N2 - The Raman technique can be used in the monitoring of molecular changes in organogel emulsions by intensity changes and band shifts. Raman spectra were obtained from individual components, then from an organogel and then from organogel emulsions. Raman bands corresponding to chemical bonds involved in intermolecular interactions were followed up. Changes Raman in mixture of lipophilic components were observed with respect to individual components and subsequently upon inclusion of an aqueous phase in emulsified systems. The organogel emulsions showed variations in Raman bands of hydrogen bonding and hydrophobic interactions. Variations in intensity ratio values of some bonds indicate modifications in the packing of the continuous phase that is affected by slight changes in surfactant concentration in time.
