Amphoteric Surfactants
Amphoteric surfactants are unique surface-active agents that can act as either anionic or cationic surfactants depending on the pH of the solution. These molecules contain both acidic (carboxyl or sulfonic) and basic (amine or quaternary ammonium) functional groups, giving them high versatility, mildness, and compatibility with other surfactants. Amphoteric surfactants are widely used in personal care, household cleaning, industrial applications, pharmaceuticals, and specialty formulations where low irritation and effective cleansing are critical. Common examples include Cocamidopropyl Betaine and Lauryl Betaine.
Basic Laundry Detergent
Basic Laundry Detergent is a cleaning agent formulated primarily for washing textiles such as clothes, linens, and other fabrics. It typically contains surfactants, builders, enzymes, and other additives that work synergistically to remove dirt, stains, and odors from fabrics.
