Abstract: An aqueous concentrated cationic fabric softening composition wherein the cationic softener system comprises a mixture of a mono nitrogen quaternary ammonium salt, a di(2-amidoethyl)methyl quaternary ammonium salt and an imidazolinium salt, the said cationic system having an Iodine Value of at least 4.2.

Abstract: Solid cake compositions comprising three essential components: polyethylene oxide resin, a nonsolvent resin coating liquid, preferably a perfume, and a surfactant. The components are mixed to form an extrudable mass and the mass is extruded into a log. The log is then cut or sliced into individual cakes. The compositions have reduced gelling characteristics, which reduce the tendency of the resin to form a gel when the cake is contacted with water. The cakes are useful in dispensers which are employed in the flush tank of a toilet to automatically dispense chemicals to the flush water. The polyethylene oxide resin dispensed into the wastewater minimizes aerosolization of the wastewater which occurs when the toilet is flushed.

Abstract: A comelted, granular fabric softening composition which is water dispersible in the cold water rinse of a washing machine, comprising about 60% to about 85% of a di-(long chain) quaternary ammonium salt and about 15% to about 40% of a mono- (long chain) quaternary ammonium salt having from 10 to 14 carbon atoms in its single long chain. The fabric softening composition may also contain up to about 25% of optional ingredients. In one embodiment of the invention the fabric softening agent is adapted to be placed within a water-permeable envelope. The envelope can be inserted into a washing machine during a laundering operation to provide fabric softening benefits to the clothes being laundered.

Abstract: Method and composition to inhibit the staining of water-contacting surfaces, such as those in a toilet bowl, which is caused by manganese present in household water in the presence of an oxidizing material. Manganese staining is inhibited by supplying to the water 0.1 to 10 ppm of a substance selected from sodium polyacrylates and ethylenemaleic anhydride copolymers. Compositions are also described in the context of an automatic toilet tank dispenser which provides sufficient quantities of the above materials in solution to inhibit manganese staining of toilet bowl surfaces.

Abstract: A hydrophilic or hydrotropic peroxyacid laundry bleach with surfactant plus an acid additive, contained inside a pouch, bag or substrate, provides an accelerated controlled bleach release laundry product.

Abstract: A liquid skin cleanser composition with improved lathering characteristics, comprising:(A) 5-30 weight percent anionic surfactant selected from the group consisting of fatty alkyl sulfates, fatty alkyl ether sulfates and mixtures thereof;(B) 0.5-12 weight percent of a lather boosting mixture consisting essentially of free fatty acids, fatty alkylol amide having a ratio of 1:3 to 3:1,(C) water;wherein said free fatty acids have a carbon atom chain length of from 8 to 18 and wherein said fatty acids consist of at least 25% of carbon chain lengths of less than 14, and wherein said lather boosting mixture is present in an amount equal to 10% to 40% of the weight to the surfactant, and wherein said composition has a pH of from about 4.0 to about 7.0.

Abstract: An improved method for laundering fabrics to remove oily soil is disclosed, wherein fabrics are contacted with a washing liquor comprising an aqueous solution of a nonionic surfactant system and other ingredients. The washing temperature and ingredients of the washing liquor are selected so that washing occurs at a temperature which is substantially above the cloud point of the washing liquor and below the phase coalescence temperature of the washing liquor. Compositions useful in the practice of this invention are also disclosed, comprising a nonionic surfactant to which is added one or more strong electrolytes. Such compositions may be diluted with water to form a washing liquor which has cloud point and phase coalescence temperatures which are tailored for washing, within the scope of the present method, at a temperature preferred in the art. Conventional sequestering detergency builders and adjuvants may be added to the compositions as desired to optimize the cleaning result.

Abstract: An improved liquid material dispenser of the type which transmits fluid to be diffused from an enclosed reservoir to an exposed evaporative surface by means of a wick. A wick is provided in the form of a sheet which has a very high evaporative area compared to the volume of liquid which is retained outside the confines of the reservoir at a given time. The critical relation of evaporation area to volume of liquid outside the reservoir is such that the exposed liquid material weight per square centimeter of evaporative surface is less than 10 milligrams per square centimeter. The material to be dispensed, preferably a perfume, comprises at least 50% of materials of no more than moderate volatility as defined herein. Materials having low volatility as defined herein are minimized, and the quantity of low volatility ingredients in said liquid materials is related herein to the holding capacity of the evaporative surface of the wick.
