Abstract: This invention provides a powder carbonate-based laundry detergent which can be utilized in cold water fabric laundering with a minimized remainder of undissolved detergent residue in the wash water. An essential aspect of the laundry detergent formulation is a content of a partially sulfated and neutralized blend of ethoxylated alcohol surfactant constituents. A preferred type of surfactant ingredient is a Neodol 23-3 derived type of blend which is 60-65 percent sulfated and neutralized.

Abstract: This invention provides a high carbonate-low phosphate powder laundry detergent formulation which can be utilized in cold water fabric laundering with a minimized remainder of undissolved detergent residue in the wash water. An essential aspect of the laundry detergent formulation is a content of a partially sulfated and neutralized blend of ethoxylated alcohol surfactant constituents. A preferred type of surfactant ingredient is a Neodol 23-3 derived type of blend which is 50-65 percent sulfated and neutralized. Another essential aspect is a content of polyethylene glycol ingredient which increases the solubility of the laundry detergent solids in the wash water.

Abstract: A process for preparing a free-flowing high bulk density granular laundry detergent product comprises pre-blending a powder admixture comprising (1) between about 40-90 weight percent of a water soluble detergent builder wherein at least 70 weight percent of the detergent builder is sodium carbonate, and (b) between about 0.5-10 weight percent of alkali metal chloride salt, (2) forming a builder-surfactant powder by blending the step (1) admixture with between about 5-40 weight percent of a detergent active ingredient which is a blend of sulfated ethoxylated alcohols and nonionic ethoxylated alcohols, (3) subjecting the builder-surfactant powder to treatment with water under agglomerating conditions, and (4) drying the detergent composition to provide a free-flowing granular laundry detergent product having a bulk density of at least 650 grams per liter, and in which the detergent granule surfaces are coated with a glossy shell of alkali metal salt crystallites.

Abstract: This invention provides a free-flowing high bulk density granular detergent product for heavy duty textile laundering utility. One essential aspect of an invention detergent product is a content of a partially sulfated and neutralized blend of ethoxylated alcohol surfactant constituents. Another essential aspect is a unique granule structure in which the surfaces are coated with a non-tacky glossy shell of alkali metal chloride salt crystallites. The said glossy coating facilitates free-flowing and tight-packing of the granules into a high bulk density compact mass.

Abstract: A laundry detergent composition, wherein the solids content comprises an active surfactant, at least about 70 wt. % of a water soluble alkaline carbonate, e.g., sodium carbonate, and, a minor amount, for example, about 0.05 to 5 wt. % of a polymeric polycarboxylate, e.g., an acrylic acid polymer, based on the total weight of solids in the composition, the polymeric polycarboxylate being in a form such that its complete release into wash water is delayed to at least about 60 seconds after the complete dissolution of the alkaline carbonate. For example, the polymeric polycarboxylate may be present in slow dissolving granules which also contain a diluent salt such as sodium carbonate and a binder such as a low molecular weight polyethylene glycol. The delayed release of the polymeric polycarboxylate reduces fabric encrustation during washing, i.e., the precipitation of CaCO.sub.3 onto fabric surfaces due to the presence of soluble alkaline carbonate.

Abstract: This invention provides a powder carbonate-based laundry detergent which can be utilized in cold water fabric laundering with a minimized remainder of undissolved detergent residue in the wash water.A particulate anionic surfactant ingredient such as sodium lauryl sulfate is incorporated by dry blending with detergent granules to form an adherent coating of fine particles of anionic surfactant on the detergent granules, in a quantity which is effective for reducing the residue of undissolved detergent under cold water laundering conditions.

Abstract: This invention provides a sodium carbonate-based laundry detergent powder which can be utilized in cold water fabric laundering with a minimized remainder of undissolved detergent residue in the wash water. A water-soluble fatty acid salt such as sodium stearate is incorporated as an adherent coating on the detergent granules, in a quantity which is effective for reducing the residue of undissolved sodium carbonate under cold water laundering conditions.

Abstract: A heavy duty detergent composition of a solvent, an anionic detergent component in acid form, a fatty acid, an alkali metal hydroxide, a nonionic detergent, a hydrotrope, a buffering agent, a dye and a builder mixed by adding substantially all of the solvent to the vessel, and adding the remaining components in any order so long as the builder is added to the vessel prior to neutralization of the anionic detergent from acid to salt form by the alkali metal hydroxide. The builder alone prevents degradation of the dye color or a chelating agent and the builder may be employed to prevent color degradation. When added in solution, the chelating agent or the builder increases the volume of the vessel mixture. Heat released in neutralization is absorbed by a larger volume of liquid. Neutralization thus does not raise the temperature of the components in the vessel as high as if chelator or builder solution were added later. Neutralization may be performed more quickly and batch processing times may be reduced.

Abstract: Bleaching compositions containing coated or encapsulated bleaching agents, methods for employing these coated agents, as well as methods for preparing these encapsulates are disclosed. These compositions and methods are utilized to effectively bleach colored fabrics and textiles in both hot and cold water with minimal pinpoint damage to the fabric colors. The encapsulates have excellent storage properties and release of the active component at both hot and cold temperatures.
