癸二酸二丁酯（DBS）是一个有机化学产物，是癸二酸的二丁基酯延伸物。其主要用途是作为塑化剂的塑料生产中，即醋酸丁酸纤维素，醋酸丙酸纤维素，乙基纤维素，聚乙烯醇缩丁醛，聚氯乙烯，聚苯乙烯，和许多合成橡胶（尤其是丁腈橡胶和氯丁橡胶）和其他塑料。它可以被用于食品包装行业中使用的塑料，医疗服务中的塑料，以及用于药物的应用，例如作为塑化剂的薄膜包衣囊剂、串珠、和颗粒剂。[2]，它也可以用来作为剃须洗剂中的润滑剂；非酒精饮料、冰淇淋、冰、糖果和烘烤食品中的调味料添加剂。它在低温下提供了优越的性能和良好的耐油性。其他名称包括Morflex，Kodaflex，polycizer，Proviplast1944和PX404。癸二酸二丁酯也被用来作为一个鱼雷组单元的脱敏剂的推进剂燃料名为奥托II。

Dibutyl sebacate (DBS) is an organic chemical, a dibutyl ester of sebacic acid. Its main use is as a plasticizer in production of plastics, namely cellulose acetate butyrate, cellulose acetate propionate, ethyl cellulose, polyvinyl butyral, polyvinyl chloride, polystyrene, and many synthetic rubbers (especially nitrile rubber and neoprene) and other plastics. It can be used for plastics in use in the food packaging industry, in plastics used for medical devices, and for pharmaceutical applications, e.g. as a plasticizer for film coating of tablets, beads, and granules. It is also used as a lubricant in shaving lotions, and a flavoring additive in non-alcoholic beverages, ice cream, ices, candy, and baked goods. It provides excellent compatibility with a range of plastic materials, superior properties at low temperatures, and good oil resistivity. Its other names include Morflex, Kodaflex, polycizer, Proviplast 1944 and PX 404. Dibutyl sebacate is also used as a desensitizer in Otto fuel II, a torpedo monopropellant.
