The gelation mechanism and application to commodities of non-water gel comprising PEG
We developed a non-water gel product comprising HPC and PEG, reacting hydration with water. We investigated the gelation mechanism of HPC/PEG gel by means of a stress-controlled rheometer and an X-ray diffractometer. According to the results, the mechanism has two factors: entanglement of the HPC polymer chain and cross-linkage of the microcrystal domain of the HPC main chain. The HPC/PEG gel is useful as the basic material of the cosmetic plaster that causes skin surface temperature to rise and the blood stream to accelerate.
