K12: sodium lauryl sulfate, chemical formula is C₁₂H₂₅SO₄Na, white or light-yellow powder, soluble in water, insensitive to alkali and hard water. It has decontamination, emulsification and excellent foaming power. It is an anionic surfactant that is slightly toxic to the human body, and its biodegradability is >90%.

Application field：

Sodium lauryl sulfate has good emulsification, foaming, water solubility, biodegradability, alkali resistance, hard water resistance, stability in aqueous solutions with a wide pH value, ease of synthesis, and low price. It has been widely used in cosmetics, detergents, textiles, papermaking, lubrication, pharmaceuticals, building materials, chemicals, oil production and other industries. It can also be used in the properties of positive and negative ion surfactants, micelle catalysis, and orderly combination of molecules. Basic research aspects such as physical education.
