These problems often occur in areas where the skin is thin, such as shins, hands or lower back, because these areas tend to lose moisture faster than other areas on the body. a) The sub-licensee is only permitted to access SNOMED CT® using this software (or service) for the purpose of exploring and evaluating the terminology. A good separation of all the cream components was obtained, even though broad peaks were still present. The buffered cetomacrogol cream did not show an extra peak in comparison to the non-buffered cream, hence, no newly formed allergen could be detected and the hypothesis regarding ‘compound allergy’ could be excluded. I have been using this cream for about a month on an area on my leg which seems to be the result of infected veins .

Chromatographic separation was performed on Chromarods S-V (silica gel, 5 μm particle size, 60 Å pore diameter), and peak detection using an FID, Iatroscan MK6 (Iatron Labs, Tokyo, Japan).

At PatientsLikeMe, where more than 120,000 patients are sharing their experiences with conditions, symptoms, treatments and more, over 700 patients report dry skin. e., liquid paraffin and white petrolatum) were viewed with long UV light (365 nm) after spraying with the reagent 8-anilino-1-naphthalenesulfonic acid ammonium salt (ANS) [ 6], giving Rf values of 0.

Spotted samples (left to right): 5µL cetostearyl alcohol (5 mg/mL) 1, 5µL cetomacrogol 1000 (5 mg/mL) 2, 5µL liquid paraffin (5 mg/mL) 3, 5µL white petrolatum (5 mg/mL) 4, 5µL sorbic acid (0. Another option could be soaking the Chromarods in concentrated nitric acid followed by rinsing with water.For this solution, 500 mg of the cream was diluted in 7 mL CH 2Cl 2 and vortexed until the cream was completely dispersed (appr.

The peaks from left to right, with their respective scan times between brackets are: the paraffins 1 (0. In the existing methodologies a (rather complicated) clean-up procedure is usually applied to the creams, because the excipients themselves may interfere in the chromatographic process.

The mobile phase of system A (Table 2), and a TLC plate with silica gel bound to a plastic carrier (Silica Gel 60F 254 plastic sheets, 20 × 20 cm; Merck) gave a good separation of all the cream excipients, as shown in Fig. You have been provided this information because we are supplying you with a paraffin-based/emollient product which is associated with a risk of fire.
