Description

Buteth-3 Carboxylic Acid is a specialized organic acid ester, a key intermediate in the synthesis of high-performance surfactants and emulsifiers. This compound matters for its unique balance of hydrophilic and lipophilic properties, enabling the formulation of stable and effective products across demanding industrial applications. It is primarily needed by manufacturers in the personal care, agrochemical, and coatings industries seeking to enhance product performance and stability.

Application

• Surfactant Intermediate: A crucial building block for the synthesis of non-ionic and anionic surfactants used in detergents and cleaning formulations.
• Personal Care Emulsifier: Used in the production of emulsifiers for creams, lotions, and other cosmetic products requiring fine, stable emulsions.
• Agrochemical Adjuvants: Serves as a component in the manufacture of wetting agents, dispersants, and emulsifiers for pesticide and herbicide formulations.
• Coatings & Inks: Acts as a dispersing aid and flow modifier in water-based and solvent-based coating systems.
• Polymer Modification: Employed as a reactive intermediate or plasticizer component in specialty polymer synthesis.
• Industrial Lubricants: Used as an additive precursor to improve the stability and performance of synthetic lubricants and metalworking fluids.

Quality Control

Our Buteth-3 Carboxylic Acid is produced under a stringent quality management system. Every batch undergoes rigorous analytical testing to ensure consistency, purity, and compliance with agreed specifications. Certificates of Analysis (COA) documenting key parameters such as assay, acid value, 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 away from strong acids, bases, and oxidizing agents. Recommended storage temperature is between 15°C and 25°C. Keep container tightly sealed when not in use to minimize moisture absorption and degradation.
