  • Method of stain removal from garments worn on the body
    Patent number: 6838423
    Abstract: The present invention relates to a method for fabric treatment. More specifically the invention relates to a convenient to carry fabric treatment applicator comprising a heat activatable compound such as a peroxide bleach, which can be advantageously used on clothes while they are worn. Claimed and described is a method for the application of a fabric treatment composition comprising a heat activatable compound such as a peroxide bleach onto a fabric whereby the temperature of the composition is raised with regard to the storage temperature. Further claimed is a fabric treatment applicator comprising a heat activatable compound and a flow interruption means, preferably a valve, to interrupt or allow the flow of the fabric treatment composition.

  • Stain removal pen with optimal application device
    Patent number: 6644879
    Abstract: An applicator for a fabric treatment to effect mechanical stain removal has a no rinse fabric treatment composition and an application device. The application device induces a certain frictional stress upon the fabric and has a frictional stress value on the fabric optimally chosen to effect fabric treatment and is at the same time kind to the fabric. Advantageously, the application device has a frictional stress value of from 0.05 N mm−2 to 1 N mm−2. The frictional stress should be high enough to ensure good mechanical stain removal, good delivery of the fabric treatment composition into the fabric and allow fabric treatment with fabric friendly chemical compositions at low levels.
