Abstract: Aqueous compositions comprising water having dispersed therein (A) a cationic compound which is substantive to water rinse on textile fabrics and (B) a mixture of (i) a siloxane composed of at least 90% of RSiQ.sub.3/2 units, in which R is alkyl having from 1 to 8 carbon atoms, and optionally units selected from ##EQU1## units, in which R' is phenyl or a 1 to 4 carbon alkyl group, and C.sub.6 H.sub.5 SiO.sub.3/2 units and (ii) a polydiorganosiloxane.The compositions are useful as fabric conditioners in domestic and commercial laundry operations.
Abstract: Aqueous liquid fabric softening compositions that have been exposed to low temperatures and "gelled", can be recovered and the original dispersion reformed by heating the compositions to above the Krafft temperature of the composition and then applying shear. Only very light shearing action is required to make the compositions free-flowing again. Electrolyte can be added to aid in recovery. The process can use many different kinds of heating and the process can be applied to both packaged and bulk products.
Abstract: Stripper compositions for coatings comprise trioxane. An aromatic hydrocarbon and aliphatic alcohol can be added to improve solubility parameters. Xylene and methanol are the preferred co-solvents.
Abstract: Powdered, abrasive, hard surface cleansers containing micro-encapsulated perfume wherein the capsules are essentially water-insoluble, but can become perfume permeable during use by the combined action of water and abrasive. The preferred capsules are formed from gelatin and a polyanionic material by coacervation techniques and then are cross-linked to provide controlled water insolubility.
Abstract: Hydrophobic textile materials can be dyed or printed with one or more monoazo dyes of the formula ##STR1## in which R.sup.1 is fluoro, chloro or bromo;R.sup.2 is hydrogen or chloro; andR.sup.3 is allyl, alkyl having 1 to 4 carbon atoms, alkoxyalkyl having 2 to 4 carbon atoms in the alkyl portion and 1 to 4 carbon atoms in the alkoxy portion or cyanoalkyl having 2 to 4 carbon atoms.
Abstract: A process for producing 2,5-diamino-6-nitropyridine derivatives having the general formula (I) ##STR1## wherein R.sup.1 to R.sup.4 represent hydrogen or the radicals alkyl, hydroxy alkyl, dihydroxy alkyl, alkoxy alkyl, alkoxy carbonyl, hydroxy- or chlorine-substituted alkoxy carbonyl, aminoalkyl and aminoalkyl substituted by alkyl or hydroxy alkyl groups, the alkyl groups in each case containing 1 to 4 carbon atoms or an oxazolidinone ring being formed by R.sup.1 and R.sup.2 and/or R.sup.3 and R.sup.4. The present invention also relates to novel 2,5-diamino-6-nitropyridine derivatives and to a hair dyeing agent containing 2,5-diamino-6-nitropyridine derivatives, which are direct nitro dyes coloring the hair yellow orange to blue violet and are physiologically harmless.
Abstract: Microcapsules which are prepared using coacervation processes and/or which have a complex structure in which there is a large central core of encapsulated material, preferably perfume, and the walls contain small wall inclusion particles of either the core material or some other material that can be activated to disrupt the wall are disclosed. The microcapsules that are prepared by coacervation and contain perfume are especially desirable for inclusion in fabric softener compositions that have a pH of about 7 or less and which contain cationic fabric softener. The encapsulated perfume preferably does not contain large amounts of relatively water-soluble ingredients. Such ingredients are added separately to the fabric softener compositions. Ingredients that have high and low volatilities as compared to, e.g., the desired perfume, can either be added to, or removed from, the perfume to achieve the desired volatility.
Abstract: A fabric softener sheet for in-dryer use is provided which comprises water, an organic solvent, and an amount of an alkali metal stearate effective to dimensionally-stabilize the sheet, having uniformly distributed in said sheet an effective amount of a quaternary amine fabric softening agent.
Abstract: This invention pertains to the use of chlorofluoropolyethers, such as perfluoropolyepichlorohydrin as lubricants for cooling systems which employ hydrofluorocarbon refrigerants, such as 1,1,1,2-tetrafluoroethane.

Abstract: Substituted 3-aryl amino-indoline-2-ones, produced by the reaction of certain isatins and amines are among a group of compounds useful as hair colorants. The hair itself appears to function as a dye-formation promoter, so that no oxidative reagents are needed.
Abstract: A light duty microemulsion liquid detergent composition, useful for removing greasy soils from surfaces with both neat and dilute forms of the detergent composition, includes a moderately water soluble complex of anionic and cationic surfactants, in which complex the anionic and cationic moieties are in essentially equivalent or equimolar proportions, an anionic detergent, a co-surfactant, an organic solvent and water.
