Temperature dependence of the micelle aggregation number and rate of intramicellar excimer formation in aqueous surfactant solutions

Interactions between Dyes and Surfactants in Inkjet Ink Used for Textiles

“…In contrast, our results 29 indicate that the aggregation numbers of SDS micelles decreased with increasing temperature, which is in agreement with previously reported results 32 . Similar decreases were reported for other ionic surfactants such as n-dodecylammonium chloride, n-dodecyltrimethylammonium bromide, n-tetradecyltrimethylammonium chloride, and n-hexadececyltrimethylammonium chloride 32 . In summary, the aggregation number increased with temperature for nonionic surfactants, whereas anionic surfactants showed the opposite trend.…”

“…Nonionic surfactants showed similar tendencies, as reported the previous papers 32,44 : in the temperature range from 25 to 55 , the N value of OGDE micelles increased from 96.8 to 138 44 .…”

Mixed Micellization of Dimeric (Gemini) Surfactants and Conventional Surfactants

“…It is known that an increase of T generally increases the aggregation number of nonionic micelles of the C m E n type (51) and decreases that of ionic micelles (55). When ionic and nonionic surfactants are mixed, the variation of the aggregation number of the mixed aggregates is mainly determined by the interplay of these two opposite tendencies as well as the interactions between the hydrophilic heads.…”

Small Variations in the Composition and Properties of Triton X-100

“…Many references to the properties of TX100 solutions may be found in Refs. (1,2,(8)(9)(10). The static light scattering measurements of Brown et al provided weight-averaged molecular weight of the micelles (10).…”
