Fig. 15.9. a Calibration curve for tracking the composition of mixtures of vitamin E
(α-TH) and vitamin E acetate (α-TAc). The origin of the ordinate scale is discussed
in the text. b A Raman image of the spatial distribution of the ordinate scale
parameter in Fig. 15.9a measured in a skin sample to which α-TAc has been added.
The image tracks the spatial distribution and extent of hydrolysis of α-TAc
