Sodium dodecyl sulfate, K12 powder, emulsified foaming detergent additive
Sodium dodecyl sulfate (K12) is a common anionic surfactant with functions such as emulsification, wetting, dispersion, and solubilization. The chemical formula of K12 is C12H25OSO3Na, with a molecular weight of 288.38. There are two main methods for preparing K12: sulfation and oxidation. K12 has low toxicity, but excessive use may cause harm to human health and the environment.

Product characteristics of sodium lauryl sulfate
Sodium dodecyl sulfate has good emulsifying properties, foaming properties, water solubility, biodegradability, alkali resistance, hard water resistance, and stability, easy synthesis, and low cost in aqueous solutions with wide pH values. It has been widely used in cosmetics, detergents, textiles, papermaking, lubrication, pharmaceutical, building materials, chemical, oil extraction, and other industries. It can also be used in the properties of positive and negative ion surfactant complex systems Basic research areas such as micelle catalysis and molecular ordered assemblies.
Product function of sodium lauryl sulfate
1. It is used as detergent and textile auxiliary, as well as toothpaste foaming agent, mine fire extinguishing agent, lotion polymerization emulsifier, wool detergent, etc.
2.Used as an anionic surfactant, emulsifier, and foaming agent
3.Used as an emulsifier for drugs, cosmetics, and synthetic resins.
4.Sodium dodecyl sulfate is a commonly used ionic descaling agent used in biochemical analysis, electrophoresis, ion pair reagents, and detergents. It can cause cell membranes to collapse, bind with the hydrophobic portion of membrane proteins, and separate them from the membrane. High concentrations of SDS can also break non covalent bonds such as ionic and hydrogen bonds in proteins, and even alter protein conformation.
Storage and transportation precautions
Store in a cool and ventilated warehouse. Stay away from sparks and heat sources. It should be stored separately from oxidants and avoid mixing. Equip corresponding types and quantities of fire-fighting equipment. The storage area should be equipped with appropriate materials to contain leaked materials.
