Description

Stearic Acid, Propoxylated, Phosphate is a specialized nonionic surfactant and emulsifier derived from stearic acid through propoxylation and subsequent phosphorylation. This chemical modification imparts unique properties, making it a highly effective stabilizer and dispersing agent in complex formulations. It is essential for manufacturers in the personal care, coatings, and industrial lubricant sectors seeking to improve product stability and performance. Its multifunctional nature allows it to act as a coupling agent and viscosity modifier in demanding applications.

Application

• Primary emulsifier and stabilizer in cosmetic creams, lotions, and sunscreens.
• Key dispersing agent for pigments and fillers in industrial coatings and inks.
• Additive in metalworking fluids and synthetic lubricants for enhanced lubrication and corrosion inhibition.
• Processing aid and internal lubricant in PVC and other polymer formulations.
• Emulsifier and texturizer in certain food-grade release agents and packaging coatings (subject to specific grade and regulatory approval).
• Component in agricultural adjuvant formulations to improve pesticide spreading and adherence.
• Intermediate for the synthesis of more complex phosphate ester surfactants.

Quality Control

Our Stearic Acid, Propoxylated, Phosphate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistency, purity, and performance. Key parameters such as acid value, phosphate content, and hydroxyl value are monitored. Certificates of Analysis (COA) documenting these specifications are available for every shipment upon request, providing full traceability and compliance assurance for your quality protocols.

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 hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent absorption of atmospheric moisture. Keep away from strong alkalis and incompatible materials.
