However, when system A was used on the Chromarods, the paraffins (liquid paraffin and white petrolatum) and cetostearyl alcohol co-eluted while sorbic acid and cetomacrogol 1000 could not be resolved. A cream sample solution of 45.5 mg/mL was used. 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. 1 minute). Then, 4 mL of EtOH was added and the sample was vortexed again until a clear solution was obtained. It was necessary to vortex the sample solution until a(n) (almost) clear solution was reached, prior to spotting. Spotting volumes of 1µL for both the reference solutions and cream sample solutions were used. 2.4 Elution system Whitmore DA, Wheeler KP (1980) A simple method for the separation and assay of non-ionic detergents.

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). Hydrogen—and air flow were set at 160 mL/min and 2 L/min, respectively. A scan speed of 25 s was used for sample analysis. 2.2 Chemicals van Heugten AJP, Braal CL, Versluijs-Helder M, Vromans H.

Topical application of bacteriophages for treatment of wound Topical application of bacteriophages for treatment of wound

The choice of occlusive emollient depends upon the area of the body and the degree of dryness and scaling of the skin. Lotions are used for the scalp and other hairy areas and for mild dryness on the face, trunk and limbs. Creams are suitable for moderate dry skin. Ointments are recommended for very dry scaly areas, but many patients find them too greasy. Sorbolene cream is a good all-round moderate-strength moisturiser that suits many patients because it is non-greasy, cheap and available in bulk with or without prescription. Typically, 250g (or ml) to 1Kg (1l) are needed and liberal and regular usage is to be encouraged. Lake OA, Hulshoff A, Indemans AWM (1982) Analysis of creams—III.

Applications per day were analysed by analysis of variance (ANOVA) with the response variable as the mean average number of applications per day, predictor variable randomisation group, and using the number of days in the trial as a weight, to account for variations in the number of days of application.

Accessed 20 Sept 2019Due to significant differences in polarity of the components used in cetomacrogol cream, it was difficult to find a single solvent that was able to separate all target components into distinct peaks. We resorted to a two-step elution procedure, in which a relatively less polar mobile phase was used to develop the rod to a distance of 10 cm, resulting in the separation of the paraffins and cetostearyl alcohol migrating towards the top of the Chromarod into two distinct peaks, while sorbic acid and cetomacrogol 1000 remained at the origin. After drying, the Chromarod was further redeveloped up to a distance of 3 cm in a second tank containing methanol, which, being polar, was able to resolve sorbic acid from cetomacrogol 1000. At PatientsLikeMe, where more than 120,000 patients are sharing their experiences with conditions, symptoms, treatments and more, over 700 patients report dry skin. The majority rate this symptom as either “moderate” (35%) or “severe” (17%). Primary conditions representing include everything from fibromyalgia to depression, showing that this uncomfortable symptom affects all different types of patients.
