In experimental studies, it has been observed that the presence of sodium dodecyl sulfate (SDS) significantly increases kinetics hydrate formation and final water-to-hydrate conversion ratio. this study, we intend to understand molecular mechanism behind effect SDS on methane through dynamics simulation. Hydrate conditions similar laboratory experiments were chosen study growth in 1 wt % solution. We also investigate interactions with isolated molecules growth. It was hydrophobic tail part molecule favorably interacts growing surface may occupy partial cages while head groups remain exposed water.
