“…Literature survey reveals some analytical methods are developed for the determination of PPD by HPLC [10][11][12], GC/MS [13,14], voltametric method [15], emission spectroscopy [16] and some spectrophotometric method are reported. The spectrophotometric methods have their relative merits but the methods are carried out with time consuming in diazotization followed by coupling with N-(1-naphthyl) ethylenediamine [17], involves oxidation of the compound converted in to salt measured colorimetrically [18], coupling of triclosan with reagent 2-aminonaphthalene-4,8disulfonic acid with low level detection [19]. The another method was based on the reaction of sodium nitrite with p-sulfanilic acid in an acidic medium to form diazonium ion, with which triclosan further formed an azo compound in an alkaline medium [20].…”

This study aims to determine the para-phenylenediamine (PPD) in hair dyes by High-Performance Liquid Chromatography (HPLC). In the presented study, ten hair dye samples were collected from local markets in El-Bieda - Libya. A rapid, simple and reliable method is developed and validated for the determination of PPD in hair dyes samples using 50% methanol solution as solvent. The method was validated over a wide linear range of 5 – 25 µg/mL with correlation coefficients being consistently greater than 0.997. The LOD and LOQ were 1.21 µg/ ml and 3.67 µg/ ml, respectively. Relative standard deviation (% R.S.D.) ranged between 0.07 and 1.15 %. The minimum PPD level was observed in Beauty Touch (Blonde) sample (0.0855 % w/w), while Jourin sense Cosmetics (Black Blue) sample showed the highest PPD content (2.2526 % w/w). The HPLC measurments indicated that the results of PPD concentrations in Black colour samples were in the range of 0.3705 % - 2.2526 % w/w. Whereas its concentrations in anthor colour samples were in the range of 0.0855 % - 0.5936 % w/w. The level of PPD in Black colour samples were higher than other colour samples. The PPD content in all the samples analyzed in this study are well below the allowable limits set by the US Food and Drugs Administration.

Henna is frequently used as body adornment in Libya, the Arabic world, and some African and Asian countries. It is part of the traditions and cultures. The addition of para-phenylenediamine (PPD) to the natural henna increases the risk of allergic contact dermatitis as well as toxic effects, which sometimes lead to severe toxicity and death. Cases have already been reported in Al-Bayda city - Libya. This study aimed to identify the presence and determination of PPD in henna by High-Performance Liquid Chromatography (HPLC). In the current study, eleven henna samples were collected from local markets in Al-Bayda - Libya. A rapid, simple, and reliable method is developed and validated for the determination of PPD in henna samples using 50% methanol solution as solvent. The method is validated over a wide linear range of 5 – 25 µg/ml with correlation coefficients being consistently greater than 0.997. The minimum PPD level was observed in a random sample of mixed henna (paste2) (0.0104 % w/w), while the Royal Black Henna sample showed the highest PPD content (11.9107 % w/w). The HPLC measurements indicated that the results of PPD concentrations in the Royal Red henna sample and Shikha henna (natural henna) were PPD free (ND) (Not Detected). The concentrations in Black henna samples were higher than Red henna samples. The PPD content in red henna samples analyzed in this study is below the allowable limits set by the Scientific Committee on Consumer Products (SCCP) and the US Food and Drugs Administration. While in Black henna samples it was higher than that recommended limit.
