Description

Benzoic Acid, 2-Hydroxy-, 5-C>13-Alkyl Derivs., Sodium Salts is a specialized class of anionic surfactants derived from salicylic acid, offering a unique combination of detergency, emulsification, and mildness. This product matters for formulators seeking high-performance, biodegradable surfactants with excellent compatibility in a variety of aqueous and oil-based systems. It is primarily needed by manufacturers in the personal care, industrial cleaning, and textile processing industries where controlled foaming and effective surface activity are critical.

Application

• Personal Care & Cosmetics: Used as a primary or secondary surfactant in shampoos, body washes, and facial cleansers for its mildness and skin-friendly properties.
• Industrial & Institutional (I&I) Cleaners: Acts as a key component in liquid soaps, hard surface cleaners, and degreasers, providing effective detergency and emulsification of oils.
• Textile Auxiliaries: Employed in scouring, dyeing, and finishing processes as a wetting agent and emulsifier for processing oils.
• Emulsion Polymerization: Serves as an effective emulsifier and stabilizer in the production of synthetic latexes, such as acrylics and styrene-butadiene rubber (SBR).
• Agricultural Formulations: Used in the preparation of emulsifiable concentrates (ECs) and suspension concentrates (SCs) for pesticides and herbicides.
• Metal Working Fluids: Functions as a corrosion inhibitor and emulsifier in soluble oils and semi-synthetic coolants.

Quality Control

Our production of Benzoic Acid, 2-Hydroxy-, 5-C>13-Alkyl Derivs., Sodium Salts adheres to a strict quality management system. Every batch undergoes rigorous analytical testing to ensure consistency in active matter content, alkyl chain distribution, pH, and ionic character. Certificates of Analysis (COA) documenting these 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). Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which may lead to caking or reduced flowability.
