Product Description

Sodium dodecyl sulfate CAS 151-21-3 Water Purification Chemicals




Sodium dodecyl sulfate is a kind of anionic surfactant, belongs to the typical representative of sulfuric acid ester surfactant, SDS for short, also known AS, K12, coconut oil, alcohol, sodium sulfate, lauryl sodium sulfate, foaming agent, sales of the commodity on the market are usually white to light yellow crystalline powder, non-toxic, slightly soluble in alcohol, insoluble in chloroform, ether, soluble in water, with anionic and non-ionic complex compatibility is good, good emulsification, foaming, foaming, osmosis, decontamination and dispersion performance, a bubble rich, biodegradation is fast, but the degree of water soluble is inferior to fatty alcohol polyoxyethylene ether sodium sulfate (AES).Is not sensitive to alkali and hard water, but the stability under acid condition is inferior to general sulfonate, close to the AES, should not be heated above 95 ℃ for a long time, stimulative belongs to medium level in the surface active agent, 10% solution stimulus index is 3.3, higher than that of AES, lower than that of sodium dodecyl benzene sulfonate (LAS).Toxic LD50 is 1300mg/kg.At present and do not have evidence to prove this article has carcinogenic sex, high dose may stimulate the skin really, but in general the concentration when defending bath product serves as foaming agent to use is finite, and it is to accord with norms of each country of the world, so everybody need not worry.

Sodium lauryl sulfate is the main component of detergent.It is often used in DNA extraction to separate proteins from DNA after denaturation.It is commonly misread as sodium dodecyl sulfonate.As foaming agent, it is widely used in toothpaste, soap, bath liquid, shampoo, washing powder and cosmetics.Sodium lauryl sulfate is found in 95% of personal skin care products and household cleaning products.

Sodium dodecyl sulfate excellent decontamination, emulsification and foaming force, can be used as detergent and textile auxiliaries, also used as anionic surface active agent, foaming agent, toothpaste mine fire extinguishing agent, fire extinguisher of foaming agent, emulsion polymerization emulsifier, medical use emulsifying dispersant, shampoo and other makeup products, wool net lotion, silk wool detergent class quality fabric.Flotation agent for metal concentrate.


1. Surfactant, decontamination, foaming, wetting agent, etc

2. Lower ion pair reagents are cheaper than heptane and pentane sulfonate when the requirements are not high

3. Modification of materials as raw materials

4, capillary electrophoresis analysis, additives, generally prepared into a molar solution for use

5. Other analysis methods will also be used, such as flow column analysis.
