The derivatives were characterized using Fourier-transform infrared spectroscopy (FTIR), which revealed distinct stretching vibration absorption bands indicative of methyl groups. Thermogravimetric analysis (TGA) identified a dual-stage decomposition process, consistent with reported behavior for methylcellulose. Time-of-flight secondary ion mass spectrometry (TOF-SIMS) further confirmed the presence of methyl ether groups, with the H₅CO⁺ ion detected as the characteristic fragment of the methylated samples. Functional evaluations demonstrated that double-methylated cellulose derivatives exhibited a hydrophilic–lipophilic balance (HLB) of 12.7 and a surface tension of 55 dyne/cm when compared to mono or unmethylated fibers. Additionally, the double-methylated derivatives displayed enhanced foaming activity, emulsion stability, and water solubility.

The phase transition temperatures were determined using differential scanning calorimetry (DSC). The liquid crystal phases formed in the region of high surfactant concentration were initially investigated using polarized optical microscopy (POM), and the types of liquid crystal phases were further characterized using small-angle X-ray scattering (SAXS). Finally, the rheological behavior of different phase states was studied by varying the concentration and temperature. The results show that the mixed systems of PCG and soaps exhibit rich phase behavior, and the liquid crystal phases exhibit hexagonal and lamellar phase liquid crystals. The type of soap and the compounding ratio both affect phase behavior, specifically in terms of the extent of the phase region.
