SYNERGISM IN MIXED MICELLE FORMATION

Journal of Dispersion Science and Technology, 1994
ABSTRACT Synergism,β in two separate surfactant mixtures of sodium dodecylsulphate(SDS)/sodium octanoatet(NaC8) and tetradecyltri-methyl ammonium bromide(TTAB)/cetyltrimethylammonium bromide (CTAB) system were calculated and contrasted with the theoretical value at critical micelle concentration, cmc.

Mixed Micelles of Fluorinated and Hydrogenated Surfactants

Journal of the American Chemical Society, 2006
The model mixed surfactant system of sodium perfluorooctanoate and sodium decyl sulfate was carefully reexamined by a combination of nuclear magnetic resonance methods. Over a wide range of sample compositions, detailed (19)F and (1)H chemical shift data in combination with self-diffusion coefficients for the perfluorooctanoate and decyl sulfate ions ...

Mechanism of the Mixed Surfactant Micelle Formation

The Journal of Physical Chemistry B, 2010
This article provides a full description of the mixed micelle formation process at a molecular level. The mechanism of mixed micelle formation in binary surfactant aqueous solution systems, ionic/nonionic mixed systems (12-2-12/TX-100, 14-2-14/TX-100, and SDS/TX-100), and ionic/ionic mixed systems (12-2-12/TTAB, 14-2-14/TTAB, and SDS/CTAB), in heavy ...

Mixed micelles of alkylamines and cetyltrimethylammonium chloride

Journal of Colloid and Interface Science, 2005
The influence of chain length and the nature of the head group on the composition of micelles of a binary mixture of cetyltrimethylammonium chloride with both unsubstituted and N-substituted n-octyl, n-decyl, and n-lauryl amines was established from the variation of the critical micelle concentration (cmc) as a function of the solution composition.

Solubilization of n-hexanol in mixed micelles

Colloids and Surfaces, 1988
Abstract The solubilization of n-hexanol by mixed anionic/nonionic and cationic/nonionic micelles was measured throughout a wide range of hexanol activities. The solubilization equilibrium constant for both kinds of mixed micelles is less than that predicted by assuming that the equilibrium constant varies linearly with nonionic/total surfactant mole

Nonionic micelles in mixed water-glycerol solvent

Journal of Colloid and Interface Science, 1987
Abstract The aggregation properties of the nonionic amphiphile C 12 E 8 in water-glycerol mixtures are investigated at various glycerol volume fractions X by surface tension, light scattering, refractometry, and viscosimetry measurements. In the range 0 X X , and the aggregation number m decreases with X .

Nonideality of Mixing of Micelles

1986
The composition of mixed micelles and the volume change ΔV on mixing of micelles were determined from measurements of the surface tension γ and the density. For some comicellar systems of fluorocarbon and hydrocarbon surfactants, there is a plateau region in the γ vs micellar composition curve, where two kinds of mixed micelles coexist in equilibrium ...

Mixed Micelle-Template Route to Mesoporous Silica

Journal of Nanoscience and Nanotechnology, 2007
Mesoporous silica materials were prepared through a novel mixed micelle-template method which was employed by alkyl polyethylene oxide (C16E20 and C2-ceramide. X-ray diffraction patterns clearly showed the formation of mesoporous silica by contribution of mixed micelle-template up to 3/1 weight ratio (C16E20/C2-ceramide).

Fatty Acid Transfer in Taurodeoxycholate Mixed Micelles

Biochemistry, 1996
Dietary triacylglycerol is acted upon by lipolytic enzymes in the stomach and the proximal small intestine, releasing fatty acids and monoacylglycerol as the ultimate products. These digestive products are solubilized by bile released from the gall bladder, resulting in the formation of two product phases-vesicles and micelles-depending upon the ...
