"Surfactant", with both hydrophilic and hydrophobic properties, is a substance that tends to reduce the surface tension of a liquid in which it is dissolved. Reduced surface tension enables surfactant-based liquid to permeate through stains, oils, grease and dirt. In this way, the stubborn residues are dissolved and removed from the surface successfully. Due to this, surfactants are very common in various cleaning products.
Surfactants are widely used in detergents. They are added to laundry and dishwasher detergents, as well as many personal care products such as hair conditioners and shampoo. With the surface tension of water being reduced, surfactant cleaning agents are capable of penetrating the fabric, dissolving stubborn stains, leaving clothes bright and clean again. As for the neutral kitchen detergent, with the help of surfactants, foams are crated, fats and oils are dissolved, thus leaving the dirty dish sparkling clean.
According to the composition of the head group polarity, surfactants of hydrophilic and hydrophobic property, can be classified into four types: nonionic, anionic, cationic, amphoteric. There are some detergent surfactant examples. Personal care products with surfactants such as toothpaste and soap are able to cleanse the hair, skin, scalp and teeth more gently. While shaving creams with surfactants added does reduce the surface tension, and less friction is generated by the razor blade, giving a smoother shaving experience. Weiheng offers various cleaning agents with surfactants like Hexadecyl Trimethyl Ammonium Chloride. These are all commercially available.
Compared with nonfoaming and high foaming surfactants, low foaming surfactants are preferred by the industry for cleaning applications. The modified nonionic surfactants lower the foam capacity, most of which are in the form of liquid, in a water-diluted solution or 100% active. Low foaming surfactant cleaning agents by Weiheng are widely used as additional additives in dishwashing formulations, and are further applied in dairy cleaning bottle cleaning products.
