To the Editor:—
I am sure, by this time, that you have been inundated with information concerning "Man Tan." However, there have been so many inquiries concerning this product, both by physicians and the lay public, that some information should be given them.Most dermatologists have taken the stand that since we do not know about "Man Tan," the patients are advised not to use it. Just in case that this material has not been expounded upon so far in the Archives, let me do so.According to a story in Chemical Week, and in Drugs and Cosmetics (December) 1959, "Man Tan" is supposed to contain dihydroxyacetone, alcohol, water, and vitamin D. "Dihydroxyacetone, OHCH2COCH2OH is a compound that readily forms an equilibrium mixture with glyceraldehyde, CH2OHCH2OHCHO, and is probably oxidized by air to caramel-related polymer with a yellow-brown color."Further reference on
