Sodium dodecyl sulfate, the applicable scenarios for this product
Sodium dodecyl sulfate (SLS/SDS, CAS No.: 151-21-3) is an anionic surfactant with excellent detergency, emulsification and foaming properties, and is applicable to a wide range of scenarios. The main application areas can be divided into the following categories:
1. Daily Chemicals and Detergents
This is the most important application scenario:
* Cleaning Products: The core ingredient in laundry detergent, dishwashing liquid, and dishwashing liquid, utilizing its property of reducing surface tension to remove grease stains, and resistant to hard water (withstanding 500ppm mineralization).
* Personal Care: A foaming agent and detergent in shampoos, facial cleansers, and shower gels, capable of quickly producing rich foam.
* Oral Care: A foaming agent in toothpaste.
2. Food Industry (as a processing aid)
Complies with relevant food safety standards, mainly used as:
* Protein Emulsifier: Dry protein (limited to 1000mg/kg), frozen protein, and liquid protein (limited to 125mg/kg).
* Gelatin Foaming Agent: Used in fruit juice gummies, with a dosage not exceeding 0.5% of the gelatin weight.
* Beverage Stabilizer: Fumaric acid-acidified solid beverages and fruit juice drinks (limited to 25mg/kg).
* Oil Wetting Agent: Used in the fractionation of vegetable oils and animal fats, with a dosage not exceeding 10mg/kg.
3. Textile Printing and Dyeing Industry
Antistatic agents for synthetic fiber spinning
Dyeing auxiliaries and detergents for textile printing and dyeing
Wool cleaning agents, etc.
4. Pharmaceutical Industry
Disintegrants for tablets
Emulsifiers for ointments
Emulsifying and dispersing agents for pharmaceuticals
5. Chemical and Materials Synthesis
Polymerization reactions: Emulsifiers for vinyl chloride emulsion polymerization, dispersing agents for suspension polymerization, emulsifiers for synthetic rubber polymerization
Building materials: Gypsum board, concrete additives, coatings, etc.
Plastic demolding and lubrication
6. Oil Extraction and Mineral Processing
Flotation agents: Used in metal mineral processing (e.g., flotation of sodium nitrate, sodium sulfate, potassium chloride, fluorite, barite, phosphates, etc.)
Collectants and foaming agents: Used in mineral processing
Emulsifiers in crude oil extraction, enhancing oil recovery
Mine fire extinguishing agents
7. Other Industrial Applications:
Paper Industry Additives; Ammonium Perchlorate Surface Desensitizer and Dispersant; Wastewater Treatment: Modified Zeolite Adsorbent Combined with SLS to Treat Hydrate Inhibitors; Product Characteristics Summary: Sodium dodecyl sulfate is a white or pale yellow powder/pellet, easily soluble in water, insensitive to alkalis and hard water, and has good biodegradability. It also exhibits good compatibility with anionic and nonionic surfactants. These properties make it an indispensable functional raw material in many industries.
