Sodium dodecyl sulfate Usage
1, surfactants, decontamination, foaming, wetting agents, etc.
2, relatively low-level ion pair reagents, when the requirements are not high, cheaper than heptane, sodium pentane sulfonate.
3, as a raw material, modification of materials.
4, capillary electrophoresis analysis, additives, generally used as a molar solution
5, other analytical methods will also be used, such as flow column analysis.
6, Used for washing and textile, also used as toothpaste foaming agent, fire extinguishing foam liquid, emulsion polymerization emulsifier, etc.
