Abstract
Single phase preparations of hydrophilic species, in particular macromolecular compounds such as proteins or glycoproteins in a hydrophobic solvent such as an oil can be obtained by preparing a hydrophile/amphiphile array in which the hydrophilic head groups of the amphiphile are orientated towards the hydrophilic species and bringing the array into contact with the hydrophobic solvent. The preparations of the invention can be used alone or can be combined with an aqueous phase to form emulsions in which the hydrophilic species is present in the hydrophobic phase. The compositions of the present invention are versatile and have application in the pharmaceutical, food, cosmetic, chemical and agricultural industries.
