Interpretation
The term “Amphoteric surfactant” should be explained
Concept introduction
Surfactant are organic molecules which are amphiphilic in nature means they contain both hydrophobic (tails) groups as well as hydrophilic groups (head). In aqueous solution the head groups remain in solution whereas the tails may extent out of the aqueous phase. Based on the nature of the head group, surfactants are classified into three categories. When the head groups have no charge, it’s called non-ionic surfactant. If the head group has net positive charge (cationic
