  • Patent number: 5883065
    Abstract: An emulsified detergent composition is provided. The detergent composition comprises from about 0.1% to about 70%, by weight of the detergent composition, of a detersive surfactant wherein at least from about 70% to about 90%, by weight of the detersive surfactant, is a nonionic surfactant. The detergent composition also includes an electrolyte, in an amount sufficient to render the cloud point of the detergent composition to be less than about 20.degree. C., and water. The detersive surfactant and the water are in two phases in a weight ratio of about 1:10 to about 10:1 in the detergent composition. Superior cleaning and stain removal results because the emulsified detergent composition provides separation of the water and surfactant phases in a low water wash system over a broad temperature range and allows for cleaning below the cloud point of the surfactant system.

  • Patent number: 5565137
    Abstract: A process for preparing high density detergent agglomerates having a density of at least 650 g/l is provided. The process comprises the steps of: (a) continuously mixing a detergent surfactant paste and dry starting detergent material into a high speed mixer/densifier to obtain detergent agglomerates, wherein the ratio of the surfactant paste to the dry detergent material is from about 1:10 to about 10:1; (b) mixing the detergent agglomerates in a moderate speed mixer/densifier to further densify and agglomerate the detergent agglomerates; and (c) drying said detergent agglomerates so as to form the high density detergent composition. The process may include one or more additional processing steps such as adding a coating agent after the moderate speed mixer/densifier to facilitate and control agglomeration.
