| abstract |
The present invention concerns the use of an oil-in-water emulsion where the interior of oil droplets exhibit interfaces, between lipophilic domains and hydrophilic or amphiphilic domains, due to the presence of a lipophilic additive solubilized inside the oil droplets and which is used for delayed release of active elements such that the release of at least one active element, which has a octanol/water partitioning coefficient logP higher than −1, corresponds to a higher Tmax than the Tmax obtained for the simple reference oil-in-water emulsion where no lipophilic additive is used. |
