HLB scale, solubilization and detergency The Hydrophilic-Lipophilic Balance (HLB) scale is essential in formulating effective pharmaceutical and cosmetic products. It measures the balance between the water-loving and oil-loving parts of a surfactant molecule, influencing solubilization and detergency. Solubilization enhances the solubility of poorly soluble compounds, improving drug efficacy and bioavailability. Detergency, on the other hand, … Read more
Surface active agents and Spreading coefficient Surface active agents, or surfactants, are compounds that reduce the surface tension between two phases, such as liquids, gases, or solids. These agents possess both hydrophilic (water-attracting) and hydrophobic (water-repelling) properties, allowing them to interact with different substances. Surfactants are widely used in various industries, including pharmaceuticals, cosmetics, and … Read more
