Description

Sodium Octacosyl Sulphate is a high-molecular-weight anionic surfactant derived from a long-chain fatty alcohol. This compound is valued for its excellent emulsifying, wetting, and dispersing properties in demanding formulations. It serves as a critical functional additive for industrial manufacturers, particularly in sectors requiring stable emulsions and surface activity in non-aqueous or high-salt environments. Key industries that utilize this specialty chemical include agrochemicals, textile processing, and advanced material synthesis.

Application

• Agrochemical Formulations: Acts as a primary emulsifier and wetting agent in pesticide and herbicide concentrates (EC, SC formulations).
• Textile Processing: Used as a scouring agent, dye leveling agent, and softener component for synthetic and natural fibers.
• Industrial Cleaners & Degreasers: Provides effective emulsification of oils and fats in heavy-duty cleaning products.
• Polymer & Resin Production: Functions as an emulsifier in emulsion polymerization processes for synthetic rubbers and plastics.
• Leather Processing: Employed in fatliquoring and dyeing stages to improve penetration and uniformity.
• Paper & Pulp Industry: Serves as a dispersant and processing aid in coating and sizing applications.
• Metal Working Fluids: Enhances the stability and lubricity of coolants and drawing compounds.
• Research & Development: Used as a model long-chain surfactant in academic and industrial R&D for studying surface phenomena.
