Description

2-Sulphopalmitic Acid CAS NO 1782-10-1 is a specialized organosulfur compound derived from palmitic acid, serving as a key intermediate in the synthesis of surfactants and specialty chemicals. Its sulfonic acid group provides excellent water solubility and surface-active properties, making it a valuable building block for performance materials. This product is essential for manufacturers in the detergent, personal care, and textile chemical industries seeking to develop anionic surfactants with specific foaming, wetting, or emulsifying characteristics.

Application

• Surfactant Intermediate: Primary raw material for synthesizing high-performance anionic surfactants and detergents.
• Personal Care Formulations: Used in the production of mild cleansing agents for shampoos, body washes, and facial cleansers.
• Textile Auxiliaries: Key component in wetting agents, scouring agents, and dyeing assistants for the textile industry.
• Industrial & Institutional (I&I) Cleaners: Building block for formulating hard-surface cleaners, degreasers, and industrial detergents.
• Emulsion Polymerization: Acts as a reactive emulsifier or stabilizer in the production of polymers like acrylics and styrene-acrylics.
• Lubricant Additives: Intermediate for creating sulfonate-based additives that provide detergency and anti-wear properties.
• Oilfield Chemicals: Potential use in formulating drilling mud surfactants and enhanced oil recovery (EOR) chemicals.

Quality Control

Our 2-Sulphopalmitic Acid is produced under a stringent quality management system. Each batch is tested to ensure consistent purity, composition, and performance characteristics relevant to its use as a surfactant intermediate. Certificates of Analysis (COA) documenting key parameters such as assay, sulfonic acid content, and impurity profile are provided and 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 at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed to prevent absorption of atmospheric moisture. Keep away from strong bases and oxidizing agents.
