Modern cleansing formulation prioritizes skin barrier preservation over aggressive foaming. Achieving this requires managing the critical micelle concentration (CMC) and surfactant geometry. This prevents the product from running off the
Advanced formulations utilize thixotropic flow behavior. A thixotropic fluid thins out under shear stress (like pumping a bottle or rubbing a cream onto the skin) but returns to its high-viscosity state when the stress is removed. This prevents the product from running off the skin during application. 5. Preservation Chemistry and Microbial Defenses cosmetic formulations an advanced guide book pdf
