  • this invention relates to unit dose fabric softening compositions which are compacted granular compositions suitable for use in the wash cycle of an automatic washing machine.
  • Detergent compositions manufactured in the form of compacted detergent powder are known in the art.
  • U.S. 5,225,100 for example, describes a tablet of compacted powder comprising an anionic detergent compound which will adequately disperse in the wash water.
  • detergent compositions in the form of compacted granular tablets of various shapes have received much attention in the patent literature, the use of such tablets to provide a unit dose fabric softener which will soften or condition fabrics in the wash cycle without impairing detergency or otherwise compromise the cleaning benefits provided by the detergent composition is not known.
  • a unit dose composition for the rinse cycle must be formulated to readily dispense its contents upon contact with water in a period of time corresponding to the residence time of the unit dose in the dispenser, namely, the period of time during which water enters and flows through the rinse cycle dispenser.
  • Laundry detergent compositions which further include a fabric softener to provide softening or conditioning of fabrics in the wash cycle of the laundering operation are well- known in the art and described in the patent literature. See, for example, U.S. Patent 4,605,506 to Wixon; U.S.
  • U.S. Patent 5,972,870 to Anderson describes a multi-layered laundry tablet for washing which may include a detergent in the outer layer and a fabric softener, or water softener or fragrance in the inner layer.
  • the unit dose fabric softening compositions which are compacted granular compositions, must be able to disperse in the wash liquor in a short period of time to avoid any residue at the end of the wash cycle.
  • the wash cycle time can be as short as 12 minutes and as long as 90 minutes (in typical European washers) depending on the type of washer and the wash conditions. Therefore, to make sure that the compacted unit dose is properly dispersed in the wash liquor before the end of the cycle, disintegrating materials must be added to the granules before compacting.
  • water swelling polymers such as polyvinylpyrrolidone, cellulosic polymers or a blend of citric acid and bicarbonate salt that provide an effervescent matrix.

  • the unit dose fabric softening composition is characterized by being in the form of a tablet and having no discrete outer layer surrounding the fabric softener comprised of an alkaline material such that the pH of the wash water is increased upon dissolution of said outer layer in said wash water.

  • the compacted granular fabric softener composition of the invention is preferably comprised of a fabric softening clay optionally in combination with an organic fatty softening material.
  • Especially preferred fabric softeners comprise a clay mineral softener, such as bentonite, in combination with a pentaerythritol ester compound as further described herein.
  • Useful combinations of such softener may vary from about 80%, to about 90%, by weight, of clay, and from about 10% to about 20%, by weight, of fatty softening material such as a pentaerythritol compound (often abbreviated herein as "PEC").

  • the clays that are useful components of the invented products are those which cooperate with the organic fatty softener materials to provide enhanced softening of laundry.
  • Such clays include the montmorillonite-containing clays which have swelling properties (in water) and which are of smectite structure, so that they deposit on fibrous materials, especially cotton and cotton/synthetic blends, such as cotton/polyester, to give such fibers and fabrics made from them a surface lubricity or softness.
  • the best of the smectite clays for use in the present invention is bentonite and the best of the bentonites are those which have a substantial swelling capability in water, such as the sodium and potassium bentonites.
