Abstract
Abstract Aerosol solutions or emulsions useful in treating consumer''s goods especially fabrics to render them fire-retardant are formulated for packaging under pressure in a valved container; and comprise a freon-type solvent, a brominated or chlorinated phosphate or phosphite such as tris (2,3-dibromopropyl) phosphate and, if desired, a carrier such as a polyvinyl chloride latex.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
41 words
A fire retardant sprayable aerosol composition according to claim 1 in which the fire retardant material consists essentially of a brominated or chlorinated aliphatic phosphate or phosphite having 2 to 6 carbon atoms in each of its carbon to carbon chains.
Claim 2
Dependent Claim
20 words
A flame retardant aerosol composition according to claim 1 in which the fire retardant material is dissolved in the propellent.
Claim 3
Dependent Claim
33 words
A flame retardant sprayable aerosol composition according to claim 1 which also contains a carrier selected from the group consisting of polyvinyl acetate, polyvinyl chloride, polyvinyl alcohols, acrylic polymers and vinyl pyrrolidone polymers.
Claim 4
Dependent Claim
26 words
A flame retardant sprayable aerosol composition according to claim 1 in which the fire retardant material is tris (2,3-dibromopropyl) phosphate which is dissolved in the propellent.
Claim 5
Dependent Claim
25 words
A flame retardant sprayable aerosol composition according to claim 1 in which the fire retardant material is tris (2,3-dibromopropyl) phosphate and the propellent is dichloromonofluoromethane.
Claim 6
Dependent Claim
53 words
A flame retardant sprayable aerosol composition according to claim 1 in which the fire retardant material is tris (2,3-dibromopropyl) phosphate, which contains a carrier consisting essentially of polyviNyl acetate, and in which the propellent and common solvent for said fire retardant material and carrier consists essentially of a mixture of trichloromonofluoromethane and dichlorodifluoromethane.
Claim 7
Dependent Claim
25 words
A flame retardant sprayable aerosol composition according to claim 1 which contains an aqueous emulsion of the fire retardant material in addition to the propellent.
Claim 8
Dependent Claim
103 words
A flame retardant sprayable aerosol composition adapted when retained in a valved container to be pressurized and self-dispensing, which consists essentially of an aqueous emulsion having dissolved as a fire retardant material in its aqueous vehicle a member of the group consisting of an ammonium, amide, or quaternary ammonium compound selected from the group consisting of bromides, chlorides and phosphates, and having dispersed in said aqueous vehicle a brominated or chlorinated aliphatic phosphate or phosphite having 2-6 carbon atoms in each of its carbon to carbon chains; and as a propellent at least one aliphatic chlorofluoro hydrocarbon having 1 to 2 carbon atoms.
Claim 9
Dependent Claim
123 words
A flame retardant sprayable aerosol composition adapted when retained in a valved container to be pressurized and self-dispensing, which consists essentially of an aqueous emulsion having dissolved as a fire retardant material in its aqueous vehicle a member of the group consisting of an ammonium amide, or quaternary ammonium compound selected from the group consisting of bromides, chlorides and phosphates, and having dispersed in said aqueous vehicle, a brominated or chlorinated aliphatic phosphate or phosphite having 2-6 carbon atoms in each of its carbon to carbon chains; a carrier selected from the group consisting of polyvinyl acetate, polyvinyl chloride, polyvinyl alcohols, acrylic polymers, and vinyl pyrrolidone polymers; and as a propellent at least one aliphatic chlorofluoro hydrocarbon having 1 to 2 carbon atoms.
