The interaction of the acid dye Biebrich Scarlet (C.I. Acid Red 66) with α‐, β‐, and γ‐keratoses obtained from wool fiber by performic acid oxidation was studied. The extrapolated saturation values of dye bound to protein and the association constants for the interactions were obtained. Maximum dye uptake was found for α‐keratose, followed by γ‐ and β‐keratoses, in that order. Incorporation of varying amounts of m ‐cresol in the dye solutions showed no significant effect. There was no indication of an interaction between m ‐cresol and the keratoses from direct studies.
