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.
