Oleate esters can be used as anti-wear and water resistance-improving agents in lubricants, or as lubricants and release agents in plastic processing, and also as additives in textiles, leather, and coatings. This dataset includes major raw and auxiliary materials, energy inputs, and waste outputs from the production process; however, infrastructure such as production equipment and facility construction is not included within the system boundary of the dataset. The life cycle inventory is compiled from data derived from multiple sources. The production process of oleate esters includes steps such as raw material preparation, transesterification, neutralization, separation and purification, dehydration, and distillation purification.
