Definitions

  • composition which provides care to the treated fabrics, in particular color protection, especially after multiple wash cycles.
  • Short fibers are dislodged from woven and knit fabric/textile structures by the mechanical action of laundering. These dislodged fibers may form lint, fuzz or "pills" which are visible on the surface of fabrics and diminish the appearance of newness of the fabric. Further, repeated laundering of fabrics and textiles, especially with bleach-containing laundry products, can remove dye from fabrics and textiles and impart a faded, worn out appearance as a result of diminished color intensity, and in many cases, as a result of changes in hues or shades of color.
  • WO 98/12295 discloses colour care compositions comprising a dye fixing agent and a specific amino-functional polymer.
  • EP 0 811 680 discloses a liquid fabric softening composition comprising one or more fabric softener materials and a mixture of at least two cationic dye fixing agents.
  • WO 96/27649 discloses laundry compositions comprising detergents, as well as rinse-added fabric softeners, comprising from 0.05 CEVU/gram to 125 CEVU/gram of finished product, of a cellulase enzyme and from 0.01% to 50% wt. of a cationic dye fixing agent.
