4. Medicine
Pharmaceutical excipients. Use as emulsifier, wetting agent, water-soluble lubricant.
As a lubricant, lubricating effect is lower than stearic acid metal salt, however, sodium lauryl sulfate is a soluble lubricant, it can promote disintegration and drug dissolution rate.
With the compounding of stearic acid salts (such as: magnesium stearate) and sodium lauryl sulfate by a reasonable ratio, the tablet may achieve the right balance between lubricating effect and disintegration performance.
It should be noted sodium lauryl sulfate can not be applied to human intravenous formulations.
5. Fire extinguishing agent
Use as foaming agent.
For example, U.S. Patent 6,740,250 (Fire suppressant having foam stabilizer) describes a fire suppressant having foam stabilizer.
6. Water treatment
Foaming agent, floating agent in wastewater treatment.
For example, wastewater treatment commonly uses physical and chemical process (coagulating sedimentation or flotation) in printing and dyeing industry.
Physical and chemical process is a mature technology. The process operates simply and costs cheaply.
In the coagulating sedimentation or flotation process, aluminum coagulant is one of the most widely used coagulants; magnesium coagulant is widely concerned because of green safety.
Sodium lauryl sulfate has good foaming property and water solubility. At the same time, sodium lauryl sulfate has good stability in a wide pH range.
So sodium lauryl sulfate is very suitable for use as floating agent in flotation process.
7. Emulsion polymerization
Emulsifier, particle size controlling agent in emulsion polymerization. For example, polyvinyl chloride emulsion polymerization.
8. Ore-dressing
Use as foaming agent, floating agent.
9. Textile, leather
Use as emulsifier, foaming agent, cleansing agent, wetting agent, antistatic agent, solubilizing agent.
10. Electroplating industry
Use as wetting agent (Anti-pinhole agent).
Can reduce or eliminate pinholes.
