わしいという欠点を有している。[Problems to be Solved by the Invention] However, since benzalkonium chloride is water-soluble as it is, it dissolves and disappears in a short time. Further, the dissolution rate is greatly affected by changes in various conditions such as water temperature, water quality, and water amount. For this reason, in order to maintain sufficient effects for a certain period of time, it is necessary to divide the dose into small doses and administer it frequently.
It has the disadvantage that maintenance and management are troublesome, such as the need to strictly control various conditions.

。There is no particular limit to the amount of higher fatty acid ester added to benzalkonium chloride, and it is determined appropriately depending on the purpose of use, required characteristics, etc., but the amount of higher fatty acid ester added to benzalkonium chloride is Too little,
Good moldability and sustained release properties cannot be obtained. Conversely, if the amount of higher fatty acid ester added to benzalkonium chloride is too large, dissolution of penzalkonicum chloride may not proceed sufficiently. Therefore, in normal cases, the higher fatty acid ester is 0.0% relative to the resulting slime control agent.
01~50! It is preferable to add it in an amount of i%.
