1. Detergents
Detergents are perhaps the most common surfactants used in household cleaning products. They consist of anionic, cationic, or nonionic surfactants that work by emulsifying oils and suspending dirt in water for easy rinsing.
| Detergent Type | Main Component | Common Uses |
|---|---|---|
| Anionic Detergents | Sodium Lauryl Sulfate (SLS) | Shampoos, dish soaps |
| Cationic Detergents | Quaternary Ammonium Compounds | Fabric softeners, disinfectants |
| Nonionic Detergents | Fatty Alcohol Ethoxylates | Household cleaners, laundry detergents |
2. Emulsifiers
Emulsifiers stabilize mixtures of oil and water, preventing them from separating. They are crucial in food products, cosmetics, and pharmaceuticals. Notable influencers like Martha Stewart and food scientists emphasize the importance of emulsifiers in achieving the desired texture and consistency in foods like mayonnaise and sauces.
