“…The LlF consists of two phases, such as waterin-oil or oil-in-water dispersions, in which surfactants can be added in order to inhibit the coalescence of the dispersed droplets. [57][58][59] The morphology of the droplets is strictly connected to two parameters: a) the flow rate and b) the chip design. 60,61 Thanks to the appropriate mixing efficacy, mass transfer and quick heat in LlF systems, NPs with a variety of shapes can be synthesized in these systems.…”

“…Due to low toxicity and easy biodegradation (Singh et al, 2006), amine oxide surfactants have been widely used, especially in detergents, showing good foaming properties. For example, a high concentration surfactant formulation with high‐surface activity and low viscosity for detergents and cosmetics can be obtained by properly designing branched‐tailed amine oxide surfactants (Fabozzi et al, 2019; Savignano et al, 2021). In addition, amine oxide surfactants are often used in combination with anionic surfactants to improve the performance of pure surfactants through synergistic effects (Khodaparast et al, 2021; Safonova et al, 2006; Wolf et al, 2009).…”

In this paper, two kinds of long-chain amine oxide surfactants, erucamidopropyl dimethylamine oxide (EAOS) and oleamidopropyl dimethylamine oxide (OAOS) were synthesized and compounded with different mass ratios. The rheological tests show that there is a synergistic effect between EAOS and OAOS, and this effect reaches the strongest at the EAOS/OAOS solution with α = 0.7 (α is the mass fraction of EAOS in the mixed surfactant). Through the synergistic effect between EAOS and OAOS, the temperature resistance of amine oxide surfactant solutions can be effectively improved. EAOS/OAOS (α = 0.7) solutions with total surfactant mass fractions of 3, 4, and 5 wt% show good high-temperature resistance at 130, 140, and 150 C, respectively. After shearing for 60 min at 100 s À1 , 160 C, the remaining viscosity of the 5 wt% EAOS/OAOS (α = 0.7) with 1 wt% KCl solution is 30 mPa s, meeting the demand of viscoelastic surfactant fracturing fluids.

“…In particular, nonionic polymers containing hydrophobic blocks formed by polymers of amino and hydroxy acids are of great interest since their decomposition leads to the formation of non-toxic, water-soluble oligomers and natural metabolic products [8]. Currently, the most fully studied biodegradable polymeric surfactants have a linear structure, although branched surfactants can have advantages in a number of properties and areas of application [6,[9][10][11][12]. Unfortunately, there is currently insufficient experimental data for the targeted synthesis of branched polymeric surfactants with desired properties.…”

In this study, new biodegradable and biocompatible amphiphilic polymers were obtained by modifying the peripheral hydroxyl groups of branched polyethers and polyesters with organosilicon substituents. The structures of the synthesized polymers were confirmed by NMR and GPC. Organosilicon moieties of the polymers were formed by silatranes and trimethylsilyl blocks and displayed hydrophilic and hydrophobic properties, respectively. The effect of the ratio of hydrophilic to hydrophobic organosilicon structures on the surface activity and biological activity of macromolecules was studied, together with the effect on these activities of the macromolecules’ molecular weight and chemical structure. In particular, the critical micelle concentrations were determined, the effect of the structure of the polymers on their wetting with aqueous solutions on glass and parafilm was described, and the aggregation stability of emulsions was studied. Finally, the effect of the polymer structures on their antifungal activity and seed germination stimulation was examined.
