SCIENTIFIC ANALYSIS
// Evidence: Viscosity controlling ingredients modify product flow characteristics through thickening or thinning. Thickeners include natural gums (xanthan, guar), synthetic polymers (carbomers, acrylates), and inorganic thickeners (silica, clays). Mechanism varies: polymer chain entanglement, hydrogen bonding networks, particle association, or swelling. Rheology modifiers create desired texture, prevent separation, control application properties, and affect sensory perception. Can produce Newtonian (constant viscosity) or non-Newtonian (shear-thinning, thixotropic) flow behavior.
