Solubilization kinetics of n-alkanes by a nonionic surfactant

Solubilization kinetics of n-alkanes by a nonionic surfactant. Donegan, Ann C.; Ward, Anthony J. I. (Dep. Chem., Univ. Coll., Belfield/Dublin, Ire.). J. Pharm. Pharmacol., 39(1), 45-7 (English) 1987. CODEN: JPPMAB. ISSN: 0022-3573. DOCUMENT TYPE: Journal CA Section: 63 (Pharmaceuticals) The rates of solubilization of a homologous series of n-alkanes (CnH2n+2; n = 8-16) into micellar solns. of n-dodecyl hexaoxyethylene glycol ether [3055-96-7] were measured at 298 K. A mechanism involving a micellar dissocn.-assocn. process previously proposed an adequate description of the data. Proportionality between the micellar solubilization capacity in the kinetic process and that found at equil. could be inferred for such a series of solubilizates which have the same locus of solubilization and packing requirements.

Gel filtration of solubilized systems

Gel filtration of solubilized systems. VII. Temperature effect on the solubilization of ethylparaben in hexaoxyethylene lauryl ether micelles. Goto, Ayako; Endo, Fumio; Higashino, Takeo (Shizuoka Coll. Pharm., Shizuoka 422, Japan). Chem. Pharm. Bull., 32(8), 2905-9 (English) 1984. CODEN: CPBTAL. ISSN: 0009-2363. DOCUMENT TYPE: Journal CA Section: 63 (Pharmaceuticals) The effect of temp. on the solubilization of Et p-hydroxybenzoate (ethylparaben)(I) [120-47-8] in hexaoxyethylene lauryl ether (C12E6) [3055-96-7] micelles was examd. by the gel filtration method using Sephadex G-200. The values of std. Gibbs energy (DGq), enthalpy(DHq) and entropy (DSq) changes for the micellar solubilization of I were calcd., together with the interaction energy parameter (w). The neg. values of DHq and w showed that there is an interaction between the phenolic OH group in I and the polyoxyethylene groups in the C12E6 micellar phase. The pos. values of DSq suggest that the alkane moiety of I is incorporated into the hydrocarbon core of C12E6 micelles. These results showed that both enthalpy and entropy effects control the micellar solubilization of I.
