Abstract
Abstract A fabric-conditioning composition incorporated in an article used to condition fabrics in a laundry dryer. The fabric-conditioning composition carried on a sheet-like flexible substrate includes special fatty glyceride spreading agents to enhance uniform transfer of the conditioning agents to fabrics when tumbled therewith in a clothes dryer. The article is capable of effective conditioning fabrics without staining because of the spreading agents which aid in the uniform release of fabric-conditioners from the substrate at dryer operating temperatures, and aids in uniformly spreading the fabric-conditioners over the clothes being treated. The presently preferred fatty glyceride spreading agents comprise ethoxylated, propoxylated glycerol and mono- and diesters of hydrogenated tallow acids. These spreading agents are preferably used with a cationic quaternary ammonium fabric-conditioner, more particularly ditallow and dimethyl ammonium sulfate. Other fabric-conditioning materials which may be used include other cationic fabric-conditioners, nonionic and anionic surfactants, perfumes, brighteners, crisping agents, sizing materials and combinations of these. The preferred mode of use is in the clothes dryer, but the article may also be used in the washing machine, preferably in the rinse cycle.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
61 words
An improved fabric-conditioner article particularly adapted for use in a clothes dryer comprising a fabric-conditioning composition carried on a substrate, said fabric-conditioning composition comprising about 60-90% by weight of a cationic fabric-conditioner composition, about 3-40% by weight of ethoxylated, propoxylated glycerol and mono- and diesters of hydrogenated tallow acids, and about 3-15% by weight of a stearic acid type, nonionic surfactant.
Claim 2
Dependent Claim
61 words
An improved fabric-conditioner article particularly adapted for use in a clothes dryer comprising a fabric-conditioning composition carried on a substrate, said fabric-conditioning composition comprising about 60-90% by weight of a cationic fabric-conditioner composition, about 3-40% by weight of ethoxylated, propoxylated glycerol and mono- and diesters of hydrogenated tallow acids, and about 3-15% by weight of a stearic acid type, nonionic surfactant.
Claim 3
Dependent Claim
18 words
The fabric-conditioner article of claim 1, in which the cationic fabric-conditioner composition comprises ditallow dimethyl ammonium methyl sulfate.
Claim 4
Dependent Claim
61 words
The improved fabric-conditioner article of claim 1, in which the fabric-conditioner is carried on a sheet-like substrate which is impregnated with a stiffening agent selected from the group consisting of alkylated amino crosslinked resins and modified melamine formaldehyde resins which have a good water solubility, resist heat cracking and allow the sheet-like substrate to remain flexible at the dryer operating temperature.
Claim 5
Dependent Claim
125 words
An improved fabric-conditioner article particularly adapted for use in a clothes dryer comprising, in combination: a. a fibrous, sheet-like substrate material selected from the group consisting of cellulosic or non-cellulosic sheet materials and combinations thereof; b. a stiffening material applied to said substrate to impart stiffness and resilience to said substrate at temperatures in the range of 140°-205° F. (60°-96.1° C.) whereby folding of said substrate when said fabric-conditioner article is tumbled with clothes is minimized; and c. a fabric-conditioner composition carried on said substrate and adapted for transfer to fabrics-commingled therewith, said composition comprising about 60-90% by weight of a cationic quaternary ammonium compound and about 3-40% by weight of nonionic surfactant comprising ethoxylated, propoxylated glycerol and mono- and diesters of hydrogenated tallow acids.
Claim 6
Dependent Claim
125 words

Claim 8
Dependent Claim
22 words
The article of claim 5, in which the ditallow dimethyl ammonium methyl sulfate comprises about 75% by weight of said fabric-conditioner composition.
Claim 9
Dependent Claim
27 words
The article of claim 4, in which the ethoxylated, propoxylated glycerol mono- and diesters of hydrogenated tallow acid comprise about 3-15% by weight of said fabric-conditioner composition.
Claim 10
Dependent Claim
35 words
The article of claim 4, in which the fabric-conditioner composition comprises: about 75.0% by weight dimethyl di(hydrogenated tallow) ammonium methyl sulfate, and at least about 9.0% by weight of nonionic substances including tallow glyceride ethoxylates.
