Micelle formation in the solutions oxyethylated glycerol and combined medias on their base
Abstract
The micelle formation in the cryoprotectant solutions based on (or which is based on) the oxyethylated glycerol derivatives with polymerization rate of n=5 and n=25 (OEGn=5, OEGn=25) as well as the micelle formation in the combined medias with dimethylacetamid (DMAC) have been investigated. The critical micelle concentration (CMC) of OEGn=5, OEGn=25 solutions and combined medias on their base have been assessed with stalagmometric method. It has been shown that the increasing of glycerol polymerization rate from n=5 to n=25 leads to the CMC growth at the expense of the enhancing of the compounds’ hydrophilicity. The CMC decrease as a result of mixed micelles formation in the combined medias of DMAC with OEGn=5 and OEGn=25.
