  • Patent number: 6894018
    Abstract: A process for the production of granular detergent compositions is provided wherein fluid bed granulation is employed in conjunction with selected recycle of oversized particles to control the uniformity of the resulting detergent composition. The process comprises feeding starting ingredients into a fluid bed granulator to at least partially granulate the feed material while employing the fluid bed to control undersized particle generation and sizing in conjunction with recycle to control oversized particles.

  • Patent number: 6767882
    Abstract: A process for preparing detergent particles having a coating layer of water-soluble inorganic material is provided. The detergent particle comprises a particle core of a detergent active material. This particle core is then at least partially covered by a particle coating layer of a water soluble inorganic material. Particularly preferred are non-hydrate inorganic coating materials including double salt combinations of alkali metal carbonates, and sulfates. The particle coating layer may also include detergent adjunct ingredients such as brighteners, chelants, nonionic surfactants, co-builders, etc. The process includes the steps of passing the particle core through a coating mixer such as a low speed mixer of fluid bed mixer and coating the particle core with a coating solution or slurry of the water soluble inorganic material.

  • Patent number: 6696395
    Abstract: Bottle aqueous household cleaning, fabric treatment and deodorizing compositions comprising surfactant, and a perfume which contains a substantial proportion of hydrophobic perfume ingredients having a ClogP of greater than 3. The bottles are made of high density polyethylene wherein the bottles have a continuous inner surface layer of nylon, polyetheneterephthalate or fluorinated polyethylene in order to prevent migration into and/or transmission through the high density polyethylene of the hydrophobic perfume ingredients.

  • Patent number: 6689739
    Abstract: The present invention relates to detergent compositions which comprise low levels of inorganic sulphate filler salts, but instead high levels of carbonate salts and a system to counter balance the carbonate. This system comprises a floculating agent and a clay. Preferably only very low levels of an inorganic sulphate salt are present. Preferably, also other salts or silicates are present, including phosphates and/or zeolites.
