ABSTRACT:
A lubricant composition for a resin conveyor, comprising specific (A) a nonionic surfactant and (B) water and, if necessary, (C) (a) a cationic surfactant and/or (b) an amphoteric surfactant, and a method for using same. Using a specific nonionic surfactant as the main component provides excellent washing ability, lubricating ability, and stability in storage. In particular, because excellent ability to prevent stress cracking is attained, the lubricant composition for a resin conveyor can be advantageously employed for transporting PET containers. Furthermore, adding a specific cationic surfactant makes it possible to obtain a lubricant composition for a resin conveyor also demonstrating an effect of inhibiting microorganism (fungi) generation, without degrading the various original performances (effects). Furthermore, a preferred method for using those lubricant compositions for resin conveyors is also provided.
