment

[0029] Hereinafter, the present invention will be specifically described using formulation examples, examples, and comparative examples, but the present invention is not limited by these examples. "%" in Examples and comparative examples means "wt%".

[0030] The following examples are examples showing the synergistic effect of two antibacterial active substances of the preservative composition of the present invention. In addition, the following comparative examples are examples showing the antibacterial activity of the antiseptic composition alone and the combination of other isothiazoline compounds.

[0031] Preparation of Formulation 1-Formulation 6

preparation example 1

[0033] 5 g of 2-methyl-4,5-trimethylene-4-isothiazolin-3-one (hereinafter abbreviated as MTI) was weighed, and 93 g of purified water was added, stirred and dissolved. Next, add 2 g of 2-methyl-4-isothiazolin-3-one (Zone MT manufactured by Kaimei Coreia Co., Ltd., the active ingredient concentration is 50%, hereinafter referred to as MIT), and stir to obtain an MTI of 5.0%. , MIT is 1.0% preservative composition 1.

preparation example 2

[0035] Preservative composition 2 having MTI of 3.0% and MIT of 3.0% was obtained by the same method as formulation example 1.
