Description

Polyhydroxystearic Acid is a high-purity, multifunctional fatty acid derivative valued for its excellent dispersing, emulsifying, and stabilizing properties. Its unique hydroxylated structure makes it a critical performance additive in formulations requiring superior compatibility and surface activity. This product is essential for manufacturers in the cosmetics, coatings, plastics, and specialty chemical industries seeking to enhance product stability and performance.

Application

• Cosmetics & Personal Care: Acts as a highly effective dispersant and stabilizer in color cosmetics (lipsticks, foundations), sunscreens, and creams, improving pigment wetting and formulation homogeneity.
• Coatings & Inks: Serves as a grinding aid and dispersing agent for pigments and fillers in solvent-based and high-solids coatings, improving color strength, gloss, and reducing settling.
• Polymer & Plastics Additive: Functions as an internal and external lubricant, anti-static agent, and release agent in PVC, polyolefins, and engineering plastics processing.
• Adhesives & Sealants: Used as a rheology modifier and compatibility agent to control flow properties and enhance filler dispersion.
• Lubricants & Greases: Employed as a thickening agent and performance additive to improve the stability and load-bearing characteristics of complex grease formulations.
• Specialty Chemical Intermediate: A key raw material for synthesizing esters, amides, and other derivatives used as non-ionic surfactants and emulsifiers.

Quality Control

Our Polyhydroxystearic Acid is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure consistent chemical and physical properties, including acid value, hydroxyl value, viscosity, and color. A Certificate of Analysis (COA) documenting these parameters is provided with each shipment to guarantee compliance with your specifications.

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 easily oxidized; for long-term storage, consider maintaining under an inert atmosphere (e.g., nitrogen blanket) to preserve product integrity. Keep away from strong oxidizers and heat sources.
