Abstract

Bi-modal water continuous emulsions are disclosed comprising at least 70 weight percent of a first dispersed phase containing a hydrophobic oil, wherein the hydrophobic oil is provided as a non-emulsified hydrophobic oil, a second dispersed phase containing a silicone, wherein the silicone is provided from a water continuous silicone emulsion containing at least one surfactant.

Claims (15)

1. A bi-modal water continuous emulsion comprising at least 70 weight percent of:

a first dispersed phase containing a hydrophobic oil, wherein the hydrophobic oil is provided as a non-emulsified hydrophobic oil and is a natural oil, a mineral oil, a hydrogenated polyisobutene, a fatty alcohol, an ester, a diester, or a triester,

a second dispersed phase containing a silicone, wherein the silicone is provided from a water continuous silicone emulsion containing at least one surfactant,

wherein the bi-modal water continuous emulsion contains less than 1 weight % cyclosiloxanes.

2. The bi-modal water continuous emulsion of claim 1 wherein the ester is isotridecyl isononanoate, PEG-4 diheptanoate, isostearyl neopentanoate, tridecyl neopentanoate, cetyl octanoate, cetyl palmitate, cetyl ricinoleate, cetyl stearate, cetyl myristate, coco-dicaprylate/caprate, decyl isostearate, isodecyl oleate, isodecyl neopentanoate, isohexyl neopentanoate, octyl palmitate, dioctyl malate, tridecyl octanoate, myristyl myristate, octododecanol, or mixtures of octyldodecanol, acetylated lanolin alcohol, cetyl acetate, isododecanol, polyglyceryl-3-diisostearate, or mixtures thereof.

3. The bi-modal water continuous emulsion of claim 1 wherein the natural oil is castor oil, lanolin and lanolin derivatives, triisocetyl citrate, sorbitan sesquioleate, C10-18 triglycerides, caprylic/capric/triglycerides, coconut oil, corn oil, cottonseed oil, glyceryl triacetyl hydroxystearate, glyceryl triacetyl ricinoleate, glyceryl trioctanoate, hydrogenated castor oil, linseed oil, mink oil, olive oil, palm oil, castor oil, illipe butter, rapeseed oil, soybean oil, sunflower seed oil, pine oil, tallow, tricaprin, trihydroxystearin, triisostearin, trilaurin, trilinolein, trimyristin, triolein, tripalmitin, tristearin, walnut oil, wheat germ oil, cholesterol, or mixtures thereof.

4. The bi-modal water continuous emulsion of claim 1 where the bi-modal water continuous emulsion has a viscosity less than 100,000 cP.

5. The bi-modal water continuous emulsion of claim 1 where the surfactant concentration in the bi-modal water continuous emulsion is less than 1 weight %.

6. The bi-modal water continuous emulsion of claim 1 wherein the bi-modal water continuous emulsion has a first dispersed phase with an average particle size of 0.2 to 100 micrometers, and a second dispersed phase with an average particle size of 0.2 to 100 micrometers.

7. A personal care composition comprising the bi-modal water continuous emulsion of claim 1 .

8. A coating composition comprising the bi-modal water continuous emulsion of claim 1 .

9. A personal care composition comprising the bi-modal water continuous emulsion of claim 2 .

10. A coating composition comprising the bi-modal water continuous emulsion of claim 2 .

11. A personal care composition comprising the bi-modal water continuous emulsion of claim 3 .

12. A coating composition comprising the bi-modal water continuous emulsion of claim 3 .
