Triazine derivative dye transfer inhibitors, washing products containing the same and uses therefor

A washing product comprising a surfactant and a dye transfer inhibitor selected from the group consisting of triazine derivatives of the general formulae I, III and combinations of formula I, II or III thereof:

• 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)2 (III)
• wherein the product comprises at least one triazine derivative of the general formula III, wherein T represents a 1,3,5-triazinyl residue;
• each Ar independently represents a naphthalene or benzene moiety;
• X represents a divalent hydrocarbyl moiety selected from the group consisting of linear or branched C1-20 hydrocarbon groups which may optionally include one or more —N(H)— carbon chain interruptions, stilbene groups and biphenyl groups which may optionally be mono- or poly-SO3Na-substituted;
• each Hal independently represents a halogen selected from the group consisting of 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 residue substituents are located at the 2, 4 and 6 positions of the 1,3,5-triazinyl residue.
