What Are Surfactants?
Surfactants, or surface-active agents, are compounds that lower the surface tension between two substances, such as liquids, solids, or gases. These versatile agents can be classified based on their charge, which allows for different functionalities in various applications:
- Anionic Surfactants: Negatively charged and effective in cleaning applications.
- Cationic Surfactants: Positively charged, often used in fabric softeners and disinfectants.
- Nonionic Surfactants: No charge, ideal for sensitive formulations.
- Amphoteric Surfactants: Can carry either a positive or negative charge depending on the pH, making them suitable for many applications.
Key Applications of Surfactants
Surfactants and their applications span various sectors. Here’s a closer look at some key uses:
