Aggregation behavior of anionic sulfonate gemini surfactants with dodecylphenyl tails

Antimicrobial and Cytotoxic Properties of Bisquaternary Ammonium Bromides of Different Spacer Length

“…Nowadays, these chemicals are among the most commonly used compounds because of their properties, determined by their amphiphilic structure and a wide utility in many industrial branches (Mao, Jiang, Xiao, & Yu, ; Ohkawa, Takada, Sakurai, Sekine, & Fukui, ; Xia & Zana, ). For the same reasons, surfactants are among the most often investigated compounds (Cardoso et al, ; Chen, Xie, Li, & Yu, ; He, Sheng, Li, & Song, ; He, Wang, Chen, Tang, & Feng, ; Hegazy, Rashwan, Kamel, & El Kotb, ; Hordyjewicz‐Baran et al, ; Nesterenko, Drelich, Lu, Clausse, & Pezron, ; Sheng, Li, Zhou, & Song, ). One of the main important attributes of cationic surfactants is their significant antimicrobial activity (Abe & Matsuki, ; Birnie, Roger, & Schnaare, ; Caillier et al, ; Colomer et al, ; Gilbert, ; Kumar & Tyagi, ; Kuperkar, Modi, & Patel, ; Tewfik, ; Tiecco, Cardinali, Roscini, Germani, & Corte, ; Tyagi & Tyagi, ; Zhang et al, ), because of which these compounds have found their applications in many biomedical products.…”

Novel Hydroxylated Cardanol Quaternary Ammonium Salts from Renewable Resource and its Synergistic Vesicles of Binary and Ternary Composite System in Detergent

“…This result shows that the fact that the micelles will undergo morphological transition from spherical or short rodlike micelles to dendritic micelles with increasing concentration ( Liu et al, 2014 ) . This is mainly because with the increasing concentration, the molecular interactions and structures of HCQAS 3a have changed, such as hydrogen bonds, ionic bonds, π‐π interactions between aromatic groups (Bao et al, 2017; Hordyjewicz‐Baran et al, 2015), the long alkoxy chain, and high dissymmetric degree, causing micelles to aggregate into different forms. In the case of a concentration 1000 times higher than the CMC value of HCQAS 3a, the abundant small spherical micelles tended to further elongate and formed long rodlike and dendritic micelles with micellar joints, resulting in the appearance of gelling behavior (Fig.…”

Recent Advances in the Synthesis of Sulfonate Gemini Surfactants

“…Sulfonated Gemini surfactants are novel surfactants with excellent properties such as high surface activity, as well as lower CMC than carboxylate and phosphate ester Gemini surfactants, which could improve the cloud point of the traditional nonionic surfactant and enhance the washing efficiency (Du, Li, Lu, & Yang, 2007;Masuyama et al, 2000). They have good compatibility with traditional anionic surfactants (Zhu, Cheng, Wang, & Yu, 2006), excellent aggregation behaviors (Hordyjewicz-Baran et al, 2015), unique rheological properties, and good salt resistance (Zhou, Xia, et al, 2015), which would be broadly applied in many areas in the future. The molecular structure of the sulfonated Gemini surfactants contains two negatively charged sulfonic groups.…”
