Dispersant is a type of surfactant commonly used to disperse solid particles or droplets and prevent them from regrouping. There are multiple options for the composition of dispersants, depending on the application field and the desired dispersion effect. The following are some common dispersant components:
Anionic surfactants: such as sodium dodecylbenzenesulfonate (SDBS), sulfates, etc. The main characteristic of these surfactants is their good dispersibility and stability, making them suitable for water-based systems.
Cationic surfactants: such as hexadecyltrimethylammonium bromide (CTAB), hexadecylamine, etc. These surfactants have good dispersion effects on certain specific particles and are suitable for organic solvent systems.
Non ionic surfactants: such as polyoxyethylene stearic alcohol ether (POE), polyoxyethylene octylphenol ether (Triton X-100), etc. These surfactants have wide applications in both water-based and organic solvent systems, and can effectively disperse various particles.
Natural polymers: such as gelatin, hydroxypropyl methyl cellulose (HPMC), etc. These natural polymers have good dispersibility and are environmentally friendly, commonly used in fields such as food and medicine.
Inorganic dispersants paa: such as nano silica (Aerosil), alumina, etc. These inorganic particles themselves have good dispersibility and can be directly used as dispersants.
Please note that different application fields and requirements may require different combinations of ingredients to achieve the best dispersion effect. In addition, when selecting and using dispersants, it is also necessary to consider relevant safety and environmental factors, and comply with corresponding legal regulations and standard requirements.
