Recyclable dynamic imine-based nonionic surfactants and potential use in postprocessing of eluted emulsions J. Surfactants Deterg. (IF 1.6) Pub Date : 2023-05-25 Xinyu Liu, Lianlian Sun, Hui Chen, Xuefeng Liu, Yinjun Fang, Yongmin Zhang
Recovery of surfactants and retrieval of hydrocarbons from eluted emulsions in surfactant-enhanced washing are essential to save useful resources and avoid secondary contamination. A novel nonionic surfactant of C6-DIB-PEG has been constructed by using a dynamic imine bond (DIB) as the linker between hexyl amine (C6-NH2) and an aromatic aldehyde modified polyethylene glycol (PEG-CHO). The results presented

Managing allergic conjunctivitis via ophthalmic microemulsions: Formulation, characterization, in vitro irritation studies based on EpiOcular™ eye irritation assay and in vivo studies in rabbit eye J. Surfactants Deterg. (IF 1.6) Pub Date : 2023-05-24 Vildan Yozgatlı, Neslihan Üstündağ Okur, Mehmet Evren Okur, Hande Sipahi, Mohammad Charehsaz, Ahmet Aydın, Timuçin Uğurlu
The purpose of this work was the development of an alternative ocular tetrahydrozoline hydrochloride (THZ) microemulsion for the management of allergic conjunctivitis. Pseudo-ternary phase diagrams were used to produce the microemulsions. For the formulation of the microemulsions, isopropyl myristate was selected as oil. Furthermore, various surfactants were applied for the determination of their suitability;

Benefits of using nonionic saccharide surfactant-based detergents for nanostructured fluids as stubborn graffiti paint remover J. Surfactants Deterg. (IF 1.6) Pub Date : 2023-05-18 Marcin Bartman, Sebastian Balicki, Lucyna Hołysz, Kazimiera A. Wilk
Examples of nanostructured fluids (NSFs) used as highly specialized “brush-on, wipe-off” detergents for the removal of graffiti coatings resistant to removal are water-in-oil nanoemulsions that have been stabilized with nonionic saccharide surfactants. Nanodetergents with safe, ecofriendly ingredients were produced using high-pressure homogenization (HPH). These ingredients included D-limonene or

Insight of molecular interactions between short-chain tetraalkylammonium bromides and cetyltrimethylammonium bromide: A spectroscopic and thermodynamic approach J. Surfactants Deterg. (IF 1.6) Pub Date : 2023-05-17 Suvarcha Chauhan, Kiran Negi
The influence of tetraalkylammonium salts, viz., tetraethylammonium, tetrapropylammonium, and tetrabutylammonium bromides (0.005, 0.010, 0.015 mol kg−1) on the micellar behavior of aqueous solutions of the cationic surfactant cetyltrimethylammonium bromide (CTAB, 0.2–2 mmol kg−1) over the 298.15–313.15 K temperature range has been studied by conductometric method. From conductivity versus surfactant
