Description

1,4-Didodecyl Sulphosuccinate is a high-purity, anionic surfactant belonging to the sulphosuccinate ester class. This compound is valued for its excellent emulsifying, dispersing, and wetting properties in both aqueous and non-aqueous systems. It is a critical raw material for formulators in the personal care, agrochemical, and industrial cleaning sectors seeking stable, high-performance surfactant blends.

Application

• Personal Care & Cosmetics: Acts as a primary or co-emulsifier in creams, lotions, and sunscreens, providing stable oil-in-water emulsions with a soft after-feel.
• Agrochemical Formulations: Used as a wetting agent, dispersant, and emulsifier in pesticide and herbicide concentrates to enhance spray coverage and efficacy.
• Industrial & Institutional (I&I) Cleaners: Serves as a key surfactant in hard surface cleaners, degreasers, and emulsion cleaners due to its robust detergency.
• Textile Processing: Functions as a wetting and leveling agent in dye baths and fabric treatment processes.
• Paints & Coatings: Employed as a pigment dispersant and grinding aid to improve color development and stability in water-based systems.
• Polymerization: Can be utilized as an emulsifier in emulsion polymerization processes for synthetic rubbers and plastics.

Quality Control

Our 1,4-Didodecyl Sulphosuccinate is manufactured under a stringent quality management system. Each batch undergoes comprehensive analytical testing, including assay, identification, and impurity profiling, to ensure it meets precise specifications for purity and performance. Certificates of Analysis (COA) documenting these results are available for every shipment to guarantee traceability and compliance with your quality protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled 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.
