Anionic Surfactants and Surfactant Ionic Liquids with Quaternary Ammonium Counterions
Langmuir, 2011Small-angle neutron scattering and surface tension have been used to characterize a class of surfactants (SURFs), including surfactant ionic liquids (SAILs). These SURFs and SAILs are based on organic surfactant anions (single-tail dodecyl sulfate, DS, double-chain aerosol-OT, AOT, and the trichain, TC) with substituted quaternary ammonium cations ...

Langmuir, 2011
We present herein a study on the adsorption of anionic (SDS), cationic (CTAB), and nonionic (C(12)E(5)) surfactants onto anionic silica nanoparticles. The effects of this adsorption are studied by means of the static structure factor, S(q), and the collective diffusion coefficient, D(c), obtained from small-angle X-ray scattering and dynamic light ...

Potentiometric Sensors for the Determination of Anionic Surfactants – A Review
Critical Reviews in Analytical Chemistry, 2019Anionic surfactants are important components of many products used in everyday life in all households. They are also applied in various industrial fields at a very large scale. Since they have a negative influence on the environment, it is an imperative to monitor their concentration in aquatic ecosystems.

Anionic Surfactants—An Introduction
2019This chapter introduces the class of chemical compounds collectively known as anionic surfactants, the members of that class that have achieved major importance, and, as far as it affects the analyst, the raw materials, processes, and by-products that may be found. Surfactants are by necessity large molecules with molar masses usually in excess of 300.

Interaction of mixture of anionic surfactants with collagen
International Journal of Cosmetic Science, 2007SynopsisStudy focused on interaction of collagen fibres of collagen I with anionic surfactants sodium dodecylbenzene sulphonate (SDBS), sodium dodecyl sulphate (SDS) and their mixtures at pH = 6, at two ionic strengths (I = 0.06 mol L−1and I = 0.4 mol L−1) and laboratory temperature.

BIODEGRADATION OF THE ANIONIC SURFACTANT DIALKYL SULPHOSUCCINATE
Environmental Toxicology and Chemistry, 1993Abstract A range of Organisation for Economic Cooperation and Development (OECD) guideline test systems was used to determine the extent and possible mechanisms of biodegradation of dialkyl sulphosuccinate (DASS, C6/C8). Primary biodegradation of DASS was virtually complete in OECD guideline tests and in simulations of activated sludge ...

Journal of Surfactants and Detergents, 2001
AbstractThe effect of different alkyl chains of anionic surfactants on properties of binary anionic‐nonionic mixed surfactant systems was studied. These systems included ocytldodecyl‐, and cetylsulfoacetates mixed with isooctyl phenol nonyl ethoxylate. The critical micelle concentration of mixed surfactants shifted to lower values compared to those of ...
