Role of Moisture. After gaining the needed insights into the interactions of the surfactants in pure dodecane, we next turn our attention to the role of a vapor of water infusing into the oil phase and the ensuing stability of the aggregates thus formed. To achieve this objective experimentally, water vapor saturated air was made to bubble through dodecane with surfactants pre-dissolved in it. As time progresses, it is observed that the primary peaks of the surfactants shift towards the higher wavelengths (Figure )). The peak for DDA corresponding to 210 nm decreases, whilst that at 220 nm increases. These bathochromic shifts mark the role of water in the formation of H-bonded structures, which would be possible if the surfactants are in close proximity to each other, as would be the case if they form oil-in-water emulsions. DPD-MD simulations Figure (J to L) clearly show the possibility of the formation of water-in-oil emulsions with pure and mixed surfactants. However, these inverted emulsions exhibit different degrees of stabilities, as indicated by the ratio 𝑡 -/𝑡 + . Here, too, as is the case with dry dodecane, the mixture of the anionic and nonionic surfactants is more stable than those formed with the pure surfactants.
