Abstract: Improved conveyor lubricants are provided which are compatible with thermoplastic articles such as containers made of polyalkylene terephthalates. The lubricants are essentially free of oil and include a nonionic surfactant (e.g., a nonylphenol ethoxylates) dispersed in water where the surfactant has a molecular weight of at least about 1000 and contains at least about 12 ethylene oxide moieties therein. The surfactant should preferably comprise at least about 50% by weight of the non-aqueous components of lubricant concentrates and use dilutions. In use, the concentrates are diluted and sprayed or otherwise applied onto handling equipment for the thermoplastic articles. The use dilution surfactants of the invention give very advantageous lubricity ratio and crazing values, making them eminently suited for use with PET containers.
