    Surfactant

    Surfactant refers to the addition of a small amount of substance that can make the interface state of the solution system change significantly. Surfactants are divided into ionic surfactants (including cationic surfactants and anionic surfactants), nonionic surfactants, amphoteric surfactants, compound surfactants, other surfactants, etc. "Surfactant" on Echemi mainly supplies chemicals for surfactants.

    Cationic Surfactants

    Cationic surfactants are mainly nitrogen-containing organic amine derivatives. They only have good surface activity in acidic media; they tend to precipitate out and lose surface activity in alkaline media. Because its main uses are special uses such as bactericides, fiber softeners and antistatic agents, it is used in relatively small amounts compared to anionic and nonionic surfactants. "Cationic Surfactants" on Echemi mainly supplies chemicals for cationic surfactants.

    Non-ionic Surfactants

    Non-ionic surfactants are surfactants that contain ether groups that do not dissociate in aqueous solution as the main hydrophilic group in their molecules, and their surface activity is reflected by neutral molecules. Non-ionic surfactants can be divided into polyoxyethylene type, polyol type, alkanolamide type, polyether type, amine oxide type, etc. according to the structure of the hydrophilic group. "Non-ionic Surfactants" on Echemi mainly supplies chemicals for non-ionic surfactants.

    Anionic Surfactants

    Anionic surfactants are the products with the longest history, the largest output and the most varieties among surfactants. They are negatively charged surfactants that ionize in water and play a part in surface activity. Structurally, anionic surfactants are divided into four categories: carboxylates, sulfonates, sulfates and phosphates. "Anionic Surfactants" on Echemi mainly supplies chemicals for anionic surfactants.

    Amphoteric Surfactants

    Amphoteric surfactants are surfactants that contain both anionic hydrophilic groups and cationic hydrophilic groups in the same molecule. Amphoteric surfactants usually have good washing, dispersing, emulsifying, sterilizing, soft fiber and antistatic properties, and can be used as fabric finishing aids, dyeing aids, calcium soap dispersants, dry cleaning surfactants and metal corrosion inhibitor Wait. However, the price of this type of surfactant is more expensive, and the practical application range is smaller than other types of surfactants. "Amphoteric Surfactants" on Echemi mainly supplies chemicals for amphoteric surfactants.
