Sodium Octyl Sulfate
Sodium Octyl Sulfate, a high-purity anionic surfactant, is widely utilized as a wetting agent, emulsifier, and foaming agent in various industrial applications.
Description
Sodium Octyl Sulfate (CAS 142-31-4, chemical formula C8H17NaO4S) is a short-chain anionic surfactant, specifically an alkyl sulfate, derived from octanol. It presents as a white to off-white solid, typically in powder or flake form. This compound is highly soluble in water, forming clear solutions, and exhibits excellent surface-active properties. Its molecular structure, featuring an eight-carbon alkyl chain attached to a sulfate group, renders it an effective wetting agent, capable of reducing the surface tension of liquids. Furthermore, it functions efficiently as an emulsifier, stabilizing oil-in-water or water-in-oil emulsions, and as a foaming agent, producing stable foam in aqueous systems. The product's stability across a broad pH range and its good biodegradability contribute to its widespread adoption. Sodium Octyl Sulfate is recognized for its mildness compared to longer-chain alkyl sulfates, making it suitable for applications where gentler surfactant properties are desired. Its consistent performance and versatility make it a valuable ingredient in numerous industrial and commercial formulations.
Applications
Sodium Octyl Sulfate finds extensive use across several industries, particularly within the mining sector where it acts as a frothing agent in froth flotation processes to selectively separate valuable minerals from ores. Its wetting properties are also crucial in textile processing for dye leveling and fabric treatment, enhancing the penetration of dyes and chemicals. In the paint and coatings industry, it serves as an excellent dispersant and wetting agent, ensuring homogeneous pigment distribution and improved film formation. The chemical is also employed in the formulation of detergents, cleaning products, and personal care items due to its excellent foaming and emulsifying capabilities. Additionally, it is utilized in agrochemical formulations to improve the efficacy of pesticides and herbicides by facilitating their dispersion and adherence to plant surfaces.
Storage & Handling
Store in a cool, dry, well-ventilated area away from incompatible materials. Keep container tightly closed when not in use. Avoid dust formation and ensure proper ventilation. Use appropriate personal protective equipment during handling. Avoid prolonged exposure to air and moisture to maintain product integrity.
