Mercury

3. Amphoteric surfactant
• It’s the surface active agent composed of both
anionic and cationic ions, the molecular structure of
which is similar to amino acid and the properties of
which in aqueous solution varies with pH.
• Under alkaline condition it presents
anionic properties;
• At isoelectric point it presents nonionic properties;
• Under acid condition it presents cationic properties;
• Can form internal salts inside the molecule;
• Low toxicity, easy biodegradation, fine effects of
rinsing, emusifying, anti-corrosive, disinfectant and
antistatic, etc.;
• High cost, low dosage, potential and promising
