Description

p-[3-(Octylthio)Propyl]Benzenesulfonic Acid Sodium Salt is a specialized anionic surfactant and sulfonate compound valued for its unique combination of a hydrophobic alkyl chain and a hydrophilic sulfonate group. This structure makes it an effective emulsifier, wetting agent, and dispersant in demanding formulations. It is primarily sought by manufacturers in the polymer, agrochemical, and specialty chemical industries for applications requiring stable emulsions and surface activity.

Application

• As an emulsifier and stabilizer in the production of polymer emulsions, including acrylics, styrene-butadiene, and PVC.
• As a wetting and dispersing agent in agrochemical formulations such as suspension concentrates (SC) and wettable powders (WP).
• As a key surfactant component in industrial cleaning and degreasing formulations.
• In the synthesis of specialty chemicals and as an intermediate for further sulfonation reactions.
• As an additive in textile processing aids and dyeing auxiliaries.
• In the formulation of oilfield chemicals for demulsification and drilling mud applications.

Quality Control

Our production of p-[3-(Octylthio)Propyl]Benzenesulfonic Acid Sodium Salt adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing to ensure consistency, purity, and performance. Certificates of Analysis (COA) documenting key parameters such as assay, moisture content, and impurity profiles are available upon request to support your quality assurance and regulatory needs.

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 product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect product quality and flow properties.
