easy to form micelles at lower conc. conc is number of moles per unit v right? if mass increases (longer chain) then you need a smaller number of moles technically (crude explanation but works for this, i feel!)

More longer the hydrophobic chain more the repulsion and more the cohesion. So the molecules merge and precipitate out. @Say_miracle_shadow

@Ghostty Can you elaborate how there is more repulsion and more cohesion ? @iTeachChem Yes sir , Sir I think that seeing only the increase in mass and then less no. Of moles will be a good reference iff other parameters are assumed to be constant like volume , given mass ....

The hydrophobic part doesn't dissolve in water and stays away from it as it contains fatty acids(that's why it is called hydroPHOBIC). and cohesion is the property of bulk material, non polar attracts non polar. It has more to do with surface tension and contact angle thing. I advise you not to go to deep.
