What are iosurfactants and how do they work?
Iosurfactants, also known as ionic surfactants, are molecules that have both hydrophilic (water-attracting) and hydrophobic (non-polar) properties and therefore can be used as surfactants – compounds that lower the surface tension of liquids. They are molecular arrangements that are designed to behave like an oil droplet, with one side being hydrophilic (water-attracting) and the other side being hydrophobic (non-polar) or lipophilic (oil-attracting). When an iosurfactant is added to a solution, it will form a protective coating around particles (including droplets and powders), which reduces the surface tension and allows particles to combine better with other particles, suspend better in the solution, and more easily imparting properties needed in a wide range of products. This makes iosurfactants useful for a variety of applications, from medical treatments and cosmetics to food and industrial products.
