Abstract

Washing products comprising a dye transfer inhibitor selected from triazine derivatives of the general formulae T(NH—Ar(SO3Na)a)bHalc (I), X(NH-T(NH—Ar(SO3Na)a)eHalf)2 (II), X(NH-T(NH—Ar(SO3Na)d—NH-T(NH—Ar(SO3Na)a)Hal)Hal)7 (III) and combinations thereof, wherein T represents a 1,3,5-triazinyl; each Ar independently represents a naphthalene or benzene; X represents a divalent hydrocarbyl selected from linear or branched C1-20 hydrocarbon groups optionally including one or more —N(H)— carbon chain interruptions, stilbene and biphenyl groups which may optionally be mono- or poly-SO3Na-substituted; each Hal independently represents a halogen selected chlorine, bromine, and iodine; each of a and d independently represents 1, 2 or 3; b and c each represent 1 or 2 such that b+c=3; e represents 1 or 2 and f represents 0 or 1 such that e+f=2; and wherein the triazinyl substituents are located at the 2, 4 and 6 positions of the 1,3,5-triazinyl.
