These materials are available in anionic, non-ionic and cationic types in the market and due to their unique properties, they are used in various industries such as detergents, agriculture, etc. For information on the prices of different types of anionic surfactants and., Contact the relevant sales experts.
What is the definition of surfcant ?
There are substances that reduce the surface tension between two liquids or between a liquid and a solid. In general, any substance that affects surface tension can be considered a surfactant, but may also act as wetting, emulsifying, foaming, and dispersing agents. Surface activators play an important role in cleaning, wetting, dispersing, emulsifying, foaming and foaming in many industries and products.
Appearance of surfactants
These products include paints, emulsion adhesives, inks, disinfectants, shampoos, toothpastes, fire extinguishers, detergents, insecticides, cleaning recycled paper and more using's. In the aqueous phase, these materials form compounds called micelles, which form the hydrophobic tails of the nucleus, and the hydrophilic heads are immersed around the liquid. In addition, other structures can be produced. Types of these structures are spherical micelles or lipid layers. there is different types of surfactant.
- Non-ionic surfactant
- Anionic surfactant
- Cationic surfactant
The word "surfactant" is a collection of words "Surface active agent". Surfactants are usually organic compounds that have hydrophobic groups (water repellents) that act as tails and tails, and hydrophilic groups (water absorbers) that act as heads, so they dissolve in proportion to the molecular structure of organic solvents and water. Reduce surface tension in the air-water or oil-water interface. The chemical structure of these materials often consists of a relatively long molecule with one hydrophobic end and the other end hydrophilic. The hydrophobic part of this material (a long hydrocarbon sequence) is compatible with the resin and moves in its direction, while the hydrophilic part is oriented outwards (towards the water phase) and by surrounding the resin, it makes it compatible with water. Surfactants are substances that can greatly change the surface energy between surfaces. The property of a surfactant is due to the dual character of its molecular structure, which means that they have both hydrophilic and hydrophobic groups. Surfactants play an important role in many practical applications and products, for example: detergents, coagulants (such as blood), emulsifiers (such as creams), inks, foams (such as shampoos), dispersants (separators). , Polymers (such as car tires) and ... Surfactants are usually divided into four groups by anion groups: anionic surfactant (negatively charged), cationic surfactant (positively charged), non-ionic surfactant (uncharged), and amphoteric (neutrally charged). Nonionic surfactants are uncharged in their head. If the charge is negative, we have anionic surfactant and if it is positive, we have cationic surfactant. Sometimes the head has both negative and positive charges, which is called amphoteric Many chemical compounds form wet floors and surfaces but are not classified as surfactants (such as methyl alcohol in aqueous solution). The main characteristic of a detergent is that it accumulates on the surface of the liquid more than inside the liquid. This phenomenon is called adsorption and occurs on our surfaces between liquid-solid, liquid-liquid and air-liquid. Surfactants are organic compounds that have hydrophobic groups (water repellents) that act as tails and tails, and hydrophilic groups (water absorbers) that act as heads, so they dissolve in proportion to the molecular structure of organic solvents and water, reducing tensile strength. Surfaces become air-water or oil-water at the interface.
