  • Patent number: 5977055
    Abstract: Softener actives provide color maintenance benefits for fabrics. In order to inform the consumer, the compositions containing fabric softener actives are placed in packages in association with information that advises the consumer of the benefit. Highly unsaturated fabric softener active compounds, preferably containing ester linkages, are used at levels of at least about 3 grams of fabric softener active per kilogram of fabric deposited on said fabric to provide improved softening, anti-static benefits, wear benefits, color maintenance, etc., without unacceptable oily/greasy feel and/or unacceptable rewettability.

  • Patent number: 5707959
    Abstract: A process for preparing high density detergent compositions 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 dry detergent material may contain a builder material including a crystalline microstructure in which a carbonate anion, a calcium cation and at least one water-soluble cation are contained. The process may include one or more additional processing steps such as adding a coating agent such as the builder material described herein after the moderate speed mixer/densifier to facilitate and control agglomeration.
