Find Your Surfactant.

Aug. 01, 2022

Surfactants, which are so relevant to the life of human society. Surfactants are diverse and have a large family. (Come to SANCOLO CHEMICAL to find the surfactant you need and its prices)


What are surfactants?

Surfactants cause a significant change in the surface interface state of an aqueous solution system. They are generally made up of two parts, one lipophilic and the other hydrophilic. They are both oil- and water-soluble, a special structure known as the "amphiphilic structure", which is why surfactants are also called "amphiphilic molecules" and can be called surface active agent or surfactant.


Different types of surfactants.

Surfactants are known as "industrial monosodium glutamate" and are indispensable chemical auxiliaries in many industrial processes, with small dosages and large benefits. They are used everywhere in the textile, pharmaceutical, cosmetic, food, shipbuilding, civil engineering, mining and detergent sectors. In particular, they are the most important active ingredient in household products, producing bubbles and achieving unexpected effects in terms of stain removal, wetting, sterilisation and solubilisation.




Soap-based surfactants

Around 2500 BC, a royal cook of the ancient Egyptian pharaohs once accidentally spilled a pot of suet into the charcoal ashes. When he threw away the suet-soaked charcoal ashes and washed his hands, he found that they came out perfectly clean. When he washed his hands after throwing away the ashes, he found that they were very clean. When Pharaoh learned of this, he had it copied and this was the prototype of sheep's oil soap. Soap-based surfactants are classified as anionic surfactants, the oldest and most prolific and diverse group of active agents, from soap to Turkish red oil to sodium alkyl benzene sulfonate. Their greatest contribution has been to foaming and washing.


Cationic surfactants

Cationic surfactants are not very old, but the number of these surfactants and the demand for them is growing rapidly every year, and they are used as biocides, fabric softeners and antistatic agents. For example, quaternary ammonium-based cationic surfactants are added to everyday products such as shampoos, hand soaps and band-aids to kill bacteria. Generally speaking, most cationic surfactants are derivatives of organic nitrogen compounds with the positive ionic charge carried by nitrogen atoms, while some newer cationic surfactants have the positive ionic charge carried by atoms such as phosphorus, sulphur, iodine and arsenic. According to the chemical structure of cationic surfactants, they can be divided into four main categories: amine salts, quaternary ammonium salts, heterocyclic salts and lozenges




Non-ionic surfactants

Non-ionic surfactants do not ionise in aqueous solutions and their hydrophilic part is mostly made up of a certain number of oxygen-containing groups (generally ether groups and hydroxyl groups). This is what makes non-ionic surfactants superior to ionic surfactants in certain respects, such as high stability, because they are not ionic in solution, they are less susceptible to strong electrolyte inorganic salts and less susceptible to pH changes, have good resistance to hard water, possess low foaming characteristics, and are harmonious and compatible with other types of surfactants. Non-ionic surfactants are suitable for use as special detergents, giving full play to their multiple properties of dispersion, emulsification, foaming, wetting and solubilisation
