A number of cosmetics allegedly contain mercury added with the aim of reducing black stains on the surface of the skin. This study aims to analyze the effect of cosmetic use (whitening cream) on Hg levels in the UMI Nurse Internship profession. Sampling using purposive sampling method, the population in this study were nurses profession internship nurses from the Indonesian Muslim University who used a total of 90 people, researchers determined a total sample of 61 people namely nurses Internship profession Study Program UMI generation V as many as 20 people and VI generation nurses as many as 41 people, data analysis using correlation analysis, Pearson test and T test with α = 0.05. The results showed that the average mercury level using whitening cream was 0.33 ppm and not users cosmetics of whitening cream 0.18 ppm, with mercury levels from the lowest to highest incosmetic wearers whitening for 0.04-2 ppm and non-cosmetic whitening creams amounted to 0.07-0.36 ppm, this indicates that there are differences in the effect of Hg levels on hair on users of cosmetics whitening cream and non-.cosmetic User whitening cream (pvalue 0,000), the effect on the volume of Hg levels (pvalue 0,000), no influence on the frequency of Hg ( p value of 0.000), there is the influence of the duration of use of the Hg value of 0.001, while not influential, namely age, the form of cosmetics whitening cream and the complaints of users whitening cream against level Hg, given the presence of metal brand uri contained in the whitening cream sample, it is expected that users of cosmetics whitening cream should be more careful in choosing whitening cosmetics.

“…A number of investigations on the analysis of ethanol, 1,2‐propanediol, and glycerol have been conducted using enzymatic methods and near‐infrared and 1 H NMR spectroscopies. Chromatographic techniques on the analysis of ethanol, 1,2‐propanediol, and/or glycerol in various samples have been also reported by using GC with flame ionization detector or mass spectrometer and HPLC with UV detector , refractive index detector , or mass spectrometer . Direct GC methods were coupled with thermal desorption or headspace solid‐phase microextraction systems , while indirect GC methods involved precolumn derivatization to increase volatility of analytes .…”

“…Direct GC methods were coupled with thermal desorption or headspace solid‐phase microextraction systems , while indirect GC methods involved precolumn derivatization to increase volatility of analytes . The HPLC methods with UV detector needs precolumn derivatization because of a lack of chromophore in alcohol molecules and the measurement accuracy for refractive index detection was reduced by ingredients co‐eluted .…”

We developed a reversed-phase high-performance liquid chromatography method with ultraviolet detection using on-line complexation with Cu(II) ion for analysis of five alcohols including diols and triol (methanol, ethanol, 1,2-propanediol, 1,3-propanediol, and glycerol). The Cu(II) ion concentration in the mobile phase had a great influence on the peak areas of these alcohols, but not on their retention times. Column temperature (25-40°C) and pH of the mobile phase did not affect the separation of analytes. The optimum separation conditions were determined as 5 mM CuSO , 3 mM H SO , and 3 mM NaOH at 30°C. The ratio of the peak areas for three alcohols (methanol, 1,2-propanediol, and glycerol) was in good agreement with that calculated from the obtained stability constants, molar absorption coefficients for the 1:1 Cu(II) complexes with the three alcohols, and the injected molar quantities. This fact strongly suggests that the observed high-performance liquid chromatography signals resulted from formation of the 1:1 Cu(II)-alcohol complexes. Using the proposed method, these five alcohols in spirit, liquid for electronic cigarette, mouthwash, and nail enamel remover samples were successfully analyzed with only a simple pretreatment.

“…Lot of work has been reported on the analysis of different types of cosmetic products such as lipsticks , eye products (eye shadow, black eye pencil, kajal) , lip glosses , creams , and cosmetic powders using infrared spectroscopic techniques. To the best of author’s knowledge, only one article (Gordon and Coulson, 2004) has been published regarding the identification and differentiation of foundation samples as forensic evidence.…”

Cosmetic foundation creams are encountered as evidentiary material in criminal investigations, particularly in cases related to sexual and physical assault against women. Analyzing foundation cream exhibit is a challenging task as the exhibit is recovered in trace quantity with similar hue. In the present study, ATR FTIR spectroscopy which is a rapid, nondestructive, sensitive, reliable, and safe alternative to other analytical techniques has been used to differentiate 31 cosmetic foundation creams belonging to 23 different brands supported by chemometric methods such as principal component analysis (PCA) and linear discriminant analysis (LDA). The discriminating power of visual analysis is found to be 98.0%, while PCA and LDA further increased the discriminating power to 99.3% and 100%, respectively. The blind test is conducted with three unknown samples (pretended to be unknown to the analyst), which were correctly linked with their respective source. Further, the effect of substrate such as tissue paper (dry and wet) and white cotton cloth during sample analysis are also examined to simulate the actual forensic casework conditions. The stains on substrates could be identified and linked to its parent product as well. The reported method provides significant results for the differentiation of cosmetic foundation creams.
