Abstract

The present disclosure relates to, inter alia, a formulation in a package, the formulation comprises one or more active agents and is co-mingled with a whipping agent prior to being filled under pressure into the package. The whipping agent is added in sufficient amounts to be dispersed in the formulation. The pressurized package is under sufficient pressure suitable to maintain the whipping agent dispersed in the formulation; and the pressurized package is under sufficient pressure to expel the formulation as a whipped formulation upon application of external force on the formulation in the package.

First claim

1 . A formulation expelled from a pressurized package, the formulation comprising one or more skincare active agents, one or more of which being one or more solid ingredient(s); wherein said formulation is made by:
(i) blending the formulation comprising an amount of a whipping agent and said one or more skincare active agents; and (ii) rapidly mixing said formulation with a series of infusion gas injector ports controlling the whipping agent pressure and rate of flow of the formulation, in a high shear, continuous-flow, high-pressure whipping head, pressurized under controlled temperature, rate of flow, and pressure, saturating the whipping agent into the formulation; wherein said pressurized package is under sufficient pressure suitable to maintain the whipping agent dispersed in the formulation; and wherein said pressurized package is under sufficient pressure to expel said formulation as a whipped formulation upon application of external force on said formulation in said package; wherein said whipping agent is methane, ethane, butane, pentanes, propane, isobutene, N-butane, 1,1-Difluoroethane, hydrocarbons, dimethyl ether, 1,3,3,3-tetrafluoropropene, 1,1,1,2-tetrafluoroethane, or a combination thereof; wherein said whipped formulation is a reduced density gas emulsion with a multitude of gas microbubbles continuously distributed throughout the whipped formulation; wherein said one or more solid ingredient(s) are about 10% w/w to about 60% w/w of said formulation.

2 . The formulation of claim 1 , wherein said package maintains at least a minimal amount of pressure until substantially all the formulation in the package is expelled as a whipped formulation.

3 . The formulation of claim 1 , wherein said package comprises a pressure generating and maintaining component, wherein said component comprises one or more gas and/or liquid propellants which are not co-mingled with the formulation.

4 . The formulation of claim 1 , comprising less than 20% water.

5 . (canceled)

6 . The formulation of claim 1 , wherein said package is a bag on valve (BOV) pressurized assembly, comprising a two-way fill and dispensing valve, an attached internal high barrier bag affixed to said valve, and rigid container capable of holding positive pressure, affixed to the valve.

7 . The formulation of claim 6 , wherein said container is glass, barrier resin, metal/alloy, or another material capable of holding positive pressure.

8 . The formulation of claim 6 , wherein the BOV pressurized assembly dispenses the formulation in a metered dispensing system.

9 . The formulation of claim 1 , wherein said formulation is readily spreadable and spread evenly after the formulation is expelled from the package.

10 . (canceled)

11 . The formulation of claim 1 , wherein said formulation comprises solid ingredient between about 10-85% w/w.

12 . The formulation of claim 11 , wherein said solid ingredient comprises zinc oxide.

13 - 17 . (canceled)

18 . A pressurized package comprising a whippable formulation, the formulation comprises one or more skincare active agents, one or more of which being one or more solid ingredient(s); wherein said formulation is made by:
(i) blending the formulation comprising an amount of a whipping agent and said one or more skincare active agents; and (ii) rapidly mixing said formulation with a series of infusion gas injector ports controlling the whipping agent pressure and rate of flow of the formulation, in a high shear, continuous-flow, high-pressure whipping head, pressurized under controlled temperature, rate of flow, and pressure, saturating the whipping agent into the formulation; wherein said pressurized package is under sufficient pressure suitable to maintain the whipping agent dispersed in the formulation; and wherein said pressurized package is under sufficient pressure to expel said formulation as a whipped formulation upon application of external force on said formulation in said package; wherein said whipping agent is methane, ethane, butane, pentanes, propane, isobutene, N-butane, 1,1-Difluoroethane, hydrocarbons, dimethyl ether, 1,3,3,3-tetrafluoropropene, 1,1,1,2-tetrafluoroethane, or a combination thereof; wherein said whipped formulation is a reduced density gas emulsion with a multitude of gas microbubbles continuously distributed throughout the whipped formulation; wherein said one or more solid ingredient(s) are about 10% w/w to about 60% w/w of said formulation.

19 . The package of claim 18 , wherein said package maintains at least a minimal amount of pressure until substantially all the formulation in the package is expelled as a whipped formulation.

20 . The package of claim 18 , wherein said package comprises a pressure generating and maintaining component, wherein said component comprises one or more second gas and/or liquid propellants which are not co-mingled with the formulation.

21 . The package of claim 18 , wherein said package is a bag on valve (BOV) pressurized assembly, comprising a two-way fill/dispensing valve, an attached internal high barrier bag affixed to said valve, and rigid container capable of holding positive pressure, affixed to the valve.

22 . The package of claim 18 , wherein said formulation is readily spreadable and spread evenly after the formulation is expelled from the package, after being expelled from the package.

23 - 24 . (canceled)

25 . The package of claim 18 , wherein said solid ingredients, comprises zinc oxide.

26 . (canceled)

27 . The package of claim 21 , wherein the BOV pressurized assembly dispenses the formulation in a metered dispensing system.

28 . (canceled)

29 . The package of claim 25 , wherein said zinc oxide is from between about 10% w/w to about 40% w/w of said formulation.

30 . The formulation of claim 1 , wherein said solid comprises zinc oxide, titanium dioxide, wax, inorganic clay, minerals, microcapsules, or a mixture thereof.

31 . The formulation of claim 30 , wherein said solid comprises wax.

32 . The package of claim 18 , wherein said solid comprises zinc oxide, titanium dioxide, wax, inorganic clay, minerals, microcapsules, or a mixture thereof.

33 . The package of claim 32 , wherein said solid comprises wax.
