  • Patent number: 4252656
    Abstract: A composition for conditioning fabrics in a laundry drier is contained in a pressurized dispensing container and is dispensed as a stable foam. The composition comprises, by weight, 0.2 to 10% of one or more of a group of polymeric conditioning agents, such as polyvinyl pyrrolidone; 1 to 25% of a softening agent, such as a betaine; 0.5 to 10% of foaming agent; 0.2 to 3% of foam stabilizer; 0.5 to 10% of humectant; 10 to 60% of water; and 10 to 80% of liquified gas propellant.
    Type: Grant

  • Patent number: 4242377
    Abstract: Fabrics, such as those in laundry items, are softened and their tendency to accumulate static charges is lessened by application to them of a foam which includes a foaming agent, a fabric conditioner, to improve fabric softness and/or to diminish static, a normally gaseous propellant and water, after which application the laundry is tumbled, preferably in a dryer. The foam thereby becomes spread over the fabric surfaces, conditioning the laundry during a drying operation. In some products a single material may be both foaming agent and conditioner. In other formulations a foam stabilizer will be incorporated to aid the foaming agent in making a more useful foam.In preferred embodiments of the invention, the conditioning composition is a liquid held under its own pressure in a dispensing container and is discharged from it as a stable foam onto the material to be conditioned, which is in a laundry dryer.

  • Patent number: 4041205
    Abstract: An improved article for conditioning fabrics includes at least one fabric conditioning compound, such as a softening agent, and a reinforcing, strengthening or extending material. The fabric conditioning compound and the article comprising it are usually of a waxy nature and are abradable or otherwise transferable to damp, warm fabrics by repeated contacts therewith experienced during tumbling effected in a drying zone, as of an automatic laundry dryer, through which hot drying air normally circulates. When such a softening article is rubbed against fabrics with which it comes in contact in the heat of the drying zone, softener is rubbed off onto the fabrics to be conditioned, after which the fabrics and laundry containing them are dried. The reinforcing or strengthening material is also dried at that time and is either removed from the fabrics by exiting drying air or is desirably held onto the fabrics that were treated, in conjunction with the softening agent.

  • Patent number: 4013475
    Abstract: Wax polishing compositions in the form of a double emulsion wherein the continuous phase comprises organic solvent, organopolysiloxane and water-in-oil emulsifier and the discontinuous phase comprises aqueous particles having dispersed particles of wax therein. Compositions are prepared by adding at room temperature an aqueous media containing emulsified wax to a solvent solution containing organopolysiloxane and water-in-oil emulsifier, also at room temperature.
