ABSTRACT WILLIAMS, TOVA N. Approaches
ABSTRACT WILLIAMS, TOVA N. Approaches to the Design of Sustainable Permanent Hair Dyes (Under the direction of Harold S. Freeman). Interest in designing sustainable permanent hair dyes derives from the toxicological concerns associated with certain commercial dyes, in particular the moderate to strong/extreme skin sensitization potential of certain precursors used to develop the dyes. While work has been undertaken to help address toxicological concerns of hair dyes, alternatives having commercial success are based on the conventional permanent hair dye coloration process and still may pose health problems. The conventional process involves the oxidation of small and essentially colorless precursors (e.g., p-phenylenediamine and resorcinol) within the hair fiber that couple to build oligomeric indo dyes that are difficult to desorb. The resultant depth of shade achieved is superior that of other hair dyes and provides a high degree of gray coverage. In fact, these dyes dominate the commercial realm and stimulate the multibillion-dollar global hair dye market for the millions of consumers (men and women) who use them. Approaches to the design of sustainable (less toxic) permanent hair dyes lie at the heart of the present study. In Part 1 of this study, two types of keratin films (opaque and translucent) were characterized for their potential as screening tools for predicting the efficacy of potential hair dyes using the hair dye, C.I. Acid Orange 7. Translucent keratin films, which were found to be less porous than opaque films and more like hair in this regard, were deemed better tools for predicting the efficacy of potential hair dyes on hair. -

This is a direct corollary of the fact that the intermediates are the materials out of which dyes are fabricated. Furthermore, the tremen- dous complexity of the dye industry, the interrelationship of one dye to another or of one intermediate to another, as well as the relationship of dyes and intermediates to the whole organic chemical industry, all require that there be available tables showing the commercial dyes derived from each important intermediate. To give this is the prime object of this work. -
