This process leads to the formation of “hot spots” with a local enhancement of the electromagnetic field, which is confirmed by a sharp increase in the intensity of the giant Raman scattering signal. These agglomerates have fundamental differences in structure and stability from agglomerates induced by electrostatic interaction.

The resulting hydrogels were stored at room temperature (<i>T</i> = 22°C) and under refrigeration (<i>T</i> = 4°C) for 12 months. The overall stability of the formulations, concerning spreadability, absorption, texture stability, and the absence of unpleasant odor, suggests that the base structure and sensory properties were not significantly affected after one year of storage at both temperatures.
