Description

6-Hydroxystearic Acid is a versatile hydroxylated fatty acid derivative, valued for its bifunctional chemical structure that provides both a carboxylic acid group and a hydroxyl group. This unique composition makes it a valuable intermediate for synthesizing specialized polymers, lubricants, and personal care ingredients, offering enhanced performance characteristics. It is particularly relevant for manufacturers in the cosmetics, pharmaceutical intermediates, and specialty chemical industries seeking to develop products with specific emulsifying, thickening, or surface-modifying properties.

Application

• Cosmetic & Personal Care Ingredients: Acts as a key intermediate in the production of emulsifiers, pearlescent agents, and viscosity modifiers for creams, lotions, and makeup.
• Polymer & Resin Modification: Used to synthesize polyesters and alkyd resins, imparting flexibility, adhesion, and specific rheological properties.
• Lubricant & Grease Additives: Serves as a precursor for ester-based lubricants and thickening agents, improving thermal stability and load-bearing capacity.
• Pharmaceutical Intermediates: Employed in the synthesis of certain bioactive compounds and controlled-release drug delivery systems.
• Surface Coatings: Incorporated into coatings and inks to enhance flow, leveling, and substrate wetting.
• Research & Development: Utilized as a standard or building block in chemical research for novel material science applications.

Quality Control

Our 6-Hydroxystearic Acid is produced under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for identity, purity, and composition. Certificates of Analysis (COA) documenting these results are provided to guarantee traceability and batch-to-batch consistency for your formulation needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. This material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect product quality. Recommended storage temperature: 15-25°C.
