Effects of temperature and polyols on the ciprofloxacin hydrochloride-mediated micellization of sodium dodecyl sulfate

Abstract

A conductivity method was used to see effects of a ciprofloxacin hydrochloride (CFH)/CFH + polyols (organic compounds with multiple hydroxyl groups (glucose and fructose)) on aggregation phenomenon of sodium dodecyl sulfate (SDS) at 298.15–318.15 K.

Interaction of metformin hydrochloride with ionic surfactants in aqueous and NaCl solution: Effect of temperatures and compositions

“…The interaction between drugs (ciprofloxacin hydrochloride and levofloxacin hemihydrates) and cetyltrimethylammonium bromide was explored by our group in an aqueous electrolyte medium at different temperature. [ 35–37 ] In spite of the fact that there are a lot of studies involving surfactants–drug interaction in the literature, to the best of our knowledge, very little is known regarding the interaction of metformin hydrochloride (MNH) with CTAB and SDS in NaCl solution.…”

Role of carbonate electrolytes on interaction of quinolone drug with anionic surfactant at various temperatures: A conductometric study

“…m in case of singular surfactant in H 2 O were achieved positive and negative at inferior and higher temperature respectively and the negative values of ΔH o m enhance with increasing temperature. [25] The executed magnitudes of ΔH o m for individual SDS in Na 2 CO 3 and K 2 CO 3 were found to be positive at all concentrations of electrolyte at the entire temperatures investigated. On the other hand, the ΔH o m values for individual SDS in CaCO 3 were achieved negative at 1 and 5 mmolÁkg −1 CaCO 3 and positive at 3 mmolÁkg −1 CaCO 3 , whereas negative and positive at the inferior and superior temperature respectively in case of 7 mmolÁkg −1 CaCO 3 .…”

“…The κ values of the SDS/SDS + CFH mixed system were measured and recorded to disclose the behavior of SDS + CFH in the absence/existence of electrolytes following the technique stated in the literature. [25][26][27][28][29] The κ values of the target systems in the different medium were noted through a digital conductivity meter (model HI 2315 [Hanna, Germany]) keeping dip cell of cell constant = 1.0 cm −1 (delivered by the producer) and precision of about ±0.5%. The desired experimental temperature of the target systems was maintained through H 2 O stirring thermostat bath (RM6 Lauda) having an accuracy of ±0.2 K. The temperature was set in the thermostatted water bath so that the conductivity meter can display the desired temperature and the thermostat automatically changed the temperature of the bath subject to allow sometimes for attaining the desired temperature.…”

“…Formerly, calculated ΔG o m and ΔH o m values are taken in Equation 5 for the measurement of ΔS o m : [7,25,53,54] ΔS…”

“…The outcomes reveal the spontaneous micellization in every case. The values of different thermodynamic parameters for SDS/SDS + CFH in an aqueous medium already have been published in our previous article [25] and used herein for comparison purposes only.…”
