Description

Potassium Hydrogen 2-Octadecenylsuccinate is a high-purity, anionic surfactant derived from succinic acid and olefin chemistry. This compound is valued for its excellent emulsifying, dispersing, and wetting properties, making it a critical performance additive in demanding formulations. It is primarily sought by manufacturers in the personal care, industrial cleaning, and agrochemical sectors for its ability to stabilize complex mixtures and enhance surface activity.

Application

• Personal Care & Cosmetics: Acts as a primary or co-emulsifier in creams, lotions, and sunscreens, providing stable oil-in-water emulsions with a smooth skin feel.
• Industrial & Institutional (I&I) Cleaners: Serves as a key surfactant in heavy-duty degreasers, metal cleaners, and floor care products due to its effective wetting and soil suspension capabilities.
• Agrochemical Formulations: Used as an emulsifier and dispersant in pesticide and herbicide concentrates, improving the stability and efficacy of the active ingredients.
• Textile & Leather Processing: Functions as a wetting agent and emulsifier in dyeing baths, finishing agents, and leather fatliquoring processes.
• Paints & Coatings: Enhances pigment dispersion and stabilizes emulsion polymers in water-based paint systems.
• Oilfield Chemicals: Employed in drilling muds and production chemicals as an emulsifier and corrosion inhibitor.

Quality Control

Our Potassium Hydrogen 2-Octadecenylsuccinate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure consistent purity, composition, and performance. We provide full traceability and Certificates of Analysis (COA) are available for all shipments, detailing key parameters such as assay, moisture content, and acid value.

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); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product quality.
