  • Patent number: 6093387
    Abstract: The present invention provides water-soluble, extended-release chemical formulations, in tablet form, for urine pretreatment, that require minimal, if any, use of a binder component, yet are non-dusting, pliable, structurally strong, and not weakened by exposure to aqueous streams. The present invention also provides a simple and reliable method for controlled dispensing of such tableted formulations into a liquid stream that is particularly advantageous for use in micro-gravity environments, such as spacecraft urinal systems.

  • Patent number: 6093688
    Abstract: The speed of disintegration of tablets containing a water-softening agent, especially water-insoluble, water-softening agent intended as detergency builder for fabric washing is enhanced by incorporating sodium acetate trihydrate, potassium acetate or a mixture thereof. To inhibit caking and facilitate handling during manufacture, smaller particles of another substance are preferably provided at the surface of the crystals of the acetate or citrate.

  • Patent number: 6083893
    Abstract: The present invention provides a firm, mild, good performing, low-smear semi-solid or solid dishwashing product. The rheology of the dishwashing product is such that structural elements have been separated from functional elements to obtain best structure properties and in-use properties. By using an interlocking mesh of carboxylic acid and/or neutralized carboxylic acid fibers and/or platelets to provide a support structure, the semi-solid or solid dishwashing product can be loaded with superior performing dishcare materials (e.g., mild surfactants) and appearance enhancers without dependence on surfactant-water phase behavior to provide the support structure. As a result, the present dishwashing product is milder than semi-solid dishwashing products currently on the market. The support structure of the present product, and preferably the use of hygroscopic surfactants, provide a product with lower smear than current gel dishwashing products.

  • Patent number: 6080711
    Abstract: A powdered laundry detergent is provided with (a) a powder laundry detergent base that includes an inorganic carrier and a surfactant and (b) post-added acidulant and discrete whitening agent particles to provide a detergent having improved cool water solubility with bulk color deterioration caused by whitening agents being minimized. The detergent includes from about 5% to about 80% of an inorganic carrier, from about 1% to about 90% of a detergent surfactant, from about 0.1% up to about 15% of an acidulant and from about 0.1% up to about 30% of the discrete whitening agent particles. The acidulant is selected from the group of acids that in an acid form are soluble in water in an amount not greater than about 8%, preferably not greater than about 0.7% by weight at 25.degree. C. and in a salt form are soluble in water at least in an amount of about 15% by weight at 25.degree. C. The whitening agent particles include a whitening agent and a surfactant.
