During iontophoresis, the infusion of a positive product is known as what?

The infusion of a positive product during iontophoresis is known as cataphoresis. In the context of iontophoresis, cataphoresis refers specifically to the movement of positively charged ions toward the negatively charged electrode, which allows for the application of certain products into the skin. This technique is often used in various skin treatments to enhance the delivery of active ingredients by leveraging electrical currents, making the absorption of beneficial substances more efficient.

Understanding iontophoresis also involves recognizing how different processes play a role in the movement of ions. For example, electroosmosis involves the movement of liquid, rather than ions, and electrophoresis pertains to the movement of particles in a fluid, typically under an electric field. Neutralization indicates a balancing action between positive and negative charges, rather than the specific infusion of a product. Therefore, in the context of delivering a positive product during iontophoresis, cataphoresis is the accurate term that describes this particular action.
