SCIENTIFIC ANALYSIS

// Evidence: Solvents dissolve, dilute, or disperse other ingredients creating homogeneous solutions. Water is universal solvent for hydrophilic ingredients. Organic solvents include ethanol (dissolves fragrances, some actives), propylene glycol, and glycerin. Selection based on polarity matching between solvent and solute. Mechanism involves disrupting intermolecular forces in solute and surrounding with solvent molecules. Critical for maintaining ingredient solubility and product stability.
