379 CAS No.
151-21-3
.

This product is a mixture
of sodium alkyl sulfate based on sodium lauryl sulfate (C12H25NaO4S).

【Properties】This product is white to light yellow crystal or powder; There is a characteristic slight odor
.

This product is easily soluble in water and almost insoluble
in B.

【Identification】 (1) The aqueous solution of this product (1→10) shows the identification reaction of sodium salts (general rule 0301).


(2) The aqueous solution of this product (1→10) is acidified with hydrochloric acid, slowly heated and boiled for 20 minutes, and the solution shows the identification reaction of sulfate (general rule 0301).


Sodium lauryl sulfate is generally packed in plastic drums, or the lining is plastic, the outer packaging is iron, and it is stored
in a cool and dry place.

Sodium dodecyl sulfate is stable at room temperature and pressure, easy to absorb water and agglomerate in the powder state, decontamination, emulsification and foaming ability is relatively strong, biodegradability is also very good, in a wide range of pH value in the aqueous solution, is still quite stable, due to easy to synthesize, low price, sodium lauryl sulfate in textiles, cosmetics papermaking, detergents, pharmaceuticals, oil production, building materials, chemicals and other industries have a wide range of applications, but also often used to carry out surfactant compounding, micelle catalysis, Molecular ordered combinations and other studies
.

Sodium lauryl sulfate can be used as detergents, wool detergent, toothpaste foaming agent, textile auxiliary, mine fire extinguishing agent, emulsion polymerization emulsifier; In the food industry, sodium lauryl sulfate is often used as a blowing agent or surfactant; In terms of pharmaceutical paper, it is often used as an emulsifier for cosmetics and so on; In terms of biochemical analysis, it can be used as electrophoresis, ion pair reagent [use one] as detergent and textile auxiliary, but also as toothpaste foaming agent, mine fire extinguishing agent, emulsion polymerization emulsifier, wool detergent, etc
