Biofilm formation inhibitor composition
A drug and a composition for inhibiting biofilm formation are provided. A biofilm formation inhibitor composition containing the following component (A): (A) at least one or more selected from compounds represented by Formula (1) to Formula (4): wherein R 1 to R 5 each represent an alkyl group or the like; EO represents an ethyleneoxy group; p represents an integer from 0 to 5; and m+n represents a number from 0 to 30, or a salt thereof; and (B) a surfactant.
1. A method of inhibiting biofilm formation, which method comprises:
contacting a biofilm formation inhibitor composition with microorganisms, wherein the biofilm formation inhibitor composition comprises the following component (A):
(A) at least one or more selected from compounds represented by Formula (1) and Formula (2) or a salt thereof:
wherein R 1 and R 2 , which are identical or different, each represents an alkyl group or an alkenyl group, which is a straight chain or branched chain having 8 to 14 carbon atoms; EO represents an ethyleneoxy group; p represents an integer from 1 to 5; and m and n are each an average number of added moles, with m+n being a number from 2 to 30; and
(B) a surfactant;
wherein the weight ratio of the component (A) and the component (B), (A)/(B), is not more than 2.
2. The method of inhibiting biofilm formation according to claim 1 , wherein the contact between the biofilm formation inhibitor composition and microorganisms is carried out continuously.
3. The method of inhibiting biofilm formation according to claim 1 ,
wherein the concentration by weight of the component (A) at the time of use of the biofilm formation inhibitor composition is 1 to 10,000 ppm.
4. The method according to claim 1 , wherein the component (B) surfactant is at least one or more selected from the group consisting of anionic surfactants, and nonionic surfactants other than the component (A).
