Effect of different concentrations of sodium dodecyl
This paper describes the chemical deproteinization process of natural rubber latex (NRL) using chemical denaturants namely urea and sodium dodecyl sulfate (SDS). Commercial high ammoniated natural rubber latex (HANRL) was incubated with both denaturants urea and SDS for selected period of time before centrifugation and characterization.

Critical micelle concentration
SDSPAGE (sodium dodecyl sulfate–polyacrylamide gel electrophoresis) is a variant of polyacrylamide gel electrophoresis, an analytical method in biochemistry for the separation of charged molecules in mixtures by their molecular masses in an electric field. It uses sodium dodecyl sulfate (SDS) molecules to help identify and isolate protein

Effect of counter ion concentration added with mixture of
of sodium dodecyl sulfate in water, at the same counter ion concentration. Since the Krafft temperature of sodium dodecyl sulfate is higher in 10% ethylene glycol than in water at the same counter ion concentration, it has been concluded that the polarity of the solvent plays an important role in increasing the Krafft temperature of sodium dodecyl

Temperature and concentration dependence of properties
Sodium dodecyl sulfate (SDS) micelle heavy water solutions were studied by using smallangle neutron scattering in a wide range of surfactant concentrations ( mol/dm 3) and of temperatures (2060C). A simple model is proposed to describe the concentration and temperature dependence of average aggregation number.
