BENZENE DERIVATIVES IN OXIDATIVE HAIR DYEING 211 These results show that the inclusion ofp-aminophenols in oxidation dye formulations contributes significantly to the color produced on hair and the resultant dyes have comparable stability to those formed from p-phenylenediamine.

Chem., 30, 213-239 (July/August 1979) Topologie der Hautoberflache UDO HOPPE' Synopsis • A mathematical and statistical description of the relief structure of b. pman stratum comeum requires a large number of measurements. In order to generate such•,O,ata and on the basis of previously describedprocedures, a semi-automatic apparatus was developed which permitted quantitative estimation of changes in the structure of stratum comeurn. The following parameters were derived: 1. signal inversion and analog/,&'gital conversion for roughness measurements 2. radial measurements { 12 at 3,0•i•mtervals} an a circular skm surface replica of silicone rubber 3. transformation of all machine generated data points, storage, and sorting of data 4. analysis of the frequency distribution of the data and occasional graphical representation 5. determination of significance of the available distribution functions and analysis of variance 6. superposition of "not-significantly different" frequency distributions as well as mathe- matical/statistical evaluation and descnption of sigrd[icantly different data. Data on swelling by externally applied agents and a correlation with effects due to age are also presented.
