Sodium dodecyl sulfate (SDS) or sodium lauryl sulfate (SLS), sometimes written sodium laurilsulfate, is an organic compound with the formula CH 3 (CH 2) 11 OSO 3 Na and structure H 3 C−(CH 2) 11 −O−S(=O) 2 −O − Na +. It is an anionic surfactant used in many cleaning and hygiene products.

Sodium dodecyl sulfate (SDS) surfactants form micelles when dissolved in water. These are formed of a hydrocarbon core and hydrophilic ionic surface. The small-angle neutron scattering (SANS) technique was used with deuterated water (D2O) in …

May 1, 2024 · CHELPG, Merz-Kollman, and CM5 methods indicated a high negative charge distribution producing a strong affinity for water. The hydrophilicity of SDS surfactant was evaluated using different charge distributions derived from atomic charges obtained by quantum mechanical calculations.

May 1, 2024 · Simulations demonstrated that the high interfacial activity of the SDS surfactant is associated with the high negative charge distribution defined for the hydrophilic headgroup of the surfactant, which enhances the ability to attract water molecules and the solvation of the hydrophilic region.

Feb 1, 2020 · The effects of hydrochloric acid and heavy metal ions addition on surface activity of the systems containing the SDS surfactant (water – SDS, HCl – SDS; HCl – M(II) – SDS where M(II) – Cu(II), Co(II), Ni(II), Zn(II)) were presented.

Moreover, we demonstrated that the SDS surfactant aggregates to form a membrane-like structure and induces global unfolding in the protein conformation at high temperatures. This study demonstrates that maintaining the hydration shell plays an important role in the unfolding mechanism of ubiquitin.

Nov 6, 2015 · When SDS is added to water, the interfacial water molecules can form hydrogen bonds with the headgroups of the surfactant SDS molecules. This reduces the surface tension of the water solution from 72 to 39 mN/m for sufficiently high concentrations at …

Apr 8, 2024 · Molecular dynamics simulations were carried out to investigate the effect of TX-100 surfactant on the interfacial activity of ionic surfactants SDS, CTAB and SDBS at the air/water interface.

Jan 7, 2022 · Thus, cheap and fast methods are needed to detect this surfactant in wastewater and surface waters in order to prevent the negative effects of SDS on the environment and human beings.

oil/water system such as bulk n-hexadecane in contact with bulk water, the surfactant sodiumdodecylsulfate (SDS) will reduce the interfacial tension from 52 mN/m to 10 mN/m by populating the
