Abstract

Emulsion stability is one of the key parameters in cosmetic formulation because it is directly related to product quality and consistency during storage. In Carbopol-based emulsion systems, the mixing process plays a major role in forming the gel structure and in the rheological properties of the final product. This study aims to examine the effect of mixing-speed variation on the viscosity and stability of a Carbopol system neutralized using NaOH. The mixing process was carried out at speeds of 1000, 1100, and 1200 rpm for 10 minutes, with a relatively constant Carbopol concentration. The observed parameters included changes in pH and emulsion viscosity, measured using a viscometer. The results show that all samples met the company’s pH and viscosity standards, with a mixing speed of 1100 rpm producing the highest viscosity value. These findings indicate that setting the appropriate mixing speed is essential for obtaining optimal emulsion stability in Carbopol-based cosmetic formulations.
