Sodium 4,6‐(2‐( N , N ‐bis‐ethylhexylamino)‐1,3,5‐triazine‐4,6‐yl‐amino) ethane sulfonate (IXC 8 ), Sodium 4,6‐(2‐( N , N ‐bis‐octylamino)‐1,3,5‐Triazine‐4,6‐yl‐amino) ethane sulfonate (XC 8 ) and 2,2′‐(6,6′‐(ethane‐1,2‐diylbis(azanediyl) bis(4‐(octylamino)‐1,3,5‐triazine‐6,2‐diyl)) bis(azanediyl))diethane sulfonate (C 8 ‐2‐C 8 ) were synthesized from cyanuric chloride. The surface activity and application properties of these surfactants (XC 8 , IXC 8 and C 8 ‐2‐C 8 ) were discussed. The values of CMC, γ CMC , pC 20 , Γ max , and A min calculated from surface tension measurement at 30 °C indicate that the surface activity of IXC 8 , which has two branched hydrophobic carbon chains, has lower γ CMC (26.8 mN m −1 ) than the other investigated surfactants and excellent wetting ability.
