[Determination of acetate ion in cosmetics containing lead diacetate (author's transl)].
A method is described through which acetate ion in cosmetics is determined, in order to establish lead diacetate contents. Lead, from sample aqueous solutions is precipitated by 1 M oxalic acid and the resulting free acetic acid is determined via GLC, using propionic acid as internal standard. The lead neutral acetate contents resulting either from gas-chromatographic or lead titrimetric determinations are in good agreement. A typical gas-chromatogram is also reported.
