Abstract
Abstract A method of treating clothing articles with a fabric softener in a clothes dryer is disclosed, which comprises contacting the clothing articles with a foam containing said fabric softener. Also, fabric softener-containing compositions are disclosed which provide a stable, substantially form-sustaining, easily distributable foam when dispensed from an aerosol container, said compositions comprising by weight of the total composition (a) from about 1.0 to 30.0 percent of a fabric softener, (b) from about 50.0 to 94.0 percent of a solubilizer, and (c) from about 5.0 to 25.0 percent of a propellant, and wherein the solubilizer includes water in an amount comprising at least 40 percent of the total composition.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
98 words
A pressurized, self-propellant composition suitable to be dispensed from an aerosol container for use in a clothes dryer comprising, by weight of the total composition (a) from about 1.0 to 30.0 percent of a fabric softener, (b) from about 50.0 to 94.0 percent of a solubilizer, and (c) from about 5.0 to 25.0 percent of a propellant, and wherein the solubilizer includes water in an amount comprising at least 40.0 percent of the total composition, said (a), (b) and (c) providing a stable, substantially form-sustaining, substantially non-penetrating, surface adherent, easily distributable foam when dispensed from said aerosol container.
Claim 2
Dependent Claim
98 words
A pressurized, self-propellant composition suitable to be dispensed from an aerosol container for use in a clothes dryer comprising, by weight of the total composition (a) from about 1.0 to 30.0 percent of a fabric softener, (b) from about 50.0 to 94.0 percent of a solubilizer, and (c) from about 5.0 to 25.0 percent of a propellant, and wherein the solubilizer includes water in an amount comprising at least 40.0 percent of the total composition, said (a), (b) and (c) providing a stable, substantially form-sustaining, substantially non-penetrating, surface adherent, easily distributable foam when dispensed from said aerosol container.
Claim 3
Dependent Claim
29 words
The composition of claim 1 wherein (a) comprises 3.0 to 15.0 percent fabric softener, (b) comprises 65.0 to 90.0 percent solubilizer and the balance of the composition is propellant.
Claim 4
Dependent Claim
40 words
The composition of claim 1, wherein the solubilizer includes water in an amount comprising at least 65.0 percent of the total composition and the propellant is a member selected from the group consisting of dichlorofluoromethane and dichlorotetrafluoroethane and mixtures thereof.
Claim 5
Dependent Claim
23 words
The composition of claim 1, wherein said foam is stable, substantially form-sustaining, substantially non-penetrating and surface adherent for at least about thirty seconds.
Claim 6
Dependent Claim
29 words
The composition of claim 1, comprising 5.0 percent of a fabric softener, 81.5 percent water, 3.5 percent isopropyl alcohol and the balance a 57:43 mixture of dichlorodifluoromethane and dichlorotetrafluoroethane.
