Amphoteric surfactants are surfactants that contain both anionic and cationic hydrophilic groups in the same molecule. The greatest characteristic is that it gives and receives protons. In use they have the following characteristics: excellent softness, smoothness and antistatic properties for fabrics, some bactericidal and mould inhibiting properties, good emulsification and dispersibility.
Different amphoteric surfactants produced by the amphoteric surfactant manufacturer, such as C12-1 alkyl betaine (cocoamido propil betaina) and amine oxide, are often added to modern liquid dishwashing detergents due to their excellent foaming properties and mildness to the skin. They are often used to partially replace the anionic surfactants in formulations to reduce the irritation of anionic surfactant systems.
When the anionic surfactants in a formulation are partially replaced by these specific amphoteric surfactants, the skin gentleness is improved, not only because of the APG content in the formulation, but also because of the micelle blend formed by the amphoteric and anionic surfactants effectively removes the "toxic" properties of the anionic surfactants produced in the surfactant factories. The product is available in the form of a jelly dishwashing detergent. There is a jelly-like dishwashing detergent formulation that is gentle on the skin and has good foaming properties. The main active ingredient is a non-ionic surfactant, the remainder being anionic and amphoteric surfactants. The formulation is 7% ammonium lauryl sulphate, 7% cocamidopropyl betaine, 19% C12~5 alkyl polyoxyethylene (7)ether and the rest is water.
