Patent ID: 8388985

Claim:
A process for preparing an oil-in-water emulsion, the process comprising mixing a lipidic phase with an aqueous phase by manual operation or using a low energy device, wherein the lipidic phase comprises: (i) an oil selected from the group consisting of mineral oils, hydrocarbons, vegetable oils, waxes, alcohols, fatty acids, mono-, di-, tri-acylglycerols, essential oils, flavouring oils, lipophilic vitamins, esters, neutraceuticals, terpins, terpenes, and mixtures thereof, and (ii) a lipophilic additive (LPA) or mixtures of lipophilic and hydrophilic additives, having a resulting HLB value (Hydrophilic-Lipophilic Balance) lower than about 10, wherein the LPA content in the lipidic phase is between 0.25 wt-% and 84 wt-%, wherein the aqueous phase contains an emulsifier or an emulsion stabilizer, and wherein the emsulsion forms oil droplets having a diameter in the range of 5 nm to hundreds of micrometers which droplets exhibit nano-sized self-assembled structures with hydrophilic domains having a diameter in the range of 0.5 to 200 nm due to the presence of the LPA in the lipidic phase.
