Described is composition containing a biliquid material, and methods and uses thereof.

The current invention concerns a method for preparing an emulsion comprising the steps: mixing a first phase and a second phase in a layer multiplier to produce a multilayered fluid structure, and collapsing said multilayered fluid structure, thereby dispersing the second phase in the first phase creating an emulsion. The current invention relates to a method for producing dispersions. The current invention also concerns the emulsions produced by said method. The current method also relates to polymer emulsions, particularly polyisobutene emulsions with a high content of polyisobutene.

A terpene composition, adapted at least for olfactory use, has one or more terpene materials. Furthermore, the terpene composition has one or more emulsifiers. The terpene composition also has a humectant. Finally, the terpene composition has a solvent. The one or more terpene materials are in a range of five to fifty percent of the terpene composition.

Nanoscale emulsions can be made by means of condensing a liquid vapor onto another liquid. The precise size, chemical composition, and density of emulsions may be controlled through varying the experimental parameters, such as surfactant concentration, time of condensation, humidity, and temperature.

A biliquid material includes an emulsion having a continuous liquid phase, a dispersed liquid phase, and a surface-stabilizing material, wherein: the dispersed liquid phase is immiscible with the continuous liquid phase; the dispersed liquid phase is in the form of a plurality of droplets in the continuous liquid phase; the surface-stabilizing material is soluble in at least one of the continuous liquid phase and the dispersed liquid phase and preferentially adsorbs at the surfaces of the plurality of droplets, wherein the surface-stabilizing material imparts a repulsive interaction between the plurality of droplets that inhibits coalescence of the plurality of droplets; and the biliquid material has a structurally-colored droplets structure, wherein the structurally-colored droplets structure yields one or more structural colors when illuminated with broad-spectrum light wherein the one or more structural colors arise from diffraction of the broad-spectrum light by the plurality of droplets.

Process for the preparation of a water-in-oil or oil-in-water nanoemulsion wherein the dispersed phase is distributed in the dispersing phase in the form of droplets having a diameter ranging from 1 to 500 nm, comprising: 1) the preparation of a homogeneous water/oil blend (I) characterized by an interface tension lower than 1 mN/m, comprising water in an amount of 30 to 70% by weight, at least two surface-active agents having a different HLB, selected from non-ionic, anionic, polymeric surface-active agents, said surface-active agents being present in such a quantity as to make the blend homogeneous; 2) the dilution of the blend (I) in a dispersing phase consisting of oil or water with the addition of a surface-active agent, selected from non-ionic, anionic, polymeric surface-active agents, the quantity of the dispersing phase and surface-active agent being such as to obtain a nanoemulsion having a HLB different from that of the blend (I).
