Amino acid type amphoteric surfactants belong to green chemicals and have been used more and more extensively to many fields including medical treatment(such as solubilizer,sterilization and disinfection),high-end personal care(such as shampoo,facial mask,infant skin care product),silk dyeing and finishing,leather treatment,mineral flotation,oil exploitation,etc.Greases from natural products such as castor oil,tung oil,palm oil,etc.are treated by the processes of hydrolysis,amidation,sulfonation as depicted in Fig.1 and then are translated into the aim product,amino sulfonate amphoteric surfactants.The surfactant molecules contain a sulfonic acid group and at least two amino groups.Also,the sulfonic acid group and these amino group can locate in the main chain of surfactant,or they or one of them can act as the side chain,all of which lie on the need for the properties of surfactant.The type of surfactants are characteristic of readily biodegradation,low toxicity,low irritation to skin,benign softness,exquisite foam,antibacterial property,corrosion inhibition,better compatibility,etc.So far,the related outcomes about the type of surfactants include 5 patents for invention(3 of which have been authorized),more than 20 papers collected by SCI(which have been released in AIChE Journal,J.Ind.Eng.Chem.,J.Taiwan Inst.Chem.E.,etc.),and 3 science and technology awards at ministerial and provincial-level.
