Definitions

  • the present invention relates to fabric care and laundry detergent compositions which comprise a fabric enhancement system in combination with a transition metal-compnsmg dye protection system, which acts to mitigate the loss of fabric color, providing a laundry composition which provides enhanced fabric appearance benefits.
  • Formulators of fabric care and laundry detergent compositions include va ⁇ ous ingredients, inter aha surfactants, cationic softening actives, anti-static agents, dye transfer inhibitors, and bleach-damage mitigating agents, for the purpose of improving cleaning, fabric appearance, fabric feel, fabric color and to extend the duration of fabric life. Ingredients which are added to these compositions must not only provide a benefit, but must be compatible with a variety of product forms, i.e.
  • high density granules, liquid dispersions, isotropic liquids includmg clear, colorless/translucent liquids which may include principal solvents inter aha 1 ,2- hexanediol, 2,2,4-t ⁇ methyl-l,3-pentaned ⁇ ol (TMPD).
  • TMPD 2,2,4-t ⁇ methyl-l,3-pentaned ⁇ ol
  • adjunct ingredients which provide fabric enhancement benefits are highly fab ⁇ c substantive and, therefore, once deposited on the fabric surface remain with the fabric thereby providing the intended benefit until chemically altered or until displaced by a more fab ⁇ c substantive mate ⁇ al.
