Sodium dodecylbenzenesulfonate is one of a group of salts of alkylbenzene sulfonates used in cosmetics as surfactant-cleansing agents. Sodium dodecylbenzenesulfonate is soluble in water and partially soluble in alcohol, with dermal absorption dependent on pH. Dodecylbenzenesulfonate salts are not toxic in single-dose oral and dermal animal tests, and no systemic toxicities were observed in repe...

Objective: This study aimed to determine the dialyzability of common pesticide surfactants. Methods: Hemodialysis and hemoperfusion were performed for three surfactants-sodium dodecylbenzenesulfonate, lignosulfonic acid sodium, and naphthalenesulfonic acid polymer with formaldehyde-with buffer solutions (2 L) containing 0.2% surfactant with or without bovine serum albumin (3.0 g/dL). Results: T...

Adsorption kinetics and equilibrium studies of sodium dodecylbenzenesulfonate (NaDBS) on cellulosic surface are investigated. Modifications in adsorption induced by cationic surfactant cetyltrimethylammonium bromide (CTAB) are studied. It is concluded that the rate of adsorption and the amount of adsorption are increased. Importance of these observations in detergency is indicated.

Graphene and chemically modified graphenes were resolved by micellar electrokinetic chromatography (MEKC) using sodium dodecylbenzenesulfonate (SDBS) as a micelle matrix. Graphene was successfully dispersed in a micellar solution, and a consecutive and broad signal was obtained by the MEKC with a 20 mmol dm⁻³ aqueous SDBS solution for Graphene Nanoplatelets. Chemically oxidized graphene was les...

Thin fibers were spun from a colloidal solution of single-walled carbon nanotubes (SWNTs) using an electrophoretic method. Sodium dodecylbenzenesulfonate (NaDDBS) was chosen as a surfactant and showed good performance owing to its special chemical structure. The highest spinning velocity reached 0.5 mm s-1. The resulting SWNT fibers had a tensile strength of 400 MPa and a conductivity of 355 S ...

The leaching behaviors of enrofloxacin (ENR), a fluoroquinolone group antibiotic, in three different standard soils, namely sandy, loamy sand and sandy loam were investigated according to OECD guideline 312. In addition, the effects of tenside, sodium dodecylbenzenesulfonate (DBS) on the mobility of ENR in two different soils were studied. The mobility of ENR in all three standard soils was ver...
