Comparing the performances of different sulfonating agents in sulfonation of methyl esters synthesized from used cooking oil Tenside Surfactants Deterg. (IF 1.0) Pub Date : 2023-06-16 Adeyinka S. Yusuff, Favour B. Bode-Olajide
Methyl ester sulfonate (MES) is considered as an efficient and novel surfactant used as main active ingredient in cleansing products. MES is often produced via sulfonation of methyl ester (ME) with sulfonating agent. In this study, ME was synthesized from used cooking oil (UCO) via transesterification and then sulfonated to produce MES using two different sulfonating agents (chlorosulfonic acid (CSA)

Synthesis of non-ionic surfactants nano-vesicles for clarithromycin oral delivery Tenside Surfactants Deterg. (IF 1.0) Pub Date : 2023-06-14 Imdad Ali, Sarzamin Khan, Samrein Ahmed, Serab Khan, Heyam Saad Ali, Raiz Ullah Shafiullah, Muhammad Raza Shah, Zafar Ali Shah
In order to improve the solubility and bioavailability of poorly water-soluble drugs, the synthesis of cost-effective nonionic surfactants has been the subject of greater scientific interest. The present study focuses on the synthesis of sulfonyl chloride derivatives as nonionic surfactants (surfactant 1 and surfactant 2) and their evaluation for the preparation of a clarithromycin-loaded niosomal

Kinetic study of Ru(III) – catalyzed oxidation of L-phenylalanine by hexacyanoferrate(III) in an anionic surfactant medium Tenside Surfactants Deterg. (IF 1.0) Pub Date : 2023-06-12 Abhishek Srivastava, Ruchi Singh, Neetu Srivastava, Radhey Mohan Naik
The kinetic investigation of Ru(III) promoted oxidation of L-phenylalanine (L-PheAla) by [Fe(CN)6]3− has been performed in anionic sodium dodecyl sulfate (SDS) micellar medium by recording the decrease in absorbance at 420 nm corresponding to [Fe(CN)6]3− using an UV–visible spectrophotometer. Using the pseudo-first-order condition, the course of the reaction was studied as a function of [Fe(CN)6 3−]

Felodipine-loaded Spanlastics: superior nanocarriers for transdermal delivery Tenside Surfactants Deterg. (IF 1.0) Pub Date : 2023-06-08 Richa Mahesh Natekar, Cleona Elizabeth Mary DCruz, Lalit Kumar, Prashant Jivaji Bhide, Rupesh Kalidas Shirodkar
Felodipine is a dihydropyridine calcium channel blocker commonly used for the treatment of mild to moderate hypertension and angina pectoris. Felodipine undergoes extensive hepatic first pass metabolism resulting in low oral bioavailability of 15 %. The aim of this study is to develop a formulation of nanovesicular Spanlastics to improve the transdermal delivery of felodipine and solve the problem

Effects of surfactants and enzymes on the direct determination of protein on fabric using the BCA reaction Tenside Surfactants Deterg. (IF 1.0) Pub Date : 2023-06-07 Mai Tsukazaki, Miyuki Morita, Yuji Yoneyama
A simple and direct determination method for protein on fabric by measuring the surface reflectance of the bicinchoninic acid (BCA) reaction color has been reported. This study investigated the effects of four synthetic surfactants, six sodium fatty acids and one enzyme, as the coexisting substance on the direct determination of protein in cotton fabrics. The influence of the coexisting substance to

CuCl2-modified ionic liquids for alkylation of benzene with 1-dodecene Tenside Surfactants Deterg. (IF 1.0) Pub Date : 2023-06-07 Yarou Yang, Xu Li, Jinxiang Dong
Benzene and 1-dodecene are often alkylated to produce linear alkylbenzene (LAB). LAB is the raw material for the production of linear alkylbenzene sulfonate (LAS), a very important anionic surfactant used in both industrial cleaning and commercial laundry processes, as well as in household laundry detergents. In the present study, we investigated the use of [Et3NH]Cl–2AlCl3 modified with CuCl2 as a

Single batch co-production of Pseudomonad polyhydroxybutyrate and rhamnolipids on wasted cooking oil under salinity stress Tenside Surfactants Deterg. (IF 1.0) Pub Date : 2023-06-07 Zulfiqar Ali Raza, Muhammad Rizwan Tariq
Polyhydroxyalkanoates (PHAs) are emerging biodegradable bioplastics, and rhamnolipids are sustainable biosurfactants; both are considered as alternatives to synthetic petroleum-based plastics and surfactants, respectively. Herein, the effects of three distinct nitrogen sources on PHAs and rhamnolipid yields during the fermentation process have been undertaken. The study focuses on the optimum co-production

Surface and foaming properties of an anionic CO2-switchable tail surfactant Tenside Surfactants Deterg. (IF 1.0) Pub Date : 2023-06-05 Robin R. Benedix, Hailey Poole, Diana Zauser, Natalie Preisig, Philip G. Jessop, Cosima Stubenrauch
CO2-switchable materials in general and CO2-switchable surfactants in particular are of great interest in environmental research. There is a great potential to make processes more environmentally friendly by enhancing reusability and circularity and thus reducing material costs and energy consumption by replacing common non-switchable surfactants with their switchable counterparts. Inspired by this

Study on the properties of amide Gemini surfactants Tenside Surfactants Deterg. (IF 1.0) Pub Date : 2023-05-03 Yongchen Cai, Hujun Xu, Peng Ling
In this study, the properties of amide Gemini surfactants (DLP-12, DLP-14 and DLP-16) were investigated. The results showed that these surfactants have good wettability and solubility, but these properties deteriorate with increasing hydrophobic chain length. The critical micelle concentrations (CMC) measured by the Wilhelmy method and by the steady-state fluorescence spectroscopy were similar and
