Abstract
A composition in a water-in-oil-in-water (W/O/W) emulsion is disclosed. The composition comprises: (a) a continuous aqueous phase, comprising HO; (b) an oil phase or an oil shell, dispersed in the continuous aqueous phase; and (c) a hydrophilic polymer, stabilizing an interface between the continuous aqueous phase and the oil phase or the oil shell to form the water-in-oil-in-water (W/O/W) emulsion. The oil phase or the oil shell comprises: (i) oil; (ii) an internal aqueous phase, dispersed within the oil or the oil shell; and (iii) a lipophilic sorbitan-polyester conjugate, stabilizing an interface between the oil and the inner aqueous phase to form a water-in-oil (W/O) emulsion. The lipophilic sorbitan-polyester conjugate comprises: (1) sorbitan; and (2) poly(lactide-co-ε-caprolactone) or polylactic acid (polylactide), conjugated to the sorbitan.
