1, personal care products
As detergents, foaming agent, the principal component or auxiliary components widely used in toothpaste, shampoo, hand sanitizer, shampoo, and other areas of the personal care products.
In view of sodium dodecyl sulfate irritating, as the main surfactant is not recommended to use. Used as a help of surfactant, the amount should not be higher than 10% (mass fraction); When used as can and skin long-term exposure to products, is not recommended.

2, Sodium dodecyl sulfate used in household detergents
As detergents, foaming agent, the principal component or auxiliary components are widely used in washing powder, detergent, and other areas of the household cleaning products. Especially suitable for the preparation of household high foam light scale detergent.
3, industrial cleaning supplies
As detergents, foaming agent, the principal component or auxiliary components are widely used in industrial cleaning area, such as automotive cleaning agent, metal cleaning agent. Especially suitable for the need to produce high bubble cleaning process. Such as car washing, can see USP7, 552737 Waterless carwash liquid composition and method for producing the same, and so on.
4, Sodium dodecyl sulfate used in the pharmaceutical industry
Pharmaceutical excipients, used as emulsifier, water-soluble lubricant.
When used as lubricant, lubrication effect is better than stearic acid metal salt is good, but because is soluble lubricant, can promote the collapse of the tablets and drug dissolution rate.
Intravenous formulation cannot be used in the human body.
5, Sodium dodecyl sulfate used in fire extinguishing agent
Used as foaming agent. Can see USP6, 740250 Fire suppressant having terms stabilizer, etc.
6, Sodium dodecyl sulfate used in water treatment
Used as foaming agent, flotation agent.
Printing and dyeing industry, for example, usually by physicochemical method (coagulation precipitation or air float) for printing and dyeing wastewater treatment. Physical and chemical method is a kind of mature technology, simple operation management, using the low cost of printing and dyeing wastewater treatment methods.
In the coagulation sedimentation or coagulation air floatation process, aluminum salt coagulant is one of the most widely used coagulant; Magnesium salt coagulants with its green security advantages widely attention in dyeing and printing wastewater treatment.
Sodium dodecyl sulfate with good foamability, water-soluble and in wide pH in aqueous solution, with the characteristics of stability, therefore very suitable for coagulation air floatation process used as flotation agent.
7, Sodium dodecyl sulfate used in emulsion polymerization
As the emulsifier and applications such as particle size control agent.
8, Sodium dodecyl sulfate used in mineral processing
As foaming agent, flotation agent application
9, Sodium dodecyl sulfate used in textile, leather industry
As emulsifier, detergent, antistatic agent, wetting agent, foaming agent, oil solubilizer and other applications.
10, Sodium dodecyl sulfate used in electroplating industry
As a wetting agent (pinhole remover) applications, is used to reduce or eliminate pinhole.
11, Sodium dodecyl sulfate used in papermaking industry
As cooking penetrant, wastewater flocculants, such as waste paper deinking agent application.
12, Sodium dodecyl sulfate used as a reagent for the application
