Description

Potassium 9,10-Dihydroxystearate is a potassium salt derivative of dihydroxystearic acid, functioning as a specialized anionic surfactant and emulsifier. This compound is valued for its ability to modify surface tension and stabilize formulations, particularly in systems requiring compatibility with polar media. It is primarily sought by manufacturers in the personal care, cosmetics, and industrial lubricant sectors for its emulsifying and conditioning properties.

Application

• Cosmetic & Personal Care Formulations: Acts as a primary or co-emulsifier and skin-conditioning agent in creams, lotions, and ointments.
• Industrial Lubricants & Metalworking Fluids: Serves as an emulsifier and corrosion inhibitor in water-based lubricant systems.
• Textile Processing: Used as a softening agent, lubricant, and anti-static agent in fiber treatment and finishing.
• Paint & Coating Additives: Functions as a dispersing agent and stabilizer for pigments in aqueous coating formulations.
• Agricultural Adjuvants: Employed as a wetting agent and emulsifier in pesticide and herbicide formulations to enhance spray coverage.
• Soap & Detergent Specialties: Incorporated into specialty cleansing bars and syndet bars for its mildness and lather-boosting properties.

Quality Control

Our Potassium 9,10-Dihydroxystearate is manufactured under a strict quality management system. Each batch is tested to ensure it meets precise chemical and physical specifications, with a focus on purity, identity, and performance consistency. A comprehensive Certificate of Analysis (COA) documenting assay, impurity profile, and other critical parameters is provided with every shipment to guarantee traceability and compliance.

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) and must be kept in a dry environment to prevent caking and degradation. Keep away from strong oxidizing agents.
