Application

Butyl lactate has been used:
  • in the preparation of solid lipid nanoparticles by a solvent emulsification–diffusion technique[1]
  • in the synthesis of nanoparticles of griseofulvin from water dilutable microemulsions by the solvent diffusion technique[2]
  • as cosurfactant on the preparation of microemulsions with anionic surfactant[3]
