IN VITRO BIOFILM, AND EVALUATION METHOD OF ODOR-REMOVING EFFECT OF WASHING AGENT

摘要

PROBLEM TO BE SOLVED: To provide an in vitro biofilm as an evaluation model of biofilms formed in a laundry sink, and to provide an evaluation method of the odor-removing effect of a washing agent using this.SOLUTION: The invention provides an in vitro biofilm producing one or more kinds selected from the group consisting of a compound represented by a general formula (1), a compound represented by a general formula (2), and pyridine. In the formula (1), Ris an alkyl group, an alkenyl group, or a hydrogen atom; Ris an alkyl group, an alkenyl group, a hydrogen atom, or a hydroxy group; and X is a group containing a sulfur atom, or a carbonyl group. In the formula (2), R-Rare each independently an alkyl group, an alkenyl group, or a hydrogen atom; and Y is a group containing a nitrogen atom.SELECTED DRAWING: None
