Ovelle Cetomacrogol Cream BP (Formula A)

Product Information

A broad smeared out peak of cetomacrogol 1000 is seen on the TLC-plates and on the rods, which could be due to its chemical structure, having a molecular weight distribution of polyethylene glycol hexadecyl ethers with different levels of ethoxylation.

We have to admit though that the TLC–FID technique has its limitations: the compounds are only identified on the basis of retention times in comparison to reference standards, and the sample is being destroyed during FID detection.The technical storage or access is strictly necessary for the legitimate purpose of enabling the use of a specific service explicitly requested by the subscriber or user, or for the sole purpose of carrying out the transmission of a communication over an electronic communications network.

The peaks from left to right, with their respective scan times between brackets are: the paraffins 1 (0. To minimize these at the origin, a severe and proper cleaning procedure of the Chromarods prior to spotting is recommended. 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.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. I find that it helps to ease the itch, i apply this twice a day, in the morning and just before bed. Several mobile phases with varying degrees of polarities (Table 2) were then investigated with the aim of achieving a good separation of all the cream excipients.
