Abstract

Abstract An improved aerosol spray starch formulation is prepared by combining a starch component, a polyhydric material, a nonionic surfactant and a mixture of boric acid and borax in an aqueous medium together with a normally gaseous liquefied propellant. The starch formulation provides after pressing an excellent starching effect, that is, stiffness without roughness, without flaking or aerosol clogging.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 155 words
An aerosol starch formulation for use in finishing laundered textile garments comprising from about 2 to about 10 parts by weight of a liquefied normally gaseous propellant and from about 98 to about 90 parts by weight of an aqueous starch composition consisting essentially of water and from about 2 to about 6 percent by weight starch, from about 0.05 to about 1.0 percent by weight of a polyhydric material which enhances the wetting and anti-clogging properties of the composition and is selected from the group of polymeric glycols of alkanes and olefins having from 2 to about 6 carbon atoms, from about 0.01 to about 0.5 percent by weight of a nonionic surfactant, from about 0.05 to about 0.15 percent by weight of boric acid and from about 0.2 to about 0.6 percent by weight of borax, said formulation having a substantially reduced tendency to flake when applied onto fabric which is then ironed.
Claim 2
Dependent Claim 155 words
An aerosol starch formulation for use in finishing laundered textile garments comprising from about 2 to about 10 parts by weight of a liquefied normally gaseous propellant and from about 98 to about 90 parts by weight of an aqueous starch composition consisting essentially of water and from about 2 to about 6 percent by weight starch, from about 0.05 to about 1.0 percent by weight of a polyhydric material which enhances the wetting and anti-clogging properties of the composition and is selected from the group of polymeric glycols of alkanes and olefins having from 2 to about 6 carbon atoms, from about 0.01 to about 0.5 percent by weight of a nonionic surfactant, from about 0.05 to about 0.15 percent by weight of boric acid and from about 0.2 to about 0.6 percent by weight of borax, said formulation having a substantially reduced tendency to flake when applied onto fabric which is then ironed.
Claim 3
Dependent Claim 20 words
The formulation of claim 1 wherein the ratio of borax to boric acid is from about 5:1 to about 3:1.
Claim 4
Dependent Claim 33 words
The formulation of claim 1 which further contains, as an anti-foaming agent, from about 0.25 to about 0.75 percent by weight of a dimethyl polysiloxane emulsion containing about 10% by weight of silicone.
Claim 5
Dependent Claim 32 words
The formulation of claim 1 which further contains, as an ironing aid, from about 0.1 to about 1.0% by weight of a dimethyl polysiloxane emulsion containing about 37% by weight of silicone.
Claim 6
Dependent Claim 24 words
The formulation of claim 1 wherein said starch is a low viscosity starch derivative chosen from the group consisting of propoxylated and ethoxylated starches.

Dependent Claim 137 words
An aerosol starch formulation for use in finishing laundered textile garments comprising about 6 parts by weight of a liquefied isobutane propellant and about 94 parts by weight of an aqueous starch formulation consisting essentially of about water and 4 percent by weight of an ethoxylated corn starch, about 0.2 percent by weight of polyethylene glycol having a molecular weight of about 6,000, about 0.05 percent of octylphenoxy polyethoxy ethanol having about 9 to 10 oxyethylene groups per molecule, about 0.4 percent by weight of borax, about 0.1 percent by weight of boric acid, about 0.5 percent of a dimethyl polysiloxane emulsion containing about 10% silicone and about 0.5 percent of a dimethyl polysiloxane emulsion containing about 37% silicone, said formulation having a substantially reduced tendency to flake when applied to a fabric which is then ironed.
Claim 10
Dependent Claim 137 words
An aerosol starch formulation for use in finishing laundered textile garments comprising about 6 parts by weight of a liquefied isobutane propellant and about 94 parts by weight of an aqueous starch formulation consisting essentially of about water and 4 percent by weight of an ethoxylated corn starch, about 0.2 percent by weight of polyethylene glycol having a molecular weight of about 6,000, about 0.05 percent of octylphenoxy polyethoxy ethanol having about 9 to 10 oxyethylene groups per molecule, about 0.4 percent by weight of borax, about 0.1 percent by weight of boric acid, about 0.5 percent of a dimethyl polysiloxane emulsion containing about 10% silicone and about 0.5 percent of a dimethyl polysiloxane emulsion containing about 37% silicone, said formulation having a substantially reduced tendency to flake when applied to a fabric which is then ironed.
