Experimental and thermodynamic analysis of mixed micelles formed by dodecylethylmethacrylatedimethylammonium bromide and tetradecyltrimethylammonium bromide
(Elsevier Science, 2021-04-05)
The micellization process of a surfactant system formed by the mixture of two cationic surfactants, a conventional one, tetradecyltrimethylammonium bromide (TTAB), and a polymerizable surfactant, methylammonium ...
Preparation of polymeric micelles for use as carriers of tuberculostatic drugs

The aqueous cationic system sodium undecenoate-dodecyltrimethylammonium bromide at low concentration
(Springer, 2004-04)
The aqueous sodium undecenoate (SUD) -dodecyltrimethylammonium bromide (DTAB) catanionic system was studied at low concentration. The system did not precipitate, even at a 1:1 SUD:DTAB proportion, but showed the formation ...
Intermediate structures for higher level arrangements: catching disk-like micelles in decane phosphonic acid aqueous solutions
(American Chemical Society, 2013-04)
It has been proposed that disk-like micelles may be precursors to the formation of lamellar liquid crystals. The possibility of obtaining n-decane phosphonic acid (DPA) disklike micelles in aqueous solution without the ...
A new insight about pharmaceutical dosage forms for benzathine penicillin G
(2006-12-01)
In this work, a micellar system of benzathine penicillin G (BPG) in sodium deoxycholate (NaDC) was developed and evaluated physicochemically. The solubility profile of the drug in water and buffer solutions at various pH ...

Synthesis and characterization of 3,6-O,O’- dimyristoyl chitosan micelles for oral delivery of paclitaxel
(2017-04-01)
The aim of the present study was to investigate the potential application of 3,6-O,O’- dimyristoyl chitosan DMCh, an amphiphilic derivative of chitosan, for improving the oral bioavailability of paclitaxel (PTX), a water ...
Salt-induced sphere-to-disk transition of octadecyltrimethylammonium bromide micelles
(Amer Chemical Soc, 1998-03-31)
We have used surface tension measurements, differential scanning calorimetry (DSC), dynamic light scattering (DLS), and cryo-transmission electron microscopy (cryo-TEM) to investigate the dynamic and structural behavior ...
Rhamnolipids Production by a Pseudomonas eruginosa LBI Mutant: Solutions and Homologs Characterization
(Carl Hanser Verlag, 2014-09-01)
This paper evaluates the effect of additives (NaCl and ethanol) on the solution properties of rhamnolipids. The properties are the surface activity, aggregate formations and emulsifying activity as well as the synergistic ...
