1. An oil-in-water emulsion composition comprising an oil phase and a water phase, wherein the composition comprises at least one amphiphlic polymer, wherein the at least one amphiphilic polymer is a polymer of natural origin modified by at least one fatty chain comprising 6 to 30 carbon atoms, wherein the oil phase is in the form of globules having a mean size ranging from 15 to 500 microns, wherein the oil phase is present in the composition in an amount of less than 3 5% by weight with respect to the total weight of the composition, and wherein the composition is translucent and has a transmission of light at a wavelength equal to 500 nm, through a sample with a thickness of 50 μm measured using a Carry 600 UV/visible spectrophotometer at a wavelength equal to 500 nm.
