Description

Decyl Hydrogen Sulphate is an organic sulfate ester, specifically the sulfuric acid monoester of decyl alcohol. This compound serves as a versatile anionic surfactant intermediate and chemical building block, valued for its ability to impart surface-active properties and reactivity. It is primarily utilized by manufacturers in the detergent, personal care, textile, and specialty chemical synthesis industries.

Application

• Surfactant & Detergent Intermediate: Key raw material for the synthesis of sodium decyl sulfate and other anionic surfactants used in industrial cleaners, household detergents, and car wash formulations.
• Personal Care Products: Employed in the production of specialty surfactants for shampoos, bath products, and skin cleansers, where it contributes to foaming and cleansing properties.
• Textile & Leather Processing: Acts as a wetting agent, emulsifier, and dyeing assistant in textile manufacturing and leather treatment processes.
• Emulsion Polymerization: Functions as an anionic emulsifier in the production of synthetic rubbers, latexes, and acrylic polymers.
• Chemical Synthesis: Serves as an alkylating agent or sulfate donor in organic synthesis for pharmaceuticals and agrochemicals.
• Metal Processing: Used in electroplating baths and metal cleaning formulations as a wetting and leveling agent.

Quality Control

Our Decyl Hydrogen Sulphate is produced under a stringent quality management system. Each batch undergoes comprehensive analytical testing to ensure consistent purity, composition, and performance. Certificates of Analysis (COA) detailing assay, identity, and impurity profiles are available for every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area away from incompatible materials such as strong bases and oxidizing agents. Due to its nature as a strong acid/organic solvent, containers must be kept tightly sealed to prevent moisture absorption and decomposition. Recommended storage temperature is between 15°C and 25°C.
