最近对废油处理产生影响的监管变化，以及一些氯化石蜡被认定为致癌物，表明尽管氯化石蜡具有有用的性质，但最终将成为工业润滑油中不可接受的成分。本文讨论了一种水基、非磺基氯化润滑剂的开发，以取代传统的油基磺基氯化润滑剂，并考察了新润滑剂的测试过程。讨论的开发协议和测试方法通常适用于任何传统金属加工或金属成型润滑剂的替代品的开发。

RECENT REGULATORY CHANGES AFFECTING THE DISPOSAL OF USED OILS, TOGETHER WITH THE IDENTIFICATION OF SOME CHLORINATED PARAFFINS AS CARCINOGENS, SUGGEST THAT CHLORINATED PARAFFINS, THEIR USEFUL PROPERTIES NOTWITHSTANDING, WILL EVENTUALLY BECOME UNACCEPTABLE AS INGREDIENTS IN INDUSTRIAL LUBRICANTS. THIS PAPER DISCUSSES THE DEVELOPMENT OF A WATER-BASED, NON-SULFO-CHLORINATED LUBRICANT TO REPLACE A CONVENTIONAL OIL-BASED SULFO- CHLORINATED LUBRICANT, AND EXAMINES THE TESTING PROCESS TO WHICH THE NEW LUBRICANT WAS SUBJECTED. THE DEVELOPMENT PROTOCOL AND TEST METHODS DISCUSSED ARE GENERALLY APPLICABLE TO THE DEVELOPMENT OF REPLACEMENTS FOR ANY CONVENTIONAL METAL WORKING OR METAL FORMING LUBRICANT.
