The use of toxic petroleum‐based heavy oils is common in industrial processes. The cleaning of machines, equipment, and other surface covered in these oils is achieved with expensive products that are often also toxic and harmful to both the health of workers and the environment. The present paper proposes the development of a sustainable biodetergent made from plant‐based materials. Tests were performed to determine the properties of the biodetergent in terms of its surfactant and emulsifying capacities, stability, toxicity, and the removal of heavy oil from glass plates and metallic surfaces. The formulation was composed of a natural solvent (cottonseed oil), a plant‐based surfactant agent (saponin), and two natural stabilizers (carboxymethylcellulose and glycerine). The formulation was stable, nontoxic, and highly efficient, removing 100% of the heavy oil from glass and metallic surfaces. This solution developed in this study could be used in diverse industries with the need to clean machines and parts encrusted with oil and grease as well as the cleaning of floors covered with petroleum‐based residues. A preliminary analysis of the economic feasibility of using the detergent was carried out at a Brazilian power plant. Besides the reduction in environmental impact due to the use of a nontoxic, biodegradable product as well as the reduction in health risks to workers associated with toxic cleaning products, this new product can have a considerable impact on the market as an environmentally friendly solution.

用于清洁工业过程中产生的油性残留物的可生物降解的洗涤剂配方

在工业过程中通常使用有毒的石油基重油。用昂贵的产品清洁机器，设备和这些油中覆盖的其他表面，这些产品通常也对工人和环境的健康有毒有害。本文提出了一种由植物基材料制成的可持续生物洗涤剂的开发。进行了测试以确定生物洗涤剂的表面活性剂和乳化能力，稳定性，毒性以及从玻璃板和金属表面去除重油的性能。该配方由天然溶剂（棉籽油），植物基表面活性剂（皂素）和两种天然稳定剂（羧甲基纤维素和甘油）组成。该制剂稳定，无毒且高效，从玻璃和金属表面去除100％的重油。这项研究中开发的解决方案可用于需要清洁油脂覆盖的机器和零件以及清洁石油基残留物地板的各种行业。在巴西的一家发电厂对使用这种洗涤剂的经济可行性进行了初步分析。除了由于使用无毒，可生物降解的产品而减少对环境的影响以及与有毒清洁产品有关的对工人的健康风险的减少以外，这种新产品还可以作为对环境友好的解决方案对市场产生重大影响。这项研究中开发的解决方案可用于需要清洁油脂覆盖的机器和零件以及清洁石油基残留物地板的各种行业。在巴西的一家发电厂对使用这种洗涤剂的经济可行性进行了初步分析。除了由于使用无毒，可生物降解的产品而减少对环境的影响以及与有毒清洁产品有关的对工人的健康风险的减少以外，这种新产品还可以作为对环境友好的解决方案对市场产生重大影响。这项研究中开发的解决方案可用于需要清洁油脂覆盖的机器和零件以及清洁石油基残留物地板的各种行业。在巴西的一家发电厂对使用这种洗涤剂的经济可行性进行了初步分析。除了由于使用无毒，可生物降解的产品而减少对环境的影响以及与有毒清洁产品有关的对工人的健康风险的减少以外，这种新产品还可以作为对环境友好的解决方案对市场产生重大影响。
