    Abstract:

    Summary Background  Atopic dermatitis is a disease of skin barrier dysfunction and outside stimuli can cross the skin barrier. Objectives  To examine a new method for evaluating the outside to inside skin transparency with a colorimeter and yellow Dyes. Methods  In study 1, a total of 28 volunteer subjects (24 normal and four with atopic dermatitis) participated. After provocation with yellow Dye, the skin colour of all the subjects was measured using a colorimeter. The skin transparency index was calculated by the changes of the skin colour to yellow. Other variables of skin function, including transepidermal water loss (TEWL) and stratum corneum hydration, were also measured. In study 2, the skin transparency index was evaluated for a cohort of 38 patients with atopic dermatitis, 27 subjects with dry skin and 29 healthy controls. Results  In study 1, the measurement of skin colour (b*) using tartrazine showed good results. There was a significant relationship between the skin transparency index with tartrazine and the atopic dermatitis score (P = 0·014). No other measurements of skin function, including the TEWL, were correlated. In study 2, the skin transparency index score obtained with tartrazine in the patients with atopic dermatitis was significantly higher than that of the controls and those with dry skin (P < 0·001 and P = 0·022, respectively). However, the TEWL in patients with atopic dermatitis was not significantly higher than that of patients with dry skin and the TEWL in subjects with dry skin was not higher than that of the controls. Conclusions  This method, which used a colorimeter and Food Dye, is noninvasive, safe and reliable for the evaluation of out–in skin transparency and can demonstrate the characteristic dysfunction in the skin barrier in patients with atopic dermatitis.

  • effect of ph on the adsorption of sunset yellow fcf Food Dye into a layered double hydroxide caal ldh no3
    Chemical Engineering Journal, 2013
    Co-Authors: Beatriz Nogueira Cunha, Liliane M Nunes
    Abstract:

    Abstract Effluents that are discarded by Food industries are important sources of water pollution because they can contain large concentrations of organic matter and have intense color. The “batch” method for evaluating the adsorption of Sunset Yellow FCF Food Dye into a CaAl-LDH-NO 3 layered double hydroxide (LDH) system was investigated. The CaAl-LDH-NO 3 was coprecipitated at variable pH and characterized by X-ray diffraction, infrared spectroscopy and scan electron microscopy. Adsorption experiments were carried out as a function of pH, contact time and Dye concentration. The results showed that pH affects the adsorbent surface charge and the degree of anionic Dye dissociation. The effective pH range for Dye removal was between 4.0 and 10. Lower pH potentially causes dissolution of CaAl-LDH-NO 3 . The Langmuir equation adequately describes the equilibrium data. The best-fits showed a maximum adsorption of 398.41 mg/g or 0.88 mmol/g.
