Definitions

  • the present invention is concerned with improvements relating to detergent analysis and in particular to improvements relating to the preparation of so-called "swatches" for use in such analysis.
  • a "swatch" is a piece of generally flexible material such as a fabric that has a stain applied thereto.
  • the material can be, for example, a fabrics made of cotton, polyester or various mixtures of natural and synthetic fibres.
  • the swatch can be non-woven (e.g. filter paper or nitrocellulose) or even a piece of a hard material, for example, ceramic.
  • the stain may include blood, milk, ink, grass, tea, wine, spinach, gravy, chocolate, egg, cheese, clay, pigment, oil, or mixtures of these components.
  • Swatches are commonly used in the evaluation of laundry detergent compositions. In the traditional "model wash” analysis, as they are a small part of the wash-load, the bulk of the load being made up of "ballast", which comprises various sheets of cloth. One or more swatches (also known as “monitors”) and a quantity of "ballast”, are washed under known conditions so that the degree of stain removal can be determined.
  • United States Patent 7122334 discloses a more modern technique for analysis of detergent compositions.
  • a "smaller swatch" a piece of the swatch that has been cut or otherwise removed from the swatch of material either before or after fixing the stain to the swatch is placed into the well of a 24, 48 or 96 well micro-titer plate.
  • the "smaller swatch” can also be made by applying a stain to a small piece of material. Typically these "smaller swatches” are around 5mm in diameter.
  • “swatch” includes both larger and smaller swatches.
  • Swatches having stains of known "strength" on various types of material are commercially available (from EMPA, St. Gallen, Switzerland; WFK-Testgewebe GmbH, Krefeld Germany; or Center for Test Materials, Vlaardingen, The Netherlands) and/or can be made by the practitioner (as described for example in Morris and Prato, Textile Research Journal 52(4):280 286 (1982 )).
