Abstract

Claims (15)

1. A surfactant and its relevant salts of the following structure:

where R is chosen from, linear or branched, saturated or unsaturated, cyclic or acyclic alkyl from 1 to 8 carbons, R1 is chosen from —H, —CH 3 , —CH 2 CH 3 ; n is an integer greater than zero, A is chosen from —H, —CH 2 COOH, —CH 2 CH 2 COOH, —CH(CH 3 )COOH, —CH 2 CH 2 SO 3 − , —CH 2 CH 2 CH 2 SO 3 − , —CH 2 CH(OH)CH 2 SO 3 − , —CH 2 CH 2 CH 2 NCS 2 − , or —CH 2 CH(CH 3 )COOH, D is chosen from —CH 2 COOH, —CH 2 CH 2 COOH, —CH(CH 3 )COOH, —CH 2 CH 2 SO 3 − , —CH 2 CH 2 CH 2 SO 3 − , —CH 2 CH(OH)CH 2 SO 3 − , —CH 2 CH 2 CH 2 NCS 2 − , or —CH 2 CH(CH 3 )COOH.

2. The surfactant and its relevant salts of claim 1 where A=—H and D=—CH 2 CH(OH)CH 2 SO 3 − .

3. The surfactant and its relevant salts of claim 1 where A=—H and D=—CH 2 CH 2 COOH.

4. The surfactant and its relevant salts of claim 1 where A=D=—CH 2 CH 2 COOH.

5. The surfactant and its relevant salts of claim 1 where A=—H and D=—CH 2 CH(CH 3 )COOH.

6. The surfactant and its relevant salts of claim 1 where A=D=—CH 2 CH(CH 3 )COOH.

7. The surfactant and its relevant salts of claim 1 where A=—H and D=—CH 2 COOH.

8. The surfactant and its relevant salts of claim 1 where A=—H and D=—CH 2 CH 2 SO 3 − .

9. The surfactant and its relevant salts of claim 1 where A=—H and D=—CH 2 CH 2 CH 2 SO 3 − .

10. The surfactant and its relevant salts of claim 1 where A=—H and D=—CH 2 CH 2 CH 2 NCS 2 − .

11. The surfactant and its relevant salts of claim 1 where A=—H and D=—CH(CH 3 )COOH.

12. The surfactant and its relevant salts of claim 1 where A=D=—CH 2 COOH.

13. The surfactant and its relevant salts of claim 1 where A=D=—CH 2 CH 2 SO 3 − .

14. The surfactant and its relevant salts of claim 1 where A=D=—CH 2 CH 2 CH 2 SO 3 − .
