Abstract
Processes and uses related to treating fabrics with an organic acid, such as citric acid with certain treatment liquors or consumer product treatment compositions. A process to determine the presence of a metal-based residue on a fabric. Uses of a treatment composition or a treatment liquor to rejuvenate a non-white color of a fabric. Processes to demonstrate and/or display the color-rejuvenation benefits of a treatment composition.
Claims17
A process to determine the presence of a metal-based residue on a fabric, the process comprising the steps of:
- providing a vessel with a storage portion and an open mouth;
- providing a treatment liquor to the storage portion of the vessel,
- the treatment liquor comprising an organic acid,
- optionally, forming the treatment liquor by combining a treatment composition and water, the treatment composition comprising the organic acid;
- submerging at least a portion of the fabric in the treatment liquor for at least two seconds;
- and
- detecting the presence of released metal-based residue into the treatment liquor, wherein the metal of the metal-based residue is calcium, magnesium, copper, aluminum, or mixtures thereof.
