Abstract

A novel and highly sensitive method for the determination of some heavy metals in skin whitening cosmetics creams using multiwalled carbon nanotubes MWCNTs as solid phase extraction sorbent for the preconcentration of these heavy metals prior to their determination by inductively coupled plasma atomic emission spectrometry is described. Different practical parameters have been thoroughly investigated and the optimum experimental conditions were employed. The developed method was then applied for the determination of arsenic, bismuth, cadmium, mercury, lead and titanium in samples of skin whitening cosmetics. The detection limits under these conditions for As, Bi, Cd, Pb, Hg and Ti were 2.4, 4.08, 0.3, 2.1, 1.8, and 1.8 ng·mL−1, respectively. The relative standard deviations (RSDs) were found to be less than 2.0%. For validation, a certified reference material of NIST SRM 1570a spinach leaves was analyzed and the determined values were in good agreement with the certified values. The recoveries for spiked samples were found to be in the range of 89.6–104.4%.

  • Alquadami et al. in 2013 found arsenic levels in 34 skin whitening creams ranging from 0.34 to 14.76 μg/g.

    “Alquadami et al. in 2013,34 who found Arsenic levels in thirty-four (34) skin whitening creams ranging from a low of 0.34 μg/g to a high of 14.76 μg/g.”

    From The Evaluation of Total Mercury and Arsenic in Skin Bleaching Creams Commonly used in Trinidad and Tobago and their Potential Risk to the People of the Caribbean (2017) · cites this paper as [34]

    Methods §2.3 reports 34 skin-whitening cosmetics, and Results §3.8 reports a minimum arsenic concentration of 0.34 µg/g. But §3.8 and Table 8 give the maximum as 15.36 µg/g (sample 19); the cited 14.76 µg/g is the concentration in sample 25, not the maximum. Page numbers are unavailable in our copy. (LLM, conf=0.93)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
