  • Patent number: 6174851
    Abstract: Storage-stable homogeneous granules with detersive properties, which are obtained by agglomeration of one or more solids with one or more granulation liquids in a free-fall mixer divided into a mixing zone and a post-mixing zone and comprising a knock-down bar fixed to an end plate from which it crosses the entire mixing zone and optionally extends into the post-mixing zone and are optionally aftertreated, may be produced by in situ neutralization of anionic surfactant acids. The products thus produced show distinct performance advantages, the process also having cost-efficient aspects.

  • Patent number: 6172033
    Abstract: A process for conditioning pastes comprising at least 40% by weight of anionic surfactant is provided. The paste is conditioned by mixing alkyl sulphate powder with the surfactant paste in a ratio of at least 1 part powder to 100 parts paste. This conditioning step increases the viscosity of the surfactant paste. The conditioned paste is processed into agglomerates by granulating with builder powders wherein the ratio of high viscosity paste to builder powder is from 9:1 to 1:5. This process enables detergent agglomerates with high surfactant activity to be formed.

  • Patent number: 6156715
    Abstract: The dimensionally stable alkaline solid block warewashing detergent uses an E-form binder forming a solid comprising a sodium carbonate source of alkalinity, a metal corrosion protecting alkali metal silicate composition, a sequestrant, a surfactant package and other optional material. The solid block is dimensionally stable and highly effective in removing soil from the surfaces of dishware in the institutional and industrial environment. The E-form hydrate comprises an organic phosphonate and a hydrated carbonate.

  • Patent number: 6060444
    Abstract: A process for preparing a homogeneous, solid cleaning composition that comprises a cleaning agent, and optionally an additive agent and a hardening agent. The compositions are processed in a continuous mixing system at high shear, at or below the melting temperature of the ingredients. Preferably, the ingredients are processed in an extruder, and the mixture is extruded directly into a mold or other packaging system for dispensing the cleaning composition. The consistency of the composition ranges from that of a fused block solid to a malleable article. The cleaning compositions are useful for warewashing and cleaning hard surfaces, rinsing, sanitizing, deodorizing, laundry detergents, conveyor lubricants, and the like.

  • Patent number: 6034050
    Abstract: A process for producing an anionic surfactant-containing alkali metal silicate-alkali metal carbonate compound providing multiple wash cycle performance, wherein the compound contains 15% to 50% by weight of alkali metal silicate which is x-ray amorphous and has a molar M.sub.2 O to SiO.sub.2 ratio of 1:1.5 to 1:3.3 and M represents an alkali metal, 30% to 70% by weight of alkali metal carbonate, 1.5% to 15% by weight of anionic surfactant and 12% to 19% by weight of water, by providing a powder component selected from alkali metal carbonate, alkali metal silicate, or a mixture of alkali metal carbonate and alkali metal silicate, and agglomerating the powder component with an aqueous composition containing one or more anionic surfactants.

  • Patent number: 5994281
    Abstract: The present invention relates to personal wash bar compositions, particuly compositions comprising (1) lathering anionic surfactants (e.g., sodium acyl isethionate or fatty acid soap); (2) specific solid, less hygroscopic amphoteric surfactants (e.g., disodium N-lauryl iminodipropionate). The invention relates to the incorporation of significant levels of said solid amphoteric surfactant into the specific bar compositions to achieve superior skin mildness and bar user properties. The invention especially addresses the advantages of using solid, less hygroscopic amphoteric surfactants to reduce the processing difficulties in extrusion and modified extrusion processes.
