Modular Emulsion-Based Product Differentiation
A micro-scale heterogeneous emulsion is provided. In some examples, the micro-scale heterogeneous emulsion can include at least two internal phases and an external phase. A method of producing a micro-scale heterogeneous emulsion is also disclosed herein. A method of providing a stable, custom cosmetic composition is also disclosed herein.
1 . A method of making a consumer product, the method comprising:
providing a first preliminary emulsion comprising a first preliminary internal phase and a first preliminary external phase, the first preliminary internal phase comprising a first polar solvent;
providing a second preliminary emulsion comprising a second preliminary internal phase and a second preliminary external phase, the second preliminary internal phase comprising a second polar solvent; and
combining the first preliminary emulsion with the second preliminary emulsion to create a final emulsion that is a micro-scale heterogeneous emulsion comprising
a first final internal phase;
a second final internal phase; and
a final external phase;
wherein the first final internal phase and the second final internal phase differ in chemical makeup; and
wherein the first final internal phase and the second final internal phase are each stabilized within the final external phase.
2 . The method of claim 1 , further comprising:
providing a third preliminary emulsion comprising a third preliminary internal phase and a third preliminary external phase, the third preliminary internal phase comprising a third polar solvent;
and combining the third preliminary emulsion with the first and second preliminary emulsions to create the final emulsion that is the micro-scale heterogeneous emulsion comprising
a first final internal phase;
a second final internal phase;
a third final internal phase; and
a final external phase;
wherein the first final internal phase, the second final internal phase, and the third internal phase each differ from each other in chemical makeup
wherein the first final internal phase, the second final internal phase, and the third internal phase are each stabilized within the final external phase.
3 . The method of claims 1 , wherein the first final internal phase comprises a first polar solvent and the second final internal phase comprises a second polar solvent.
4 . The method of claim 2 , wherein the first final internal phase comprises a first polar solvent, the second final internal phase comprises a second polar solvent, and the third final internal phase comprises a third polar solvent.
5 . The method of claim 1 , wherein the first and second polar solvents comprise water.
6 . The method of claim 1 , wherein the micro-scale heterogeneous emulsion emulsion is a high internal phase emulsion.
7 . The method of claim 1 , wherein the first final internal phase is formed from droplets having an overall size of 0.5 microns to 100 microns.
8 . The method of claim 1 , wherein the first final internal phase is formed from droplets having an overall size of 0.5 microns to 10 microns.
9 . The method of claim 3 , wherein the first polar solvent and the second polar solvent are the same solvent.
10 . The method of claim 3 , wherein the first polar solvent and the second polar solvent are a different solvent.
11 . The method of claim 3 , wherein the first polar solvent is aqueous and the second polar solvent is non-aqueous.
12 . The method of claim 1 , wherein the first final internal phase is structural and the second final internal phase is functional.
13 . The method of claim 1 , wherein the second final internal phase comprises one or more actives.
14 . The method of claim 1 , wherein the second final internal phase comprises at least one active not present in the first final internal phase.
15 . The method of claim 1 , wherein the final external phase comprises silicone.
16 . The method of claim 1 , wherein the first final internal phase and the second final internal phase are each stabilized within the final external phase by using at least one surfactant.
17 . The method of claim 1 , wherein the first final internal phase and the second final internal phase are each stabilized within the final external phase by using at least one functionally modified polymer.
18 . The method of claim 1 , wherein the micro-scale heterogeneous emulsion is a Pickering emulsion.
19 . The method of claim 1 , wherein the consumer product is either a cosmetic composition or a fabric care composition.
20 . The method of claim 2 , wherein the first final internal phase, the second final internal phase, and the third final internal phase are formed from droplets having an overall size of 0.5 microns to 100 microns.
