Surfactants are fascinating molecules with dual properties that allow them to interact with water and oil, making them versatile in various applications, including skincare, cleaning products, and industrial processes. Their ability to reduce surface tension and create stable mixtures between different substances is critical to their effectiveness in these diverse applications.
Common types of surfactants used in skincare include:
- Anionic surfactants have a negatively charged hydrophilic head and are commonly found in cleansing products like soaps and facial cleansers.
- Cationic surfactants have a positively charged hydrophilic head and are often used in hair conditioners and fabric softeners.
- Nonionic surfactants these do not have a charged head and are generally milder and less irritating, making them suitable for sensitive skin.
