Surface active agent is usually divided into two categories:
Cattea surface active agent: It mainly reduces the surface tension of liquid through the action of positive ions and increases the contact ability of liquid and solid. Common cations surface active agents include hexisanelxyl tritenium bromide (CTAB), hexisanel trimethylsonium chloride (CTAC).
Non -ion surface active agent: It is a type of beacon -free surfactant, which is not easy to separate into ions. They change the surface nature of the liquid through the interaction of their hydrophobic group and hydrophilic group. Common non -ionic surfactants include throughylphenol ethoxylate, polyethylene glycol (PEG), etc.
In addition, there is an anionic surfactant and dual -sex surface active agent. The anion surface active agent includes sulfate, sulfonate, etc., and commonly referred to as sodium dodechl sulfate (SDS). The surfactant of the gender ions has the characteristics of cations and anion at the same time.
Different types of surfactants have different characteristics and application areas, which can be used in the fields of cleaner, detergent, emulsifier, lubricant, skin care products. When using surfactants in the product, you need to choose the appropriate ingredients according to specific needs and application scenarios.
