Description

Disodium 2-Dodecyl 4-Sulphonatophthalate is an anionic surfactant and dye intermediate derived from phthalic acid. This compound is valued for its excellent surface-active properties, which are critical for enhancing wetting, dispersion, and emulsification in complex formulations. It is primarily sought by manufacturers in the textile, specialty chemical, and detergent industries for producing high-performance additives and colorants.

Application

• Textile Processing: Acts as a key intermediate in the synthesis of specific dyes and as a leveling agent in dye baths.
• Specialty Surfactants: Used in formulating high-performance industrial cleaners, emulsifiers, and wetting agents.
• Pigment & Dye Manufacturing: Serves as a dispersant and stabilizer in the production of organic pigments and liquid dyes.
• Chemical Synthesis: Employed as a building block or anionic component in advanced organic synthesis.
• Industrial Detergents: Incorporated into formulations for hard-surface cleaners requiring strong wetting and soil suspension.
• Paper & Leather Processing: Functions as a processing aid and dispersant in specialty chemical applications for these sectors.

Quality Control

Our production of Disodium 2-Dodecyl 4-Sulphonatophthalate adheres to stringent quality management protocols. Every batch undergoes rigorous analytical testing to ensure consistency, purity, and performance. Certificates of Analysis (COA) documenting key parameters are available upon request to support your quality assurance and regulatory compliance 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 material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product quality.
