已经将脂肪酶添加到洗涤剂中，以尝试开发用于基于脂肪酰胺的污渍的更环境友好和节能的产品。然而，需要更多的研究来提高含脂肪酶的洗涤剂的效率。在这项工作中，我们已经检查了所有的因素影响脂肪酶在洗涤剂配方中的性能，特别是用于硬表面清洁。几个问题，如热和流体动力学的稳定性，动力学方面，和表面活性剂的相容性，无论是在溶液中和在油/水界面，已得到解决，并已建立了最佳性能的条件。一些稳定剂在防止脂肪酶失活的作用也被认为是，并在洗涤条件下的脂肪酶失活的机制提供了一些见解。最后，在模拟原位清洁（CIP）系统的连续流动装置中进行的洗涤试验已经证明，在最佳条件下，在洗涤剂制剂中掺入脂肪酶后，表面活性剂剂量的减少是可能的。
Lipases have been added to detergents in an attempt to develop more environmentally friendly and energy efficient products for triglyceride-based stains. However, more research is needed to improve the efficiency of lipase-containing detergents. In this work we have examined all the factors affecting lipase performance in detergent formulations, particularly for hard surface cleaning. Several issues, such as thermal and hydrodynamic stability, kinetic aspects, and surfactant compatibility, both in solution and at the oil/water interface, have been addressed and the conditions for an optimal performance have been established. The role of some stabilizers in preventing lipase deactivation has also been considered, and some insight on the mechanisms of lipase deactivation under washing conditions is provided. Finally, washing tests conducted in a continuous flow device which simulates a clean-in-place (CIP) system have demonstrated that, under optimal conditions, a reduction of the surfactant dosage was possible upon the incorporation of lipases in detergent formulations.
