Description

2,5-Dihydroxy-4-Hexadecylbenzenesulfonic Acid Sodium Salt is a specialized anionic surfactant and intermediate with a unique phenolic structure. This compound matters for its dual functionality, combining the surface-active properties of a sulfonate with the chelating and antioxidant potential of a hydroquinone derivative. It is primarily needed by formulators in the personal care, industrial cleaning, and specialty chemical synthesis sectors seeking multifunctional additives.

Application

• Personal Care Formulations: Acts as a gentle surfactant, emulsifier, and potential antioxidant in high-end skin cleansers, shampoos, and creams.
• Industrial & Institutional (I&I) Cleaners: Serves as a key surfactant and dispersant in heavy-duty degreasers, metal cleaners, and hard surface detergents.
• Textile Processing: Used as a wetting agent, dispersant, and leveling agent in dyeing and finishing processes.
• Polymerization & Emulsion Stabilization: Functions as an emulsifier and stabilizer in the production of specialty polymers and latexes.
• Oilfield Chemicals: Employed as a component in drilling mud formulations and demulsifiers due to its surfactant properties.
• Chemical Synthesis: Utilized as a building block or intermediate for synthesizing more complex surfactants and specialty organic compounds.

Quality Control

Our 2,5-Dihydroxy-4-Hexadecylbenzenesulfonic Acid Sodium Salt is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing assay, impurity profile, and physical specifications is provided with each shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and easily oxidized; containers must be kept tightly sealed after opening to minimize exposure to air and moisture.
