Description

C11-15 Pareth-7 Carboxylic Acid is a non-ionic surfactant intermediate derived from a synthetic fatty alcohol ethoxylate, known for its excellent emulsifying, wetting, and dispersing properties. This compound is valued for its ability to be further modified into mild, high-performance anionic surfactants, offering a balance of detergency and compatibility in complex formulations. It is essential for manufacturers in the personal care, industrial cleaning, and textile processing sectors seeking versatile and effective raw materials.

Application

• Primary Intermediate for Mild Surfactants: Key raw material for synthesizing alkyl ether carboxylates (AKYPO® type), which are gentle, high-foaming surfactants for personal care products like facial cleansers, shampoos, and body washes.
• Industrial & Institutional (I&I) Cleaners: Used in the production of low-irritation, biodegradable cleaning agents for hard surface cleaners, dairy cleaners, and metalworking fluids.
• Textile Auxiliaries: Functions as an effective emulsifier and scouring agent in textile processing for fiber lubrication, dye leveling, and fabric preparation.
• Emulsion Polymerization: Serves as a robust emulsifier and stabilizer in the production of acrylic, vinyl acetate, and styrene-butadiene latexes.
• Agricultural Formulations: Employed as a component in pesticide and herbicide formulations to enhance wetting, spreading, and emulsion stability.
• Oilfield Chemicals: Utilized in drilling muds and enhanced oil recovery formulations for its emulsifying and demulsifying properties.

Quality Control

Our C11-15 Pareth-7 Carboxylic Acid is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent purity, composition, and performance. Key parameters such as acid value, saponification value, and hydroxyl value are verified. Certificates of Analysis (COA) documenting full specifications are available upon request for quality assurance and regulatory compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); keep containers tightly sealed to prevent absorption of atmospheric moisture. Keep away from strong acids and strong oxidizing agents.
