Surfactants
Surfactants, or surface-active agents, are compounds that lower the surface tension between two liquids, between a gas and a liquid, or between a liquid and a solid. They contain both hydrophobic (water-repellent) and hydrophilic (water-attracting) groups, allowing them to interact with both water and oils or fats. Types of Surfactants: Applications of Surfactants: Surfactants play…
