Active substances and surfactants are two common substances in the field of chemistry. They play an important role in different applications, but there are some obvious differences. This article will detail the differences between the two and explain their role in different applications.

actives generally refer to substances that act as catalysts or catalysts in chemical reactions. They can speed up the reaction rate and reduce the reaction energy, making it easier for the reaction to occur. The active substance can participate in the intermediate steps of the chemical reaction and will not be consumed by the reaction, so it can play a role of multiple catalysis in the reaction link. To give a practical example, enzymes are a common active substance that can accelerate metabolic processes in organisms, thereby promoting life activities.

Surfactants are a class of chemicals that lower the surface tension of liquids compared to actives. Surface tension is a characteristic of the surface of a liquid and refers to the result of the interaction between the molecules of the liquid. Surfactants can adsorb on the liquid surface, change the chemical properties of the surface, reduce the attraction between the liquid molecules, thereby reducing the tension of the liquid surface. This allows the surface of the liquid to flow more easily, which is suitable for use in some special applications, such as decontamination in detergents.

from a functional point of view, the active is more focused on promoting the rate and yield of the reaction, and they can be used many times without being exhausted. Surfactants, on the other hand, focus more on reducing surface tension and improving the fluidity and interfacial properties of liquids. Although the roles of the two are slightly different, there is overlap in some specific applications. For example, some actives are used as surfactants because they can both catalyze reactions and lower surface tension.

summarize, actives and surfactants are two different substances in the field of chemistry. The active substance is mainly used for catalytic reaction and can accelerate the reaction rate. Surfactants are mainly used to reduce the surface tension of liquids and improve fluidity and interfacial properties. Although the roles are slightly different, the two can cross-use in some specific applications. An in-depth understanding of the properties and applications of actives and surfactants is of great importance to both practitioners and researchers in the field of chemistry.
