Applications:
1. Surfactant and Detergent:
- Sodium Dodecyl Sulfate (SDS) is a widely used anionic surfactant in detergents, shampoos, toothpaste, and other personal care products. The -325 mesh particle size allows for easier dissolution in water, providing effective foam formation and dirt removal.
- SDS is commonly used in industrial cleaning agents, cosmetic formulations, and household cleaning products.
2. Laboratory and Research Applications:
- SDS is widely used in biochemical research for applications such as protein electrophoresis (SDS-PAGE), where it serves to denature proteins and provide a negative charge to molecules for separation based on size.
- It is also used to extract membrane proteins and in nanoparticle dispersion studies to stabilize colloidal dispersions.
3. Emulsifying Agent:
- SDS is used as an emulsifier in pharmaceutical formulations, helping to disperse active ingredients in emulsions, which are commonly used in creams, lotions, and ointments.
- It also stabilizes emulsions in the production of products like paints, inks, and cosmetics.
4. Foaming Agent:
- SDS’s foam-producing properties make it useful in foaming applications in industries such as oil recovery, where it aids in enhanced oil recovery (EOR) processes by reducing surface tension and increasing the mobility of oil.
- It is used in various applications in the food industry to aid in the creation of foams in beverages and other products.
5. Biocide and Antimicrobial Properties:
- SDS exhibits some antimicrobial properties and is used as a biocide in water treatment and preservative formulations.
- It is commonly used to reduce microbial growth in water systems, industrial equipment, and cleaning solutions.
6. Textile Industry:
- In the textile industry, SDS is used in fabric processing and dyeing. It helps improve the penetration of dyes and chemicals into fibers, ensuring better color uniformity and faster processing.
- It also aids in cleaning fabrics and removing oils, waxes, and other impurities from raw materials.
7. Cosmetic and Pharmaceutical Formulations:
- Due to its solubility and surfactant properties, SDS is used in cosmetic formulations like shampoos, conditioners, facial cleansers, and bubble baths. It helps cleanse the skin and hair by breaking down oils and dirt.
- In pharmaceuticals, SDS is used as a dispersing agent and solubilizer for poorly soluble active ingredients.
8. Scientific Instrument Cleaning:
- SDS is employed to clean scientific instruments and glassware, particularly in labs requiring sterilization and removal of contaminants, residues, and oils.
- It is a component of many lab-grade detergents designed for precision cleaning of delicate equipment, including microscope slides, test tubes, and laboratory glassware.
9. Insecticides and Pest Control:
- SDS is used in some insecticides and pest control formulations as an emulsifier and foaming agent. It is useful in the production of sprays and solutions designed to manage pests in agricultural settings.
10. Industrial Applications:
- In various industrial applications, SDS is used for cleaning metal parts, removal of oil and grease from industrial machinery, and surface preparation.
- It is also employed in textile, paper, and detergent manufacturing.
Summary:
Sodium Dodecyl Sulfate Micron Powder (SDS, C₁₂H₂₆O₄SNa, 99.5%+, -325 mesh) is a versatile anionic surfactant with numerous applications across industries. Its properties make it suitable for use as a cleaning agent, emulsifier, foam stabilizer, and dispersing agent. It is commonly used in personal care products, biochemical research, textile processing, and pharmaceutical formulations. The small particle size ensures quick dissolution in solutions and effective interaction with other compounds, making it a highly effective ingredient in a wide range of commercial and industrial applications.
