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 (21)

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

a first dispersed phase containing a silicone, wherein the silicone is provided as a non-emulsified silicone and wherein the silicone comprises:

b 1 ) an organopolysiloxane having at least two silicon-bonded alkenyl groups per molecule;

b 2 ) an organohydrogensiloxane having at least two SiH groups per molecule; and

b 3 ) a hydrosilylation catalyst; and

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

a first dispersed phase containing a silicone comprising an aminofunctional organopolysiloxane, wherein the silicone comprising the aminofunctional organopolysiloxane is provided as a non-emulsified silicone comprising the aminofunctional organopolysiloxane,

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.

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

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

5. A personal care composition comprising a bi-modal water continuous emulsion, 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,

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.

6. A personal care composition comprising a bi-modal water continuous emulsion, bi modal water continuous emulsion comprising at least 70 weight percent of:

a first dispersed phase containing a silicone comprising a polydimethylsiloxane, wherein the silicone comprising the polydimethylsiloxane is provided as a non-emulsified silicone comprising the polydimethylsiloxane,

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, and wherein the polydimethylsiloxane has a kinematic viscosity of from 100 to 600,000 mm 2 /s at 25° C.
