Description

2-Dodecylbenzenesulfonate is an anionic surfactant belonging to the linear alkylbenzene sulfonate (LAS) family, valued for its excellent detergency and foaming properties. This compound is a key intermediate and active ingredient in the formulation of high-performance industrial and institutional cleaning products. It is primarily required by manufacturers in the detergent, personal care, and specialty chemical industries seeking reliable raw materials for surfactant systems.

Application

• Primary surfactant in the manufacture of heavy-duty laundry detergents and powder cleaners.
• Key foaming and cleaning agent in industrial & institutional (I&I) cleaners for hard surface cleaning.
• Raw material for producing specialty surfactants and sulfonic acid derivatives.
• Intermediate in the synthesis of other anionic surfactants for personal care formulations such as shampoos and body washes.
• Emulsifier and wetting agent in various agricultural adjuvant and pesticide formulations.
• Component in textile processing aids and leather auxiliaries for scouring and wetting.

Quality Control

Our 2-Dodecylbenzenesulfonate is produced under a stringent quality management system. Each batch undergoes comprehensive analytical testing to ensure consistent purity, composition, and performance characteristics. Certificates of Analysis (COA) documenting key parameters such as assay, active matter content, and impurity profile are available upon request 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 at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to minimize moisture absorption, which can affect product quality.
