Quantitative determination of BHT in soap products by capillary gas chromatography
Abstract A simple and rapid capillary gas chromatography (GC) method is described for the quantitative determination of 2,6-di-tert-butyl-4-methylphenol (BHT) antioxidant in soap bars, fatty acids, and related intermediates. The procedure involves blending the sample with dimethylformamide in the pr...

| 520 | |a Abstract A simple and rapid capillary gas chromatography (GC) method is described for the quantitative determination of 2,6-di-tert-butyl-4-methylphenol (BHT) antioxidant in soap bars, fatty acids, and related intermediates. The procedure involves blending the sample with dimethylformamide in the presence of 2,4-di-tert-butylphenol (DTBP) internal standard, filtering the mixture, silylating an aliquot with BSTFA (bis-trimethylsilyltrifluoroacetamide) and quantifying by capillary GC using flame ionization detection. The silyl derivatization and nonpolar capillary column (12 m, methyl silicone, fused silica) provided resolution of BHT from certain fragrance component interferences. The method has a detection limit of approximately 10 ppm. Soaps fortified with BHT showed recoveries of 97.1±3.7% at the 200 ppm level and 92.3 ± 2.2% when spiked at the 75 ppm level. The effect of bar soap storage time on BHT content is also demonstrated. | ||

Quantitative determination of BHT in soap products by capillary gas chromatography |
| abstract |
Abstract A simple and rapid capillary gas chromatography (GC) method is described for the quantitative determination of 2,6-di-tert-butyl-4-methylphenol (BHT) antioxidant in soap bars, fatty acids, and related intermediates. The procedure involves blending the sample with dimethylformamide in the presence of 2,4-di-tert-butylphenol (DTBP) internal standard, filtering the mixture, silylating an aliquot with BSTFA (bis-trimethylsilyltrifluoroacetamide) and quantifying by capillary GC using flame ionization detection. The silyl derivatization and nonpolar capillary column (12 m, methyl silicone, fused silica) provided resolution of BHT from certain fragrance component interferences. The method has a detection limit of approximately 10 ppm. Soaps fortified with BHT showed recoveries of 97.1±3.7% at the 200 ppm level and 92.3 ± 2.2% when spiked at the 75 ppm level. The effect of bar soap storage time on BHT content is also demonstrated. © American Oil Chemists' Society 1982 |
