Confusion arises because the term “anionic” is also used in cosmetics, detergents, and non-construction products, leading to irrelevant search results. Industrial anionic bitumen emulsions are defined by residue content, particle charge, viscosity, and breaking behavior under road standards. Clarification requires filtering by technical standards, test methods, and application context such as road construction, cold mix, or slurry systems. Procurement documents should explicitly reference construction standards and exclude consumer-grade terminology.
