Viscosity is a measure of a fluid's resistance to flow and reflects the internal friction within the fluid. Cosmetics, including emulsions and liquid products, are classified as fluids. From both practical and theoretical perspectives, viscosity has become one of the key physical properties and technical indicators in cosmetic formulation. Maintaining a specific viscosity is essential for product stability, and it also plays a significant role in the product’s appearance and user experience. Therefore, achieving the right balance in viscosity is crucial for high-quality cosmetic products.

Most cosmetics are non-Newtonian fluids, meaning their viscosity changes under different shear forces. This makes measuring and controlling viscosity an important challenge during the formulation and production process. The choice and concentration of emulsifiers significantly influence the viscosity of emulsions. Emulsifiers help reduce surface tension, promote dispersion, and stabilize the mixture. Their type, concentration, and characteristics directly affect the size and distribution of droplets in the emulsion, which in turn affects the overall viscosity.

Increasing the concentration of the emulsifier generally leads to smaller droplet sizes and higher viscosity. However, if the concentration becomes too high, it may cause wider droplet size distribution and lower viscosity. This delicate balance is essential in creating stable and effective cosmetic products. Proper emulsifier selection and control are vital for achieving the desired texture and performance in the final product.
