ABSTRACT
The processing of liquids in industrial applications is typically accompanied by a wide range of physicochemical, biological, and mechanical phenomena. A detailed examination of these processes enables more effective control and optimization of the technological cycle. In particular, the rheological behavior of cosmetic and pharmaceutical fluids plays a crucial role in operations such as production, filling, packaging, and storage. The efficiency of these operations, the design of processing equipment, and the overall quality of the end products are strongly influenced by the flow properties of the materials being handled. This study investigates methods for determining the viscosity of liquids using a rotational viscometer, with a particular focus on
essential oils such as rose, lavender, and peppermint. Measurements were carried out with a Thermo Scientific HAAKE MARS iQ rheometer with air-bearing support to assess the influence of temperature on viscosity.
