“…Surfactant mixtures have a smaller effect on G 0 than single surfactants and a more significant impact on G 00 when comparing systems with OCNF at the same total surfactant concentration; 40 mM single surfactants vs. 20/20 mM mixtures, with the exception of CAPB/SLS mixtures, which showed little effect. The literature 56 suggests that synergism between CAPB and anionic surfactants results in lower free surfactant concentrations in their mixtures than alone, so this is unlikely to be due to free surfactant binding to the OCNFs and changing inter-fibrillar interactions. Another visible change in OCNF gel behaviour in the presence of WLMs can be seen in the deformation behaviour.…”

“…The zone of inhibition (ZoI) is a clear zone formed by the rate of diffusion of phytochemical active compounds through the agar, furthermore the Zone of Inhibition should be correlated well with MIC value (Szewczyk and Wisniewski, 2007). Referring to the observed result as mentioned in Table 1, it can be concluded that the extract of M. alternifolia coming from maceration and soxhelatin method is strongly affecting the inhibition of S, aureus, and E. coli in dosedependent manner.…”

Melaleuca alternifolia (Tea tree/MA) is a powerful antimicrobial agent that could be one of the solutions to antimicrobial resistance. The important benefit of this plant comes from its volatile oil compounds named tea tree oil (TTO). On the other hand, studies related to the use of tea tree leaf extract as antimicrobial were still limited. Therefore, an evaluation of the active compound content and antimicrobial activity of tea tree extract obtained from different extraction methods will be carried out. Thin-layer chromatography (TLC) was performed to analysis the chemical profile, the antibacterial activity of the extracts was evaluated using the Kirby Bauer method against Staphylococcus aureus and Escherichia coli, whereas the minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) was determined by broth dilution method. Based on the chromatographic profile of the extract indicated that cardiac glycosides and terpenoids could be present in maceration and soxhletation extracts. This study suggests that maceration and soxhletation yielded different bioactive compounds from MA. Extracts of MA from both method have an excellent activity to inhibit the S. aureus, and E. coli in a dose-dependent manner. Maceration extract of MA has a stronger effect against E. coli meanwhile the soxhletation extract of MA reveals to have stronger antimicrobial activity against S. aureus. The both extract even obtained from different extraction method yielded the same MIC and MBC values namely = 0.1875% against E. coli. In contrast MBC of S. aureus range from two to fourfold of the MIC, and the maceration seem to have the highest MBC value (MBC = 12%).

“…Their chain structure and head group types determine their applications. For example, the combination of anionic surfactants with non-ionic surfactants are widely used in cleaning applications , and cationic surfactants are chosen as antistatic agents, softeners, and anti-bacteria agents. , Amphoteric surfactants are used in the personal care formulation due to their low irritant property . Double chain surfactants present specific benefits in various applications, such as the enhanced oil recovery (EOR) and fabric care, thanks to their relative high packing parameter, which leads to the easier lamellar microstructure formation. , …”

Double chain surfactants present specific benefits in various applications, such as the enhanced oil recovery and fabric care due to their relatively high packing parameter, which leads to the easier formation of the lamellar microstructure. A series of double chain quaternary cationic ammonium surfactants and amphoteric surfactant (IKD-CAT DiC n , IKD-diquat DiC n with n = 11, 13, 15, and IKD-dibetaine DiC 15 ) have been designed and synthesized in Solvay. The physicochemical properties of these surfactants were studied in this work in order to understand their self-assembly during the applications. Critical micelle concentration and the lyotropic liquid crystals as a function of concentration was investigated with various techniques, such as surface tension-meter, polarizing optical microscopy, and small-angle X-ray scattering. In general, the hydrophilic group structure determines the aggregation evolution patterns and the specific phase concentration range depends on the hydrophobic chain length. A multilayer vesicle aggregation was formed at low concentration and only lamellar phase exists in the phase diagram for IKD-CAT. Besides the lamellar phase, the hexagonal and cubic phases were also observed in IKD-diquat solutions as the concentration was increased.
