Phospholipids are amphiphilic. Phospholipids can self-assemble. The major driving force for this property is the hydrophobic effect that repels the lipid chains from water to form micelles or liposomes. The hydrophobic core of the lipid bilayer prevents the diffusion of hydrophilic solutes across it. sweat site
