Abstract

Abstract Cosmetic compositions exhibiting effervescence comprise a cosmetic agent and a liquefied gas distributed therethrough. The liquefied gas is present in the compositions at pressure and temperature conditions at which it would normally exist only in the gaseous state. As the liquefied gas separates from the compositions, effervescence occurs.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 176 words
An effervescing cosmetic composition confined under pressure in an aerosol dispensing container, said cosmetic composition consisting essentially of (a) a liquefied gas having a boiling point of from about -50° F. to about 80° F. and an aqueous or alcoholic phase (b) containing a liquid cosmetic and being substantially free of an agent capable of emulsifying the liquefied gas (a) in said phase (b), said phase (b) being substantially non-soluble with (a) and being dispersible with (a) with agitation thereof, liquefied gas (a) having a density greater than (b) and the quantity of (a) being at least about 5 percent by weight in excess of the quantity required to propel (b) from said container, said cosmetic composition being characterized by effervescence when said aerosol container is agitated whereupon (a) is dispersed in (b), and, while (a) and (b) are interdispersed, discharging contents of the container as a liquid stream into a vessel, some of the dispersed liquefied gas (a) remaining dispersed and entrained as a liquid in said liquid stream after the contents leave the container.
Claim 2
Dependent Claim 176 words
An effervescing cosmetic composition confined under pressure in an aerosol dispensing container, said cosmetic composition consisting essentially of (a) a liquefied gas having a boiling point of from about -50° F. to about 80° F. and an aqueous or alcoholic phase (b) containing a liquid cosmetic and being substantially free of an agent capable of emulsifying the liquefied gas (a) in said phase (b), said phase (b) being substantially non-soluble with (a) and being dispersible with (a) with agitation thereof, liquefied gas (a) having a density greater than (b) and the quantity of (a) being at least about 5 percent by weight in excess of the quantity required to propel (b) from said container, said cosmetic composition being characterized by effervescence when said aerosol container is agitated whereupon (a) is dispersed in (b), and, while (a) and (b) are interdispersed, discharging contents of the container as a liquid stream into a vessel, some of the dispersed liquefied gas (a) remaining dispersed and entrained as a liquid in said liquid stream after the contents leave the container.
Claim 3
Dependent Claim 13 words
The composition of claim 1 containing about 32 percent by weight of octafluorocyclobutane.
Claim 4
Dependent Claim 16 words
A composition of claim 1, wherein the container is at a temperature below about 50° F.
Claim 5
Dependent Claim 11 words
A composition of claim 1, wherein the vessel contains a liquid.
Claim 6
Dependent Claim 13 words
A composition of claim 1, wherein the liquefied gas is octafluorocyclobutane or monochloropentafluoroethane.
Claim 7
Dependent Claim 12 words
A composition of claim 1, wherein the cosmetic is a bath oil.
Claim 8
Dependent Claim 13 words
A composition of claim 1, wherein the cosmetic is a foot bath preparation.
Claim 9
Dependent Claim 12 words
A composition of claim 1, wherein the cosmetic is a facial preparation.
Claim 10
Dependent Claim 12 words
A composition of claim 1 containing a mixture of said liquefied gases.
