Chlorinated bis-phenols, such as studied in this paper; dichlorophene (G-4), hexachlorophene (G-11) and bithionol are used in many cosmetic products and the determination of them in commercial products has been investigated by some authors but only few of them has employed gas chromatography for this purpose.
In the present paper, the author has described a simple gas chromatographic identification of trimethylsilyl (TMS) derivatives of G-4, G-11 and bithionol. A complete separation of these TMS derivatives was possible by using a column containing 20% Silicone SE-31 on 60/80 Celite 545, and by using squalane as the internal standard material. Fatty acids and higher alcohols that could be contained in usual products did not interfere the determination.
A commercial deodorant soap was analyzed by this method and G-11 in it was easily identified. It was concluded that the gas chromatographic determination of TMS derivatives of G-4, G-11 and bithionol is available for these contents in unknown samples.
