Abstract
The changing palette of precursor used in commercial oxidation hair dyes ov er the period 1900 to 1997 is reviewed. Reasons for changes in the palette are discussed in the light of regulatory and patent activity together with comment on the changes in the paradigm for patentability of combinations of known ingredients in known generic combination.
