As stated previously, salicylic acid (or as a precursor to the acid), sodium salicylate is produced commercially by treating sodium phenate (the sodium salt of phenol—phenol is a well-known petrochemical starting material) with carbon dioxide at high pressure (1,500 psi) and high temperature (117°C, 242°F) (the Kolbe–Schmitt reaction) after which acidification of the product with sulfuric acid yield gives salicylic acid.

The cationic surfactant used in the experiment is octadecyl trimethyl ammonium chloride (OTAC), the nonionic polymer is polyethylene oxide (PEO). Sodium salicylate (NaSal) is used as the counterion in combination with a cationic surfactant (to enhance the stability of the micelle structure and reduce the critical micelle concentration of the surfactant solution) (Liu, Wang, and Wei 2018). All the above materials are shown in Table 1. And the experimental water is distilled water.
