Abstract: High yields of 2,2'-oxodisuccinate are secured by reacting maleate and malate in aqueous alkaline media containing mixtures of particular divalent (e.g., Ca.sup.2+) and solubilizing monovalent (e.g., Na.sup.+) cations. In a preferred embodiment, the process has both an elevated temperature primary reaction step and one or more low temperature maturation steps. Yields of 2,2'-oxodisuccinate are increased and formation of fumarate byproduct is minimized.

Abstract: Stable isotropic liquid detergent compositions containing a particular silicone suds controlling agent, a sudsing detergent surfactant and water. Such compositions can be prepared if a suitable dispersing agent is premixed with the suds controlling agent prior to incorporation in the liquid detergent composition.
Abstract: Detergent compositions capable of providing through-the-wash softness and other fabric-care benefits are disclosed, which contain a specific amide softening agent.

Abstract: This invention relates to homogeneous liquid laundry detergent compositions containing a mixture of anionic and nonionic synthetic detergents, fatty acid soap, polycarboxylate builder, solvent, and water. Improved odor and safety are obtained by omitting C.sub.1 -C.sub.6 monohydric alcohols which have been used in prior art compositions of this type, and using polyols exclusively for the solvent.
Abstract: Amines and phosphates esters and amine oxides are combined to provide water-insoluble, water-dispersible fabric softeners. The softeners are formulated in a variety of laundry compositions.
Abstract: Spray dried detergent granules containing high levels of certain surfactants are compacted under certain conditions and admixed with other ingredients to form dense, rapidly dissolving detergent compositions.

Abstract: Personal cleansing compositions comprising alkali metal soap and guar gum-coconut fatty acid-sodium hydroxide complex and exhibiting improved physical properties, lather properties, and mildness. The toilet bars comprise alkali metal soap and from about 0.5 to about 8% by weight guar gum, which guar gum is provided as a pre-reacted complex prepared by suspending one part by weight guar gum in from about 1 to about 12 parts by weight molten coconut fatty acid and reacting with the suspension from about 0.03 to about 0.2 part by weight sodium hydroxide per each part by weight coconut fatty acid.
Abstract: Detergent granules containing more than about 18% of anionic surfactant that forms a sticky middle phase are surface treated with a small amount of a water soluble quaternary ammonium salt in an aqueous solution to improve the dissolving characteristics of the composition.
Abstract: A granular detergent having a phosphorus content of less than 5% comprising:(a) about 5% to about 50% by weight of a water-insoluble aluminosilicate ion-exchange material and(b) about 0.1% to about 20% of a polycarboxylate polymer comprising:(i) about 5% to 70% of a C.sub.3 -C.sub.10 monoolefinic monocarboxylic acid,(ii) about 5% to 70% of a C.sub.4 -C.sub.6 monoolefinic dicarboxylic acid, and(iii) about 1% to 80% of a nonionic spacer selected from esters of (i) and (ii), C.sub.2-6 monoolefinic alcohols, and esters of C.sub.2-6 monoolefinic alcohols.The compositions display excellent bleach stability, fabric care and detergency performance at low or zero phosphate levels.
Abstract: Detergent compositions comprising surfactant, at least one detergency builder, and a plurality of rinse cycle suds control prills comprising fatty acid soap, quaternary ammonium salt, and silicone fluid suds suppressor. The granular detergent compositions of this invention provide control of the level of suds on the surface of the water during the rinse cycle without interfering with the level of suds on the surface of the water during the wash cycle of laundering operations.
Abstract: Per-acids and per-acid precursor compounds of the general type RXAOOH and RXAL, wherein R is a hydrocarbyl group, X is a hetero-atom. A is a carbonyl bridging group and L is a leaving group, especially oxybenzenesulfonate, are useful bleaching compounds for fabrics. Laundry products containing same are disclosed.
Abstract: A bleach activator composition in the form of spray-dried granules having an inner core comprising water-soluble organic peroxyacid bleach precursor and a surface coating comprising a water-soluble or water-dispersible, inorganic hydratable material, and wherein the composition has a pH (1% aqueous solution) in the range from about 3 to about 8.The compositions have excellent storage stability and water dispersibility together with simplified processing. Bleach and laundry compositions containing the bleach activator are also disclosed.
Abstract: A detergent composition containing a semi-polar nonionic detergent, an alkaline earth metal salt of an anionic detergent, and an amidoalkylbetaine. The composition is especially useful for the removal of greasy soils and has good suds mileage.

Abstract: This invention relates to bleaching compositions. More particularly, this invention relates to bleaching compositions that provide effective and efficient bleaching performance on textiles. Such bleaching performance is obtained over an extremely wide class of stains and wide range of temperatures of the bleaching solution of pH. The bleaching compositions within the invention contain a halogenated peroxybenzoic acid and a bleach activator that contains a carbonyl carbon atom that can potentially react with such peroxybenzoic acid to form a diacyl peroxide compound or essentially any peroxycarboxylic acid and a bleach activator that contains a carbonyl carbon atom that has an alkyl group containing from about 5 to about 17 carbon atoms and can potentially react with a peroxycarboxylic acid to form a diacyl peroxide compound. In a highly preferred embodiment the bleaching compositions within the invention are detergent compositions.
Abstract: Stable liquid dishwashing detergent compositions are provided incorporating an alkyl benzene sulfonate and/or alkyl sulfate, an alkyl ethoxy sulfate, an ethoxylated C.sub.6 -C.sub.13 alcohol containing an average of from 3 to 12 moles of ethylene oxide and wherein the ethoxylated alcohol contains no more than 1% by weight of unethoxylated alcohol and a zwitterionic surfactant containing a C.sub.10 -C.sub.16 alkyl group.
