As component dosing in emulsions must be extremely precise, especially the emulsifier and the activator (e.g., HCl or NaOH), proper activation and temperature of the soap solution is important. Variation, even very slight, may have far reaching consequences. Soap solutions for typical cationic emulsions are usually in the 40ºC(104ºF) to 70ºC (160ºF) range.
