FAQ
Frequently Asked Questions
Not exactly. Soap is a type of surfactant and can act as a wetting agent, but many specialized wetting agents are synthetic chemicals designed for specific industrial applications where soap would be ineffective.
Yes, in informal gardening, a small amount of mild dish soap can act as a simple wetting agent to help water penetrate hydrophobic (water-repellent) soil, but commercial horticultural wetting agents are formulated to be safer for plants and soil biology.
Almost, but not perfectly. All wetting agents are surfactants, but not all surfactants are primarily used as wetting agents. Surfactants can also be used as detergents, emulsifiers, foaming agents, or dispersants, where wetting is not the main goal.
In laundry detergents (to help water wet fabrics), in eye drops (to help the solution spread across the eye), in inkjet printer inks (for even printing), and in shampoos (for better hair coverage).
