Lamellar gel networks are multiphase systems which form the basis of many cosmetic and pharmaceutical cream products, thanks to their superior stability compared to typical oil-in-water emulsions, and highly desirable rheological properties inferred by the interconnected structure. There has previously been considerable interest in the formulation of lamellar gel networks, but little interest has been given to the effects of processing conditions on the formation of the desired structure, or the possibility for process optimisation through understanding power consumption. The evolution of the microstructure of an incipient lamellar gel network during processing was investigated by varying the temperature, vane speed and time using a rheometer equipped with a four-bladed vane in cup geometry. Torque and vane speed measurements were recorded at 2 Hz for the duration of the experiment, from which apparent viscosity (taken at a reference shear rate of 200 s^-1) and power input were calculated. Samples were then characterised by yield stress and flow curve measurements to determine the impact of processing conditions on the final product microstructure. Increasing vane speed increased the maximum apparent viscosity achieved and yield stress of the sample, and reduced the time taken to reach the peak apparent viscosity. However, the increased power requirements from the higher vane speed were not counteracted by shorter processing times. Increasing the temperature reduced the rate of apparent viscosity increase but did not affect the yield stress of the final lamellar gel network, offering a reduction in power consumption due to a lower apparent viscosity for the majority of the process.

层状凝胶网络是多相体系，形成了许多化妆品和药用乳膏产品的基础，这是由于与典型的水包油型乳剂相比，它们具有出色的稳定性，并且由相互连接的结构推断出非常理想的流变性。以前，层状凝胶网络的配方引起了人们的极大兴趣，但是对于工艺条件对所需结构的形成的影响，或者通过了解功耗进行工艺优化的可能性，人们的兴趣却很少。通过使用配备有杯形几何形状的四叶叶片的流变仪，通过改变温度，叶片速度和时间来研究加工过程中初始层状凝胶网络的微观结构的演变。^-1）和功率输入。然后通过屈服应力和流动曲线测量来表征样品，以确定加工条件对最终产品微结构的影响。叶片速度的增加会增加所达到的最大表观粘度和样品的屈服应力，并缩短达到峰值表观粘度所需的时间。然而，更高的叶片速度所带来的更高的动力需求并未因较短的处理时间而抵消。温度升高降低了表观粘度的增加速率，但并未影响最终的层状凝胶网络的屈服应力，由于在大多数过程中表观粘度较低，从而降低了功耗。
