Moisture Retention of Glycerin Solutions with Various Concentrations: A Comparative Study
This 2022 study evaluated the moisture-retention capacity of glycerin solutions at concentrations ranging from 0% to 100% using gravimetric analysis, transepidermal water loss (TEWL) assessment, and differential scanning calorimetry (DSC). Results indicated that moisture retention improved with increasing glycerin concentration up to 60%, with minimal weight change observed between 60%
