This work investigates the processes of adsorption and micelle formation in aqueous solutions of surfactants (SAS), which determine their technological properties. Through theoretical analysis based on a method proposed in the literature, the contribution of various functional groups to the change in Gibbs free energy of these processes was assessed. The results show that the change in free energy during micelle formation can be represented as the sum of changes in energy of the hydrophilic and hydrophobic components of the SAS molecules. A linear dependence between the change in free energy and the number of hydrocarbon groups was revealed, allowing the calculation of the energetic contribution of a single hydrocarbon group. The analysis showed no direct dependence between the number of hydrophilic groups and the change in free energy, indicating that only a certain portion of these groups integrate into the micelles. The study also emphasizes the difference in the technological properties of solutions when using anionic surfactants and offers a new understanding of the thermodynamic aspects of adsorption and micelle formation processes in aqueous solutions of molecular SAS.
