The main differences come from the chemical system used to create charge and stability. Cationic emulsions usually involve acidified soap solutions and amine based emulsifiers, so MSDS may emphasize corrosivity risks, acid handling, and pH control hazards. Anionic emulsions may use different surfactants and pH ranges, often with lower acid handling emphasis. Both will cover bitumen hazards and spray exposure, but cationic MSDS often includes stricter guidance on chemical dosing, eyewash readiness, and compatibility warnings with alkaline materials.
