Definitions

  • the present invention relates to the selection of certain water soluble dyes to be incorporated into liquid fabric softener compositions to reduce staining of fabrics.
  • Fabric softening compositions have long been known in the art and are widely utilized by consumers during the rinse cycles of automatic laundry operations.
  • fabric softening refers to a process whereby a desirably soft hand and fluffy appearance are imparted to fabrics.
  • Dyes are often used in consumer products to provide pleasing aesthetics.
  • fabric care products one wants to be able to provide the desired color aesthetics with as little dye as possible to minimize chances for staining clothes.
  • WO 94/10285 fabric softening compositions comprising a dye system with water soluble Liquitint R dyes.
  • Liquitint R dyes available from Milliken Chemical Co., also reduce staining as disclosed in said WO 94/10285, however a disadvantage of Liquitint R dyes is its color strength. It appears that the color strength of Liquitint R is very low and thus in order to obtain a satisfactory level of colorant in a finished fabric softener product, one need to add high amounts of said Liquitint R dye.
  • Said water soluble dyes when applied in fabric softening compositions also give less hueing than with conventional dyes.
  • Vitasyn R dyes are known as colorants in food, however nowhere is disclosed that Vitasyn R dyes can be used in liquid fabric softener compositions leading to a reduced staining potential. In addition, it appears that the presence of Vitasyn R dyes in the fabric softener compositions surprisingly also leads to less hueing on fabrics.
  • the present invention relates to fabric softener compositions especially liquid fabric softener compositions, comprising a water soluble dye system.
  • This dye system comprises dyes selected from the group consisting of :
  • compositions Most preferred in a composition are the combinations of Vitasyn R dyes Patent Blue V85 and Ponceau or Patent Blue AE85 and Ponceau.
